5/10 or 1/2 , both answers work
Answer:
Each additional cup is 1 centimeter.
Step-by-step explanation:
We know this because we can see the height on the graph. For each number of cups increased (y-axis), 1 centimeter in height increases as well.
Therefore, we can say that each additional cup is 1 centimeter.
Find slope first
Two points: (-5,-2) and (5,4)
(4+2)/(5+5) = 6/10 = 3/5 slope
So far: y = 3/5x + b
Plug in any of the point
-2 = 3/5(-5) + b, b = 1
Final equation: y = 3/5x + 1
Answer:
The data does not provide sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds.
Do not reject the null hypothesis because the p-value 0.0401 is greater than the significance level.
Step-by-step explanation:
Null hypothesis (H0): mu = 8.2 seconds
Alternate hypothesis (Ha): mu < 8.2 seconds
Significance level = 0.04
p-value = 0.0401
Using the p-value approach for testing hypothesis, do not reject H0 because the p-value 0.0401 is greater than the significance level 0.04.
There is not sufficient evidence to conclude that Kenneth's mean stacking time is less than 8.2 seconds.
Step-by-step explanation:
<h2>(3x + 8) (x + 2)</h2>
= 3x(x + 2) + 8(x + 2)
= 3x^2 + 6x + 8x + 16
= 3x^2 + 14x + 16
