Answer: United States
Step-by-step explanation: Because threats the only independent variable the rest are dependent on others.
250 adults and 180 of which are parents, so 250 -180 = 70
are not parents.
<span>The results showed that 150 of the adults with children and
40 of those without thought the park should be expanded. So there are 180 – 150 = 30 parents who
answered no. and 70 – 40 = 30 not parents who answered no.</span>
<span>
yes | no
parents 150 | 30
not parents 40 | 30

<em><u>Answer:</u></em>
145.309
<em><u>Step-by-step explanation:</u></em>
So we want to find the midpoint of the two number: 145.809 and 144.809, what we want to do it to find the difference between the two numbers and then divide it by 2 so we can find the halfway point:
145.809 - 144.809 = 1
^ So from this, we just have to add half of 1 or 0.5 to the smaller number:
144.809 + 0.5 = 145.309
Step-by-step explanation:
y-intercept = 2
x-intercept= 2.5
Vertex= 1,4
y=mx+b
Answer:
1050 units
Explanations:
Given the equation y=500+0.2x to determine his weekly paycheck based on his sales volume, where:
y is the amount of his check
x is the number of units he sells each month.
In order to determine the amount of units he would need to sell for his paycheck to be $710, we willl substitute y = 710 into the equation and find the value of x as shown:
y=500+0.2x
710 = 500+0.2x
710-500 = 0.2x
210 = 0.2x
0.2x = 210
Divide both sides by 0.2
0.2x/0.2 = 210/0.2
x = 1050
Hence he would need 1,050 units to sell for his paycheck to be $710
