Step-by-step explanation:
<u>Work:</u>
- 2(π x 21 x 21/2) + (π x 42 x 42/4) = Area of figure
- => π x 21 x 21 + (π x 42 x 42/4) = Area of figure
- => (22/7 x 21 x 21) + (22/7 x 21 x 21) = Area of figure
- => 2(22/7 x 21 x 21)
- => 2(22 x 3 x 21)
- => 2772 cm²
Hence, the area of the shape is 2772 cm².
So I drew a number line , & I placed point e at 1 1/4 . The correct answer will be B . It couldn't be A because if point e was 1/4 to the left of 1 , point e will be located at 3/4 . But because it ask to put point e at 1 1/4 , you would look for 1 & just move up 1/4 .
Answer:
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is 0.033 < p < 0.331.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of , and a confidence level of , we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of .
Only 2 of the 11 companies were planning to increase their workforce
This means that
80% confidence level
So , z is the value of Z that has a pvalue of , so .
The lower limit of this interval is:
The upper limit of this interval is:
An 80% confidence interval for the proportion of companies that are planning to increase their workforce is 0.033 < p < 0.331.
