The correct answer is:

7/10

Explanation:

Finding the totals of each column and row, we find:

There are 3+2+1 = 6 children in the baseball league.

There are 7+2+1 = 10 children in the softball league.

There are 3+7 = 10 children in the 7-9 division.

There are 2+2 = 4 children in the 10-12 division.

There are 1+1 = 2 children in the 13-15 division.

There are a total of 10+6 = 16 children.

We start with the information that the team is a member of the softball league.  There are 10 children in this league; this is the denominator of the probability.

There are 7 children in the 7-9 division that are in the softball league.  This gives us the probability 7/10.

Answer:

A. 2/5 or 40%

B. 1/5 or 20%

C. 3/5 or 60%

Answer:

1/3

Step-by-step explanation:

Given that two lines are perpendicular.

Slope of green line (one of the lines) is -3.  

To find the slope of other perpendicular line red.

We know that angle between two lines with slopes m1 and m2 would be

[tex]tan^{-1} \frac{m1-m2}{1+m1m2}[/tex]

where m1 is the slope of I line and m2 slope of second line.

Here since two lines are perpendicular angle between them is 90 degrees and hence we get infinity as tan x

this implies denominator for [tex] \frac{m1-m2}{1+m1m2}[/tex]=0

i.e. 1+m1m2 = 0

Or m1m2 =-1

Since one of slope m1 = -3 we have

-3m2= (-1) or m2 = 1/3

Answer:

1/12

Step-by-step explanation:

Since the pizza was cut into 6, each of the slices = 1/6.

But because the pizza was then cut into half, it makes each slice = 1/12

6 x 2 = 12

Therefore the answer is 1/12.

To find the length of Rajesh's shoe, convert the additional length from millimeters to centimeters and add it to Pinky's shoe length. Rajesh's shoe is 21.1 cm long.

The subject of this question is Mathematics and it is suitable for a Middle School student. To find the length of Rajesh's shoe, we need to add the length of Pinky's shoe to the additional length that Rajesh's shoe has. Pinky's shoe is 20.4 cm long, and Rajesh's shoe is 7 mm longer.

Firstly, we need to convert millimeters to centimeters since 1 cm equals 10 mm. Therefore, 7 mm is equivalent to 0.7 cm (since 7 divided by 10 equals 0.7).

Next, we add this length to Pinky's shoe length:

Rajesh's shoe length equals 21.1 cm.

Answer:

y = 2(m + 1/2)^ -25/2

Step-by-step explanation:

vertex form is:

y = 2m^2 + 2m - 12

y + 12 + ( )___ =( ) 2m^2 + 2m + ___

Because a is not one, you must divide the entire right side by the a value, which is 2. Then place the 2 in the parenthesis.

y + 12 + (2)__ = (2) m^2 + m + __

Take half of b, b being one.

Half of be is 1/2. Now square it to get 1/4. Place that value in the blanks.

y + 12 + (2)1/4 = (2) m^2 + m + 1/4

Now simplify the left side and factor the right side.

y+ 12 + 1/2 = 2(m + 1/2)^2

y + 25/2 = 2(m + 1/2)^2

Subtract 25/2 from both sides.

y = 2(m + 1/2)^ -25/2

Answer:

The correct answer is $2,50.

Step-by-step explanation:

The unit rate is what we use to determine the price of a single unit, when something is sold in a group, as in this case 5 ounces.

We have been told that $ 12.50 is the price for 5 ounces, but what we want to know is how much 1 ounce costs.

To determine this, what we must do is divide the total price by the quantity of ounces, in order to determine the unit price:

12.50 / 5 = 2.50

In this way we can verify that the unit price of 5 ounces is $ 2.50

The correct answer is $2,50,  is the unit rate for $12.50 for 5 ounces.

Here, we have,

Answer:

Step-by-step explanation:

If you know what g(x) looks like, you can find f(x). Every y point of g(x) is f(x) + 6.

The general point of g(x) is (x,f(x) + 6). That is the major difference. Just so you can see it visually, the both graphs are shown below.

red: f(x) = x^2

blue: f(x) = f(x) + 6 = x^2 + 6

green: x = 2  With the two points shown that intercept the two given functions.

Purple(?): x = - 2 with the two points shown that intercept the two given functions.

The graphs of both g(x) =x² +6 and f(x)=x² are parabolas. However, while the vertex of the graph of f(x) = x^2 is at the origin, the graph of g(x) = x² + 6 is shifted upwards by six units, with the vertex of g(x) at (0,6). The shape of the two graphs is identical.

The graphs of g(x) =x² +6 and f(x)=x² are both parabolas, but their positions differ on the coordinate plane. The function f(x) = x² is a standard quadratic function with a vertex at the origin (0,0). On the other hand, g(x) = x² + 6 is a vertical translation of the graph of f(x) = x2 upwards by six units. So, the vertex of g(x) is at the position (0, 6). Furthermore, the shape of the two graphs will remain the same as they both have the same degree and leading coefficient.

Answer:

36 - 1/2x = 0

72 minutes

Step-by-step explanation:

there is a total of 3 feet in the pool at the start, 1 ft = 12 in, and 3 ft = 36 in. the pool is losing water, so we have to subtract. it is losing water at a rate of -1/2 in per minute, and we don't know how many minutes it will take

we have to set it equal to 0 because we are trying to find out how long it will be until the pool is completely drained, which is when there will be no water left, so it will be 0

subtract 36 from both sides

-1/2x = -36

divide both sides by -1/2

x = 72

The 20th term of the given arithmetic sequence 8, 21, 34, 47, 60... is 255.

In the field of mathematics, this type of problem is referred to as an arithmetic sequence. An arithmetic sequence is a sequence of numbers in which the difference between any two consecutive terms is constant. This difference is called the common difference.

In your question, the arithmetic sequence provided is 8, 21, 34, 47, 60... Here, the common difference is 13 (i.e., every term after the first is 13 more than the preceding term).

To find any term (let's say the nth term) in an arithmetic sequence, you can use the formula:

nth term = first term + (n - 1) * common difference

Applying this formula to find the 20th term:

20th term = 8 + (20 - 1) * 13 = 8 + 247 = 255
