Sample means show a large variation because the data set has a large range. When there is a large variation in the data set, the sample means also will have a large variation. Jennie included small values in her sample, while Charles included high values.
Let’s double the number so 1/8= 2/16
She can eat 6 slices in 1 hour and it takes her 160 minutes or 2 hours and 40 minutes to finish the entire pizza.
Hope this helps! :3
Answer:
A) The minimum required diameter of the brass shaft D₁ = 0.00176 m
B) The minimum required diameter of the aluminium shaft D₂ = 0.00142 m
Step-by-step explanation:
<u>Data:</u>
A compound shaft has two segments made of brass and aluminium
Allowable shear stress of Brass = 69 MPa.
allowable sheer stress of Aluminium = 86 MPa.
Torque TC = 23900 N-m
<u />
<u>Find</u>: Minimum required diameter of the brass D₁ and Auminium D₂
<u>Solution</u>: see attached picture for workings that shows the break down of the minimum diameter for each segment of the shaft.
Answer:
one solution
Step-by-step explanation:
X-9=0
Add 9 to each side
X-9+9=0+9
x = 9
There is one solution
