Answer:
9.57 inch
Step-by-step explanation:
(4/3)×pi×8³ = 14×16×h
h = (4/3)×pi×8³ ÷ (14×16)
h = 64pi/21 inch
Or, 9.57 inch (3 sf)
Answer:
(x,-y): (2,-2)
Step-by-step explanation:
M=(x+x)/2,(y+y)/2
Given (1,4)=

This implies:


In a similar way,

The question demanded (x,-y)
Hence(2,-2) is the answer
Answer:
The correct option is (C) (2.769, 3.231).
Step-by-step explanation:
The confidence interval for mean when the standard deviation is not known is:

Given:

Compute the critical value as follows:

**Use a <em>t</em>-table.
The 95% confidence interval for true mean length of the bolt is:

Thus, the 95% confidence interval for true mean length of the bolt is (2.769, 3.231).
The correct option is (C).
