5)

Answer:
B. None of these
Step-by-step explanation:
There are a total of 12 coins in your pocket.
The probability of drawing a nickel first is 5/12
Since you return the coin, the total number of coins in your pocket doesn't change.
The probability of drawing a dime second is 7/12
Since this is a compound probability problem, multiply the two probabilities together.
5/12 x 7/12 = 35/144
35/144 = 0.243

Each horse ride lasts 5 minutes with one minute pause in between for the next rider to get in the saddle . After every hour and a half the horses are given a rest . How many children can get an opportunity to ride a horse before they rest
Answer:
15 rides for each horse
Step-by-step explanation:
60 minutes in an hour
90 minutes in an hour and a half
6 minutes per ride (counting the re-saddle time )
90 min / 6 min/ride = 15 rides for each horse
Write the coordinates of the vertices after a rotation 270° counterclockwise around the origin.
Answer:
When rotating a rectangle 270° counter clockwise, you change the vertices in this way: (x,y) ---> (y,-x).
In other words, the "x" and "y" values switch, and the "x" becomes negative. If the "x" value is already negative, it becomes positive.

The volume of the solid will be equal to V=64 Cubic inches.
What is volume?The space occupied by any solid object in the three-dimension is called as the volume.
Here we have 8 cubes in the solid object each cube has the side equal to 2 inches.
So the volume of one cube will be:
V=a³=2³=8 cubic inches
Since total number of the cubes are 8 so total volume will be:
V=8x8=64 cubic inches
hence the total volume will be equal to 64 cubic inches`

Communicate Precisely: Suppose the numbers on the clock face are removed.
Write instructions that another person could follow to move the minute hand from 2 to 6.
In order to move the minute hand from 2 to 6 first move 60 degrees clockwise then 120 degrees clockwise.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
On a clock, numbers 1 to 12 are printed on it.
If numbers on the clock face are removed.
As we know, the clock is a circle and has a total angle of 360 degrees.
Angle between the two numbers = 360/12 = 30 degree
Then the following instructions have to be followed in order to move the minute hand from 2 to 6:
Set the minute hand vertically up.Move 60 degrees in a clockwise direction, it will be on number 2.Now move 120 degrees in a clockwise direction, it will indicate the number 6.Thus, in order to move the minute hand from 2 to 6 first move 60 degrees clockwise then 120 degrees clockwise.

Using complete sentences, describe how the variable h and the variable k of the general formula for a cube root function effects the graph. The general formula is;
y=a^(3)/sqrt(x-h+k)
Three possibilities
For red line
If h is negative then and k is positive then
then they will have two vertical asymptotes one on positive x and other on negative x
If h is negative and k is negative then the side part underroot with x turns negative I e x-(something) then they will form parabolas
You may look purple one
For all values of negative sum of h and k
example √x-k
The graph is parabola (Green one)
For h and k are equal the denominator yields √x and it stops at origin on downwards .(Blue one)
For all values of positive sum of h and k eg denominator as √x+k the graph will be like red one

Answer:
x = 4 and x = -3
Step-by-step explanation:
⇒ x² + x = 12
⇒ x² + x - 12 = 0
⇒ x² + 3x - 4x - 12 = 0
⇒ x(x + 3) - 4(x + 3) = 0
⇒ (x - 4)(x + 3) = 0
⇒ x = 4 and x = -3
Hey there!
x^2 + x = 12
SUBTRACT 12 to BOTH SIDES
x^2 + x - 12 = 12 - 12
SIMPLIFY IT!
x^2 + x - 12 = 0
SET the FACTORS to EQUAL to 0
x - 3 = 0 OR x + 4 = 0
SIMPLIFY IT!
x = 3 or x = -4
Therefore, the answer is:
x = 3 or x = -4

Answer:
Area = 50.125 cm^2
Perimeter = 26 + 15 = 41 cm
Step-by-step explanation:
Area Rectangle = 6 * 7 = 42 cm^2
Area Triangle = 1/2 * (9.5 - 7) * 6.5
Area Triangle = 1/2 * (2.5) * 6.5 = 8.125 cm^2
Total Area = 42 + 8.125 = 50.125 cm^2
Perimeter Rectangle = 6 + 7 + 6 + 7 = 26 cm
Perimeter or Triangle = 2.5 + 6.5 + 6 = 15 cm
Total Perimeter = 26 + 15 = 41 cm
The sum of two consecutive integers is 5.
What are the numbers?
Hint. Consecutive integers differ by 1,
so let x = smaller integer and y = x + 1 =
next larger.
They are 2 and 3, since 2 + 3 = 5
Let x be the smaller number. Then
x + (x + 1) = 5
2x + 1 = 5
2x = 4
x = 2
x + 1 = 3
1. Use the following table to answer the questions: (Note: f(x) is a continuous function)
[x] -2,3,4,8
[f(x)] 7, -2, 3, 6
[f'(x)]-4.5,-0.25,1,8
a. If g(x)=f(x), is g(x) a function?
b. Find f(g(4)).
c. Write the equation of the line tangent to g at x = -2.
PLEASE SEE PHOTO! Can you explain why my answers were wrong and can you find the correct answers to all of them?
1. a. No, g(x) is not a function because f(x) is not invertible. This is because it's not a monotonic function, which we gather from the table. On the interval [-2, 3], f(x) decreases from 7 to -2, but on the following interval [3, 4], f(x) increases to 3 and becomes positive once more. At best, f(x) is locally invertible.
1. b. This is impossible to determine... We can't know g(4) without knowing for which x we have f(x) = 4, but that's not included in the table.
1. c. The slope of the tangent line to f(x) at x = -2 is f'(-2) = -4.5. Then the equation of the tangent to f(x) at x = -2 - which means it passes through the point (-2, f(-2)) = (-2, 7) - is
y - 7 = -4.5 (x - (-2)) ⇒ y = -4.5x + 16
2. Given f(x) = arctan(3x) - ln(1 + 9x²), compute the derivative:
f'(x) = 3/(1 + (3x)²) - 18x/(1 + 9x²)
f'(x) = (3 - 18x)/(1 + 9x²)
Find the critical points of f(x), where f'(x) = 0 or doesn't exist. Only the first case can happen since the denominator is never zero. So
3 - 18x = 0 ⇒ x = 1/6
is the only critical point.
Also compute the second derivative, then check its sign at the critical point:
f''(x) = (-18 - 54x + 162x²) / (1 + 9x²)²
f''(1/6) = -72/5 < 0
The negative sign indicates that x = 1/6 is the site of a local maximum of
f(1/6) = arctan(1/2) - ln(5/4) ≈ 0.241
Also check the values of f(x) at the endpoints of the interval [0, 1]:
f(0) = 0
f(1) = arctan(3) - ln(10) ≈ -1.054
So, the maximum value of f(x) on [0, 1] is f(1/6) ≈ 0.241.

A. The word mean is the same as saying average. To find the average/mean add all the numbers together and then divide by the amount of numbers. For example, if your numbers were 2, 6, and 7. You would do 2+6+7=15. Then 15 divided by 3 is 5. The mean of those numbers is 5.
B. The median is the middle number. Put the numbers in a list from least to greatest and then find the one in the middle. For example, if your numbers were 1, 2, 3, 4, 5, 6, the median would be 3.
C. The mode is the most frequent number. Count how many of each number appears in the list, the one with the most is the mode. For example, if your numbers were 1, 1, 3, 8, 2, 1, the number 1 would be the mode because it appears the most frequently.
D. The range is the smallest number and the largest number. If your numbers were 2, 12, 46, and 9, the range would be 2-46 or 2 to 46.
I hope this helps you, let me know if you have any questions or would like another example! :)

What is the median of 0.8, 1.0, 2.7, 2.8, 3.1, 13.3
Answer:
[tex]2.75[/tex]
Step-by-step explanation:
Step 1: Determine the median
[tex]0.8, 1.0, 2.7, 2.8, 3.1, 13.3[/tex]
The median of a set is the middle of the set. In this instance, we have 6 numbers so we don't have a number directly in the set representing the median. Instead, we need to find the average or middle between the 3rd and 4th number. So we take 2.7 and 2.8, add them together to get 5.5 and then we divide by 2 to get 2.75 which is our median.
