As of​ 2011, the following are the ages at which a​ country's presidents were inaugurated. Construct a grouped frequency distribution for the data. Use 41​ - 45 for the first class and use the same width for each subsequent class.

Age: 41-45, 46-50, 51-55, 56-60, 61-65, 66-70

What are all these ages frequency's?

two data sets with the same median will not have the same varaibility

step-by-step explanation:

isaiah walks 3 miles due north, turns and then 5 miles due east. how far is he from his starting point?

a^2 + b^2 = c^2

let c = distance from starting point.

(3)^2 + (5)^2 = c^2

9 + 25 = c^2

34 = c^2

sqrt{34} = sqrt{c^2}

sqrt{34} = c

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
