Three randomly selected households are surveyed. /The numbers of people in the households are 1, 3, and 8. Assume that samples o

f size n =2 are randomly selected with replacement from the population of 1, 3, and 8. Listed below are the nine different samples
1,1 ; 1,3 ; 1,8 ; 3,1 ; 3,3 ; 3,8 ; 8,1 ; 8,3 ; 8,8

The question is asking to find the variance for the said samples in the problem ans use the sample data to determine each variance, and base on my further computation and further calculation, I would say that the answer would be the following:
#1. 3.3 -> 1 and 3 -> 2/9
#2. 1-> 0->3/9
#3. 6.3 - > 8 and 3-> 2/9
#4 49-> 1 and 8-> 2/9

What is 9 ounces equal to in pounds? please answer in fractions:)
Tema [17]

Answer:

9/16

Step-by-step explanation:

First, note that 10000 multiplied by .5625 will get rid of the decimal point. Therefore, make a fraction where the numerator is .5625 times 10000 and denominator is 10000 like this:

   

.5625 x 10000

 

   

10000

Next, multiply the numbers in the numerator together and keep the denominator as is. Now our fraction looks like this:

   

5625 /10000

The greatest common factor of 5625 and 10000 is 625, which means you can divide the numerator and denominator by 625 and keep the same value:

   

5625 ÷ 625 /10000 ÷ 625

And when calculating the numerator and denominator in our fraction above, we get .5625 as a fraction in the simplest form possible:

 .5625  =  

   

9 /16

Firlakuza [10]

Answer:

the difference is 143

explanation

How to Find the Difference between Two Numbers. To find the difference between two numbers, subtract the number with the smallest value from the number with the largest value. The product of this sum is the difference between the two numbers. Therefore the difference between 45 and 100 is 55.

so 120-(-23) is 141

Beyonce is solving a system of equations:
aivan3 [116]

Answer:

x=5, y=4. (5, 4).

Step-by-step explanation:

2x-3y=-2

4x+y=24

------------------

-2(2x-3y)=-2(-2)

4x+y=24

----------------------

-4x+6y=4

4x+y=24

--------------

7y=28

y=28/7

y=4

4x+4=24

4x=24-4

4x=20

x=20/4

x=5

each day last week, Ms. wilson walked3/4 mile. what is the total distance, in miles, that Ms. Wilson walked in 4 days?
zloy xaker [14]
Hey there! :D

Since she walks 3/4 a mile a day, we can multiply that by 4.

3/4= .75

4*.75= 3

She walked 3 miles in 4 days.

I hope this helps!

Solve the inequality: -7y - 3x < 21
SashulF [63]

Answer:

x>  -7/3y -7

Step-by-step explanation: -7y-3x<21

Step 1: Add 7y to both sides.

−3x−7y+7y<21+7y

−3x<7y+21

Step 2: Divide both sides by -3.

-3x/-3 < 7y+21/-3

x>-7/3y -7
