You basically divide 171 by 3.
Answer:
An expanded form is to split a number and write in its thousands, hundreds, tens, and units form. The value of each digit in mathematics can be written in the expanded form. The first few non-negative powers of ten are: 1, 10, 100, 1,000, 10,000, 100,000, 1,000,000, and 10,000,000. PLS MARK BRAINLIEST!!

Answer:
10 problems
Step-by-step explanation:
This is the answer because:
1) We have to solve for what 20% of 50 is since she finished 20% of her test:
20% of 50 = 10
×
=
= 10
Therefore, the answer is 10 problems.
Hope this helps! :D
-6n -2n = 16
-8n = 16
n = 16/-8
n = -2
Answer: n = -2
Answer:
The answer is : 0.0597
Step-by-step explanation:
Population mean = μ = 80
Standard deviation = σ = 20
Sample = N = 60
σ_mean = σ/√N
= (20)/√(60) = 2.582
Now we will find z1 and z2.
z1 = {(84) - μ}/σ_mean = 
z2 = {(88) - μ}/σ_mean = 
Now probability that the sample mean will be between 84 and 88 is given by:
Prob{ (1.549) ≤ Z≤ (3.098) } = (0.9990) -(0.9393) = 0.0597
