Answer: y = -3/2x + 3
Step-by-step explanation:
The slope is -3/2 (down 3, right 2)
The slope goes before x in graph functions so it’s -3/2x
The line goes through 3 on the y-axis (vertical line), so that’s where + 3 comes in.
y = -3/2x + 3
Answer:
20, 40, 60
Step-by-step explanation:
x + 2x + 3x = 120
6x = 120
x = 20
20, 40, 60
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 =
x = $3.00 per pound
Therefore, cost of 10 pounds blueberries = 3 × 10
= $30
160.67 = 2000*8*r
So 160.67 = 16000r
Then divide 16000 on both sides 160.67/16000 =r/16000
0.01=r
The problem is, I don't think that you estimated for letter a, so you can't do letter b.
