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.

The unit rate of each of the brands are:
Brand A's unit rate = 37 cents per ounce.
Brand B's unit rate = 31 cents per ounce.
<h3>How to Find the Unit Rate?</h3>The unit rate of each brand is simply how much a brand of tomatoes will cost per ounce.
To find the unit rate of each brand, do the following:
Brand A's unit rate = 2.99/8 = $0.37 per ounce = 37 cents per ounce.
Brand B's unit rate = 4.99/16 = $0.31 per ounce = 31 cents per ounce.

The height or the distance between the two parallel sides of the given trapezium is 20 cm.
A trapezium or trapezoid is a two-dimensional geometric shape that has 4 sides, with one pair of parallel sides.
The parallel sides of a trapezium are called bases while the distance between them is the altitude or height.
The formula for the area of a trapezoid is given by
A = (a + b)/2 x h
where a and b are the parallel bases and h is the height.
Using this formula, the height or the distance between the two parallel sides can be computed.
A = (a + b)/2 x h
120 cm^2 = (5 cm + 7 cm) / 2 x h
120 = (12 / 2) x h
120 = 6h
h = 120 / 6
h = 20 cm
