Answer:(A) 6/15 9/25
(B) yes they are proportional cause both there highest factors are 3
Step-by-step explanation: Because both there highest factors are 3
Answer:
y = x+7
Step-by-step explanation:
Assuming all of these numbers are ordered pairs (coordinates) when x is 1 y is 8, when x is 2 y is 9 and so on. If you notice y is going up by 1 every time so it follows that the starting point (y intercept) must be 7. Therefore, our equation will be y = x + 7.
Test it out:
Let x =2
y = 2 + 7 = 9 This matches our coordinate (2,9) so it's correct.
Let x =4
y = 4 + 7 = 11 This matches our coordinate (4,11) so it's correct.
Feel free to try out the rest of the coordinates, but usually 2 is enough to confirm that your equation is correct.
Answer: 
Step-by-step explanation:
Given : A random sample of 1000 registered voters in Flagstaff found 760 registered voters who support immigration reform.
sample size : n= 1000
sample proportion: 
Critical value for 95% confidence interval = 
Confidence interval :
Hence, the 95% confidence interval for the true percent of registered voters in Flagstaff who support immigration reform:
Answer:
68% or 17/25
Step-by-step explanation:
100% - 32% = 68%
You could convert this to a fraction as 68/100 then simplify down to 17/25.
Answer:
ft^2
Step-by-step explanation:
Here in this question, we have a farmer who wants to purchase the correct amount of paint, but needs to know the surface area of the barn. We now need to select the correct unit in which the farmer would have his surface area.
In other words, what the question is simply asking us is to select which of the given units would serve as the appropriate unit for the surface area of the barn.
Mathematically, when we talk about area, we are simply talking about multiplying the length of a side with the length of another side.
We know the barn is not a single shape but shaped in terms of different segments which have different area and can be added together to give the total surface area of the barn.
Now, like we said above, we are multiplying a length by the length of another side, no matter the type of shape we are considering.
What this means is that our power( index) won’t be more than 2 since we can only multiply two sides of a particular length at a time.
So the option that would give the correct answer would be the option which has its power raised to the power of two.
The only option that fits the criterion is the last option which is the ft^2 and this in fact is the correct answer
