the mean weight of 100 students in a certain class is 71kg the mean weight of boys is 65kg and that of girls is 75kg what is the number of boys and girls​

Answers

Answer:

There are 60 girls and 40 boys in the class.

Step-by-step explanation:

Given that the mean weight of 100 students in a certain class is 71kg, while the mean weight of boys is 65kg and that of girls is 75kg, to determine what is the number of boys and girls the following calculation must be performed:

1 x 75 + 0 x 65 + 75

0.9 x 75 + 0.1 x 65 = 74

0.8 x 75 + 0.2 x 65 = 73

0.7 x 75 + 0.3 x 65 = 72

0.6 x 75 + 0.4 x 65 = 71

Thus, there are 60 girls and 40 boys in the class.

Step-by-step explanation:

If 25 percent of a square is shaded, that means that the rest of the square is not shaded. We want an answer that we can add to 25 to get 100. So this means that 75% of the square is not shaded.

Answer:

Step-by-step explanation:

rectangle = 16x4=64

two triangles 1/2(8)(7)=28 each

64+28+28=120

Answer:

88

Step-by-step explanation:

Starting off with 16x4, which isolates the triangle and makes it a little bit easier, you'd get 64, which is the rectangle's area, (I got the 4 from the middle piece). That leaves you with the triangle, which I did 3x8 for, which is 24, usually with triangles you would divide that answer in half because a triangle is only half of the actual area, but since they're two identical triangles, it wasn't necessary.

Write an equation of the line that passes through the points (−6,20) and (0, 8).

Answers

Answer:

y = -2x + 8

Step-by-step explanation:

(−6, 20) and (0, 8)

First you want to find the slope of the line that passes through these points. To find the slope of the line, we use the slope formula: (y₂ - y₁) / (x₂ - x₁)

Plug in these values:

(8 - 20) / (0 - (-6))

Simplify the parentheses.

= (-12) / (6)

Simplify the fraction.

-12/6

= -2

This is your slope. Plug this value into the standard slope-intercept equation of y = mx + b.

y = -2x + b

To find b, we want to plug in a value that we know is on this line: in this case, I will use the second point (0, 8). Plug in the x and y values into the x and y of the standard equation.

8 = -2(0) + b

To find b, multiply the slope and the input of x(0)

8 = 0 + b

b = 8

Plug this into your standard equation.

y = -2x + 8

This is your equation.

Check this by plugging in the other point you have not checked yet (-6, 20).

y = -2x + 8

20 = -2(-6) + 8

20 = 12 + 8

20 = 20

Your equation is correct.

Hope this helps!

What is the boundary line for the linear inequality 4x + 2y < 18?

Answers

Answer:

The boundary line of the inequality is intersecting the x-axis at 4.5.

The given inequality is 4x + 2y < 18.

What is the boundary line for linear inequality?

A linear inequality divides the coordinate plane into two halves by a boundary line where one half represents the solutions of the inequality. The boundary line is dashed for > and < and solid for ≤ and ≥. The half-plane that is a solution to the inequality is usually shaded.

Graph the inequality by finding the boundary line, and then shading the appropriate area.

Now, 4x + 2y < 18 can be written as y<−2x+9.

The boundary line of the inequality is given below.

The boundary line of the inequality is intersecting the x-axis at 4.5.
