A transformation is applied to a figure to create a new figure. Which transformation does not preserve congruence?

Answer:

10 cases

Step-by-step explanation:

We are given the equation: y = -0.25x + 85, where y is the # of cases, and x is the # of students who received the vaccine.

The question asks for the # of cases if 300 students received the vaccine. Since we know that 300 students received the vaccine, we can plug that in for x in the equation above, since x is that unit:

y = -0.25(300) + 85

Now, we can solve:

y = 10

Therefore, there will be 10 cases if 300 students received the vaccine.

The graph of the linear inequality is shown below.

What is linear inequality?

A linear inequality is one that, if the equals relation were employed in place of the inequality, would result in a linear equation. The direction of the inequality is reversed when both sides are multiplied or divided by a negative integer to solve it. The solution set refers to all possible answers to an inequality.

We are given y < -x-4

In order to sketch the graph of the inequality, we need to have two points.

So, first let's put x = 0

So, we get y = -4

Now, let's put y = 0

So, we get x = -4

Thus, we get the points as (0,-4) and (-4,0)

From the points, the graph is sketched which is shown below.

Hence, the graph of the linear inequality is obtained.

The function that best represents the value of the computer in months is V(t) = 1,300(.61^(t/12)).Where t is the number of months since the computer was purchased

The given function V(t) = 1,300(.61), models the value of a computer in terms of the number of years since it was purchased. The value of the computer is represented by the function V(t) which is directly proportional to (0.61) raised to the power of t. Divide the t by 12, because there are 12 months in a year, to get the value in months.

As a consequence, the calculation V(t) = 1,300(.61(t/12)) displays the computer's value in terms of months from purchase. It demonstrates the decline in the value of the computer over time.

a. The function of the bee population is: [tex]f(x) = 5000 * (1.12)^x[/tex]

b. To graph the function, f(x), you can use a graphing calculator or software such as Excel or a Python library like Matplotlib.

c. It will take approximately 7.9 months for Oscar to have 15,000 bees in the colony.

The problem states that Oscar wants to own a bee colony and extract honey from the hive. He starts with a colony of 5,000 bees and the number of bees grows exponentially with a growth factor of 12% each month. To solve this problem, we can use the exponential growth formula to determine the number of bees in the colony based on the month.

The exponential growth formula is [tex]P(t) = P_0 * (1 + r)^t[/tex] where

In this case, [tex]P_0[/tex] = 5000, r = 0.12, and t = x (the number of months). So, the function of the bee population is: [tex]f(x) = 5000 * (1.12)^x[/tex]

In order to get a decent amount of honey, Oscar feels that there should be at least 15,000 bees in the colony. To estimate how many months it will take Oscar until he has 15,000 bees, we can set f(x) = 15,000 and solve for x.

By doing this, we get x = log(15000/5000) / log(1.12) ≈ 7.9 months. This means it will take approximately 7.9 months for Oscar to have 15,000 bees in the colony.

It costs $0.208 more per hour to park in Lot A than in Lot B.

We know that the total parking hours = 48

Also, the cost of parking for Lot A= ($)19. 00/33. 00 and for Lot B = ($)20. 00/32. 00

To find out how many more dollars it costs per hour to park in Lot A than in Lot B, we will subtract the hourly rate of Lot B from the hourly rate of Lot A.

The hourly rate of Lot A is (33.00 - 19.00) / 48 = $0.541 (dollars and cents)

Similarly, the hourly rate of Lot B is (32.00 - 20.00) / 48 = $0.333 (dollars and cents)

So the difference in cost per hour is $0.541 - $0.333 = $0.208 (dollars and cents)

Therefore, it costs $0.208 more per hour to park in Lot A than in Lot B.

The missing measures by using the rhombus LMNO graphic is, 90° is the measure of LPM,the PMN measurement is 102°, LN is 10 units in length.

A rhombus is a unique type of quadrilateral with four sides that is similar to a parallelogram. In a rhombus, the opposing sides are parallel and the opposing angles are equal.

LMNO LON = 102° NP = 5 units for a rhombus.

According to the rhombic characteristics, all of the sides are congruent (equal), hence LM = MN = NO = OL and the opposite angles are also equal, and the opposite sides are parallel.

Therefore, LON = 102° = LMN.

Since adjacent angles add up to 180 degrees.

L + M thus equals 180 degrees.

∠M + ∠N = 180°

∠N + ∠O = 180°

∠O + ∠L = 180°

So, ∠N = 180° - ∠O = 180° - 102° =78°

∠L = 180° - ∠O = 180° - 102° =78°

∠M = 180° - ∠L = 180° - 78° =102°

Alternatively, we can say that each of the two diagonals in a rhombus is the perpendicular bisector of the other. Diagonals bisect each other at an angle of 90°.

Thus, LPM = NP0 = MPN = LPO = 90 degrees.

So, 90° is the measure of LPM.

The PMN measurement is 102°.

LN is 10 units in length.

The completre question is,

Rhombus LMNO has mLON = 102° and NP = 5 units.

The Rhombus L M N O is depicted. Drawn as parallel lines, they connect at point P and extend from point L to point N and from point M to point O, respectively. Congruence exists on every side.

The total cost is of the bicycles is given by -

$72 (cost of first bicycle) + $83 (cost of second bicycle) + $77 (cost of third bicycle) = $232

Now to find the average cost per bicycle, we will divide the total cost by the number of bicycles.

The concept that will be used here is Pythagorean theorem, sometimes known as Pythagoras' theorem, is a basic relationship between a right triangle's three sides in Euclidean geometry. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Pythagoras discovered that the square of the hypotenuse of a right-angled triangle, where one of the angles is 90 degrees, equals the sum of the squares of the other two sides:

And then the rectangle:

2 * 8

= 16

add the two areas together

15+16 = 31

Answer:

The three side lengths given, 12 ft, 16 ft, and 20 ft can form a right triangle. This is because the Pythagorean theorem states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. In this case, 20^2 = 12^2 + 16^2, so the sides 12 ft, 16 ft and 20 ft can form a right triangle.

The mean of the first population is not significantly larger than that of the second population. The p-value is 0.093.

Population 1: N = 35,X = 5.3, S = 2.8

Population 2: N = 21, X = 4.9, S = 3.2

We can use the t-test to test if the mean of the first population is larger than that of the second population. The formula for this is:

t = (x1 - x2) / (S√((1/N1) + (1/N2)))

Where x1 is the mean of population 1, x2 is the mean of population 2, S is the pooled standard deviation, and N1 and N2 are the sample sizes of the two populations.

Plugging in our values, we get:

t = (5.3 - 4.9) / (3.2√((1/35) + (1/21))) = 1.68

Using an online calculator, we find that the corresponding p-value is 0.093. Therefore, we fail to reject the null hypothesis that the two populations have the same mean and conclude that the mean of the first population is not significantly larger than that of the second population.
