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, ![P(A|B)=\dfrac{P(A\bigcap B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%7CB%29%3D%5Cdfrac%7BP%28A%5Cbigcap%20B%29%7D%7BP%28B%29%7D)
So, we get,
![P(Non-fiction| 9th\ grade)=\dfrac{(Non-fiction\bigcap 9th\ grade)}{P(9th\ grade)}\\\\P(Non-fiction| 9th\ grade)=\dfrac{8}{43}\\\\P(Non-fiction| 9th\ grade)=0.19](https://tex.z-dn.net/?f=P%28Non-fiction%7C%209th%5C%20grade%29%3D%5Cdfrac%7B%28Non-fiction%5Cbigcap%209th%5C%20grade%29%7D%7BP%289th%5C%20grade%29%7D%5C%5C%5C%5CP%28Non-fiction%7C%209th%5C%20grade%29%3D%5Cdfrac%7B8%7D%7B43%7D%5C%5C%5C%5CP%28Non-fiction%7C%209th%5C%20grade%29%3D0.19)
<h3>Thus, the required probability is 0.19.</h3>
Answer:
10 ft above sea level
Step-by-step explanation:
20 below goes up by 30 then it would be -20 -10 0 10
Answer:
19 and 2
Step-by-step explanation:
Let x represent the first number and y represents second number
x + y = 19
x - y = 17 add two equations up
2x = 36 divide both sides by 2
x = 19 and since the difference is 17 the other number is 2
The mistake made by George is; D:George should have averaged the two differences instead of the two bounds.
<h3>How to Solve Successive Approximations?</h3>
In Mathematics, successive approximation can be defined as a classical method that is used in Calculus for solving integral equations or initial value problems.
In this question, George started the first iteration of successive approximation by using the lower and upper bounds of the graph. However, we can deduce that George made a mistake instep 5 because he should have used x = 3/2 as the new upper bound.
