Answers

Answer: A) 20.9 ; B) 34years

Step-by-step explanation:

Given the following :

AGE (X) - - - - - - - 19 - -20 - - - 21 - - - 22 - - - 23

FREQUENCY (F) - 2 - - 3 - - - - 1 - - - - 4 - - - - 1

A)

MEAN(X) = [AGE(X) × FREQUENCY (F)] ÷ SUM OF FREQUENCY

F*X = [(19 * 2) + (20 * 3) + ( 21 * 1)+(22 * 4)+(23 * 1)]

= 38 + 60 +21 + 88 + 23 = 230

SUM OF FREQUENCY = 2 + 3 + 1 + 4 + 1= 11

MEAN(X) = 230 / 11

X = 20.9

B)

WHEN A NEW PLAYER WAS ADDED :

MEAN (X) = 22

Let age of new player = y

Sum of Ages = 19 + 19 +20 + 20 + 20 + 21 + 22 + 22 + 22 + 22 + 23 + y

Number of players = 11 + 1 = 12

Mean(x) = sum of ages / number of players

New mean (x) = 22

x = (230 + y) / 12

22 = (230 + y) / 12

Cross multiply

264 = 230 + y

y = 264 - 230

y = 34 years

I think you know Bc the other person already said it so give em brainlest

Answer:

 =  1 0

Step-by-step explanation:

Solve

1. Combine like terms

2  +  2 0  + 2  =  6 0

4  +  2 0  =  6 0

2. Subtract  20  from both sides of the equation

4  +  2 0  =  6 0

4  +  2 0  −  2 0  =  6 0  −  2 0

3. Simplify

Subtract the numbers

4  +  2 0  −  2 0 =  6 0  −  2 0

4  =  6 0  −  2 0

Subtract the numbers

4 =  6 0  −  2 0

4  =  4 0

4. Divide both sides of the equation by the same term

4x = 40

4x/4 = 40/4

5. Simplify

Cancel terms that are in both the numerator and denominator

4x/4 = 40/4

x = 40/4

Divide the numbers

x = 40/4

x = 10

Answers

Answer:

7 as a halfway of a line

3 if you were using points on a graph

Step-by-step explanation:

10--4/2=7

use midpoint formula for 3

The number that is exactly halfway between -4 and 10 is 3

The distance between two point is the amount of length between the two points.

Midpoint of -4 and 10 is 10 - (-4) gives 10 + 4

The distance between -4 and 10 is 14 units

Halfway of the length between -4 and 10 is 14 /2 (7)

The number that is exactly halfway between -4 and 10 = -4 + 7 or 10 - 7 = 3

The number that is exactly halfway between -4 and 10 is 3

Sarah earns $400 per week and spends 15% of her earnings on transportation. How much does Sarah spend on transportation every week? *

Answers

Answer:

60 dollars a week.

Step-by-step explanation:

Just take 15 percent of 400, then you get your answer

think of it like this: ?/400$ = 15/100. We are trying to find 15 % of 400, so that’s what the “?” represents.
thinking of it like fractions, cross multiply the numbers you have in this situation (400x15) =6,000
then you divide that answer by the number left (100)
(6,000 / 100) = 60

So the answer is 60$, 15% of 400$ is 60$

The conditional relative frequency table below was generated by column using frequency table data comparing the number of calories in a meal to whether the meal was prepared at home or at a restaurant.

A 4-column table with 3 rows titled number of calories and location of meal preparation. The first column has no label with entries greater than or equal to 500 calories, less than 500 calories, total. The second column is labeled home with entries 0.15, 0.85,1.0. The third column is labeled restaurant with entries 0.55, 0.45, 1.0. The fourth column is labeled total with entries 0.28, 0.72, 1.0.

A nutritionist attempts to determine an association between where food is prepared and the number of calories the food contains. Which is most likely true?
An association cannot be determined because the value 0.55 is similar to the value 0.45.
There is an association because the value 0.15 is not similar to the value 0.55.
There is an association because the sum of each column is 1.0.
An association cannot be determined because the sum of the rows going across is not 1.0.

Answers

There is an association because the value 0.15 is not similar to the value 0.55

For the nutritionist to determine whether there is an association between where food is prepared and the number of calories the food contains, there must be an association between two categorical variables.

The conditions that satisfy whether there exists an association between conditional relative frequencies are:

1. When there is a bigger difference in the conditional relative frequencies, the stronger the association between the variables.

2. When the conditional relative frequencies are nearly equal for all categories, there may be no association between the variables.

For the given conditional relative frequency, we can see that there exists a significant difference between the columns of the table in the picture because 0.15 is significantly different from 0.55 and 0.85 is significantly different from 0.45

We can conclude that there is an association because the value 0.15 is not similar to the value 0.55

The Jacksons are taking out a $35,000 loan to remodel their home. The tables below show the rates for a 1-year and 5-year loan from two different lenders. Complete each table to calculate the total repayment and interest paid for each loan offer.

Answers

Answer:

look at the screenshot

Step-by-step explanation:

look at the screenshot

The table for total repayment and interest paid for each loan offer:

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570

What is simple interest?

Simple interest is an amount which is calculated for a certain period of time and for a certain rate, in simple interest calculation there are three factors which we consider: principal amount(P), rate(R) and time(T).

Formula;    Simple Interest(I) =  P × R × T/100

For the 1-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest = $35,000 + (0.065 x $35,000)

                                                               = $37,275

Total interest paid = $37,275 - $35,000

                               = $2,275

For the 5-year loan, the total repayment and total interest paid can be calculated as follows:

Total repayment = Principal + Interest

                            = $35,000 + (0.082 x $35,000 x 5)                

                            = $41,570

Total interest paid = $41,570 - $35,000 = $6,570

Loan offer Interest rate Total repayment Total interest paid

1-year loan 6.5%         $37,275                 $2,275

5-year loan 8.2%         $41,570                 $6,570
