Solution :
Let :
X = number of overtime hours
S = total weekly salary
S = 
S = 480 + 18X
E(S) = 
= 750
Mean of S = 750
Var (S) = 
Var(S) = 
= 5184
Variance of S = 5184
The standard deviation equals square root of 5184 = 72
Answer:
15 degrees
X is an Acute Angle
Step-by-step explanation:
x+ 75 = 90
x =15
To round to the nearest ten, we will look at the number in the ones place, and determine if it is higher, lower, or equal to 5. In this case, 3 is less than 5, so we round down. This means that 483 rounded to the nearest ten is 480. :) I hope this helps you in the future! A common phrase you can think about is:
Four or less, give it a rest. 5 and above, give it a shove.
The correct answer is 9lbs!
You will start by subtracting the initial $2 which leaves you with $1 left. after that you count how many times $0.15 goes into your $1 left. That answer should be 6 time which is $0.90. Now you add the 6 to the original 3 to get 9lbs!
