Answer:
w=4
Step-by-step explanation:
2(48)+2(8w)+2(6w)=208
1) Start by Distributing the value outside of the parenthesis:
96+16w+12w=208
2) Combine alike terms:
96+28w=208
3) Subtract 96 from both sides:
28w=112
4)Divide both sides by 28 to isolate w:
w=4

Answer:
Approximately 68% of daily phone calls will be in this interval.
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
In this problem, we have that:
Mean = 57
Standard deviation = 7
What is the approximate percentage of daily phone calls numbering between 50 and 64
50 = 57 - 7
So 50 is one standard deviation below the mean
64 = 57 + 7
So 64 is one standard deviation above the mean
By the Empirical Rule, approximately 68% of daily phone calls will be in this interval.
Write 2/625 and then multiply the result by 100%: 200%/625 can be re-written as 8% / 25 by dividing both 200 and 625 by 25.
8% / 25 can be thought of as "eight twenty-fifths of 1 percent. (ANSWER)
Using my calculator, I found that 2/625 is 0.0032. Mult. that by 100% results in 0.32. Note that 8/25 = 0.32.
Answer:
it would be (38x+15)+38y
Step-by-step explanation:
x=number of weeks
38 times x=38x
53x=53 weeks
bonus of 15=38x+15
