Answer:
There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
Step-by-step explanation:
Given : Claim : The mean temperature of the refrigerators is different from 45 degrees
To Find :Assuming that a hypothesis test of the claim has been conducted and that the conclusion is to reject the null hypothesis, state the conclusion in nontechnical terms.
Solution:
Claim : The mean temperature of the refrigerators is different from 45 degrees
So, Null hypothesis :
Alternate hypothesis :
We are given that the conclusion is to reject the null hypothesis.
So, we can say that the claim is true that mean temperature is different from 45 degrees.
There is sufficient evidence to support the claim that the mean temperature is different from 45 degrees
Answer:
1296 in³
Step-by-step explanation:
The volume (V) of a pyramid is calculated as
V = Ah ( A is the area of the base and h the perpendicular height (
Here A = 18 × 18 = 324 and h = 12, thus
V = × 324 × 12 = 1296 in³
Answer:
its 140
Step-by-step explanation:
Draw a diagram (shown below) to illustrate the problem.
The rotational speed is
ω = (3 rev/min)*(1 min/60 s)*(2π rad/rev) = π/10 rad/s
The period is
T = 2π/ω = 20 s
The amplitude of the rotational motion is equal to the radius of 15 ft.
At t=0, the height of the tip of the blade is horizontal to the right, therefore its motion relative to the ground is given by
A plot of the motion is shown below.
Answer:
2 times 30.
