The likelihood that exactly 13 students will pursue arts in the coming year is 76.47%.
What do we mean by probability?Probability is simply the likelihood of something occurring. When we are uncertain about the outcome of an event, we can discuss the probabilities of various outcomes—how probable they are. Statistics is the study of events governed by probability.So, to find the probability:
Given:
Each year, there are 17 students who study art.We now want to calculate the likelihood that 13 students will pursue arts in the following year.
That is,
P(13 will take art the next year) = 13/17 × 100%P(13 will take art the next year) = 76.47%Therefore, the likelihood that exactly 13 students will pursue arts in the coming year is 76.47%.

The value of the exponential expression is 4 which is option (C).
Exponential equations, as the name suggests, involve exponents. The exponent (radix) of a number indicates how many times the number (radix) is multiplied.A number's exponent indicates how many times the number has been multiplied by itself. For example, 2×2×2×2 can be written as 24 because 2 is multiplied by 4. Here 4 is called the "exponent" or "power". In general, xn means multiply x by n times.

Answer:

Step-by-step explanation:
Determine the solutions of the equation:
x = −11 and x = 5
x = −81 and x = 45
x = −99 and x = 45
x = −99 and x = 99
The solutions of the absolute value equation are x = −99 and x = 45.
How to determine the solutions of the absolute value equation?Here we have the absolute value equation:
| (1/3)*x + 9| - 3 = 21
First, we can add 3 in both sides so we get:
| (1/3)*x + 9| = 21 + 3 = 24
This can be decomposed into two equations, we will get:
(1/3)*x + 9 = 24
(1/3)*x + 9 = -24
Solving these two we can get the two solutions.
The first one gives.
(1/3)*x = 24 - 9 = 15
x = 3*15 = 45
The second one gives:
(1/3)*x = -24 - 9 = -33
x = 3*-33 = -99
The solutions are x = −99 and x = 45.

The table shows the proportional relationship between a hedgehog's
weight loss and the number of days of hibernation. How much weight does
the hedgehog lose during 120 days of hibernation?
Explain how you know that the relationship between the hedgehog's weight
loss and the number of days of hibernation is proportional.
The hedgehog’s total change in weight over 120 days is ____ ounces.
Answer:
-3.6
Step-by-step explanation:
proportional means the amount on the right is amount on the left multiplied by some coefficient - proportion. The proportion is calculated by dividing one side by another. Since you need to calculate weight based on days, you need the proportion of weight/days, so divide -0.27/9 or -0.78/26, in all cases you'll receive -0.03. This means for each day in hibernation hedgehog loses 0.03 pounds. 120 days will be 120*-0.03 which gives you -3.6

find the volume of the parallelepiped with adjacent edges pq, pr, and ps. p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), s(3, 6, 1)
The volume of the parallelepiped with adjacent edges PQ, PR, and PS is 24 cubic units.
What is parallelepiped?Six parallelograms come together to form a three-dimensional shape called a parallelepiped (the term rhomboid is also sometimes used with this meaning). It is comparable to a parallelogram in the same way that a cube is comparable to a square. In Euclidean geometry, the four concepts—parallelepiped and cube in three dimensions, parallelogram, and square in two dimensions—are specified; however, only parallelograms and parallelepipeds exist in the setting of a more generic affine geometry, where angles are not discriminated.
There are three similar descriptions of a parallelepiped:
A polyhedron called a hexahedron, which has six parallelogram-shaped facesThree pairs of parallel faces on a hexahedron, andA prism with a parallelogram as its base.We have been that p(−2, 1, 0), q(4, 4, 4), r(1, 4, −1), and s(3, 6, 1) are the adjacent edges of parallelepiped

==================================================
Explanation:
The rule we use is [tex](\text{x}, \text{y}) \to (-\text{x}, \text{y})[/tex] when reflecting over the vertical y axis.
The x coordinate flips from positive to negative, or vice versa. The y coordinate stays the same. So a point like (-6, 5) reflects over to (6, 5). The x coordinate -6 flipped to +6 or simply 6. The y coordinate stayed at 5.
Use this idea to reflect the other points.
Mardi received an inheritance of $60,000. she investrf part at 11% and deposited the remainder in tax-free bonds at 12%. her total annual income from the investments was $6800. find the ammount invested at 11%.
When Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800as annual income then the amount invested at 11% is $20000
Given,
The total amount Mardi received = $60000
She invested part at 11% and deposited the remainder in tax-free bonds at 12%.
Annual income from the investment = $6800
Consider the part of money invested at 11% as x
Then the equation will become
(60000-x)0.11+0.12x =6800
6600-0.11x+0.12x =6800
0.01x+6600=6800
0.01x=200
x= $20000
Hence, when Mardi received an inheritance of $60000, she invested part at 11% and deposited the remainder in tax-free bonds at 12%, so she gets $6800 as annual income then the amount invested at 11% is $20000

Time taken to run from mile marker 1 to mile marker 2 = 8 minutesTime taken to run from mile marker 2 to mile marker 4 = 19 minutesTo find: Total time taken to run from mile marker 1 to mile marker 4.
Finding:
By basic algebra, we can say that:
The total time taken = Time taken to run from mile marker 1 to mile marker 2 + Time taken to run from mile marker 2 to mile marker 4
=> Total time taken = 8 minutes + 19 minutes = 27 minutes.

Find the point-slope equation for
the line that passes through the
points (-2, -20) and (9, 79). Use
the first point in your equation.
y - [?] = [](x-[])
The point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.
We are given the points as:
(- 2 , - 20) and ( 9 , 79)
We will first find the slope:
Slope = m = y₂ - y₁ / x₂ - x₁
m = 79 + 20 / 9 + 2
m = 99 / 11
m = 9
Now, we have to find the point-slope equation for the line that passes through the points (- 2, - 20) and (9, 79).
The point slope equation is:
y - [y₁] = [m](x-[x₁])
Substituting the values, we get that:
y + 20 = 9 ( x + 2 )
y + 20 = 9 x + 18
9 x - y + 18 - 20 = 0
9 x - y - 2 = 0
Therefore, the point slope equation for the line that passes through the points (-2, -20) and (9, 79) is 9 x - y - 2 = 0.
