gregori [183]

Answer:

0.9797

Step-by-step explanation:

We have X = number of insects in the 25bgrams of butter

Then the legal limit of concentration in peanut butter = 30 fragments/ 100 grams

Then insect amount in 25 grams =

E(X) = 30/100 x 25

= 0.3 x 25

= 7.5 fragments of insects

Using the poisson function in Excel, the probability of at least 3 crunchy critters

1 - p(X<=2)

p(X<=2) = POISSON (2, 7.5, TRUE) = 0.020156715

1 - 0.020156715

= 0.9797

Consider the following data set:

Komok [63]

Answer:

+5 Range; The range is now 25

Step-by-step explanation:

The original range would be calculated by subtracting 20 from 40, giving you 20 as the range. However, with the point 15 added, there would be a new lowest number, making the new range be 40-15, which is 25.

Jennifer is leasing a car from a local auto retailer. The terms of the lease include a 9% interest rate for 36 months with a res

katrin [286]

1. The problem gives the residual value in percentage, and you need it in dollars. So, if the MSRP for the car Jennifer is leasing is $ 17,500, you have:

57%/100=0.57

residual value=$17,500*0.57= $9,975

2. Then, you need to substract the residual value and the lease term, to calculate the value of the car, as below:

car value=$17,500-$9,975=$7,525

3. You need to calculate the money factor, which is the interest rate divided by 2400. Then, you have:

Interest rate=9%/100=0.09

Money factor=0.09x2400
Money factor=0.00375

4. The interest is:

I=($17,500+$9,975)(0.00375)
I=$103.03

5. Therefore, the monthly payment is:

Monthly payment=(car value/36 months)+Interest
Monthly payment=($7,525/36)+$103.03
Monthly payment=$209.02+$103.03
Monthly payment=$312.06

What will Jennifer’s monthly lease payment be?

The answer is: d. $312.06
