Suppose the linear regression line y = 3.125x – 23.115 predicts a lemonade stand's profits based on the number of cups sold. If x represents the number of cups sold, and y represents the lemonade stand's profits in dollars, about how much can the lemonade stand expect in profits if it sells 225 cups?

What is the circumference of a circle having a radius of 56 mm
Answers
Answer:
The circumference is 351.68 millimeters or 352 millimeters.
Step-by-step explanation:
The formula to find the circumference of circle is 2 * pi * radius.
Applying Circumference Formula: 2 * 3.14 * 56 = 351.68 millimeters.
If you need to round to the nearest hundredth, the answer would be
352 millimeters.

One train is traveling 120 m with a velocity of 52 km/h and a
second train is traveling in the opposite direction with a
velocity of 20 km/h. How long will it take for them to
completely pass one another?
Answers
Answer: It took the train 11 s to completely pass the other.
11 seconds it takes for them to completely pass one another if one train is travelling 120 m with a velocity of 52 km/h.
What is distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
We have:
One train is travelling 120 m with a velocity of 52 km/h.
A second train is travelling in the opposite direction with a velocity of 20 km/h.
Here, the length of the second train is not given:
We are assuming the length is 100 m
Relative velocity = 52+20 = 72 km/h = 20 meter/seconds
Total distance: = 120 + 100 = 220 m
The time = 220/20 = 11 seconds
Thus, 11 seconds it takes for them to completely pass one another if one train is travelling 120 m with a velocity of 52 km/h.

At the math store, one circle costs one amount, and each square costs another amount. 5 circles plus one square is 20 cents. How much would 12 circles plus 5 squares cost?
Answers
Answer: 61 cents
Step-by-step explanation:
Let’s assume a circle is X and a square is Y.
The problem states:
5x + 1y = 20
2x + 3y = 21
Taking the 1st equation we can see that
1y = 20-5x which is the same as
y = 20–5x
If we replace y in the 2nd equation with the above we get:
2x + 3(20–5x) = 21
which is the same as
2x + 60 - 15x = 21
we can rearrange to get
2x -15x = 21 -60
which is the same as:
-13x = -39
therefore x = -39/-13 or
x = 3
We can then calculate y
If y = 20–5x, then y = 20 -15
There y = 5
So to answer you question, 12 circles plus 5 squares =
12x + 5y = 12(3) + 5(5) = 36 + 25 = 61 cents

A set of data already has the values 11, 14, 23, and 16. What value would have to be added to the set for the mean of the
five numbers to be 18?
08
12
18
26
Answers
We have to go at this kind of backward.
We find the average by adding up the numbers, then dividing by how many numbers we have.
In this example, we will have 5 numbers...so
x divided by 5 = 18
x/5 = 18
x = 90
The sum of all 5 numbers is 90, so then subtract the 4 numbers you already know to find the one you’re missing. (We’ll call it n)
90 - 8 - 12 - 18 - 26 = n
90 - 64 = n
n = 26
