Step-by-step explanation:
<u>Taking the readings from the graph</u>
- <u>x .... y</u>
- 0 .... 2
- 2 .... 6
- 4 .... 10
- 6 .... 14
<u>Rate of change for the given line is:</u>
- (6 - 2)/2 = 4/2 = 2
- y- intercept is 2
<u>Equation for the line is:</u>
<u>For the point (40, 76) we can verify with the equation:</u>
The point (40, 76) is close the line but the line doesn't pass through it.
Answer:
The means are 3 and 20.
Step-by-step explanation:
A proportion is simply a statement that two ratios are equal. In problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. To find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
Consider given proportion
Here, 2 and 30 are the extremes and 3 and 20 are the means.
Answer:
534. 75
Step-by-step explanation:
let the income of kellys sister be x
kellys income=x+15% of x
=23x over 20
x+23x/20=999. 75
or, x=465
kellys income=23×465/20
=534. 75
The equation is 12x = 15,000 and the answer is x = 125. 125 is how many rides you use so 15,000 people get to ride.
