2. There are 14 rollercoasters at the amusement park. There are 2 rollercoasters made of steel, 6 of them are made of steel and have loops, 4 of them have loops but aren't made of steel and there are 2 rollercoasters with no loops and aren't made of steel.
4. 60% of rollercoasters with loops are made of steel. 40% of rollercoaster with loops are not made of steel. 50% of rollercoasters made of steel have no loops and 50% of rollercoasters not made of steel don't have loops.
6. 75% of rollercoasters are made of steel either have loops or no loops.
25% of rollercoasters not made of steel either have loops or no loops.
This was quite a lot to do, I'm pretty sure the relative frequency graph number 3 had me a bit confused.
Answer:
66.6 or about 67 is the average rate of change

Explanation
The income is $42,000
6% 0f $42,000 = 6/100 ×42,000
= 0.06×42,000
= $2,520
This is more than your medical expense. This means that the portion that your medical expense that you can deduct is the whole amount, $567.
So if it is a parallelogram then the angles will add up to 360° and the angles opposite one another will be equal
we can start by finding y
3y = 42
divide by 3
y = 14
now we know that both angles are equal to 42° so to find the missing angles we must double 42 and subtract is from 360 then divide by 2 to find the individual angle
42 x 2 = 84
360 - 84= 276
276/2 = 138
the angle of 8x - 6 = 138
now we solve for x by first adding 6
8x = 144
then divide by 8
x = 18
so y = 14 and x = 18
