Answer:

A The mode does not change.

C The mean drops from 185.3 to 172.6.

Step-by-step explanation:

Mean of original data

Mean = (160 + 175 + 166 + 180 + 172 + 178 + 174 + 170 + 178 + 300)/10 = 1853/10 = 185.3

Mean with outlier removed

Mean = (1853 - 300)/9 = 1553/9 = 172.6

The mean drops from 185.3 to 172.6 when the outlier is removed.

Mode

The mode of a data set is the value that occurs most often.

Mode = 178

The mode does not change when you remove the outlier.

GalinKa [24]

Answer:

1/2 = 0.5 / 1/2 of 100 is 50

Step-by-step explanation:

I am not sure what you are trying to say here but I will tell you what I know:

1/2 is equal to 0.5

So 50 x 1/2 = 25  
And 50 x 0.5 = 25

So 100 x 0.5 = 50

 Sandra sells necklaces at a school craft fair. She uses the equation P= 7.5n - (2.25n + 15) to determine her total profit at th
gregori [183]
The way you find profit is to subtract the revenue and the cost
Profit = Revenue - Cost
The revenue is the amount of money coming in, the cost is the amount of money going out. The goal of course is to have the revenue larger than the cost so that the profit is positive. 

So the equation given is
P = 7.5n - (2.25n+15)
and its in the form
P = R - C
where...
R = 7.5n is the revenue equation
C = 2.25n+15 is the cost equation

Focus on the revenue equation
R = 7.5n
which is the same as 
R = 7.50*n

This tells us that Sandra pulls in a total of 7.50*n dollars where n is some positive whole number. It represents the number of necklaces sold. For example, if she sold n = 10 necklaces, then
R = 7.50*n
R = 7.50*10
R = 750
meaning that Sandra has made $750 in revenue

As you can see above, the revenue is computed by multiplying the price per necklace ($7.50) by the number of necklaces sold (n) to get R = 7.50*n

So that's why the answer is $7.50

Note: The 2.25 is part of the cost equation. This is known as the variable cost. It is the cost to make one necklace ignoring the fixed cost (eg: rent). The variable cost often doesn't stay the same, but algebra textbooks often simplify this aspect.

A bulletin board measuring 28 dm long was divided among three subject areas in the ratio 2:2:3. How much space was alothed for e
Sphinxa [80]

Answer: Space was alloted for each subject is 8 dm, 8 dm, 12 dm.

Explanation:

Since we have given the length of bulletin board =28 dm

Let the share of three subject areas be 2x,2x,3x

According to question,

2x+2x+3x=28\\7x=28\\x=\frac{28}{7}\\x=4dm

so x=4 dm

Now,

Space was alloted for each subject is given as below:

First subject =2x=2\times 4=8 dm

Second subject =2x=2\times 4=8 dm

Third subject =3x=3\times 4=12 dm
