The equation 4 ( x - 2 ) = 100 is a true equation for a particular value of x. Explain why 2 ( x - 2 ) = 50 is also true for the
same value of x.
1 answer:
Answer:
a) 4(x - 2) = 100
4x - 8 = 100
4x = 92
x = 23
b) 2(x - 2) = 50
2x - 4 = 50
2x = 46
x = 23
Step-by-step explanation:
When solving for x in both equations, we get the same value of x which makes that statement true.

Given

This is a one-tailed test.


Since the p-value of the sample statistic (0.00383) is less that the significant level (0.025), we reject the null hypothesis.
84/2 = 42
42/2 = 21
21/3 = 7
7/7 = 1
84 = 2^2 * 3 * 7
