Steps to solve
1) We have 5 +(-8)n = 29, which we can change to 5 - 8n = 29, because a positive times negative equals a negative
2) To isolate n, we move all of the other numbers to the other side of the equation. Since 5 is the only number on the left side, we subtract 5 from both sides
5 -5 - 8n = 29 -5
-8n = 24
3) Now, to find n, we want to just have one n on the left side instead of -8, so we divide the equation by -8 to find that
-8n/-8 = 24/8
n = 3
Therefore, n = 3

Answer:
Step-by-step explanation:
Given that a survey found that women's heights are normally distributed with mean 63.4 in and standard deviation 2.2 in.
Let X be the random variable representing women heights.
P(58<X<80)
Z for 58 = -2.454
Z for 80 = 7.545
P(-2.454<Z<7.545) = 0.4945+0.5=0.9945
Answer:
Step-by-step explanation:
<u>Two-digit numbers are:</u>
<u>Sum of them is:</u>
- 10a + b + 10a + c + 10b + a + 10b + c + 10c + a + 10c + b = 528
- 22a + 22b + 22c = 528
- a + b + c = 528/22
- a + b + c = 24
The only option of three different digits with the sum of 24 is 7, 8 and 9
