Answer:
Step-by-step explanation:
By using regression line calculator,
Equation of the line of best fit,
c). y = 0.74x + 0.03
Here, x = Number of pints
y = Weight in pounds
d). We have to find the weight of 10 pints of the blueberries,
By substituting x = 10 in the equation,
y = 0.74(10) + 0.03
y = 7.4 + 0.03
y = 7.43 pounds
e). If per pound cost of the blueberries = $2.25
By substituting y = 2.25 in the equation,
2.25 = 0.74x + 0.03
x = ![\frac{2.22}{0.74}](https://tex.z-dn.net/?f=%5Cfrac%7B2.22%7D%7B0.74%7D)
x = $3.00 per pound
Therefore, cost of 10 pounds blueberries = 3 × 10
= $30

There is no way to solve for
, but we can simplify the expression.
![-2(n+2)-6n](https://tex.z-dn.net/?f=-2%28n%2B2%29-6n)
Distribute the
to the
.
![-2n-4-6n](https://tex.z-dn.net/?f=-2n-4-6n)
Combine the like terms.
![\boxed{-8n-4}](https://tex.z-dn.net/?f=%5Cboxed%7B-8n-4%7D)
We cannot simplify further, so this is the answer.
Answer: 144-4x=112 she missed 8 questions
Step-by-step explanation: Since there are 144 points in total and each question is worth four points you would subtract 4x with x being the number of questions missed from the total amount and set it equal to 112. Then you solve for x which gives you 8. Hope this helps. :)
G which would be the equal amount of gallons in each bottle would make the equation look something like g=10 gallons(divided by) 15 bottles so your answer would be B
Answer:
7/6
Step-by-step explanation:
in order for it to perpendicular then its need to be the negative reciprocal of it, so you flip the sign making it positive and do the opposite of the slope like for ex if it was 1/2 it would have been 2
