m<PQS = m<SQR

4y - 10 = 2y + 10

2y = 20

y = 10

m<PQR = m<PQS + m<SQR

= 4y - 10 + 2y + 10

= 6y

= 6•10

= 60

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

Solve by factoring g^2-14s+45=0

Andrej [43]

<h3>♫ - - - - - - - - - - - - - - - ~Hello There!~ - - - - - - - - - - - - - - - ♫</h3>

➷ First find two values that multiply to make 45 but add to make -14

As you will figure out through trial and error, it is -9 and -5

Factorize it with these values:

(g - 9)(g - 5)

The actual values for g would be the opposite of what is in the parenthesis

Therefore, g = 9, or g = 5

➶ Good Luck (:
