Answer:

Okay so if your current scores are 93, 97, 89 and 81, You would have to score at least a 90. Even if you scored a 100%, the highest you would be able to make is a 92 average.

Step-by-step explanation:

Here's the thing about average, all you do is take all of the numbers, add them up, then divide them by the number of numbers there are.

For example, 93 + 97 + 89 + 81 = 360. There are 4 numbers so you would take 360 and divide it by 4 which gets you 90. 90 is your average.

To figure out the highest score you are able to get, take the highest score you can possibly score (100) and add it to the mix. 93 + 97 + 89 + 81 + 100 = 460. Now, there are 5 numbers. So you take 460 and divide it by 5 which will get you 92.

Hope I helped.

Find the limit. use l'hospital's rule if appropriate. if there is a more elementary method, consider using it. lim x→4 x2 − 16 x

ivolga24 [154]

Probably you are supposed to compute

$\displaystyle\lim_{x\to4}\frac{x^2-16}{x^2-4x}$

Factorize the numerator and denominator, then simplify:

$\displaystyle\lim_{x\to4}\frac{(x-4)(x+4)}{x(x-4)}=\lim_{x\to4}\frac{x+4}x=\frac{4+4}4=2$

These dot plots show the ages in years for sample of sea turtles and sample of koi fish

sineoko [7]

Answer:

B. Centers: the sea turtles have a greater median age than the koi

D. Spreads: the ages of the koi are more spread out

Step-by-step explanation:

The difference between the center and spread of the data distribution of koi and sea turtles as shown in the dot plots are as follows:

==>Median:

For Koi, the median value is the 14th value represented by the 14th dot on the plot, which is 30.

The median value for koi is between the 7th and the 8th value represented by dots on the plot. The average of both values will give us 55 as the median value for koi.

Therefore, the median age of sea turtle is greater than that of koi.

==>Spread:

Koi has a range of 45 (60-15), while sea turtles have a range of 20 (65-45). Invariably, mere looking at the dot plot, we can conclude that ages of the koi are more spread out.

With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment

oksano4ka [1.4K]

Here is the complete question.

With a beginning balance of $1200 and no additional charges during the next three months, you will just pay the minimum payment each month for the next three months. The APR is 24.99% and the minimum payment each month is 3% of the balance. Determine the finance charge, new balance, and minimum payment required for each of the next three months, and the starting balance for month 4 in the table below.

a) What is the total of minimum payments?

b) What is the total sum of the finance charges?

c) How much does the starting balance decrease after these three payments?

d)The total of your finance charges is what percent of our total payments?

Answer:

Step-by-step explanation:

Month Beginning Finance New Minimum

Balance Charge Balance Payment

1 $ 1200 24.99 1224.99 36.75

2 1188.24 24.75 1212.99 36.39

3 1176.60 24.50 1201.10 36.03

4 1165.07 24.26 1189.33 35.68

The total minimum payments for 3 months = 36.75 + 36.39 + 36.03

The total minimum payments for 3 months = $ 109.17

Total finance charges for 3 months = 24.99 + 24.75 + 24.50

Total finance charges for 3 months = $ 74.24

c. The starting balance decrease from 1200 to 1165.07, this implies that there is a reduction of $ 34.93

d. The total of finance charges = 74.24×(100/109.17)

The total of finance charges = 68% of total payments.
