Answer:
81 books
Step-by-step explanation:
Every 4 months, Eva reads 36 books.
You first need to find the number of books Eva can read in 1 month
By dividing the ratio by you find that Eva can read 9 books per month.
You then add 4 and 5 together to get 9 because Eva has already read for 4 months and is going to read another 5 months after joining the book club.
You use the monthly ratio and multiply it by for the grand total of 81 books for the nine months that Eva has read.
Answer:
$6.57
Step-by-step explanation:
Answer: The answer is 1,037. You did good with the first three steps but you need to do the same for the last step, because you have 21 you have to find how many times 3 goes into it, which would be 7, and that gives you your full answer of 1,037.
Quartile Q 1 = 110. We have to find how many of electricians have score 110 or less.
For Q 1 : 25 % of the scores are below this value. The area under the bell-shaped curve of the normal distribution is 0.25. And since we have 288 electricians that took a certification test:
0.25 * 288 = 72.
Answer: 72 electricians had a score of 110 and less.
You have to start with the left triangle and find the side lengths. Since it is a 45-45-90, both sides are the same. Rule for this is hyp= sqrt2 * leg
Since hyp = 6sqrt2, the leg is 6.
The leg is also the hypotenuse of the triangle on the right side.
x is the side across from the hypotenuse and it is the short leg so x = (1/2)6
x = 3
