Kelvin score 29 points in All-State Basketball team more than Brandon.

We are given that

Brandon averaged 21.25 points per game in 16 games which means that the mean of points made by Brandon in All-State Basketball team of 16 matches is 21.25

So, the total points made by Brandon is

21.25 × 16 = 340

Kelvin averaged 20.5 points per game in 18 games which means that the mean of points made by Kelvin in All-State Basketball team of 18 matches is 20.5

So, the total points made by Kelvin is

20.5 × 18 = 369

we can see that total score made by kelvin is more

The difference is 369- 340 = 29

Hence, Kelvin score 29 points in All-State Basketball team more  than Brandon.

Answer:

  15 : 20 : 8

Step-by-step explanation:

Given ratios a:b = 3:4 and b:c = 5:2, you want the ratio a:b:c in simplest form.

The extended ratio you want can be written only when the number of ratio units associated with 'b' is the same in both ratios. Multiplying the first ratio by 5, we get ...

  a:b = 3:4 = 15:20

Multiplying the second ratio by 4 gives ...

  b:c = 5:2 = 20:8

Now, 20 "ratio units" represent 'b' in both ratios, so we can combine them:

  a:b:c = 15:20:8

__

Additional comment

The value we chose to represent 'b' is the least common multiple (LCM) of the values that represent 'b' in the given (reduced) ratios.

The solutions of the system of equations are:

x = -2, y = 4, z = -2

Here we have the system of equations:

4x - y - 2z = -8

-2x + 4z = -4

x + 2y = 6

To eliminate one variable, we can add the second equation and two times the third equation, we will get:

(-2x + 4z) + 2*(x + 2y) = -4 + 2*6

Now we can simplify that so we get:

4z + 4y = -4 + 12

4*(z + y) = 8

z + y = 8/4  =2

z + y = 2

With that we can write z in terms of y.

z = 2 - y

And with the third equation we can write x in terms of y.

x = 6 - 2y

Replacing that in the first equation we get:

4*(6 - 2y) - y - 2*(2 - y) = -8

Now we can solve this for y.

24 - 8y - y +2y - 4 = -8

20 - 11y = -8

-7y = -28

y = 28/7  = 4

Now that we know the value of y we can find the values of x and z.

x = 6 - 2y = 6 - 2*4 = -2

z = 2 - y = 2 - 4 = -2

The solutions of the system of equations are:

x = -2, y = 4, z = -2

The mean is  12.28

The mode is 9.6.

The median is 10.25.

Mean, median, and mode are measures of central tendency. Mean is the average of a set of numbers. Median is the number that is at the center of a dataset when the dataset is arranged in ascending or descending order. Mode is the number that occurs most frequently in a dataset.

Mean = sum of numbers / total number

(11.3 + 9.9 + 9.6 + 11.5 +9.6 + 11.2 + 10.6) / 6

= 73.7 / 6

= 12.28

The number that occurs most frequently is 9.6. It occurs twice in the dataset. 9.6 is the mode.

The median = (total number + 1) / 2

(6 + 1) / 2

= 7/2 = 3.5 digit

9.6, 9.6, 9.9, 10.6, 11.2, 11.3

-1/2 = 3/8y
Answer:

y = -4/3

answer is y= -4/3

step by step

-1/2 = 3/8y

divide both sides by 3/8 to solve for y

-1/2 divided by 3/8 = 3/8 divided by 3/8y

when you divide fractions you flip the divisor and multiply

-1/2 x 8/3 = y

-8/6 or simplified to -4/3

you can check your work by substituting your y value of -4/3 into your original equation

-1/2= 3/8y

-1/2 = (3/8) (-4/3)

-1/2 = -12/24

-1/2 = -1/2

Answer: 17/18=34/36

11/12=33/36

Step-by-step explanation:

17/18 and 11/12

First find the LCM, least common multiple, of the denominators 18 and 12.

In order to do that, list the factors of 18 and 12 and find the least common factors of them excluding 1.

18: 1, 2, 3, 6, 9, 18

12: 1, 2, 3, 4, 6, 12

Notice any common small factors? Yes they are 2 and 3. Now, multiply them with 18 and 12.

18*2=36

12*3=36

Hence, LCM is 36.

17/18=(17*2)/(18*2)=34/36

11/12=(11*3)/(12*3)=33/36

let me give you a mouthful of something

the domain of f(x) is the range of its inverse, or namely the domain of f(x) is the same set as the range of f⁻¹(x), so for any (a , b) pair on the domain of f(x), there's a (b , a) on the range of f⁻¹(x).

now, that's a bit of of a mumble, but in short it means, if f(x) has a point of (3 , 5), then the graph of f⁻¹(x) has a point which is the same pair but flipped sideways, namely (5 , 3).

that's pretty much true for any function that has an inverse.

The original length of the square garage is 19.1 ft.

The length of the new garage is 23.4 ft and the percentage increase in length is 81.6 %.

Yossi used to have a square garage with 364ft of floor space.

Recently, built an addition to it.

The garage is still a​ square, but now it has​ 50% more floor space

Therefore,

area of a square = l²

where

Therefore,

364 = l²

l = √364

l = 19.0787840283

l = 19.1 ft

Therefore, the original length of the square garage is 19.1 ft.

After 50% increase in the area,

New area = 50 / 100(364) + 364

New area = 546 ft²

Therefore,

546 = l²

l = √546

l = 23.3666428911

l = 23.4 ft

Hence,

percentage increase in length = 19.1 / 23.4 × 100

percentage increase in length = 1910 / 23.4

percentage increase in length = 81.6239316239

percentage increase in length = 81. 6 %

Therefore, the length of the new garage is 23.4 ft and the percentage increase in length is 81.6 %.

When the area A of a rectangle is represented by the formula A= lw, the formula for the length will be l = A / w.

It should be noted that the area A of a rectangle is represented by the formula A= lw

where I is the length

W is the width

It should be noted that based on the information, we want to find the formula to solve for the length.

A = lw

Divide through by w

A/w = lw/w

l = A / w

Therefore, when the area A of a rectangle is represented by the formula A= lw, the formula for the length will be l = A / w.

The complete question is given as follows:

"Ginny wants to join a local dance club that has dance events every week. There are two membership options available: Ginny may become a premier member by paying a fee of $150 per year and attend an unlimited number of dances. Ginny may become a regular member by paying a fee of $50 and then pay $8 per dance she attends. How many dances must Ginny attend such that becoming a premier member will cost less than becoming a regular member? "

A linear function is modeled in slope-intercept form by:

y = mx + b
