Mark is going to an awards dinner and wants to dress appropriately. He has one blue dress shirt, one white dress shirt, one blac

dlinn [17]

Solution:

Outfit Shirt Slacks Tie

Outfit 1 Blue Black Red

Outfit 2 Blue Grey Red

Outfit 3 White Black Red

Outfit 4 White Grey Red

Outfit 5 Black Black Red

Outfit 6 Black Grey Red

We take the outfits 1, 2 , 5 and 6 as a subset of the sample space.

So these 1, 2, 5 and 6 consists either a blue shirt or a black shirt.

The subset consists of all the outfits that do not have a white shirt.

So the correct options are :

1. (Choice A)

The subset consists of all the outfits that do not have a white shirt.

2. (Choice C)

The subset consists of all the outfits that have a black shirt.

a street light is at the top of a 18 ft tall pole. a woman 6 ft tall walks away from the pole with a speed of 4 ft/sec along a s

shutvik [7]

The most appropriate choice for similarity of triangles will be given by -

Speed of tip of the shadow of woman = 6 ft/s

What are similar triangles?

Two triangles are said to be similar, if the corrosponding angles of the triangles are same and the corrosponding sides of the triangles are in the same ratio.

Here,

The diagram has been attached here

Let the distance of woman from the pole be x ft and the distance of tip of the shadow to the pole be y ft.

Height of street light = 18 ft

Height of woman = 6ft

The two triangles are similar [As height of woman is parallel to the height of pole]

$\frac{y - x}{6}=\frac{y}{18}\\18y - 18x = 6y\\18y - 6y = 18x\\12y = 18x\\y = \frac{18}{12}x\\y = \frac{3}{2}x\\$

To find the speed, we have to differentiate both sides with respect to time 't'

$\frac{dy}{dt} =\frac{3}{2}\frac{dx}{dt}\\\frac{dy}{dt}=\frac{3}{2} \times 4\\\frac{dy}{dt} = 6$

Speed of tip of her shadow = 6 ft

At a carnival game, you randomly throw two darts at the board and break two balloons. What is the probability that both the ball

Amanda [17]

4/15 of the balloons are purple. You have two darts. There are 105 combinations of hitting two balloons out of the 15. There are 6 combinations of purple balloons to be hit. This (Purple combinations over total combinations) is your probability. 6/105 simplified to 2/35 or 2:35
So your chance of picking the purple balloons, both purple, out is 2 in 35 or 2/35

Please help I will increase the amount of points for every question answered

Rasek [7]

Answer:

<em>Rate of Change = 4</em>

Step-by-step explanation:

The starting point (x=0) is (0, -2)

The ending point (x=2) is (2, 6)

The distance between the two points in rise over run terms is 8/2

$\frac{8}{2} =4=rate$
