Answer:
34 square units
Step-by-step explanation:
The figure can be considered to be a trapezoid with a rectangle removed.
The area of the trapezoid is ...
A = (1/2)(b1 +b2)h
A = (1/2)(10 +6)(5) = 40
The area of the rectangle is ...
A = LW
A = (3)(2) = 6
Then the area of the shaded portion of the figure is ...
shaded area = trapezoid area - rectangle area
= 40 - 6 = 34 . . . square units
Answer:
R = 33.35%
Step-by-step explanation:
that is the solution above
That means one whole is cut into 8 parts, and one of those eight parts is considered to be one-eighth of a whole
{think about it like a pizza with 8 slices]
The answer is 2 because 4/1 - 83628 = four
Answer:
decrease
Step-by-step explanation:
Given that the sample statistics gathered would not change very much for the new sample
When it is decided to take a larger sample, we find that automatically the margin of error decreases and hence confidence interval will become narrower.
When confidence level decreases then critical value decreases and hence margin of error decreases thus resulting in to decrease the confidence level,
Hence width would decrease.
i) Because of a larger sample size
ii) BEcause of decrease in confidence level.
