Answer:

6.9%

Step-by-step explanation:

7 red marbles, 3 blue marbles and 8 green marbles = 18 marbles

P ( green ) = green/total = 8/18 = 4/9

Keep marble

7 red marbles, 3 blue marbles and 7 green marbles = 17 marbles

P ( green ) = green/total = 7/17

Keep marble

7 red marbles, 3 blue marbles and 6 green marbles = 16 marbles

P ( green ) = green/total = 6/16 = 3/8

P (green,green,green) = 4/9*7/17 * 3/8 = 7/102

To the nearest tenth of a percent

.068627451 = 6.8627451% = 6.9%

sp2606 [1]

Answer:

a)59.125, b)67.5, c)None

Step-by-step explanation:

Mean = All values added up and divided by the number of values
$\frac{24+95+76+60+15+48+80+75}{8}$

Median = Put all numbers in order from least to most and use the middle one, if there are two, use the mean of those two
$15, 24, 48, 60, 75, 76, 80, 95$ . The middle ones are 60 & 75 so $\frac{60+75}{2}$

Mode = The number that repeats more times. In this case none of them repeat.

PLEASE HELP ME I AM HORRIBLE AT TRIGONOMETRY!!! TRIANGLES ARE SO HARD!!!

OleMash [197]

Answer:

A construction worker may use trigonometry when building the roof of a house. They may have to calculate the right angle that hypotenuse must sit at so water doesn't build up on the roof and cause leaks.

(this may be more of an architect's job, as they are the ones that design the houses)

An air traffic controller may use trigonometry to find how long it will take an airplane to land/how far the airplane is from the ground while it is in the sky (hypotenuse), based on its height from the ground (opposite) and the distance away from the runway it is (adjacent). They can also calculate the angle of elevation of the airplane from the tower they work in.
