What would happen to the variance of a data set if we multiplied every observation by S?

Solution:

Let's reread the part of the question carefully.

{one more} {than one third the number of dolls than Sally has}

       ↥                                                 ↥                          

       1                                                s/3

This means that Anne has s/3 + 1 dolls, which is 9 dolls.

Hence, the equation that represents the word problem is S/3 + 1 = A.

Answer:

D

Step-by-step explanation:

1. Add the costs together 10.98+13.95+22.56=47.49

2. To get an average, divide by the amount of numbers you added together. We added 3 numbers together (10.98+13.95+22.56) so we divide by 3.

47.49/3=15.83

The option closest to our number is D so we round up.

$15.83->$20

Have a good day.

Answer:

C

x = 36-4

x = 32

Step-by-step explanation:

1. We have to divide 4200 by a number which is a multiple of 10.

Let us assume that the number is 20, which is a multiple of 10.

Now, after division the quotient will be .

2. We have to check whether the quotient is multiple of 10 or not.

Here, the quotient is 210 which is a multiple of 10.

Hence, the required number which is a multiple of 10 is 20.

The number of comedy DVDs will be equal to 604.

The percentage is defined as representing any number with respect to 100. It is denoted by the sign %. The percentage stands for "out of 100." Imagine any measurement or object being divided into 100 equal bits.

Given that the total number of DVDs are 1830 and the percentage of comedy DVDs is 33%.

The number of comedy DVDs will be calculated as,

N = ( 1830 x 33%)

N = (1830 x 33 ) / 100

N = 604

Therefore, the number of comedy DVDs will be equal to 604.

Answer:

  a)  21, 34.5, 54.75, 85.125

Step-by-step explanation:

All of the answer choices differ in the first term, so that is the only one you need to figure here. However, we will do them all, so you can see it done.

We note that x > 0 for all of the values of x that we need to use. That means the recursive relation is the one we're using for computation.

f(1) = 3/2·f(0) +3 = (3/2)(12) + 3 = 18 +3 = 21 . . . . . . matches choice (a)

f(2) = 3/2·f(1) +3 = (3/2)(21) +3 = 63/2 +3 = 69/2 = 34.5

f(3) = 3/2·f(2) +3 = (3/2)(34.5) +3 = 51.75 +3 = 54.75

f(4) = 3/2·f(3) +3 = (3/2)(54.75) +3 = 82.125 +3 = 85.125

When you're computing for sequential input values, each depends on the previous value you computed.

Answer:

12.22 would be her total cost after including 8% of tax.

Step-by-step explanation:

$2.29x3=$6.87

$6.87+1.89x2=$10.65

$10.65+$1.49=$12.14

$12.14+¢.08= $12.22

This is what I think is the answer from my work.

Answer:

1. B
2. A
3. D
4. C

The cost per friend is $6.84.

The first step is to determine the total cost of the vegetables the two friends bought.

Total cost of the vegetables = ( 1 x $2.82) + 4.19 X 2 + (1.24 x 2) = $13.60

In order to determine the cost per friend, divide the total cost of the vegetables by the number of friends that purchased the items.

$13.6 / 2 = $6.84

Answer

125,000 tons of garbage per landfill

Step-by-step explanation:

250 million total tons of garbage was sent to 2,000 landfills. Since it is assumed each landfill gets an equal amount of garbage, we can easily divide.

250,000,000 / 2,000 = 125,000 tons of garbage per landfill

henceforth, each landfill received 125,000 tons of garbage

Answer:

  the correct choice is marked

Step-by-step explanation:

The tip is 20% of the bill:

  20% × $124.00 = $24.80

When that is added to the bill, the total is ...

  $124.00 +24.80 = $148.80

Answer:

A.

Step-by-step explanation:

You need to find 20% of the order to find the tip then add that to the original bill.

So, you need to solve 124x0.20 to get 24.80. That's the tip.

Next, add 124+24.80=148.80. There is your answer.

Hope you get an A! <3
