Ooh so the directions tell us what we need to find the entire line, which is made up of FH. so just add GH (15) and FG (6) together to find FH. so that is 21. FH=21.
Answer:
None of the expressions in the option is equal to 10 x(13).
Step-by-step explanation:
The answer can be verified by calculating the values of the expression in the question, those of each options, and then compare as follows:
Value of the expression = 10 x (13) = 10 x 13 = 130
Therefore, we have:
A. 10 + (1+3) = 10 + 4 = 14 
130
B. (10 x 1)+3 = 10 + 3 = 13 130
C. 10 + (1x3) = 10 + 3 = 13 130
D. (10 * 1)3 = 10 * 3 = 30 130
Based on the calculations above, none of the expressions in the option is equal to 10 x(13).
Commutative Property allows 5=b to be written as b=5!

<span>A medical researcher wants to investigate the amount of time it takes for patients' headache pain to be relieved after taking a new prescription painkiller. She plans to use statistical methods to estimate the mean of the population of relief times. She believes that the population is normally distributed with a standard deviation of 18 minutes. How large a sample should she take to estimate the mean time to within 4 minutes with 97% confidence?

n = [z*s/E]^2

n = [2.17*18/4]^2 = 96 when rounded up
