8-10=-2
-2+5=3
3+7=10
10-(-20)=-10
Final score is -10 points
We have the following expression
This is equivalent to
Since
we have that
Therefore, the answer is the second option from top to bottom.
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:
43.2 degrees
Step-by-step explanation:
1. First, find the total number of people who were surveyed.
165+135+60+130+10=500
2. Next, figure out how many the Marine Corps is out of those 500 people.
60/500= 0.12 =12%
3. Last, find out what degree the 12% would take up.
We know that a circle is 360 degrees. To find 12% of 360 degrees, you will do:
0.12*360=43.2
So, the answer is 43.2 degrees
D. 0.75 is the correct answer
explanation- 2 out of the 8 tiles are not blue A. so 6 out of 8 tiles would round equal 75% chance of not getting a blue A tile
