Answer:
0.000023456633455 is answer
One inequality will be about the number of hours Wyatt works, and the other about how much money he makes based on the number of hours he works at each job.
x represents dog walking, y represents tutoring
Hours inequality:
x + y ≤ 13
y ≤ -x + 13
Income inequality:
8x + 14y ≥ 140
14y ≥ -8x + 140
y ≥ -4/7x + 10
To determine the solution to these inequalities, we can set them equal to each other and solve for x, then use our value of x to solve for y.
-x + 13 = -4/7x + 10
-x +3 = -4/7x
3 = 3/7x
x = 7
y = -x + 13
y = -7 + 13
y = 6
The solution is (7, 6), where Wyatt works 7 hours walking dogs and 6 hours tutoring.
Assuming the 6 is the underlined digit, it is in the "hundred millions" place. Its place value there is 600,000,000. That's six hundred million.
If 7 is the underlined digit, it is in the "ten millions" place. Its place value there is 70,000,000. That's seventy million.
_____
The place value of a digit is revealed by setting all the other digits to zero.
Samples simply refer to a dataset that represents the overall population.
The term used to describe the type of survey is that, it is a <em>voluntary response sample</em>.
From the question, we understand that the survey question was posted online to internet users.
This means that:
- The respondents are not selected
- The respondents are not a population (<em>because not all internet user would respond)</em>
However, users that choose to respond do so at their own will (voluntarily).
Hence, the type of survey is <em>(a) a voluntary response sample</em>
