Select the correct answer.
Mr. Svenson devised a training technique for goalkeepers at his soccer academy. He believes that if goalkeepers train using this technique, they
will improve their goal-saving rate in games. The goal-saving rate is the ratio of the number of saves made by a keeper to the number of
opposition shots that were on target.
To test how effective his new training technique is, Mr. Svenson splits the goalkeepers at the academy into two groups. One group trains using
traditional methods, and the other group trains using the new technique. Mr. Svenson compares the goal-saving rates of keepers from the two
groups in games played against the same level of competition. He finds that keepers who trained using his new technique had a higher
goal-saving rate than those who used traditional methods.
What does the goal-saving rate of keepers represent in this case?
A.
the response group
B.
the response variable
C. the control group
D. the explanatory variable

260 people would fit if they were spaced apart

Step-by-step explanation:

why 260 because 1824 SQUARE feet means we have to times it by 2 since square is 2 now we got 3,648 area. We now have to divide it by 14 feet beacuse when you multipy  14 to 260(people) we would get 3,648 area

Answer:

Linear, y=6x-21

Step-by-step explanation:

Graph the answer to get an idea of the shape: linear.

Use y=mx+b and m=y2-y1/x2-x1 to find formula

m=y2-y1/x2-x1=3-(-9)/4-2=12/2=6

y=6x+b

9=6(5)+b

9-30=b=-21

y=6x-21

Answer:

9

Step-by-step explanation:

We are given that

Cost of each banana=$0.90

Cost of each orange=$0.80

Ava have total money=$15

We have to find the number of each if Ava wants to buy an equal amount of bananas and oranges at most.

Let x be the number of each.

According to question

[tex]0.9x+0.8x=15[/tex]

[tex]1.7x=15[/tex]

[tex]x=\frac{15}{1.7}[/tex]

[tex]x=8.8\approx 9[/tex]

[tex]x=9(approximately)[/tex]

Hence, number of banana bought=9

Number of oranges bought=9

Answer:

y=4x+6

Step-by-step explanation:

y-y1=m(x-x1)

y-(-2)=4(x-(-2))

y+2=4(x+2)

y=4x+8-2

y=4x+6

Answer:

$50

Step-by-step explanation:

1. First you need to divide 70 by 7.

2. Your answer should be 10.

3. You then need to multiply the product, 10 by 5.

4. You answer should be 50 and because we are using this in a money situation the answer is $50.

Answer:

50

Step-by-step explanation:

Answer: 56.9

Step-by-step explanation:

Let the original number be denoted by x.

We are informed that when the number is increased by 5.5%, the result is 60. This can be represented by:

x + (5.5% of x) = 60

x + (0.055 × x) = 60

x + 0.055x = 60

1.055x = 60

x = 60/1.055

x = 56.9

The original number is 56.9

Answer:

2:3

Step-by-step explanation:

1: 121, 2: 59, 3: 59

This is for the first graph because if you look at the bottom half of a circle is 180 so since one is 121 you just have to subtract 121 from 180 and you have your answer

Answer:

A= 20 + 0.75*j

Step-by-step explanation:

Giving the following information:

You have $20 and earn $0.75 for each cup of orange juice you sell.

To calculate the total amount of dollars (A), we need to use the following formula:

A= 20 + 0.75*j

j= number of cups

For example, for 15 cups:

A= 20 + 0.75*15

A= $31.25

Answer:

c < 2

Step-by-step explanation:

We have an inequality and are asked to solve for the variable "c."

4c + 2 < 10

To solve for c, we need to get it by itself, isolate it in every way possible.

4c + 2 < 10

Subtract 2 from both sides :

4c < 8

Now before we move on, take this into consideration, sometimes the inequality sign can be switched but under one condition. And that is when you divide both sides by a negative, since we are not dividing by a negative, no switch of the sign is needed.

Divide 4 from both sides to get c alone :

c < 2

Answer:

y = 12x

Step-by-step explanation:

From the question, we are told that a person consumes 12 gallons of water each day

Now, we want to complete an equation

From the question, x is the number of days and y is the amount of water consumed

Thus, mathematically, we have the equation as;

y = 12x

since in the first day, 12 gallons is consumed, the second will be 12 * 2 and so on

So the amount of water depends on rate number of days

Answer:

12

Answer:

Step-by-step explanation:

There are more adults than children so the ratios made have to depict this.

These ratios should add up to 16.

Three different ratios:

11 adults : 5 children

9 adults : 7 children

13 adults : 3 children

The above will all add up to 16 and show more adults than children.

The different ratios of adults to children that might be on the bus is;

14 : 2, 13 : 3, 12 : 4, 11 : 5, 10 : 6, 9 : 7

We are given;

The people on the bus consist of adults and children.

We are told that;

Thus, the different possibilities for ratio between

adults and children will be 2 numbers that add up to 16 which must not be equal. Thus, we have;

14 : 2

13 : 3

12 : 4

11 : 5

10 : 6

9 : 7

Answer:

You can figure out prime numbers by simply knowing that you can divide that number not more than one. For example, you could know that a prime number is 7 because you can only divide it once like 7 divided by 1. While for number 14, you can divide it twice which isn't a prime number because there is 14 divided by 2 and 14 divided by 1 which is more than one to divide. That's possibly an easy way to understand how to figure them out.

Step-by-step explanation:

In an isosceles triangle, the angle bisector from the 3rd angle to the opposite side is a perpendicular bisector, so you split the isosceles triangle into two congruent right triangles.

This technique of 'splitting the isosceles' is used a LOT.
