We should follow the order of operations to solve this problem
7+18/(6-3)
First, we solve the problem in the parenthesis 6-3=3
7+18/3
Then we divide 18 by 3 which you get 6
7+6
Then you just add the remaining 7+6=13
Answer:
D -24/25
Step-by-step explanation:
sin(2x) = 2sin(x)cos(x)
cos(x) = ⅘
sin²(x) = 1 - cos²(x) = 1 - (⅘)²
sin²(x) = 9/25
sin(x) = -⅗
(Because 4th quadrant)
sin(2x) = 2(-⅗)(⅘)
= -24/25
Answer:
-3
Step-by-step explanation:

Answer:
According to one study, brain weights of men are normally distributed with a mean of 1.50 kg and a standard deviation of 0.14 kg.
For samples of 12 men, the possible sample mean brain weights have a normal distribution with a mean of 1.50 kg and a standard deviation of 0.0404 kg.
Problem: Determine the percentage of all samples of 12 men that have mean brain weights within 0.1 kg of the population mean brain weight of 1.50 kg. Interpret your answer in terms of sampling error.
