X is multiple of 9 as well as 12.
Thus, smallest value will be 36 ( 9 *4 = 36, 12 * 3 = 36)
3 and 12 are not the multiples of 9.
72 is a larger multiple than 36; thus, the correct answer is 36.
Answer: 0.9746
Step-by-step explanation:
Given : A normally distributed population has a mean of 250 pounds and a standard deviation of 10 pounds.
i.e. 
Sample size : n= 20
Let 
sample mean values.
Then, the probability that this sample will have a mean value between 245 and 255 be
Hence , the probability that this sample will have a mean value between 245 and 255 is 0.9746 .
Answer:
1. The rectangular prism is a right prism with rectangular bases (check the picture)
2. It has 8 vertices, so we are looking for 3d figures with 4 vertices.
3. A face can have at least 3 vertices, and the 4th must be outside of the plane determined by the first 3 vertices. This makes 4 vertices in total.
4. The 3d figure described in step 3 is a pyramid.
so the answer is prism
Step-by-step explanation:
X - 89 = 7
Difference is - and is means equal to therefore is x - 89 = 7
