Removing the -6 makes the average go from 4.1 to 5.2

Removing the -6 makes the median go from 4 to 5

Step-by-step explanation:

Average:

-6+3+3+3+3+5+6+6+8+10 = 41

41/10 = 4.1 (This is the mean/average)

If we remove -6, then:

3+3+3+3+5+6+6+8+10 = 47

47/9 = 5.2222 (This would be the new average)

So removing the -6 makes the average go from 4.1 to 5.2

Median:

The median of (-6+3+3+3+3+5+6+6+8+10) is between 3 and 5, so the median is 4.

Without -6, the median of (3+3+3+3+5+6+6+8+10) is 5.

So removing the -6 makes the median go from 4 to 5

At the start of the football game, there were 840 fans in the stadium. It began to rain during halftime, so 10% of the fans went home.
During the 3rd quarter of the game, the visiting team scored five touchdowns, so 25% of the remaining fans went home.
How many fans were in the stadium after the 3rd quarter?

Answers

After the third quarter there were 567 fans in the stands
840x.90(total-part)=756 fans at 1/2 time
756x.75= 567 fans after the third quarter

The function f (x) = 6x + 13 defines a
sequence for x > 1. What are the first three
terms of the sequence?

Answers

Answer:

15, 21, 27

Step-by-step explanation:

Given the function :

f(x) = 6x + 13 ; which defines a sequence for x > 1

The first three terms of the sequence ;

x > 1 ;

Hence x = 2, 3, 4

The sequence :

f(2) = 6(2) + 3 = 12 + 3 = 15

f(3) = 6(3) + 3 = 18 + 3 = 21

f(4) = 6(4) + 3 = 24 + 3 = 27

A box contains 15 large marbles and 11 small marbles. Each marble is either green or white. 9 of the large marbles are green, and 3 of the small marbles are white. If a marble is randomly selected from the box, what is the probability that it is small or white? Express your answer as a fraction or a decimal number rounded to four decimal places.

Answers

Answer:

The probability of selecting a small or white marble is 10/13

Step-by-step explanation:

The total number of marbles is 15 + 11 = 26 marbles

The probability that we want to calculate is if the marble selected is small or white.

So we need to find the number of small marbles as well as the number of white marbles

We can construct a table to see the distribution of the marbles. Please check the attachment for this.

From the table , we can see that there are 11 small marbles and a total of 9 white marbles

The probability of selecting a white marble is;

number of white marbles/total number of marbles = 9/26

The probability of selecting a small marble will be ;

number of small marbles/total number of marbles = 11/26

In probability, whenever we have or, we tend to add

So therefore, the probability of selecting a white or small marble = Probability of selecting a white marble + Probability of selecting a small marble

Mathematically, that would be 9/26 + 11/26 = 20/26

So the probability is 10/13
