Answer:

Least to greatest should be 1 over 6, 1 over 3, and then 2 over 5. least to greatest with the same denominator should be 5 over 30, 10 over 30, and 12 over 30

Step-by-step explanation:

First step is to find the common denominator, which is 30. Then you want to figure out how you got to 30 and multiply that by nominator. after you have that all complete, then just sort from least to greatest. To listed from least to greatest is you take the smallest number, for example which would be 5 over 30 and then sorts continuously from the greater number as well, which would be 12 over 30

The time required for an automotive center to complete an oil change service on an automobile approximately follows a normal​ di
xxMikexx [17]

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:

z=\frac{x-\mu}{\sigma}

Since the service will take no longer than 20 minutes,

z=\frac{x-\mu}{\sigma}=\frac{20-15}{3.5} = 1.43

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:

z=\frac{x-\mu}{\sigma}=\frac{x-15}{3.5} =-1.88

\frac{x-15}{3.5} =-1.88

{x-15} =-6.58\\x=-6.58+15=8.52\\x=8.52 minutes

Therefore it would take 8.52 minutes

Find the inverse of h(x)= -x^5+2 step by step
nikdorinn [45]

Hi there!

\large\boxed{y = \sqrt[5]{-(x-2)}}

h(x) = -x^{5} + 2

Rewrite h(x) as y:

y = -x^5 + 2

Switch the x and y variables:

x = -y^{5} + 2

Isolate y by subtracting 2 from both sides:

x - 2 = -y^5

Multiply both sides by -1:

-(x-2) = y^5

Take the 5th root of both sides:

y = \sqrt[5]{-(x-2)}
