Answer:
(x+y) / 72
Step-by-step explanation:
Kate needs to read 2 books
she's not sure how many pages are in each book.
Let
Number of pages in the first book = x
Number of pages in the second book = y
Total pages of the two books = x + y
Kate's summer vacation = 72 days
she is planning to read the same number of pages each day of her summer vacation.
Number of pages she will need to read each day = (x+y) pages / 72 days
Number of pages she will need to read each day = (x+y) / 72
Answer:
70.06
Mean score = 70
Step-by-step explanation:
16% of students scored higher than 80 on a recent normally distributed exam the standard deviation is 10 what is the mean
For a normal distribution :
Zscore = (x - mean) / standard deviation
x = score
P(Z > 80) = 16% = 0.16 ; corresponding Zscore = 0.994 (Z probability calculator)
Therefore ;
0.994 = (80 - mean) / 10
0.994 * 10 = 80 - mean
9.94 = 80 - mean
Mean = 80 - 9.94
Mean = 70.06
Hence, the mean score = 70.06 = 70
Darryl’s credit card has a minimum monthly payment of 2.51% of the card’s balance.
Darryl currently owes $1,431.72. Let's solve his minimum payment.
=> 1,431.72 * 0.0251 = 35.94 dollars
=> 1,431.72 + 35.94 dollars = 1467.656172 or 1467.7 dollars.
here you go....
y=mx+b - slope intercept form
Slope = 1, y-intercept = 4
m is also the slope
b is the y-intercept
answer;
y=x+4
