50 ≥ 8 + 15 + 0.9x

You can spend less than 50 or 50 dollars. x represents the number of games she can play. The 8 and 15 represent the admission and money she spends on snacks.

In an upcoming race, the top 3 finishers will be recognized with the same award. There are 12 people entered in the race.
slavikrds [6]

Answer:

220

Step-by-step explanation:

Given,

The total number of people = 12,

Out of which, top 3 finishers will be recognized with the same award,

So, the total possible way = total combination of 3 people out of 12 people

=^{12}C_3

=\frac{12!}{3!(12-3)!}

=\frac{12\times 11\times 10\times 9!}{3\times 2\times 9!}

=\frac{1320}{6}

=220

Hence, there are 220 ways the top 3 racers can be grouped from the 12 people.

What is the inverse function of f(x)= 4- x/6
Westkost [7]

Answer:

f^{-1}(x) = 6(4-x) = 24-6x

Step-by-step explanation:

Let y=f(x) and swap x and y:

x = 4 - \frac{y}{6}

Then, rearranging for y:

x+\frac{y}{6} = 4

\frac{y}{6}= 4-x

y= 6(4-x) = 24-6x

The median of a data set 8, 21, 17, and 13 is 15. If 17 is changed to 18, what will be the new median? a. 15.5 c. 50 b. 17.5 d.
lubasha [3.4K]

Answer:

Option A) 15.5 is correct

The new median for the new data set is 15.5

Step-by-step explanation:

Given data set is 8,21,17,13

To find the median :

First order the given set of data into least to greatest

The ordered set is 8,13,17,21

Since the given set of data is even

We can take midvalues of data in the set

Median is the mean of two middle values in the data set

Median=\frac{13+17}{2}

=\frac{30}{2}

=15

Therefore Median=15 ( given )

Given that if 17 is changed to 18 then the given set of data  8,21,17,13 is changed into new set  8,21,18,13

To find the median :

First order the new set of data into least to greatest

The ordered set is 8,13,18,21

Since the given set of data is even

We can take two midvalues of new data in the set

Median is the mean of two middle values in the data set

Median=\frac{13+18}{2}

=\frac{31}{2}

=15.5

Therefore New Median=15.5

Therefore option A) 15.5 is correct

The new median for the new data set is 15.5
