Answer:
a) There are four prime numbers between 1 and 10: 2, 3, 5, and 7. So the probability of drawing a prime number is 4/10 or 2/5, which is 20% and not 10%. Therefore, option (a) is not correct.
b) As we saw in part (a), the probability of drawing a prime number is 2/5 or 40% (since 2/5 is equivalent to 0.4). Therefore, option (b) is correct.
c) The probability of drawing a prime number is 2/5 or 40%, which is not 25%. Therefore, option (c) is not correct.
d) As we saw in part (a) and (b), the probability of drawing a prime number is 2/5 or 40%, which is not 50%. Therefore, option (d) is not correct.
So, the correct answer is (b) 25%.

What is the measurement of the fourth angle of a quadrilateral if the other angle’s measure 80 degrees 120 degrees and 65 degrees?
the measurement of the fourth angle of the quadrilateral is 95 degrees.
To find the measurement of the fourth angle of a quadrilateral when the measures of three angles are given, we can use the fact that the sum of the measures of the angles in a quadrilateral is 360 degrees.
Let's denote the measure of the fourth angle as x. Then we can write an equation:
80 + 120 + 65 + x = 360
Simplifying this equation, we get:
x = 360 - 80 - 120 - 65 = 95
Therefore, the measurement of the fourth angle of the quadrilateral is 95 degrees.

Two buses leave a station at the same time and travel in opposite directions. One bus travels 18 miles hour faster than the other. If the two buses are 768 miles apart after 6 hours, what is the rate of each bus?
Answer: the slower bus travels at 55 miles per hour and the faster bus travels at 73 miles per hour.
Step-by-step explanation:
distance = rate x time
768 = 6x + 6(x + 18)
Simplifying this equation, we can distribute the 6 on the right-hand side:
768 = 6x + 6x + 108
Combining like terms, we get:
768 = 12x + 108
Subtracting 108 from both sides:
660 = 12x
Dividing both sides by 12:
x = 55
So the slower bus is traveling at 55 miles per hour. To find the speed of the faster bus, we can add 18:
x + 18 = 55 + 18 = 73
Answer: one is 55 and the other is 73
Step-by-step explanation:
lets say x is for the slower bus. for every hour the become x+x+18
and this is happening for 6 hours so its is 6(2x+18)=768
x=55
x+18=73

A 5/6
B 4/5
C 3/4
D 1/5
After answering the provided question, we can conclude that As a result, function option A) 5/6 is the correct answer.
what is function?A function appears to be a hyperlink between two sets of numbers in mathematics, where each member of the first set (referred as the domain) corresponds to a certain representative of the second set (called the range). In other utterance, a function takes input from a set and produces output by another. Inputs are frequently represented by the variable x, and outputs are represented by the variable y. A function can be represented by a formula or a graph. The method y = 2x + 1 is an example of a conceptual model in which each value assigned to x yields a value of y.
Both Glass A and Glass B initially hold the same amount of liquid. Assume that the total amount of liquid that each glass can hold is equal to 6 units.
As a result, Glass A is initially filled with 3 units of liquid (1/2 of 6 units) and Glass B is initially filled with 2 units of liquid (1/3 of 6 units).
When the liquid from Glass B is poured into Glass A, the total amount of liquid in Glass A increases to 5 units (3 units + 2 units), and the glass is now completely filled.
So, after pouring the liquid from Glass B into it, the fraction of Glass A that is filled is 5/6.
As a result, option A) 5/6 is the correct answer.

Find the value of the derivative (if it exists) at the indicated extremum. (If an answer does not exist, enter DNE.)
The calculated value of the derivative f'(x) at x = -2/3 if f(x) = 5x√(x + 1) is f'(-2/3) = 0
How to find the value of the derivativeGiven the function
f(x) = 5x√(x + 1)
Factor out 5
So, we have
f(x) = 5[x√(x + 1)]
The derivative is then calculated using the following chain rule
f'(x) = 5[du/dx * dy/du]
When differentiated, we have
f'(x) = 5[√(x + 1) + x/2[√(x + 1)]]
This gives
f'(x) = 5[3x + 2/2[√(x + 1)]]
So, we have
f'(x) = [15x + 10]/[2√(x + 1)]
Substitute -2/3 for x
f'(-2/3) = [15(-2/3) + 10]/[2√((-2/3) + 1)]
Evaluate
f'(-2/3) = [0]/[2√1/3]
Evaluate the quotient
f'(-2/3) = 0
Hence, the value of the derivative is 0

Point B (8, -3) has been transformed. After a reflection over the x-axis, what is the coordinate of point B’?
The coordinate of point B' is (8, 3) after reflecting point B (8, -3) over the x-axis.
What is Reflection in geometry?A reflection is an involution: when applied twice in succession, every point returns to its original location, and every geometrical object is restored to its original state.
When a point is reflected over the x-axis, its y-coordinate changes sign while its x-coordinate remains the same.
Therefore, to find the coordinates of point B' after reflecting point B over the x-axis, we simply need to change the sign of the y-coordinate of point B.
Starting with point B at (8, -3), reflecting over the x-axis changes the sign of the y-coordinate, so the new point B' is at:
B' = (8, 3)
Therefore, the coordinate of point B' is (8, 3) after reflecting point B (8, -3) over the x-axis.

A(r(t))=\pi(0.25+2t+4t^2)
Explanation:
To write a composite function, we apply one function to another given function. In this case, we want to find area in terms of time; this means that the function A(r) gets applied to the function r(t).
In order to do this, we replace r with r(t). We already know that r(t)=0.5+2t; this means we replace r with 0.5+2t:
A(r(t))=π(0.5+2t)²
To simplify this, we simplify the squared term:
A(r(t)) = π(0.5+2t)(0.5+2t)
A(r(t)) = π(0.5*0.5+0.5*2t+2t*0.5+2t*2t)
A(r(t)) = π(0.25+t+t+4t²)
A(r(t)) = π(0.25+2t+4t²)
Answer:
So the composite function that gives the area of a circle in terms of time is:
A(r(t)) = π(0.25+2t+4t²)

Part A
Which equation can be solved to predict the number of times Harris will spin a sum less than 10?
A) 3/500 = x/15
B) 12/500 = x/15
C) 12/15 = x/500
D) 3/15 = x/500
QUESTION 2
Part B
How many times should Harris expect to spin a sum that is 10
or greater?
_______
The equation that can be solved to predict the number of times Harris will spin a sum less than 10 is B) 12/500 = x/15
Harris should expect to spin a sum of 10 or greater 240 times.
How to explain the equationIt should be noted that to predict the number of times Harris will spin a sum less than 10, we need to find the probability of getting a sum less than 10 and multiply it by the total number of experiments (500).
The possible sums that can be obtained are: 5, 6, 7, 8, 9, 10, 11, and 12. The probability of getting a sum less than 10 is the sum of the probabilities of getting each of these outcomes, which is:
P(sum less than 10) = P(1 and 4, 1 and 5, 2 and 4, 2 and 5, 3 and 4, 3 and 5)
= 6/15 * 2/5
= 4/25
Multiplying this probability by the total number of experiments (500), we get:
Number of times Harris will spin a sum less than 10 = (4/25) * 500 = 80
Therefore, the correct equation to predict the number of times Harris will spin a sum less than 10 is: 12/500 = x/15
Part B: Based on the information, the possible outcomes that give a sum of 10 or greater are: 10, 11, and 12. The probability of getting a sum of 10 or greater is the sum of the probabilities of getting each of these outcomes, which is:
P(sum of 10 or greater) = P(1 and 9, 2 and 8, 3 and 7, 4 and 6, 5 and 5, 6 and 4, 7 and 3, 8 and 2, 9 and 1, 8 and 3, 7 and 4, 6 and 5)
= 12/15 * 3/5
= 36/75
= 12/25
Multiplying this probability by the total number of experiments (500), we get:
Number of times Harris should expect to spin a sum of 10 or greater = (12/25) * 500 = 240
Therefore, Harris should expect to spin a sum of 10 or greater 240 times.

Find the total surface area of this cylinder. Give your answer to 1 decimal place. 18 cm Feedback 24 cm
In light of this, the cylinder's total surface area falls between approximately 1017.9 cm²and 1357.2 cm².
Define the cylinder's entire surface area.A cylinder's total surface area is equal to the sum of all of its faces' surface areas. The cylinder's total surface area—the sum of its curved and circular areas—has a radius of "r" and a height of "h." The entire surface area of the cylinder is calculated as follows:
Define cylinder:Total Surface Area of Cylinder = 2r (h + r) square units.
The three-dimensional shape of a cylinder is made up of two parallel circular bases connected by a curved surface. It is seen as a prism since its base is a circular. It is frequently used as a container and can either be solid or hollow 13.
The following formula can be used to get a cylinder's total surface area:
A = 2πr² + 2πrh
where r is the cylinder's base's radius, h is the cylinder's height, and is a mathematical constant roughly equal to 3.14159.
Yet, we can locate a variety of potential surface areas using the provided information. With the assumption that the radius is equal to the feedback's half (9 cm), we can
after which, we can determine the surface area as follows:
A = 2π(9)² + 2π(9)(18) (18)
A= 2π(81) + 2π(2916)
A ≈ 1017.9 cm²
The surface area can be calculated as follows if we assume that the radius is equal to two-thirds of the feedback (i.e., r = 12 cm):
A = 2π(12)² + 2π(12)(18) (18)
A ≈ 1357.2 cm²

Let's call the weight of Karen's package "w" in pounds.
For the first courier, the cost is given by:
Cost = 20 + 2w
For the second courier, the cost is given by:
Cost = 12 + 3w
We know that these costs are equivalent, so we can set them equal to each other:
20 + 2w = 12 + 3w
Simplifying this equation, we get:
8 = w
So the weight of Karen's package is 8 pounds.
To find the cost, we can plug this weight into either of the equations above:
For the first courier:
Cost = 20 + 2(8) = 36
For the second courier:
Cost = 12 + 3(8) = 36
So it will cost Karen $36 to deliver her package, and the weight of the package is 8 pounds.
Find an angle in each quadrant with a common reference angle with 165°, from 0°≤θ<360°
Answer:
Here are the angles in each quadrant with a common reference angle of 165°:
First quadrant: angle is 15° (subtract 165° from 180°)
Second quadrant: angle is 195° (subtract 165° from 180° and add the result to 180°)
Third quadrant: angle is 195° (subtract 165° from 180° and then subtract the result from 180°)
Fourth quadrant: angle is 195° (subtract 165° from 360°)
