Answer:
Mean: 34.875, Median = 34.5, Mode = 34, Range = 6
360 / 3 = 120
120 hamburgers • 2 = 240 hotdogs
Answer:
a) Therefore 92.64% of customers receive the service for half-price.
b) Therefore it would take 8.52 minutes
Step-by-step explanation:
Given that ime required for an automotive center to complete an oil change service on an automobile approximately follows a normal distribution with:
mean (μ) = 15 minutes
Standard deviation (σ) = 3.5 minutes
a) The z score is given by the equation:

Since the service will take no longer than 20 minutes,

Using the probability table to get the probability of the z score
percent of customers receive the service for half-price = P(X < 20) = P(z < 1.43) = 0.9236 = 92.64%
Therefore 92.64% of customers receive the service for half-price.
b) Since the probability is 3% = 0.03, this corresponds with a z score of -1.88
Therefore:



Therefore it would take 8.52 minutes
360 - 2(65) = 230
A = C = 230/2 = 115
m<y = 360 - 115 = 245
answer: m<y = 245
Hi there!
![\large\boxed{y = \sqrt[5]{-(x-2)}}](https://tex.z-dn.net/?f=%5Clarge%5Cboxed%7By%20%3D%20%5Csqrt%5B5%5D%7B-%28x-2%29%7D%7D)

Rewrite h(x) as y:

Switch the x and y variables:

Isolate y by subtracting 2 from both sides:

Multiply both sides by -1:

Take the 5th root of both sides:
