Answer:

Step-by-step explanation:

First Add the scores.

Score Total = 787 + 615 + 550 + 674 + 784+ 773 + 620 + 720 + 704

Score Total = 6227

Now divide by the number of members of the sum.

Number of members = 9

The average score = Total Score / number of members

The average score = 6227 / 9 = 691.9

The average score = 692 which is C

Answer:

x=3 and y=2

Step-by-step explanation:

Rewrite equations:

3x−y=7;2x+y=8

Step: Solve3x−y=7for y:

3x−y=7

3x−y+−3x=7+−3x(Add -3x to both sides)

−y=−3x+7

−y

−1

=

−3x+7

−1

(Divide both sides by -1)

y=3x−7

Step: Substitute 3x−7 for y in 2x+y=8:

2x+y=8

2x+3x−7=8

5x−7=8 (Simplify both sides of the equation)

5x−7+7=8+7 (Add 7 to both sides)

5x=15

5x5

=

15/5

(Divide both sides by 5)

x=3

Step: Substitute 3 for x in y=3x−7:

y=3x−7

y=(3)(3)−7

y=2(Simplify both sides of the equation)

Answer:

6in

Step-by-step explanation:

Let's organize what we know.

- 5gal/1in

- 30gal tank

Since we need to find the inches of the fish he can have, we can set up a proportion like this:

5/1=30/x

We can cross multiply.

5x=1(30)

Simplify: 1*30=30

5x=30

Now we can isolate the variable.

5x=30

x=6

Answer:

D. No, because it fails the vertical line test

Step-by-step explanation:

A function can only have 1 output for each input. If you are able to draw a vertical line and it touches the graph twice, then it has failed the vertical line test and is therefore not a function.

Answer:

3y = -x + 17

Step-by-step explanation:

Equation of a line is in the form:

y = mx + c

where m is slope and c is intercept

Mathematically;

slope m = (y2-y1)/(x2-x1)

= (6-4)/(-1-5) = 2/-6 = -1/3

So the equation is now;

y = -x/3 + c

Multiply through by 3

3y = -x + 3c

To get c substitute the value of a point say (5,4)

x = 5 and y = 4

3(4) = -5 + 3c

12 = -5 + 3c

12+ 5 = 3c

3c = 17

c = 17/3

So the equation is

y = -x/3 + 17/3

and that is

3y = -x + 17

Answer:

P(1 red gumball and 1 blue balloon) =[tex]\frac{2}{15}[/tex]

Step-by-step explanation:

There are two jars.

One jar has 2  red, 3 green and 1 yellow gumball.So, there are 2+3+1=6 gumballs.

Another jar has 2 blue and 3 purple balloons. Totally there are 2+3=5 balloons.

So,

Probability of drawing 1 red gumball from jar 1 =[tex]\frac{2}{6}[/tex]

Probability of drawing 1 blue balloon =[tex]\frac{2}{5}[/tex]

So, P( 1 red gumball, 1  blue balloon)= [tex]\frac{2}{6} *\frac{2}{5} =\frac{2}{15}[/tex]

Answer:

Step-by-step explanation:

1:    x^2 + 6x = - 7

2:   x^2 + 6x + (6/2)^2 = -7 + (6/2)^2

2:   x^2 + 6x + 9 = - 7 + 9    This might be a 2

2:   x^2 + 6x + 9 = 2

3:   (x + 3)^2 = 2

4:   √(x + 3)^2 = √2  

5:    x + 3 = +/- √2
