Using the stem and leaf plot find the five number summary for the data by hand 1|78 2|147 3|14

5/12, or 5: 12

step-by-step explanation:

2

step-by-step explanation:

yx = 36

step-by-step explanation:

cos f = opposite side/ hypotenuse

cos f = yw / yx

we know cos f = 4/9 and yw =16

4/9 = 16/yx

multiply each side by yx

4/9 yx = 16/ yx * yx

4/9 yx = 16

multiply each side by 9/4

9/4 * 4/9 yx = 16 *9/4

yx = 36

to solve for a variable means to isolate the variable on one side of the equation.

note: we can write (1/2)(bh) as one fraction like this (bh/2). they mean the same thing.

we now have this:

a = (bh/2)

we multiply both sides of the fractional equation by 2. this is done to remove the fraction.

doing this we now have a linear equation:

2a = bh

we now divide both sides of the equation by h to find the value of b.

final answer:

(2a/h) = b
