Let one no. be x , Then according to question other number will be 8x
Now 8x - x = 70
7x = 70
x=10
hence one no is 10 and other 80
Answer:
The sample proportion denoted 
, is given by the formula 
, where x is the number of individuals with a specified characteristic in a sample of n individuals.
When we want to estimate the real population proportion 
we use as estimate the sample proportion, given by 
. Where:
x is the number of individuals with a specified characteristic in a sample
n represent the sample size of individuals selected.
Step-by-step explanation:
For this case we can complete the phrase like this:
The sample proportion denoted , is given by the formula , where x is the number of individuals with a specified characteristic in a sample of n individuals.
When we want to estimate the real population proportion we use as estimate the sample proportion, given by . Where:
x is the number of individuals with a specified characteristic in a sample
n represent the sample size of individuals selected.
The correct expression for hats with Ms. Ibarra is a = 7b - 15 where "a" represents number of hats with Ms. Ibarra and "b" represents number of hats with Ms.boyle
<h3><u>Solution:</u></h3>
Given that Ms. Ibarra has 15 less hats than 7 times Ms. boyle
To find: correct expression for Ms. Ibarra
Let the number of hats with Ms. Ibarra be "a"
Let the number of hats with Ms.boyle be "b"
Ms. Ibarra has 15 less hats than 7 times Ms. boyle Which means,
Number of hats with Ms. Ibarra = 7(number of hats with Ms.boyle) - 15
a = 7(b) - 15
a = 7b - 15
So the correct expression for hats with Ms. Ibarra is a = 7b - 15

The solution is (1,0)
Explanation:
The two equations are 
and 
We need to solve the equation using elimination method.
Adding the two equations, we get,
Thus, the value of x is 1
Substituting in the equation , we get,
Simplifying, we get,
Thus, the value of y is 0.
The solution is (1,0)
