Answer:
x=7
Step-by-step explanation:
x+4=4x-17
4=3x-17
21=3x
x=7
I think the answer is 2.5
The answer would be E because as you may know, 10 mm is equal to 1 cm. So, 230 mm³ is equal to 23 cm³.
Answer:
True
Step-by-step explanation:
Given that:
M = 27, sample of n = 36 scores, µ = 30 and σ = 18.
The z score is used in statistics to determine by how many standard deviations the raw score is above or below the mean. If the z score is positive, the raw score is greater than the mean and if the z score is negative the raw score is less than the mean. The z score is given as:

Given that M = 27, this means that x = 27. Therefore:

This sample mean corresponds to a z-score of z = –1.00.
52/2= 26
12/2= 6
26-6= 20
26+6= 32
20+32=52
Ans: 20 and 32
