What happens to the mean of the data set {2, 4, 5, 6, 8, 2, 5, 6} if the number 7 is added to the data set?

Answers

Answer 1

Answer:

It increases

Step-by-step explanation:

The mean of the given data set of 8 values is 4.75 ([tex]\frac{2+4+5+6+8+2+5+6}{8}[/tex])

Adding 7 into the data set also increase the number of data points to 9, so the mean becomes:[tex]\frac{2+4+5+6+8+2+5+6+7}{9}[/tex], which is equal to 5

Hope this helps

A fruit company delivers its fruit in two types of boxes: large and small. A delivery of 3 large boxes and 8 small boxes has a total weight of 91 kilograms. A delivery of 5 large boxes and 2 small boxes has a total weight of 78 kilograms. How much does each type of box weigh?

Answers

Answer:

the large box weight is 6.50 kg and the small box weight is 13 kg

Step-by-step explanation:

The calculation of each type of box weight is shown below:

Let assume the large box be x

And, the small box be y

Therefore

 3x + 8y = 91.......(i)

5x + 2y = 78.......(ii)

Multiply by 5 in equation 1 and by 3 in equation 2

15x + 40y = 455

15x + 6y = 234

Now deduct the last equation from the above one

34y = 221

y = 6.5 kg

For x, it is

3x + 8(6.5) = 91

3x + 52 = 91

3x = 91 - 52

3x  = 39

x = 13 kg

Hence, the large box weight is 6.50 kg and the small box weight is 13 kg

Hey, I have already answered these all questions except the last question in your previous question. Make sure to see them.

For the last question, the answer would be the second choice as when times keep flowing, the distance still remains the same (not to be confused with speed.)

Basically when times keep going, the distance will stay the same without any changes.

Answers

Answer: All of the values that can go into a relation or function (input) are called the domain. The domain is the set of all first elements of ordered pairs (x-coordinates). The range is the set of all second elements of ordered pairs (y-coordinates). Only the elements "used" by the relation or function constitute the range.

an
Solve

Answers

Answer:

n=0

Step-by-step explanation:

simplifying

6 = 1 + -8n + 5

Reorder the terms:

6 = 1 + 5 + -8n

Combine like terms: 1 + 5 = 6

6 = 6 + -8n

Add '-6' to each side of the equation.

6 + -6 = 6 + -6 + -8n

Combine like terms: 6 + -6 = 0

0 = 6 + -6 + -8n

Combine like terms: 6 + -6 = 0

0 = 0 + -8n

0 = -8n

Solving

0 = -8n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '8n' to each side of the equation.

0 + 8n = -8n + 8n

Remove the zero:

8n = -8n + 8n

Combine like terms: -8n + 8n = 0

8n = 0

Divide each side by '8'.

n = 0

Simplifying

n = 0

N=0! Easy . Pls thanks !!

I got a 12 discount on a pair of jeans and a 25% discount on a t-shirt the original price of the jeans was $100 and thatof the T-shirt $50, how much did i pay for both items? (NEED EQUATION AND WORK)​

Answers

Answer:

$125.50

but I'm not sure

Step-by-step explanation:

100÷100=1

1×12=12

100-12=88

jeans with discount = $88

50÷100=0.5

0.5×25=12.50

5000-1250=3750

t-shirt with discount = $37.50

3750+8800=12550

Answer:

125.5

Step-by-step explanation:

100 x .12= 12

100-12=88

50 x .25 = 12.5

50-12.5 = 37.5

88 + 37.5 = 125.5

Step-by-step explanation:  

   19

x  15

  95

 190

285

To get the 95, multiply 9 x 5, which is 45. Then, carry over the 4 and multiply 1 x 5, which is 5. Add 5 + 4, which is 9, so then you have 95.

To get the 190, you first have to write a 0 in the unit's place because we are working with the tens. Then, you multiply 9 x 1, which is 9. You then multiply

1 x 1, which is 1.

For the final step, you add 95 + 190 = 285 and this is your answer.
