Answer: 9 times
Step-by-step explanation:
Let the total number students be x.
Then the number of students liked cookies and cream = 18% of x= 0.18 x
The number of strawberry = 2% of x = 0.02 x
Clearly, 0.18 x> 0.02 x
The number of times more students prefer cookies and cream than prefer strawberry =[tex]=\frac{0.18x}{0.02x}=9[/tex]
Hence, The students prefer 9 times cookies and cream than prefer strawberry.
A boat is traveling at a velocity represented by : 2x^3-10x^2+72x3−10x2+7. At the same time, current is pushing the boat in the same direction with a velocity given by : 5x^3+19x^2+4x5x3+19x2+4x. What is the total traveling velocity of the boat?
7x^3 +9x^2 +4x +7
Step-by-step explanation:The total velocity is represented by the sum of the two polynomials:
(2x^3-10x^2+7) + (5x^3+19x^2+4x) = x^3·(2+5) +x^2·(-10+19) +4x +7
... = 7x^3 +9x^2 +4x +7

Find the probability that your friend is at least 20 minutes late
If the graph has 1/3 length…
At least 20 minutes late: this would mean 20 minutes late or more.
20 or more minutes goes from 20 to 30. So that is a difference of 30 – 20 = 10. The distance of your rectangle is 10.
Length * width = (1/30) * 10 = 1/3 or 0.3333. The probability the friend is at least 20 minutes late is 0.3333.

Use the regression line for the data in the scatter plot to answer the question. On average, how many more goals will a player score for every additional hour of practice?
A. )1/2 of a goal
B. )3/4of a goal
C.) 1 goal
D.) 4/3 goals
Answer:
Step-by-step explanation:
Given is a scatter plot and the regression line using least squares.
We are required to find out how many more goals a player will score for every additional hour of practice.
In other words, we are to find the slope of the regression line.
By taking two points on the line we can find slope of the line.
(1.5,2) and (6.5,6) are points on the line
Find slope using two point formula
Slope = [tex]\frac{y2-y1}{x2-x1} =\frac{6-2}{6.5-1.5} \\=\frac{4}{5}[/tex]
near slope is 3/4
Hence answer is option b.
On average, the goals a player scores for every additional hour of practice will be 3/4.
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
We need to find out how many more goals a player will score for every additional hour of practice.
In other words, we have to find the slope of the regression line.
By taking two points on the line we can find the slope of the line.
Lets (1.5,2) and (6.5,6) are points on the line
So, the slope will be
Slope = y-y₁ / (x-x₁)
= 6- 2 / 6.5 - 1.5
= 4/5
Thus, the near slope is 3/4. Option B is correct.

Ray should consume 2,000 calories every day. He consumes 1,735 calories to get essential nutrients. What is Ray's discretionary calorie allowance? 115 calories 265 calories 1,735 calories 2,000 calories
Answer: 265 calories
Step-by-step explanation:
The discretionary calorie allowance is the balance of a person can take after achieving the number of calories need to get essential nutrients.
Given : Every day Energy allowance for Ray = 2,000 calories
Energy level required to get essential nutrients =1,735 calories
Then Ray's discretionary calorie allowance =
Energy allowance - Calories required to get essential nutrients
=2000-1735=265 calories
Hence, Ray's discretionary calorie allowance will be 265 calories.

What are the Quotients?Quotients are the number that is obtained by dividing one number by another number. We can use the fact that division can be taken as multiplication but with the denominator's multiplicative inverse.
Thus,
[tex]\dfrac{a}{\frac{b}{c}} = a \times \dfrac{1}{\frac{b}{c} } = a \times \dfrac{c}{b} = \dfrac{a \times c}{b}[/tex]
We have been given that [tex]-4 \dfrac{1}{2}[/tex] ÷ (-[tex]2 \dfrac{2}{3}[/tex])
But first convert the mixed fraction into simple fraction
[tex]-4 \dfrac{1}{2}[/tex] = -9/2
(-[tex]2 \dfrac{2}{3}[/tex]) = -8/3
Thus, we have to divide the terms;

-9/2 ÷ -8/3
-9/2 x -3/8

The temperature in mariah’s town was at 5.2 f midnight. the temperature decreased at a steady rate of 1.1 per hour until 7:00 a.m. at 7:00 a.m. the temperature increased by a total of 4.9until noon. what was the temperature at noon?
The temperature at noon was 2.4 degrees Fahrenheit.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions.
To determine the temperature at noon, we need to first calculate the temperature decrease between midnight and 7:00 a.m. and then add the temperature increase from 7:00 a.m. to noon.
The temperature decreased at a rate of 1.1 degrees Fahrenheit per hour, and it took 7 hours from midnight to 7:00 a.m., so the temperature decreased by a total of 7 hours x 1.1 degrees per hour = 7.7 degrees.
The temperature at 7:00 a.m. would therefore be 5.2 degrees - 7.7 degrees = -2.5 degrees Fahrenheit.
At noon, the temperature increased by a total of 4.9 degrees, so the temperature at noon would be -2.5 degrees + 4.9 degrees = 2.4 degrees Fahrenheit.
Thus, the temperature at noon was 2.4 degrees Fahrenheit.

Given the function h(x) = 4x, Section A is from x = 0 to x = 1 and Section B is from x = 2 to x = 3.
Part A: Find the average rate of change of each section. (4 points)
Part B: How many times greater is the average rate of change of Section B than Section A? Explain why one rate of change is greater than the other. (6 points)
Answer:
The rate of change of section A is 3 and rate of change of section B is 48.
Step-by-step explanation:
The given function is
[tex]h(x)=4^x[/tex]
Formula for average rate:
[tex]m=\frac{f(x_2)-f(x_1)}{x_2-x_1}[/tex]
Section A is from x = 0 to x = 1, the average rate of change of section A is
[tex]m_1=\frac{h(1)-h(0)}{1-0}=\frac{4-1}{1}=3[/tex]
Section B is from x = 2 to x = 3, the average rate of change of section B is
[tex]m_2=\frac{h(3)-h(2)}{3-2}=\frac{64-16}{1}=48[/tex]
Therefore rate of change of section A is 3 and rate of change of section B is 48.
[tex]m_1\times k=m_2[/tex]
[tex]3\times k=48[/tex]
[tex]k=12[/tex]
Therefore average rate of change of Section B is 12 times of Section A.
The given function is an exponential function and rate of change is not constant.

A farmer wants to fence a rectangular area by using the wall of a barn as one side of the rectangle and then enclosing the other three sides with 160 feet of fence. find the dimensions of the rectangle that give the maximum area inside.
Final answer:
To maximize the area with 160 feet of fencing and one side provided by a barn, the fencing should create a rectangle with equal width for the two sides perpendicular to the barn. By expressing length in terms of width and using calculus to find the maximum area, we find a width of 40 feet and a length of 80 feet maximizes the area.
Explanation:
The farmer is using the barn wall as one side of the rectangular area he wants to fence. The remaining three sides require 160 feet of fencing. To maximize the area of the rectangle with a given perimeter, the shape should be a square; however, since one side is already provided by the barn, the best we can achieve is to have the two sides perpendicular to the barn be equal in length.
Let's use width w to denote the length of the two sides that are perpendicular to the barn and length l to denote the side parallel to the barn but not including the barn's wall itself. The total amount of fencing the farmer has is 160 feet, which we can express using the equation:
2w + l = 160
Since we're optimizing for area A, and A = w x l, we want to find the values of w and l that give us the maximum A. We can express l in terms of w using the perimeter equation:
l = 160 - 2w
Substituting this into the area equation gives us:
A = w x (160 - 2w) = 160w - 2w²
To find the maximum area, we take the derivative of A with respect to w and set it to zero to find critical points.
dA/dw = 160 - 4w = 0
Solving for w gives us w = 40 feet. Therefore, the dimensions that give the maximum area when one side of a rectangle is fixed are a width of 40 feet and a length of 80 feet.
