2 standard deviations contain 95% confidence. So thus you would have 4hrs in either direction. So the interval at which we could feel 95% confident is between 11-19hrs.
Answer:
$466.93
Step-by-step explanation:
I multiplied by 26.50 & 17.62 and that got me $466.93. Or you can divide that into 17.62 = $1.50
you would move the decimal to the right four times giving you 782000
Answer:
n+18=7(n-3)
Step-by-step explanation:
Lets replace "A number" with the variable n because we do not know its value!
1) Rewrite the problem as an equation
n+18=7(n-3)
<u>If we want to solve the equation, do the following:</u>
1) Distribute 7 to n and -3:
n+18=7n-21
2) Add 21 to both sides:
n+39=7n
3) Subtract n from both sides:
39=6n
4) Divide both sides by 6:
n=6.5
