Answer:
See graph
Step-by-step explanation:
The transformation is as follows
The transformation of h(x) to -h(x) - 4 is a combination of two transformations
1. A reflection around the x -axis. Every point(x, y) in h(x) becomes (x', y') where x' = x and y' = -y so (x, y) → (x, -y)
2. A translation of each reflected point 4 units down; x value does not change but y values are shifted down so the new y is y'-4 = -y -4
The result of both transformations is:
every coordinate (x, y) in h(x) will be transformed to (x, -y -4)
Seeing as the graph consists of two straight lines meeting at the origin, all we need to do is take any 3 points in h(x), find the transformed coordinates and connect them with straight ilnes
h(x0 -h(X) - 4
(-2, 4) ⇒ (-2, -4-4) = (-2, -8)
(0, 0 ) ⇒ (0, -0 - 4) = (0, -4)
(4, 2) ⇒ (4, -2 -4) = (4, -6)
take these three points and plot

Hint: Use the image to help break 9 x 4 up into two expressions.
9x4
5 fours +
fours
Answers
Based on the image, we can break 9 × 4 into two expressions as 4 groups of 9 or 9 groups of 4. This equals 36.
How to explain the expressionIt should be noted that to break 9 x 4 up into two expressions, you can use the distributive property of multiplication over addition, which states that a(b + c) = ab + ac.
So, we can rewrite 9 x 4 as:
9 x 4 = 9 x (3 + 1)
Using the distributive property, we can expand this expression as:
9 x (3 + 1) = (9 x 3) + (9 x 1)
Simplifying, we get:
9 x 4 = 27 + 9
Therefore, we have broken up 9 x 4 into two expressions: 27 and 9. This will give 36.

Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah a total of 4 people took the trip. She was able to purchase coach tickets for $140 and first class tickets for $1000. She used her total budget for airfare for the trip, which was $2280. How many first class tickets did she buy? How many coach tickets did she buy?
number of first class tickets bought = ___
Answers
The number of coach tickets purchased is 3, and the number of first-class tickets purchased is 8.
Let us assume the number of coach tickets purchased is x.
And the number of first-class tickets purchased is y.
Now,
Including Sarah, a total of 11 people took the trip.
Thus,
[tex]x + y = 11 [/tex]
The cost of coach tickets and first-class tickets are $210 and $1200 respectively.
The total budget for airfare for the trip is $10,230.
Therefore,
210x + 1200y = 102309
21x + 120y = 1023
Solving both the equations, we get.
x=3
y=8
Thus, The number of coach tickets purchased is 3, and the number of first-class tickets purchased is 8.

The inequality that has a dashed boundary line when graphed is:
y > 3x + 1
What is inequality?In mathematics, an inequality is a statement that two quantities are not equal or do not have the same value. In other words, it is a statement that compares two values, expressing that one value is greater than, less than, or not equal to the other value. An inequality is denoted by symbols such as < (less than), > (greater than), ≤ (less than or equal to), and ≥ (greater than or equal to).
What is Dashed boundary?In mathematics, a dashed boundary refers to a boundary line that is graphed as a dashed line rather than a solid line. The use of a dashed line is typically used to indicate that the boundary itself is not included in the set of solutions of an inequality or equation.
In the given question,
The inequality that has a dashed boundary line when graphed is:
y > 3x + 1
The reason for this is that when graphed, the boundary line of the inequality y > 3x + 1 is a straight line, but it is dashed instead of solid. This is because the inequality is strict, meaning that the boundary line itself is not included in the set of solutions. On the other hand, if the inequality had been y ≥ 3x + 1, the boundary line would have been a solid line because the inequality is non-strict and includes the boundary line itself as a solution.

Blood pressure readings are normally distributed. The mean systolic blood pressure is 120 and the standard deviation is 8. If a medical researcher randomly selects a sample of 20 people, what is the probability that the mean blood pressure for this sample will be greater than 123?
Answers
Answer:
To solve this problem, we can use the central limit theorem and the standard normal distribution.
The central limit theorem states that the distribution of sample means is approximately normal, with a mean equal to the population mean, and a standard deviation equal to the population standard deviation divided by the square root of the sample size.
Let X be the systolic blood pressure of an individual in the population. We know that X is normally distributed with a mean of 120 and a standard deviation of 8.
Let Y be the sample mean blood pressure of a sample of 20 individuals. Then Y is also normally distributed, with a mean of 120 and a standard deviation of 8 / sqrt(20) = 1.7889.
We want to find the probability that the sample mean blood pressure is greater than 123. We can standardize this value using the standard normal distribution as follows:
Z = (Y - 120) / (8 / sqrt(20))
P(Y > 123) = P(Z > (123 - 120) / (8 / sqrt(20)))
= P(Z > 1.3363)
Using a standard normal distribution table or calculator, we can find that the probability of Z being greater than 1.3363 is approximately 0.0918.
Therefore, the probability that the mean blood pressure for a sample of 20 people will be greater than 123 is approximately 0.0918.
Find m1 if m5 =142 and m4=65
Answers
The value of m∠1 is 103°. The solution has been obtained by using the angle sum property.
What is the angle sum property?
The angle sum property of a triangle states that the sum of the three internal angles of a triangle is 180 degrees.
We are given that m∠5 = 142° and m∠4 = 65°.
Since m∠5 and m∠2 lie on a straight line so, they form a linear pair.
So,
⇒ m∠5 + m∠2 = 180°
⇒ 142° + m∠2 = 180°
⇒ m∠2 = 38°
We know that sum of angles of a triangle is 180°.
So,
⇒ m∠3 + m∠4 + m∠2 = 180°
⇒ m∠3 + 65° + 38° = 180°
⇒ m∠3 + 103° = 180°
⇒ m∠3 = 77°
Now, since m∠3 and m∠1 lie on a straight line so, they form a linear pair.
So,
⇒ m∠3 + m∠1 = 180°
⇒ 77° + m∠1 = 180°
⇒ m∠1 = 103°
Hence, the value of m∠1 is 103°.

b. has multiple predictors
c. requires a linear relationship between the predictor and the dependent variable
Answers
Answer:
Option b
Explanation:
c. requires a linear relationship between the predictor and the dependent variable is not true about a polynomial regression model.
Polynomial regression models allow for non-linear relationships between the predictor and dependent variable by adding polynomial terms to the model. This means that polynomial regression models can capture non-linear relationships that linear regression models cannot.
Therefore, option a is true. Polynomial regression models can also have multiple predictors, so option b is true.

The length of the side opposite to the 42 degree angle in the right triangle is approximately 3.4 units.
Describe Triangle?The angles of a triangle are the angles formed by its sides. The sum of the angles of a triangle is always 180 degrees, which is a fundamental property of this shape. There are different types of triangles, based on their side lengths and angle measures. For example:
A scalene triangle has three sides of different lengths and three different angles.
An isosceles triangle has two sides of equal length and two equal angles.
An equilateral triangle has three sides of equal length and three equal angles.
A right triangle has one angle that measures 90 degrees (a right angle), and the side opposite to it is called the hypotenuse.
Triangles have many important properties and applications in mathematics, physics, and engineering. They can be used to calculate distances, angles, areas, volumes, and many other quantities. Triangles are also used in the construction of buildings, bridges, and other structures, as well as in art, design, and other fields.
We can use the trigonometric ratio of sine to solve for x:
sin(42) = opposite/hypotenuse
sin(42) = x/5
To solve for x, we can multiply both sides by 5 and simplify:
x = 5*sin(42)
x ≈ 3.4 (rounded to the nearest tenth)
Therefore, the length of the side opposite to the 42 degree angle in the right triangle is approximately 3.4 units.

What is the Gaussian method?
The Gaussian method, also known as Gaussian elimination or row reduction, is a technique for solving systems of linear equations. It involves performing a sequence of operations on the rows of a matrix to transform it into an equivalent matrix that is in row echelon form or reduced row echelon form.
To use the Gaussian method, we need to set up a system of linear equations based on the given information. Let x, y, and z be the number of units of Metakeb, Mewesson, and Metekem produced per month, respectively. Then we have:
Machining department: 1200x + 1800y + 3000z = 1050(60)
Inspection department: 2400x + 1200y = 1160(60)
Assembly department: 600x + 3000y = 830(60)
Simplifying these equations, we get:
Machining department: 20x + 30y + 50z = 3150
Inspection department: 8x + 4y = 232
Assembly department: x + 5y = 139
Now we can use the Gaussian method to solve for x, y, and z:

A hardware store sells nylon rope for $0.89/yd. A lumber yard sells the same rope for $0.94/m.
a) Which store sells the rope for a lower price? Explain your answer.
b) How much money would Jim save if he purchased 650 ft. of the less expensive rope, before taxes?
pls complete a and b!!
Answers
Therefore , the solution of the given problem of unitary method comes out to be 14.7 dollars before taxation, assuming he bought 650 feet of the cheaper rope.
What is an unitary method?The job can be completed by bringing together what was learned and applying this variable technique, that also includes all supplementary data from two people that utilized a specific tactic. To put it another way, if the desired outcome materialises, either the entity stated in the calculation will be recognised, or both expression essential processes will truly skip the colour. For forty pencils, a refundable charge of Rupees ($1.01) might be required.
Here,
To evaluate the prices, we need to use the same units.
Since 0.9144 metres make up one yard, we can convert the cost of the rope at the hardware shop to dollars per metre as follows:
=> 0.89 dollars/yard * 1 yard/0.9144 meters = 0.97 dollars/meter
b) We must change the units to yards or metres in order to evaluate the costs of 650 feet of rope. 650 feet is equivalent to 3 yards, which is:
=> 650 feet x 3 feet per yard = 216.67 yards
The hardware store's price for the cord is:
=> 192.5 dollars ($0.89/yard x 216.67 yards)
At the timber yard, the price of the rope is:
=> (216.67 yards * 0.9144 meters/yard) * 0.94 dollars/meter = 177.8 dollars.
Jim would therefore save:
=> 192.5 dollars - 177.8 dollars = 14.7 dollars.
before taxation, assuming he bought 650 feet of the cheaper rope.

Theoretical propobility
Answers
Theoretical probability is the likelihood of an event occurring based on mathematical reasoning or analysis, rather than on empirical or experimental data.
What is probability?Probability refers to the likelihood of a particular event or outcome occurring. It is a measure of the chance of an event happening, and is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event. The probability of an event can be determined by dividing the number of favorable outcomes by the total number of possible outcomes. Probability is used in many fields, including mathematics, statistics, physics, engineering, and finance, to make predictions and inform decision-making.
Here,
It is calculated using the laws of probability and assumes that all outcomes are equally likely to occur. Theoretical probability is often used in situations where it is not possible or practical to conduct experiments or collect data, such as in mathematical or statistical modeling.

Answers
The vertical shape of the graph will be the same as that of the first rocket, assuming both rockets have the same initial velocity and acceleration.
What is the interval during which all three rockets?1.I agree with Serena that we can draw the graphs for the other two rockets by shifting the functions. We can use the same equation and just adjust the values of the horizontal and vertical shifts.
2. The equation f(t) = -6t² represents a quadratic function, which has a parabolic shape when graphed. If we apply a transformation to this function, such as a vertical or horizontal shift, the shape of the graph will change accordingly.
3. The term 82.14 likely represents the maximum height achieved by the rocket, since the equation f(t) = -6t² gives the height of the rocket as a function of time. The value of h(t) = 82.14 corresponds to a specific time when the rocket reaches its maximum height.
4. If the second rocket is launched 3 seconds after the first one, the graph of the second rocket will be shifted horizontally by 3 units to the right compared to the graph of the first rocket. This represents a time delay of 3 seconds between the two launches.
5. The equation of the second rocket would be f(t) = -6(t-3)², assuming that the second rocket has the same initial velocity and acceleration as the first rocket but is launched 3 seconds later.
6. Since the third rocket is launched 3 seconds after the second rocket and from a tall platform, its graph will be shifted horizontally to the right by 6 units compared to the graph of the first rocket.
9. A: Based on the graph, the third rocket was launched at approximately 5:20 PM.
B: Based on the graph, the first rocket lands at approximately 5:15 PM.
C: Based on the graph, all three rockets are in the air between approximately 5:10 PM and 5:25 PM, so the approximate interval during which all three rockets are in the air is 15 minutes.
Therefore, spends an additional 6 seconds in the air before landing. The vertical shape of the graph will depend on the specifics of the rocket's launch and trajectory.

An engineer has designed a valve that will regulate water pressure on an automobile engine. The valve was tested on 240 engines and the mean pressure was 4.6 lbs/square inch. Assume the variance is known to be 0.81 . If the valve was designed to produce a mean pressure of 4.7 lbs/square inch, is there sufficient evidence at the 0.02 level that the valve does not perform to the specifications? State the null and alternative hypotheses for the above scenario.
Answers
We reject the null hypothesis and come to the conclusion that there is adequate evidence at the 0.02 level.
What does hypothesis testing's Type I error and Type II error mean?The rejection of a correct null hypothesis during hypothesis testing is referred to as a Type I mistake. As a result, we get the incorrect conclusion that there is a large difference between two groups or variables. A false positive is another name for a Type I mistake.
Failure to reject a faulty null hypothesis is a Type II mistake. This means that we get the incorrect conclusion that there is no difference between two groups or variables when there actually is one. False negative is another name for a Type II mistake.
The valve generates a mean pressure of 4.7 lbs/square inch, which is the null hypothesis:
H0: μ = 4.7
The other possibility is that the valve does not generate 4.7 lbs/square inch of mean pressure:
Ha: μ ≠ 4.7
Since we are comparing the single sample mean to a known population mean and we are aware of the population variance, we can test this hypothesis using a one-sample t-test. The test statistic is determined by dividing the sample mean (x) by the population mean, the sample size (n), and the population standard deviation (s).
We obtain the following by plugging in the values:
t = (4.6 - 4.7) / (0.9 / √(240))
t = -4.15
Using a two-tailed test and a t-distribution table with 239 degrees of freedom (240 - 1), we can get the crucial t-value as follows:
T critical equals 2.571
We reject the null hypothesis and come to the conclusion that there is adequate evidence at the 0.02 level that the valve does not operate in accordance with specifications since our computed t-value (-4.15), which is in the rejection area (t -2.571 or t > 2.571), falls within this range.
