Nina: 4 leashes X 15 hours = 60 leashes
Bob:  3.5 leashes X 17.1428571428 hours = 60 leashes

Answer:

Number of leashes Bob can make in 2 hours = 7

Number of leashes Bob can make in 1 hour = 7÷2 = 3.5

Let, Bob takes total x hours.

Number of leashes Nina can make in 1 hour = 4

Let, Nina takes total x hours.

∴  The equation that can be used to find the number of hours it takes bob and Nina to make 60 leashes is given by-

3.5x+4x = 60.

7.5x = 60

This equation can be used to find the number of hours taken by Bob and Nina by putting different values of x and y which satisfies above equation.

The frequency distribution below represents the rents of 250 randomly selected federally subsidized apartments in Washington D.C
Naily [24]

Answer:

92%

Step-by-step explanation:

The percentage of apartments rented for less than $600 is given by the sum of all of the apartments in the 300 to 400, 400 to 500 and 500 to 600 intervals divided by the total number of apartments sampled (250).

P(X

92% of the apartments rented for less than $600.

____ [38]

Answer: <u>Last option</u>

Z_ {13} = 0.5,\ Z_ {17} = 2.5

Step-by-step explanation:

The z-scores give us information about how many standard deviations from the mean the data are. This difference can be negative, if the data are n deviations to the left of the mean, or it can be positive if the data are n deviations to the right of the mean.

To calculate the Z scores, we calculate the difference between the value of the data and the mean and then divide this difference by the standard deviation.

so  

Z = \frac{x- \mu}{\sigma}.

Where x is the value of the data, μ is the mean and σ is the standard deviation

In this case :

μ = 12 $/h

\sigma = 2 $/h

We need to calculate the Z-scores for x = 17 and x = 13

Then for x = 17:

Z_{17} = \frac{17-12}{2}.

Z_{17} = 2.5

Then for x = 13:

Z_{13} = \frac{13-12}{2}.

Z_{13} = 0.5

Therefore the answer is:

Z_ {13} = 0.5,\ Z_ {17} = 2.5

Komok [63]

Answer: Sienna’s loan is an example of closed-end credit

Step-by-step explanation: The main difference between closed-end credit and open-end credit is in the terms of the debt and its repayment.

Open-end credit are loans taken which are not restricted to a specific use or duration i.e the banks allows it's customers to take loans without a specific or set duration during which it most be paid back, the customer just have to promise that they will back back on time. Credit card accounts and debit cards are a good example of open-credit.

On the other hand, a close-end credit are loans taken by individuals or business for a particular period as specified, during which the individual or business is required to make regular payments. At the end of the set period the individual or business is required to pay back the entire loan, interest fee and maintenance fee. Mortgage and car loans are a good example of closed-end credit.

So Diego's statement is the correct statement; Sienna’s loan is an example of closed-end credit
