Answer:
B) circumference = 15.7 inches
Step-by-step explanation:
5.0 inches is the diameter
Pi = 3.14 (this is a standard unit for solving circles)
the formula for circumference is:
circumference = diameter x Pi
circumference = 5 x 3.14 = 15.7 inches
Your answer would be 15.7

A camp program charges a registration fee and a daily amount.
The total bill for 12 days is $338. The total bill for 19 days is
$506. Slope can be represented by cost per day. Use x as the
number of days and y as the total cost to represent this
situation.
a. Find the slope for this situation. What does it represent?
b. Write a linear equation that models this situation.
Answers
Using the information given, it is found that:
a) The slope is of 24, which means that for each day, the total bill increases by $24.b) The linear equation is: [tex]y = 24x + 50[/tex]Linear functions:A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.Item a:
The total bill for 12 days is $338.The total bill for 19 days is $506.The slope is given by the change in y(total bill) divided by the change in x(number of days), hence:
[tex]m = \frac{506 - 338}{19 - 12} = 24[/tex]
The slope is of 24, which means that for each day, the total bill increases by $24.
Item b:
The total bill for 12 days is $338, hence, when [tex]x = 12, y = 338[/tex], and this is used to find b.[tex]y = 24x + b[/tex]
[tex]338 = 24(12) + b[/tex]
[tex]b = 50[/tex]
Hence, the linear equation is: [tex]y = 24x + 50[/tex]

Answers
Answer:
Nathan must order 21 sets of forks for the restaurant.
Step-by-step explanation:
Since Nathan needs to order some new supplies for the restaurant where he works, and the restaurant needs at least 571 forks since there are currently 361 forks, if each set on sale contains 10 forks, to determine the number of sets to buy you must perform the following calculation:
(571 - 361) / 10 = X
210/10 = X
21 = X
So Nathan must order 21 sets of forks for the restaurant.

what is the correct value of the coefficient of determination R² and give a correct interpretation of its meaning
Answer:
Interpretation of coefficient of determination R² = 0.3721
R² = 0.3721, meaning 37.21% of the total variation in test scores can be explained by the least square regression line
Step-by-step explanation:
Given the data in the question;
the least square regression line is;
y" = -1.5x + 85
the correlation coefficient r = -0.61
Now, the coefficient of determination R² is square of correlation coefficient r
R² = -61²
R² = 0.3721

A square has a perimeter of 12x^4 + 36x^3 inches. What is the length of each side?
Answers
Answer:
3x^4+9x^3
Step-by-step explanation:
Perimeter of a square is expressed as;
P = 4L
L is the length of each side
Given
P = 12x^4 + 36x^3
12x^4 + 36x^3 = 4L
4(3x^4+9x^3) = 4L
Divide both sides by 4
4(3x^4+9x^3)/4 = 4L/4
(3x^4+9x^3) = L
L = 3x^4+9x^3
Hence the length of each side is 3x^4+9x^3
