Answer: Yes, No Yes, No

Answer:

Mean = average or the sum of all numbers divided by how many numbers there are.

2 + 2 + 8 + 10 + 15 + 30 + 36 + 40 + 50 + 51 = 244

244/10 = 24.4

Answer:

24.4

Step-by-step explanation:

Add all numbers together To get 244

Then divide by the number of numbers given (10)

244÷10 = 24.4

Answer:

12

Step-by-step explanation:

Make 6 a reciprocal which would be 1/6 then change the division sign to multiplication so 1/6 x 1/2 will be 12

Step-by-step explanation:

y=5x-5

y= -4x+22

1- use y=5x-5 solve for y (here you don't really have to do anything)

       This stays the same, Therefore y = 5x-5

2- you will substitute y=5x-5 for y in y= -4x+22. The problem should now look like this:

               5x-5= -4x+22

now, with the equation above you will solve for x-

5x-5= -4x+22         (add 4x to both sides)

9x-5= 22               (add 5 to both sides)

9x=27                   (divide by 9)

x=3

Now that you Know that x=3 you can substitute x=3 for x in y=5x-5. The problem should look like this:

                                                    y= 5(3)-5

Now with the equation above you can solve for y

y= 5(3)-5              (multiply 5 by 3)

y= 15-5                 (subtract)

y=10

Now you have your answers X=3  Y=10

Answer:

5.4

Step-by-step explanation:

To find the distance between two points, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex], plug them into the following equation:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\d=\sqrt{(-3-(-8))^2+(-4-(-6))^2}[/tex]

Two negatives make a positive

[tex]d=\sqrt{(-3+8)^2+(-4+6)^2}\\d=\sqrt{(5)^2+(2)^2}\\d=\sqrt{25+4}\\d=\sqrt{29}\\d=5.4[/tex]

Therefore, the distance between the two points rounded to the nearest tenth is 5.4.

I hope this helps!

Answer:

7/18

Step-by-step explanation:

7 students received a score greater than 65, out of a total of 18 students

The probability of picking a student who scored above 65 is 1/3 when one of these students is chosen at random.

To calculate the probability of picking a student who scored above 65, we need to determine the number of students who scored above 65 and divide it by the total number of students.

Looking at the given marks:

46, 65, 54, 57, 62, 73, 73, 47, 69, 48, 63, 68, 55, 48, 58, 71, 76, 70

We can see that the marks above 65 are: 73, 73, 69, 68, 76, 70 (a total of 6 marks).

Now, let's calculate the probability:

Probability = Number of favorable outcomes / Total number of outcomes

Number of favorable outcomes (students who scored above 65) = 6

Total number of outcomes (total number of students) = 18

Probability = 6 / 18

Simplifying the fraction:

Probability = 1 / 3

Therefore, the probability of picking a student who scored above 65 is 1/3.

Y= 15 - 1.5x

Answer:

1

Step-by-step explanation:

Given the equation y=1+6x, the y-intercept occurs at x = 0

Substitute

y = 1 + 6(0)

y = 1+0

Y = 1

Hence the y-intercept of the equation is 1

Answer:

AB=10

AB=7.2

Step-by-step explanation:

AB= √{(9-1)²+(8-2)²} = √{8²+6²}=√{64+36}=√100 =10

AB= √{(6-2)²+(2-8)²} = √{4²+(-6)²}=√{16+36}=√52 =7.2

The distance between points A(1, 2) and B(9,8) is 10 and the distance between points A(2, 6) and B(8, 2) is 7.2.

A coordinate plane is a plane in which a set of two number lines are represented, horizontal line is called x-axis and vertical line is called y-axis.

In the first coordinate plane,

The coordinate of point A is (1, 2) and coordinate of point B is (9,8),

To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]

Thd distance between A(1, 2) and B(9,8),

AB= [tex]\sqrt{{(9-1)^2+(8-2)^2}}[/tex] = [tex]\sqrt{{8^2+6^2}}[/tex]=[tex]\sqrt{{64+36}}[/tex]=[tex]\sqrt{100}[/tex] =10

In the second coordinate plane,

The coordinate of point A is (2, 6) and coordinate of point B is (8, 2),

To find distance, use distance formula between two points (x₁, y₁) and (x₂, y₂) is [tex]\sqrt{(x_2 - x_1)^2+ (y_2 -y_1)^2)}[/tex]

The distance between A(2, 6) and B(8, 2),

AB= [tex]\sqrt{{(8-2)^2+(2-6)^2} }[/tex]= [tex]\sqrt{6^2+(-4)^2}}[/tex]=[tex]\sqrt{{36+16}}[/tex]=[tex]\sqrt{52}[/tex] =7.2
