Suppose the time to complete a 200-meter backstroke swim for female competitive swimmers is normally distributed with a mean μ =
Natali [406]
Answer: The proportion that will qualify is 0.0314 or 3.14%.

First, we need to find the z-score of a time of 128 seconds. To do this, we find the difference of the mean and score and divide by the standard deviation.

(128 - 141) / 7 = -1.86

Now, use a standard normal distribution table to determine the percent below a z-score of -1.86. That value is 0.0314 or 3.14%.

A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per m
Rina8888 [55]

Answer:

Finance charge = $1500

Step-by-step explanation:

Cost price of  jukebox = $9400

Down payment made by a local diner = $1000

Balance amount to be paid = 9400 - 1000 = $8400

In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months

Total amount to be paid in 36 months = 275 × 36 = $9900

So extra payment done = Total balance amount - Amount paid in 36 installments

= 9900 - 8400

= $1500

Therefore, finance charge paid by the diner was $1500.

m is miles

0.16m + 64d (this is rate 1)
0.08m + 128d ( this is rate 2)

since you plan to rent for one day, input d as 1.

0.16m + 64(1)
0.08m + 128(1)
