Hypotenuse therom ( a^2 + b^2 = c^2)
1) find c^2
22^2 + 16.1^2= c^2 ———->743.21
2) square root c^2 to find c
square root of 743.21 = 27.2 so D
Answer:
c. 6√2

Answer:

Step-by-step explanation:
We are given: 
So, the integral will be used to calculate the volume.

Answer:
Required probability is 0.19
Step-by-step explanation:
The two-way table for the given data is,
Fiction Non-Fiction Total
9th grade 35 8 43
10th grade 52 12 64
Total 87 20 107
It is required to find the probability of the students who prefer to read non-fiction novels, given that they are in 9th grade.
That is, to find the conditional probability
.
Now, 
So, we get,

<h3>Thus, the required probability is 0.19.</h3>
