5 = 1/3
So divide each side by 5
we get
1 = 1 / 15
Each roll needs 1 / 15 cups of flour
First integer = x
Second integer = x + 2
Third integer = x + 4
Since four times the first integer equals six more than the product of two and the third integer.
=> 4x = 6 + 2(x + 4)
=> 4x = 6 + 2x + 8
=> 2x = 14
=> x = 7.
Hence,
First integer = x = 7
Second integer = x + 2 = 7 + 2 = 9
<span>Third integer = x + 4 = 7 + 4 = 11.</span>
Answer:
17% probability that a randomly selected student smokes.
Step-by-step explanation:
A probability is the number of desired outcomes divided by the number of total outcomes.
What is your estimate of the probability that a randomly selected student smokes?
This estiamte is the number of smoking students divided by the total number of students.
We have that:
There are 500 students.
85 smoke
So there is an 85/500 = 0.17 = 17% probability that a randomly selected student smokes.
