Answer:
2 14/50 simplified to 2 8/25 (all I did was divide 14 and 15 by 2)
Step-by-step explanation:
To convert an improper fraction to a mixed fraction, divide the numerator by the denominator, write down the quotient as the whole number and the remainder as the numerator on top of the same denominator.

Answer:
![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Step-by-step explanation:
This is a question from conditional probability.
We are given:
![P(A \cap B) = \frac{3}{10}](https://tex.z-dn.net/?f=P%28A%20%5Ccap%20B%29%20%3D%20%5Cfrac%7B3%7D%7B10%7D)
![P(B)=\frac{2}{5}](https://tex.z-dn.net/?f=P%28B%29%3D%5Cfrac%7B2%7D%7B5%7D)
And, we need to find P(A | B)
According to the formula of conditional probability:
![P(A|B)=\frac{P(A \cap B)}{P(B)}](https://tex.z-dn.net/?f=P%28A%7CB%29%3D%5Cfrac%7BP%28A%20%5Ccap%20B%29%7D%7BP%28B%29%7D)
Using the values, we get:
![P(A|B)=\frac{\frac{3}{10} }{\frac{2}{5} }\\\\P(A|B)=\frac{3}{4}](https://tex.z-dn.net/?f=P%28A%7CB%29%3D%5Cfrac%7B%5Cfrac%7B3%7D%7B10%7D%20%7D%7B%5Cfrac%7B2%7D%7B5%7D%20%7D%5C%5C%5C%5CP%28A%7CB%29%3D%5Cfrac%7B3%7D%7B4%7D)
Thus, the probability of occurrence of event A given that event B has already occurred is ![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)

Answer:
Step-by-step explanation:
Given that in the weekly ad 5 pound bag of organic apples will cost 13.95 dollars
To find unit rate
Unit rate can be found in two ways either cost of 1 apple or no of apples for 1 dollars
I part:
5 apples = 13.95 dollars
1 apple = 13.95/5 (since direct variation)
Unit rate for one apple= 2.79 dollars
Part II:
13.95 dollars = 1 apple
1 dollar = 1/13.95 = 0.071
=0.07
But normally since apples are countable as 1,2 ... we use the first type of rate only unit rate per apple
