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.

Answer:
x = 1
y = -2
Step-by-step explanation:
5x - 2y = 9 -----------(I)
2x + 7y = -12 --------------(II)
Multiply (I) by 7 35x - 14y = 63
Multiply (II) by 2 4x + 14y = - 24 {Now add and thus y will be eliminated}
39x = 39
x = 39/39
x = 1
Plugin x = 1 in equation(I)
5*1 - 2y = 9
5 -2y = 9
-2y = 9 -5
-2y = 4
y = 4/-2
y = -2

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.

What is the boundary line for the linear inequality 4x + 2y < 18?
Answers
Answer:
Simplifying
x = 4.5 + -0.5y
Step-by-step explanation:
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.
