Answer: 45
Step-by-step explanation:
In 2016, 1 out of every 5 people under the age of 50 used a cell phone to read e-books. This means that 2 out of every 10 people under the age of 50 used a cell phone to read e-books. Also, 3 out of every 15 people under the age of 50 used a cell phone to read e-books.
Therefore, if there were x people under the age of 50 in 2016, then the number that used a cell phone to read e-books would be
1/5 × x = x/5
If there were approximately 225 million people under the age of 50 in 2016, then the number that were likely to have read an e-book on a cell phone is
225/5 = 45 people.
First we have to find p(AnB)
P(A/B)=p(AnB)/p(A)
P(AnB)=p(A) x p(A/B)
P(AnB)=0.5 x 0.4 = 0.2
Then to find p(B)
P(A∪B) = P(A) + P(B) - P(A∩B)
P(A∪B) = 0.5+p(B)-0.2
0.6=0.3+p(B)
P(B)=0.6-0.3=0.3
My teachers desk would fit about 6 1/2
The relationship being proportional means there is a value of k such that
... y = k·x
We are given the point (6 (pounds), 3 (dollars)), so we can write ...
... 3 dollars = k·6 pounds
Dividing by 6 pounds, we get
... (3/6) dollars/pound = k = $0.50/lb
Now, we can use x=1 pound to find the price (y),
... y = ($0.50/lb)·(1 lb)
... y = $0.50 . . . . the price of 1 pound of tomatoes.
