A school has two varsity basketball teams. One is the girls' team, and the other is the boys' team. On any given Saturday in Dec

belka [17]

The probability that either the girls' or boys' team gets a game is 0.85

Step-by-step explanation:

Step 1:

Let P(G) represent the probability of girls team getting a game and P(B) represent the probability of the boys team getting a game.

P(B ∪ G) represents the probability of either girls and boys team getting a game.

P(B ∩ G) represents the probability of both girls and boys team getting a game.

Step 2:

It is given that P(G) = 0.8, P(B) = 0.7 and P(B ∩ G) = 0.65

We need to find the probability of either girls or boys team getting a game which is represented by P(B ∪ G)

Step 3:

P(B ∪ G) = P(B) + P(G) - P(B ∩ G)

= 0.8 + 0.7 - 0.65 = 0.85

Step 4:

Answer:

The probability that either the girls' or boys' team gets a game is 0.85

Use five different colors to paint the four rectangles A, B, C and D shown in the figure. No two rectangles sharing an edge can

GenaCL600 [577]

There are 120 ways to color the 4 rectangles

<h3>How to determine the number of ways?</h3>

The given parameters are:

Paints, n = 5

Rectangles, = 4

The number of ways to color the rectangles is

$Ways = ^nP_r$

This gives

$Ways = ^5P_4$

Apply the permutation formula

$Ways = \frac{5!}{1!}$

Evaluate the expression

Ways = 120

Hence, there are 120 ways to color the 4 rectangles

Change 93/1,000 to decimel

Sloan [31]

Hey there!

In order to convert a fraction into a decimal, simply divide the numerator by the denominator. The numerator is the top part of the fraction while the denominator is the bottom part of the fraction.

So, 93 ÷ 1000 = 0.093

Thus, the decimal form of $\frac{93}{1000}$ is 0.093.

A man commutes to work a distance of 4040 miles and returns on the same route at the end of the day. His average rate on the ret

Vladimir [108]

Answer:

$T(x) = \frac{80x+1000}{x^2+25x}$

$T(30) = \frac{3400}{1650} = 2.061$

Step-by-step explanation:

If the rate is x, then the rate of the return is x+25. In both trips, he has 40 miles to travel, therefore, it will take 40/x hours in the first trip and 40/x+25 for the return. As a consecuence

$T(x) = \frac{40}{x} + \frac{40}{x+25} = \frac{40 ( x+(x+25))}{x(x+25)} = \frac{80x+1000}{x^2+25x}$

Also,

$T(30) = \frac{80*30+1000}{30^2+25*30} = \frac{3400}{1650} = 2.061$

This means that if he starts at 30 miles per hour, it will take a bit more than 1 hour to be there: 1 hour and 20 minutes in the first trip, and a bit more than 40 minutes (40/55 hours) in the return.
