Answer:

Ok,You need to put the value of x that appears in the table to give you the result of h (x)

1.h(x)=4x+5

h(-5)=4(-5)+5

h(-5)= -20+5

h(-5)= -15

2.h(-1)=4(-1)+5

  h(-1)= -4+5

  h(-1)= 1

3. h(1)=4(1)+5

   h(1)=4+5

   h(1)=9

4. h(3)=4(3)+5

   h(3)=12+5

   h(3)=17

5. h(4)=4(4)+5

    h(4)=16+5

    h(4)=21

Step-by-step explanation:

  x                  h(x)

-5                    -15

-1                       1

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

6. A landscaping company ordered 13 plants and 4 trees for a total of $487. If plants are $8 each write and solve a linear equat
Lady_Fox [76]

Answer:95.75

Step-by-step explanation:

13x + 4y = 487

13*8 + 4y = 487

4y = 487 - 13*8

y = (487 - 13*8)/4

y = dollars per tree = 95.75
