Answer:
The length of fencing will be 
Step-by-step explanation:
Step 1
Find the dimensions of the rectangle
we know that
The area of a rectangle is equal to
In this problem we have
so
-----> equation A
-----> equation B
Substitute equation B in equation A
square root both sides
Find the value of b
-----> 
step 2
Find the length of fencing
The perimeter of a rectangle is equal to
we have
substitute
Answer:
Step-by-step explanation:
Given that sample size is 130 >30. Also by central limit theorem, we know that mean (here proportion) of all means of different samples would tend to become normal with mean = average of all means(here proportions)
Hence we can assume normality assumptions here.
Proportion sample given = 92/130 = 0.7077
The mean proportion of different samples for large sample size will follow normal with mean = sample proportion and std error = square root of p(1-p)/n
Hence mean proportion p= 0.7077
q = 1-p =0.2923
Std error = 0.0399
For 95% confidence interval we find that z critical for 95% two tailed is 1,.96
Hence margin of error = + or - 1.96(std error)
= 0.0782
Confidence interval = (p-margin of error, p+margin of error)
= (0.7077-0.0782,0.7077+0.0782)
=(0.6295, 0.7859)
We are 95% confident that average of sample proportions of different samples would lie within these values in the interval for large sample sizes.
Answer:
the answer is 4
Step-by-step explanation:
8-4=4
Step-by-step explanation:
$13.50 per hour. 40 hours per week.
that makes her regular weekly income
40×13.5 = $540.00
in that particular week she had 8 his overtime in addition.
the overtime hourly rate is
13.5 × 1.5 = $20.25
so, she earned an additional
8×20.25 = $162.00
therefore she earned in that week in total
540 + 162 = $702.00
