Rectangle does not have equal sides
It looks like the first thing you have to find is their GCF, ya reckon ?
The factors of 56 are 1, 2, 4, 7, 8, 13, 28, and 56 .
The factors of 64 are 1, 2, 4, 8, 16, 32, and 64 .
The common factors are 1, 2, 4, and 8 .
The greatest one is 8 .
56/8 = 7
64/8 = 8
56 plus 64 = (8 times 7) plus (8 times 8)
<span>56 plus 64 = </span><u>8 times (7 plus 8)</u><span> <== that's the answer</span>
Check it out:
<span>56 plus 64 = </span><u>120</u>
<span>8 times (7 plus 8) = 8 times 15 = </span><u>120</u><span> </span>
Answer:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
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 .
For this problem, we have that:
99% 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:
The 99% confidence interval for the proportion of the population who are obese is (0.25, 0.282)
Answer:
Step-by-step explanation:
The variable w is equivalent to y, and the variable z is equivalent to x.
