Eduardo opened a credit card at a department store with an APR of 22.29% compounded semiannually. What is the APY on this credit card? (2 points) a 44.58% b 11.15% c 23.53% d 49.55%​

Answers

Answer:

The correct option is c. 23.53%.

Step-by-step explanation:

The annual percentage yield (APY) can be calculated using the following formula:

APY = (1 + r / n)^n - 1 .............................. (1)

Where;

APY =  Annual percentage yield = ?

r = Annual percentage rate = 22.29%, or 0.2229

n = Number of compounding period per year = Semiannually = 2

Substituting the values into equation (1), we have:

APY = (1 + 0.2229 / 2)^2 - 1

APY = 0.2353211025, or 23.53211025%

Rounding to 2 decimal places, we have:

APY = 23.53%

Therefore, the correct option is c. 23.53%.

Grayson is playing a game in which the object is to obtain a 0 by adding the points scored during each round.

Round 1 Round 2 Round 3 Round 4 Round 5

-12

Based on the points he scored during the first 4 rounds, what score does Grayson need on the 5th round?

-24

-11

12

Answers

Answer:

0. See explanation below.

Step-by-step explanation:

Grayson is playing a game in which the objective is to obtain a zero, by adding together the points scored in each round.

For rounds 1 to 4,

4 + 7 + 1 + -12  =  12 - 12  = 0

The summation of points in the first four rounds already results to a zero.

Let us see if the addition of any of the three options for round 5 will still result in a zero!

0 + -24  =  -24

0 + -11    =  -11

0 +  12    =  12

So all the options here are wrong. The only option that would have been correct is 0.

Since   4 + 7 + 1 + -12 + 0  = 0

Maybe the complete question has 0 as the fourth option. Use that.

What is the mean, median, mode, and range of 10,14,15,15,16,22,22,22,24,24,27,31,32,37,40,44.

Answers

Answer:

mean 16.75

median 15.5

mode 13

range 16

Answer:

25.5 is the median, 22 is the mode, 24.7 is the mean and 34 is the range

Step-by-step explanation:

mean is the average, you get this by adding up all the numbers and then dividing the total by the amount of numbers there are.

the median is the number with the middle value, in this case there were 2 medians because the was an even number of numbers so you average the medians

mode is the number the occurs the most out of the whole set. For example in this case all the numbers occurred twice except 22 which occured 3 times

Last is the range which takes the highest number and subtracts it by the lowest number. It's just that simple!

A delivery company has 18 vehicles in its fleet.

Use this information to work out the total fuel bill for 1 working day.

You must show all your working.

Answers

Answer: £1517.04

Step-by-step explanation:

The fuel expenses for the vans will be calculated as:

Vans:

Since the average distance travelled per day is 198km and the average distance travelled per litre is 9km, the van would use:

= 198/9

= 22 litres

Since there are 8 vans, they'll use:

= 22 × 8 = 176 liters

Trucks:

Since the average distance travelled per day is 620km and the average distance travelled per litre is 6.2km, the truck would use:

= 620/6.2

= 100

Since there are 10 trucks, they'll use:

= 100 × 10 = 1000 liters

The amount of liters for both the van and the truck will be:

= 176 liters + 1000 liters

= 1176 liters

The fuel cost will then be:

= 1176 × 1£1.29

= £1517.04
