Answer:
m = ( y-c)/x
Step-by-step explanation:
y = mx+c
Subtract c from each side
y-c = mx+c-c
y-c = mx
Divide each side by x
(y-c)/x = mx/x
(y-x)/x = m
The distribution of the number of occurrences of the letter t on the pages of a book is found to be a normal distribution with a mean of 44 and a standard deviation of 18. If there are 500 pages in the book, which sentence most closely summarizes the data?
A. The letter t occurs less than 26 times on approximately 170 of these pages.
B. The letter t occurs less than 26 times on approximately 15 of these pages.
C. The letter t occurs more than 26 times on approximately 420 of these pages.
D. The letter t occurs more than 26 times on approximately 80 of these pages.
.Answer:
<span>mean = 44 </span>
<span>sd = 18 </span>
<span>that means that "26" is 1 s.d. down, or at the 16th %ile </span>
<span>so, there is a .16 chance that "t" will occur less than 26 times on any single page. </span>
<span>consequently, there is a .84 chance that it will occur more than 26 times on any single page. </span>
<span>Using that information, and knowing that 16% of 500 is 80, and 84% of 500 is 420, can you see where "C" is correct? </span>
He writes a check so he takes out the money so 2340 - 140 and then he deposits so because 2340 - 140 = 2,200 so, when he deposits 2200 + 268 then it will be the answer $2468.
$2468

Answer:
8 miles
Step-by-step explanation:
Given: A runner can run 5 miles in 26 minutes, 41.6 minutes = ___
To find: At this rate, how many miles can he run and 41.6 minutes?
Solution: If the runner ran 5 miles in 26 minutes, to find how far he ran in 41.6 minutes, set up a fraction:
let x be the variable
Apply fraction cross multiply;
Divide both sides by 26
Simplify
Then, at the rate, the runner ran 8 miles 41.6 minutes
