Step-by-step explanation:

Given:

Two fair number cubes i.e. two dice consisting the numbers 1, 2, 3, 4, 5, 6 on their faces and have equal probability of each number.

The dice are rolled.

To find:

Probability of getting the sum of two numbers as 4.

Solution:

First of all, let us have a look at the total possibilities when two dice are rolled:

([1][1], [1][2], [1][3], [1][4], [1][5], [1][6],

[2][1], [2][2], [2][3], [2][4], [2][5], [2][6],

[3][1], [3][2], [3][3], [3][4], [3][5], [3][6],

[4][1], [4][2], [4][3], [4][4], [4][5], [4][6],

[5][1], [5][2], [5][3], [5][4], [5][5], [5][6],

[6][1], [6][2], [6][3], [6][4], [6][5], [6][6])

These are total 36 possible outcomes.

For getting a sum as 4:

Possible number of favorable cases are 3 (as highlighted in BOLD in above)

Formula for probability of an event E can be observed as:

[tex]P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}[/tex]

Required probability is:

Answer:  see proof below

Step-by-step explanation:

Use the Sum & Difference Identity: tan (A - B) = (tanA - tanB)/(1 + tanA tanB)

Use the Half-Angle Identity: tan (A/2) = (1 - cosA)/(sinA)

Use the Unit Circle to evaluate tan (π/4) = 1

Use Pythagorean Identity:     cos²A + sin²A = 1

Answer:

Option R

Step-by-step explanation:

The point S is the end point of ray.

What is line?

A line has length but no width, making it a one-dimensional figure. A line is made up of a collection of points that can be stretched indefinitely in opposing directions. Two points in a two-dimensional plane determine it.

According to the given information,

A ray's endpoint is a single point that denotes the conclusion of a line segment. In this instance, only one of the three lines that extend from point S contains a ray's terminus.

We must comprehend a ray's qualities in order to establish which location is the endpoint of a ray.

A ray originates at a single place and travels in one direction indefinitely. The beginning of the line segment is the endpoint of a ray.

We can see from the provided lines that the vertical line runs from point S via point R. Since it doesn't go on forever in one direction, this is not a ray example.

Similar to the vertical line,

The horizontal line also extends from point S through point T,

But it does not go on forever.

The third line is a ray because it is infinitely long in one direction and extends right and up from point S via point U.

Therefore, point S, the beginning of the line, is the endpoint of this ray.

Answer:

Below

Step-by-step explanation:

● x-20 = y+20 (1)

● 2(y-22) = x+22 (2)

This is a system of simulataneous equations

Let's simplify the expressions first

● x -20 = y + 20 (1)

Add 20 to both sides

● x -20 + 20 = y+20 +20

● x = y + 40 (1)

● 2(y-22) = x+22 (2)

● 2y - 44 = x +22

Substrat 22 from both sides

● 2y-44-22 = x+22-22

● 2y -66 = x (2)

This is the new system:

● x = y+40 (1)

● x = 2y-66 (2)

Substract (2) from (1)

● x-x = y+40-(2y-66)

● y+40-2y+66 = 0

● -y +106 = 0

● y = 106

Replace y with 106 in (1)

● x = y +40

● x = 106+40

● x = 146

So the solutions are (146,106)

given data:

length of a sid = 48m

cost of ploughing the field = rs 25/m

cost of fencing the field = rs 18/m

solution:

we know a square has four equal sides. so total length of the field is

= m ( 48 + 48 +48 + 48 )

= 192m

cost of ploughing the field

= 192m * rs 25

= rs 4800

cos of fencing the field

Step-by-step explanation:

Area of the triangle = ½*AB*CD

First of all, find the length of AB and CD using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

[tex] AB = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

A(-6, 2) => (x1, y1)

B(3, 2) => (x2, y2)

[tex] AB = \sqrt{(3 -(-6))^2 + (2 - 2)^2} [/tex]

[tex] AB = \sqrt{(9)^2 + (0)^2} = \sqrt{81} = 9 [/tex]

[tex] CD = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex]

C(-2, 6) => (x1, y1)

D(-2, 2) => (x2, y2)

[tex] CD = \sqrt{(-2 -(-2))^2 + (2 - 6)^2} [/tex]

[tex] CD = \sqrt{(0)^2 + (-4)^2} = \sqrt{16} = 4 [/tex]

Step-by-step explanation:

Given

Represent 1950 Population with P and 2003 Population with Q

[tex]Q = 19.5\ million[/tex]

Required

Determine the value of P

From the question; we have that

[tex]Q = 2\ million + 5 * P[/tex]

Substitute 19.5 million for Q

[tex]19.5\ million = 2\ million + 5 * P[/tex]

Subtract 2 million from both sides

[tex]19.5\ million - 2\ million= 2\ million - 2\ million + 5 * P[/tex]

[tex]19.5\ million - 2\ million= 5 * P[/tex]

[tex]17.5\ million = 5 * P[/tex]

Divide both sides by 5

[tex]\frac{17.5\ million}{5} = \frac{5 * P}{5}[/tex]

[tex]\frac{17.5\ million}{5} = P[/tex]

[tex]3.5\ million = P[/tex]

Answer:

shirts are $32 each and hats are $18 each

Step-by-step explanation:

x = shirts

y = hats

2x + 5y = 154

3x + 4y = 168

use either substitution or elimination

x = $32

y = $18

The price of each shirt is $32 while the price of each hat is $18.

let

the price of each shirt  = x

the price of each hat = y

Eva's purchase will be

Nicole's purchase will be

Combine the equation to find the price of each shirt and hat.

2x + 5y = 154

3x + 4y = 168

2x = 154 - 5y

x = 77 - 5 / 2 y

3x + 4y = 168

3(77 - 5 / 2 y) + 4y = 168

231 - 15 / 2 y + 4y  = 168

168 - 231 = - 7 /2 y

- 63 = - 7 / 2 y

cross multiply

-126 = -7y

y = 18

2x + 5(18) = 154

2x + 90 = 154

2x = 154 - 90

2x = 64

x = 64 / 2

x = 32

Price of each shirt  = $32

Answer:

D

Step-by-step explanation:

So we have the equation:

[tex]ax+by+c=0[/tex]

First, let's convert this to slope-intercept form.

Subtract ax from both sides:

[tex]by+c=-ax[/tex]

Subtract c from both sides:

[tex]by=-ax-c[/tex]

Divide everything by b:

[tex]y=-\frac{a}{b}x-\frac{c}{b}[/tex]

We are told that a>0, b<0, and c>0.

In other words, a is positive, b is negative, and c is positive.

The slope of the equation is -a/b.

Since a is positive and b is negative, we will have:

-(+)/(-).

The negatives will cancel out. Therefore, our slope will be positive.

Since our slope is positive, our line must be upwards sloping. Eliminate answers A and C.

Also, our y-intercept is:

-c/b.

c is positive and b is negative. Thus, similarly:

-(+)/(-).

Again, the negatives cancel. This means that the y-intercept must be positive.

Out of B and D, the graph that has a positive y-intercept is D.

D is our answer :)

Answer:

im not sure how the data should be interpreted but here is the distribution. It goes up by .416

Step-by-step explanation:

the average of the first 8 games is 24

the average of the 12 games is 24.416

The mean of the data of the given basketball player will increase if she scored 24, 22, 27, and 28 points in her next four games.

A mean is an arithmetic average of a set of observations. it is given by the formula,

Mean = (Sum of observations)/Number of observations

Given that the number of points scored by a basketball player in the first eight games is 15, 35, 18, 30, 25, 21, 32, and 16. Therefore, the mean of the first 8 games is,

Mean = (15 + 35 + 18 +30 + 25 + 21 + 32 + 16)/8

          = 176/8

          = 22

Now, the player scored 24, 22, 27, and 28 points in her next four games. Therefore, the mean will be,

New Mean = (15 + 35 + 18 +30 + 25 + 21 + 32 + 16 + 24 + 22 + 27 + 28)/12

                  = 277 / 12

                  = 23.0833

Hence, the mean of the data of the given basketball player will increase if she scored 24, 22, 27, and 28 points in her next four games.

We have to make sure the terms are like terms before we add them.

Like terms are terms with the same variable so we can add r's with r's, t's with t's, etc.

There are two r's and two s's so we can simplify those

12r - 4r = 8r

So, we are given that the area is:

[tex]x^3-5x^2+3x-15[/tex]

And the width is:

[tex]x^2+3[/tex]

And we want to find the length. To do so, first substitute the expressions into the equation:

[tex]x^3-5x^2+3x-15=(x^2+3)\ell[/tex]

Thus, to find the length, divide by (x²+3):

[tex]\displaystyle \ell = \frac{x^3-5x^2+3x-15}{x^2+3}[/tex]

We can factor the numerator:

[tex]x^3-5x^2+3x-15[/tex]

From the first two terms, factor out a x².

From the third and fourth terms, factor out a 3:

[tex]=x^2(x-5)+3(x-5)[/tex]

First I figured out the area of the square which is 18×18=324

Then I found out the are of the circle which is 254.47, so 324 - 254.47 = 69.53

Then there are 4 times the shaded are so divided by 4, so 69.53  ÷ 4 = 17.3825

PLEASE GIVE BRAINLIEST!

Answer:

shaded area = 17.38 cm²

Step-by-step explanation:

given:

diameter of circle = 18 cm and = side of square

π = 3.142

shaded area = ( Area of square - Area of circle ) x 1 / 4

Area of square = s² = 18² = 324 ²cm

Area of circle = π d² / 4

                       = 3.142 (18²) / 4

                       = 254.5 cm²

therefore, shaded area = ( 324 cm² - 254.5 cm² ) * 1/4

                                       = 17.38 cm²

Answer:

14 adults and 5 children

Step-by-step explanation:

Set up a system of equations, where a is the number of adults and c is the number of children:

2.5a + c = 40

a + c = 19

Multiply the bottom equation by -1 to solve by elimination:

2.5a + c = 40

-a - c = -19

1.5a = 21

a = 14

Now, plug in 14 as a  to find the number of children:

a + c = 19

14 + c = 19

c = 5

So, 14 adults and 5 children attended
