Answer: 11

Students have both a brother and a sister

Step-by-step explanation:

I don't think probability should be used for this question because the answer is quite clear

So in a class of 25 students

5 students don't have a sibling

So 25-5=20

Total number of siblings=14+17=31 siblings in total

So 20 people have 31 siblings

31-20=11

So the answer should be 11

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings. The probability that a student who has a brother also has a sister is 11/25.

Suppose that there are finite elementary events in the sample space of the considered experiment, and all are equally likely.

Then, suppose we want to find the probability of an event E.

Then, its probability is given as

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text{Number of total cases}} = \dfrac{n(E)}{n(S)}[/tex]

where favorable cases are those elementary events that belong to E, and total cases are the size of the sample space.

In a class of 25 students, 14 have a brother and 17 have a sister. There are 5 students who do not have any siblings.

So in a class of 25 students

5 students don't have a sibling

then, 25-5=20

Total number of siblings = 14+17

= 31 siblings in total

So, 20 people have 31 siblings

= 31 - 20

= 11

So, the probability that a student who has a brother also has a sister

= 11/ 25.

Answer:

20 cm

Step-by-step explanation:

So from the problem we get that the two sides of the rctangle are 16 cm 12 cm which are base perpendicular of the right angle triangle. H = 20 cm. So the diagonal of the rectangle = 20 cm.

Answer:

20 cm

Step-by-step explanation:

Here's your solution

=> length of rectangle = 16 cm

=> width of rectangle = 12 cm

=> Diagonal of rectangle = √(l^2 + w^2 )

=> Diagonal = √(16^2 + 12^2)

=> Diagonal = √(256 + 144)

=>. Diagonal = √400

=> Diagonal = 20 cm

Answer:

Solution (4,3)

Step-by-step explanation:

2x-7y= -13

(8x-7y=11)x-1

2x-7y= -13

-8x +7y= -11

[tex]\frac{-bx}{-6} =\frac{-24}{-6}[/tex]

x= 4

__________

2x-7y= -13

2(4)-7y=-13

8-7y= -13

subtract 8 from both sides

[tex]\frac{-7y}{-7} =\frac{-21}{-7}[/tex]

divide by -7

y= 3

Answer:

Graph the line using the slope and y-intercept, or two points.

Answer:

the slope of both lines are the same.

Step-by-step explanation:

Given the following segment of the Quadrilateral EFGH on a coordinate  Segment FG is on the line 3x − y = −2,

segment EH is on the 3x − y = −6.

To determine their relationship, we can find the slope of the lines

For line FG: 3x - y = -2

Rewrite in standard form y = mx+c

-y = -3x - 2

Multiply through by-1

y = 3x + 2

Compare

mx = 3x

m = 3

The slope of the line segment FG is 3

For line EH: 3x - y = -6

Rewrite in standard form y = mx+c

-y = -3x - 6

Multiply through by-1

y = 3x + 6

Compare

mx = 3x

m = 3

The slope of the line segment EH is 3

Hence the statement that proves their relationship is that the slope of both lines are the same.

The slope of the lines is the same, the line segments FG and EH are parallel to each other and are the opposite sides of the quadrilateral.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is constant.

The slope of the line segment FG can be found by comparing the equation with the equation of the line. Therefore,

y = mx + c

-2 = 3x - y

- 2 - 3x = -y

y = 3x + 2

Thus, the slope of the equation is 3.

The slope of the line segment EH can be found by comparing the equation with the equation of the line. Therefore,

y = mx + c

3x - y = -6

-y = 6 - 3x

y = 3x+6

Thus, the slope of the equation is 3.

Since the slope of the lines is the same, the line segments FG and EH are parallel to each other and are the opposite sides of the quadrilateral.

For circle:

Diameter = 6 m

Radius (r) = 6/2 = 3 m

Area of shaded region = Area of parallelogram - Area of circle

Answer:

C. f(x) = x - 9 is the function that accurately represents f

Step-by-step explanation:

Plug in a value from the table to check which function is correct

1. Plug in x = 3 and check if you get -6.

A. f(3) = -4(3) + 12 = -12 + 12 = 0 -> 0 ≠ -6 so A is not the correct function

B. f(3) = 3(3) + 2 = 9 + 2 = 11 ≠ -6 so B is not the correct function

C. f(3) = 3 - 9 = -6 = -6 so C is the correct function

D. f(3) = -5(3) - 1 = -15 - 1 = -16 ≠ -6 so D is not the correct function

Answer:

the constant is 3 the coefficant is y and the varible is a and the factors of 9 are 18 and 27

Step-by-step explanation:

Answer:

The constant is 3

The coefficient is 12

The variables are both A and Y.

Disclaimer: I'm not sure about this next one, but I believe it's right.

9x factors are 3x, 1, and 9x.

If you wanted me to factor it, then it'd be something like 3x(3)

Step-by-step explanation:

A constant is a number that is by itself. Variables can't be constants. In this case, the only number that is by itself, that isn't a variable is 3. Therefore, 3 is the constant.

A coefficient is a number that accompanies the variable. Normally in a math equation, a variable is multiplied by a number. In this case, A is being multiplied by 12, so 12 is the coefficient.

The variable is the letter that represents any number. In this case, there are two variables, A and Y. They both represent numbers that can differ. So, A and Y are the variables.

The factors of 9x are 3x, 3, 1x, 1, 9x, and 9.

9 times 1x is 9x, 9x times 1 is also 9x.

3 times 3x is 9x, and 3x times 3 is again, 9x.
