Suppose Clay, a grocery store owner, is monitoring the rate at which customers enter his store. After watching customers enter f
Kitty [74]

Answer:

70th percentile for the amount of time between customers entering is 30.10

Step-by-step explanation:

given data

mean =  25

to find out

What is the 70th percentile for the amount of time between customers entering Clay's store

solution

we know that here mean is

mean = \frac{1}{\lambda}   ..................1

so here 25 =  \frac{1}{\lambda}

and we consider time value corresponding to 70th percentile = x

so we can say

P(X < x) = 1 - e^{- \lambda *x}      

P(X < x) = 70 %

1 - e^{\frac{-x}{25}}  = 70 %

1 - e^{\frac{-x}{25} }  = 0.70

e^{\frac{- x}{25} }  = 0.30

take ln both side

\frac{-x}{25} = ln 0.30

\frac{x}{25}  = 1.203973

x = 30.10

70th percentile for the amount of time between customers entering is 30.10

How do you write 11% as a decimal?​
n200080 [17]

Answer: 0.11

Step-by-step explanation: To write a percent as a decimal, first remember that a percent is a ratio that compares a number to 100.

So we can think of 11% as the ratio 11 to 100 or 11 divided by 100.

Dividing by 100 moves the decimal point 2 places to the left so 11 divided by 100 would move the decimal point 2 places to the left which would give us <em>.</em>11 or 0<em>.</em>11.

So 11% can be written as the decimal 0<em>.</em>11.
