Answer:
Equation 1: 50 + 5x = 80, Or 5(10 + x) = 80
Equation 1 answer: 6
Equation 2: 5x + 10 = 80
Equation 2 answer: 14
Hey there!
In order to find out which one is greater, lets convert both of them into percents.
To convert a decimal into a percent, simply multiply the decimal by 100 or move the decimal two places to the right.
So!
0.086 × 100 = 8.6%
Now, we know that 0.086 is equal to 8.6% So, the correct answer is 86%
86% is greater than 0.086.

Answer:
The probability that the average final exam grade of this sample is between 77 and 82
P(77≤ x⁻≤ 82 = 0.8315 or 83%
Step-by-step explanation:
<u><em>Step(i):</em></u>-
Given random sample size 'n' = 40
Mean of the normal distribution = 81
Standard deviation of normal distribution = 6.6
Let x₁⁻ = 77
Z₁ = -3.83
Let x₂⁻ = 77
Z₂ = 0.958
<em>The probability that the average final exam grade of this sample is between 77 and 82</em>
P(77≤ x≤ 82) = P( -3.83 ≤x≤0.958)
= A( 0.958) + A(3.83)
= 0.3315 + 0.4995
= 0.8315
<em>The probability that the average final exam grade of this sample is between 77 and 82 = 0.8315 or 83%</em>
