Answer:

First we need to know what's APR.

APR refers to a annual periodic rate that's charged in a credit card. It changes depending on the company. So, the daily periodic rate can be calculated by dividing the APR of the credit car by 360 or 365, depending on the credit card companies.

So, basically, you need to call the company and ask about the APR and ask if the use 360 or 365 days to calculate the daily periodic rate, then do the division.

Adrian and Brian are brothers. They leave the house on their bicycles and head to school that is a distance of 4 km away. Adrian

aleksley [76]

Answer:

Brian's rate is 15 km/hr

Adrian's rate is 16 km/hr

Step-by-step explanation:

Let r = Brian's rate

r + 1 = Adrian's rate

4/r = Brian's time

4/(r + 1) = Adrian's time

The difference in times is 1 min = 1/60 hr

$\frac{4}{r} - \frac{4}{r + 1} = \frac{1}{60}$ LCD = 60r(r + 1)

4(60)(r + 1) - 4(60)r = r(r + 1)

240r + 240 - 240r = $r^{2}$ + r

$r^{2}$ + r - 240 = 0

(r - 15)(r + 16) = 0

r = 15 or r = -16

Since the rate cannot be negative, Brian's rate is 15 km/hr and Adrian's rate is 16 km/hr

Question 10 of 10

Alika [10]

9514 1404 393

Answer:

D. y = -1/3x

Step-by-step explanation:

The line through the origin means the equation will be a proportion of the form y = kx. (You can also see this by looking at the answer choices.) The value of k is ...

k = y/x . . . . . divide the above equation by x

For the given point (x, y) = (-3, 1), the value of k can be seen to be ...

k = 1/-3 = -1/3

Then the equation for the line is ...

y = -1/3x . . . . matches D

When an opinion poll selects cell phone numbers at random to dial, the cell phone exchange is first selected and then random dig

Aliun [14]

Answer:

c. 8.25

Step-by-step explanation:

The given scenario corresponds to binomial experiment because

1. There are two possible outcomes i.e. each number can be working or not working.

2. On each dialing the probability of getting working cell number is p=0.55.

3. Cell phone numbers are randomly dialed so these are independent.

4. A pollster dialed 15 cell numbers i.e. n=15.

The mean number of calls that reach a working cell number can be calculated by computing mean of binomial distribution using the given information.

Mean of binomial distribution=E(x)=np

The mean number of calls that reach a working cell number=15*0.55=8.25

Thus, the mean number of calls that reach a working cell number=8.25
