Answer:
6.0
Step-by-step explanation:
This involves using SOH CAH TOA.
we use Sin as we want to find x (which is side O, and we are given H).
So we get sin37 = O/H
= x/10
so x = 10 sin 37 = 6.018... = 6.0 to the nearest tenth.
Answer:
The 96% confidence interval for the population proportion of customers satisfied with their new computer is (0.77, 0.83).
Step-by-step explanation:
We have to calculate a 96% confidence interval for the proportion.
We consider the sample size to be the customers that responded the survey (n=800), as we can not assume the answer for the ones that did not answer.
The sample proportion is p=0.8.
The standard error of the proportion is:
The critical z-value for a 96% confidence interval is z=2.054.
The margin of error (MOE) can be calculated as:
Then, the lower and upper bounds of the confidence interval are:
The 96% confidence interval for the population proportion is (0.77, 0.83).

The percentage of trench coats sold increased by 23. 3%. therefore, option D is correct.
<h3>What is the percentage?</h3>
A percentage is a minimum number or ratio that is measured by a fraction of 100.
First, we need to subtract the final from the initial, then divide the difference by the initial, then multiply your answer by 100 to get the percentage
the final is 127, and the initial is 103
127 - 103 = 24
24/103 = 0.233
0.233 x 100
= 23.3%
Thus, The percentage of trench coats sold increased by 23. 3%.

Answer:
3/10 + 4/10
1/2 + 1/5
1/10 + 3/5
Step-by-step explanation:
3/10 + 4/10 = 7/10 (add numerator and keep denominator)
1/2 + 1/5 = 5/10 + 2/10 = 7/10 (use equivalent fractions)
1/10 + 3/5 = 1/10 + 6/10 = 7/10
