Answer:
Height of prism (H) = 2.5 cm
Step-by-step explanation:
Given:
Base of rectangle (b) = 4 cm
Length of rectangle (l) = 7 cm
Volume of prism = 35 cm³
Find:
Height of prism (H)
Computation:
Volume of prism = 1/2 × b × l × H
35 = 1/2 × 4 × 7 × H
35 = 14 × H
Height of prism (H) = 2.5 cm
The formula for the sum of the squares of the deviations is
SS = s² (N -1)
We are given
SS = 316
N = 9
Substituting
316 = s² (9 - 1)
Solving for s
s = 6.28
The standard deviation is 6.28
Answer:
y = -6x
Step-by-step explanation:
slope-intercept form: y = mx + b
slope↑ ↑y-intercept
parallel lines have the same slope, thus the slope is -6
substitute the y in (0, 0) and the slope of -6 into the equation y = mx + b:
=> y = -6x + 0
=> y = -6x
Answer:
9c because you don't know how much money Kelly actually spent so instead of doing 9 x the price of each box, you replace it with c, so it's 9c
