If 8=8 it will be 8(7) which means we have to do 8*7 and 8*7 will be 56 so the answer is 56 :) brainliest would be appreciated
That would be choice 2. One acute angle is the complement of the other
eg in a 90-60-30 triangle sine 30 = cos 60
Answer:
The answer in 180000 * 3 ÷ 100 = 5400$
Answer:
The margin of error for the 90% confidence interval is of 0.038.
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
.
The margin of error is:

To this end we have obtained a random sample of 400 fruit flies. We find that 280 of the flies in the sample possess the gene.
This means that 
90% confidence level
So
, z is the value of Z that has a pvalue of
, so
.
Give the margin of error for the 90% confidence interval.



The margin of error for the 90% confidence interval is of 0.038.
-3(x+3)=-3(x+1)-5
-3x-9=-3x-3-5
-3x-9=-3x-8
