Answer:
0.5714 is the probability that a randomly selected customer will wait between 1 and 5 minutes at the delicatessen.
Step-by-step explanation:
We are given the following information in the question:
a = 0, b = 7
Then, the uniform distribution function is given by:
a) P( 1 < x < 5)
![=\displaystyle\int_{1}^{5} f(x) dx\\\\=\displaystyle\int_{1}^{5} \frac{1}{7}dx\\\\=\frac{1}{7}[x]_{1}^{5} = \frac{1}{7}(5-1) = 0.5714](https://tex.z-dn.net/?f=%3D%5Cdisplaystyle%5Cint_%7B1%7D%5E%7B5%7D%20f%28x%29%20dx%5C%5C%5C%5C%3D%5Cdisplaystyle%5Cint_%7B1%7D%5E%7B5%7D%20%5Cfrac%7B1%7D%7B7%7Ddx%5C%5C%5C%5C%3D%5Cfrac%7B1%7D%7B7%7D%5Bx%5D_%7B1%7D%5E%7B5%7D%20%3D%20%5Cfrac%7B1%7D%7B7%7D%285-1%29%20%3D%200.5714)
0.5714 is the probability that a randomly selected customer will wait between 1 and 5 minutes at the delicatessen.
She saves 480
1 Movie =$5
4. = x
$ 20 per week
4 weeks a month 4*20
=$80 dollars spent a month
12 months a year -12*80=960
______________
1 movie =5 dollars
2=x
X=10 $ spent per week
4 weeks a month =4*10
40*12
480 spent per year
960-480 =480 dollars saved
Step-by-step explanation:
if you call this limit to f(x), by the definition of derivatives f(x)=h'(x) such that
![h(x) = x + \frac{1}{ {x}^{2} }](https://tex.z-dn.net/?f=h%28x%29%20%3D%20x%20%2B%20%20%5Cfrac%7B1%7D%7B%20%7Bx%7D%5E%7B2%7D%20%20%7D%20)
then f'(x)=h''(x) then
![= 1 + ( - 2) {x}^{ - 3} = 1 - \frac{2}{ {x}^{3} }](https://tex.z-dn.net/?f=%20%3D%201%20%2B%20%28%20-%202%29%20%20%7Bx%7D%5E%7B%20-%203%7D%20%20%3D%201%20-%20%20%5Cfrac%7B2%7D%7B%20%7Bx%7D%5E%7B3%7D%20%7D%20)

Hello!
8 1/2 = 8.5 as a decimal
Multiply the number of friends Kellie called (6) by how long each call lasted (8.5 minutes):
8.5 * 6 = 51
