From what we know, p is 20 more than q. So, we can assume p = 20 + q. Q can also be found by subtracting 20 from both sides. So, q = p - 20.

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>
Answer:
Sally has 1,532 stickers remaining.
Step-by-step explanation:
First, you have to determine the total amount of stickers Sally bought by multiplying the number of sheets she bought for the number of stickers in each sheet:
124*14=1,736
Now, you have to subtract the number of stickers Sally gave away to her family and friends from the total amount of stickers she bought:
1,736-204=1,532
According to this, the answer is that Sally has 1,532 stickers remaining.
Answer:
x² - 12x + 27
Step-by-step explanation:
(f + g)(x)
= f(x) + g(x)
= x² - 13x + 36 + x - 9 ← collect like terms
= x² - 12x + 27 ← in standard form
I think the first one is correct.
