A basket ball team played six games. In those games, the team won by 8 points, lost by 10, won by 7, won by 10, lost by 3, and won by 6. What was the mean difference in game scores over the six games?

Answers

Answer: 3

Step-by-step explanation:

Mean simply means average. To calculate mean,we add together all the numbers given and divide them by the amount of numbers.

The Mean here will be:

= [8 +(-10) + 7 + 10 + (-3) + 6]/6

=18/6

= 3

The mean is 3

A. - 9
B. 9
C.-1/9
D.1/9​

Answers

Answer:

D

Step-by-step explanation:

You can ignore the power, since taking something to the power of one doesn't change the answer.

Anything to the 0 is going to be 1, so the answer is one over something.

The denominator is clearly going to be positive, regardless of what the symbol is.

With this in mind, it seems like the answer should be 1/9.

Find the cube root of 343a³b⁶

Answers

Answer:

[tex]7ab^{2}[/tex]

Step-by-step explanation:

You take the cube root of each piece of the term separately:

7 x 7 x 7 = 343, so the cube root of 343 = 7

a^3 = a x a x a, so the cube root of a^3 = a

b^6 = b x b x b x b x b x b = b^2 x b^2 x b^2, so the cube root of b^6 = b^2

The sum of two numbers is 342. One of the numbers is 252. What is the other number?

Answers

Answer:

90

Step-by-step explanation:

342-252=90

So, therefore, 252+90=342

Answer:

90

Step-by-step explanation:

Since the sum is 342 and we already know the first number is 252 we would take away 252 from 342 to get the amount of the second number.

(342-252=90)

We got 90 and to check we would add 252+90 which is =

(252+90=342)

The answer is 90

Submit Answer

Answers

Answer:

y = 8x + 8

Step-by-step explanation:

The y-intercept is already given so we have our b = 8 so y = mx + b becomes y = mx + 8. Now we need to figure out the slope so looking at the chart I need to figure out what number when multiplied by the x value and added to b equals the y value. The answer is 8 because when we multiply it by 1 and add it to 8 we are left with 16, which supports the chart. The equation in slope intercept form is now y = 8x + 8

The slope of a line is -4, and the y-intercept is -3. What is the equation of the line written in slope-intercept form?

y = 4x - 3
y = -4x + 3
y = -4x - 3

Answers

Answer:

y = - 4x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 4 and c = - 3 , thus

y = - 4x - 3 ← equation of line

Hii!

__________________________________________________________

Answer:

Below is all the info you need! ^^

Step-by-step explanation:

Do you remember the slope intercept formula?

y=mx+c is the formula, in which m denotes the slope and c denotes the y intercept.

Suppose we have the slope m and the y intercept c. What is the equation? y=mx+c.

Similarly, if we have the slope -4, and the y intercept -3, the equation is y=-4x+(-3), or y=-4x-3.

8х + 7y= -5
X= -3y - 7

Answers

Answer:

x = 2

y = -3

Step-by-step explanation:

Step 1: Write systems of equation

8x + 7y = -5

x = -3y - 7

Step 2: Solve for y

Substitute 2nd equation into 1st: 8(-3y - 7) + 7y = -5Distribute 8: -24y - 56 + 7y = -5Combine like terms: -17y - 56 = -5Add 56 to both sides: -17y = 51Divide both sides by -17: y = -3

Step 3: Solve for x

Substitute y to find x: x = -3(-3) - 7Multiply: x = 9 - 7Subtract: x = 2

Step 4: Check

Plug in x, y into an original equation to verify it's a solution.

2 = -3(-3) - 7
