What is p(8 or less than 7) write answer as a whole number
The expression "p(8 or less than 7)" suggests that we are looking for the probability of an event that satisfies one of two conditions: either the outcome is 8 or the outcome is less than 7. However, we need to know the specific probability distribution or situation in which this function p is being used to calculate a meaningful answer.
For example, if p represents the probability of rolling a certain number on a fair six-sided die, then p(8 or less than 7) would be 0, because 8 is not a possible outcome and all outcomes less than 7 are equally likely. However, if p represents the probability of a certain event occurring in a particular situation, then we would need more information about the nature of the event to calculate the probability.

Determine the total cost of the items if they were not sold to be as a combo if both are sold at R100 and when both sold at R100 you save R37
The total cost of the items if they were not sold as a combo is R137.
Let's assume that the individual prices of the two items are X and Y. Here we have to use the concept of algebraic equation. We have two unknowns (X and Y), and we use the information given about their combined cost and the savings made when sold as a combo to form an equation in terms of X and Y
When the items are sold individually, the total cost would be X + Y.
When the items are sold together as a combo, the cost is R100, and this saves R37 compared to the individual prices. This means:
X + Y - 37 = 100
Simplifying the above equation, we get:
X + Y = 137

a) The radius of the circle is r = 18 cm, b) angle AOC is a right angle, which is π/2 radians, c) the area of the shaded region is 125.66 cm², d) the perimeter of the shaded region is 57.85 cm.
Describe Circle?A circle is a two-dimensional geometric shape that is defined as the set of all points in a plane that are at a constant distance from a given point in the plane, called the center of the circle. The distance between the center of the circle and any point on the circle is called the radius of the circle. Alternatively, the diameter of a circle is the distance across the circle passing through the center, and it is twice the length of the radius.
A circle has several important properties, including:
Circumference: The circumference of a circle is the distance around its outer edge. It is calculated using the formula C = 2πr, where π (pi) is a mathematical constant approximately equal to 3.14 and r is the radius of the circle.
Area: The area of a circle is the amount of space inside its boundary. It is calculated using the formula A = πr², where π (pi) is the mathematical constant approximately equal to 3.14 and r is the radius of the circle.
a) To find the radius r, we can use the Pythagorean theorem to solve for the length of segment OP, which is the height of the rectangle:
OP² + AP² = OA²
OP² + 6² = r²
OP² = r² - 6²
We can also use the fact that AC is a diameter of the circle to find the length of segment OC:
AC = 2r
36 = 2r
r = 18
Substituting this value into the equation for OP² gives:
OP² = 18² - 6²
OP² = 300
OP = 10√3
Therefore, the radius of the circle is r = 18 cm.
b) Angle AOC is a central angle of the circle that intercepts segment AC. Since AC is a diameter, angle AOC is a right angle, which is π/2 radians.
c) The shaded region is the difference between the area of segment ABC and the area of triangle AOC. The area of segment ABC is equal to the area of sector AOC minus the area of triangle AOC. The area of sector AOC is:
(1/2) r² angle AOC
Substituting r = 18 cm and angle AOC = π/2 radians gives:
(1/2) (18)² (π/2) = 81π
The area of triangle AOC is:
(1/2) OA OC sin AOC
Substituting OA = OC = r = 18 cm and AOC = π/2 radians gives:
(1/2) (18)(18) sin(π/2) = 162
Therefore, the area of the shaded region is:
81π - 162 ≈ 125.66 cm²
d) The perimeter of the shaded region is the sum of the lengths of segments AB, BC, and the arc of the circle between A and C. To find the length of the arc, we can use the formula for the length of an arc of a circle:
length of arc = radius x central angle
Substituting r = 18 cm and angle AOC = π/2 radians gives:
length of arc = 18 x (π/2) = 9π
Therefore, the perimeter of the shaded region is:
AB + BC + length of arc = 36 + 2(6) + 9π ≈ 57.85 cm.

What is an inequality?
In mathematics, an inequality is a relationship that unfairly compares two numbers or other mathematical expressions. Size comparisons between two numbers on the number line are most usually made.
We are given an inequality as -4 < 4x < 20.
Now, on splitting the inequality, we get two inequalities which are:
-4 < 4x and 4x < 20.
On solving -4 < 4x, we get
⇒ -4 < 4x
⇒ -1 < x
Similarly, on solving 4x < 20, we get
⇒ 4x < 20
⇒ x < 5
So, we get -1 < x < 5 which means x ∈ (-1,5).

A veterinarian estimated the weight of a puppy to be 9kg. The actual weight of the puppy was 9.5kg Find the absolute error and the percent error of the veterinarian's estimate. If necessary, round your answers to the nearest tenth.
Answer:
The absolute error is the absolute value of the difference between the actual value and the estimated value:
Absolute error = |actual value - estimated value| = |9.5 kg - 9 kg| = 0.5 kg
The percent error is the absolute error expressed as a percentage of the actual value:
Percent error = (|actual value - estimated value| / actual value) x 100%
Plugging in the given values, we get:
Percent error = (0.5 kg / 9.5 kg) x 100% = 5.3%
Rounding to the nearest tenth, the absolute error is 0.5 kg and the percent error is 5.3%.

Answer:
a. The product of each pair of numbers is:
1 x 49 = 49
2 x 48 = 96
10 x 40 = 400
b. The pair of numbers that will produce the largest possible product is when the two numbers are equal to half of the sum, which is 25. So the pair of numbers is 25 and 25, and the product is 25 x 25 = 625.
c. We can determine the pair of numbers that have the largest product by using the following reasoning: For any two numbers whose sum is fixed, their product is maximized when the two numbers are as close together as possible. This is because the product of two numbers that are far apart is always smaller than the product of two numbers that are closer together and have the same sum. In this case, the sum is 50, so the two numbers that are closest together and add up to 50 are 25 and 25, which give the largest possible product.

how many ways can we place three rooks on a four by five board so that no rook is threating another?
There are 40 ways to place three rooks on a 4x5 board so that no rook is threatening another.
To determine this, we can first place the rooks in three distinct rows, which can be done in 4 * 3 * 2 = 24 ways. Then, we can place one rook in each of the five columns in the first row, which leaves only three columns for the second row and two columns for the third row.
Since no two rooks can be in the same column, we have 5 * 3 * 2 = 30 ways to place the remaining two rooks.
Therefore, the total number of arrangements is 24 * 30 = 720, but since each arrangement can be rotated by 90, 180, or 270 degrees, we need to divide by 4 to obtain the final answer of 720/4 = 180, and since there are two ways to arrange the rooks in each row, the final answer is 180/2 = 90.

Choir B has a higher percentage of students who like musicals.
what is percentage ?
Percentage is a way of expressing a proportion or a fraction out of 100. It is a widely used concept in mathematics, finance, statistics, and other fields. For example, if 20 out of 100 students in a class like pizza, we can say that the percentage of students who like pizza is 20%. To calculate the percentage, we usually multiply the given fraction by 100. For instance, if 3 out of 5 students like math, we can calculate the percentage of students who like math as follows:
(3/5) x 100 = 60%
Thus, 60% of the students in the class like math.
To determine which choir has a higher percentage of students who like musicals, we need to calculate the percentage of students in each choir who like musicals.
For choir A, 39 out of 52 students like musicals:
39/52 = 0.75 or 75%

A train is moving at a rate of 65 miles/hour toward a railroad marker located 200 miles away. Which equation could be used to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart, where h represents the time in hours?
The distance d between the train and the railroad marker can be expressed as:
d = 200 - 65h
where 200 represents the initial distance between the train and the marker, and 65h represents the distance the train has covered after h hours, assuming a constant speed of 65 miles per hour.
To find the time it will take for the distance between the train and the marker to be 4 miles apart, we can set d to 4 and solve for h:
4 = 200 - 65h
65h = 196
h = 196/65
So the equation to find the time it will take for the distance between the train and the railroad marker to be 4 miles apart is:
200 - 65h = 4
or
65h = 196

In a lab experiment, 80 bacteria are placed in a petri dish. The conditions are such that the number of bacteria is able to double every 5 hours. How long would it be, to the nearest tenth of an hour, until there are 136 bacteria present?
Answer:
Step-by-step explanation:
We can use the formula for exponential growth to solve this problem:
N = N0 * 2^(t/T)
where N is the final number of bacteria, N0 is the initial number of bacteria, t is the time elapsed, and T is the doubling time.
We know that N0 = 80, and T = 5 hours. We want to find t when N = 136.
136 = 80 * 2^(t/5)
Dividing both sides by 80, we get:
1.7 = 2^(t/5)
Taking the logarithm of both sides (base 2), we get:
log2(1.7) = t/5
Solving for t, we get:
t = 5 * log2(1.7) ≈ 3.4 hours
Therefore, it would take approximately 3.4 hours, to the nearest tenth of an hour, until there are 136 bacteria present.
