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>
Hello there!
Your final answer would be
(<span>
(6x + 5) • (6x - 5)).Your correct answer would be
(option d).I hope this helps you!</span>
Step-by-step explanation:
The formula for finding the area of a trapezoid is
×h
Start by substituting the values given in the problem into the formula
×4
Now Simply/solve
×4
6×4
24
The area of the trapezoid is 24
I hope this helps!!!
Answer:
g(3) = 7
Step-by-step explanation:
g(3) means to substitute "x" for 3.
Change any "x" in the function to 3. Then solve.
Take the function
g(x) = 2x + 1
Substitute x = 3
g(3) = 2(3) + 1
Solve with BEDMAS order (brackets, exponents, division, multiplication, addition, subtraction).
g(3) = 2(3) + 1 Multiply first
g(3) = 6 + 1 Add
g(3) = 7 Answer
