Give two different ratios with the description of a ratio relationship using the following information there are 15 male teachers in the school that 35 female teachers in the school

Answers

Two different ratio are;

Male teacher : Female teacher = 3 : 7

Male teacher : Teacher = 3 : 10

Here,

Number of male teachers = 15

Number of female teacher = 35

We have to find the two different ratio.

What is Ratio?

A ratio is a comparison of two similar quantities obtained by dividing one quantity by the other.

Now,

Number of male teachers = 15

Number of female teacher = 35

Hence, Number of total teacher = 15 + 35 = 50

So, Ratio of Male teacher to Female teacher = 15 : 35 = 3 : 7

And, Ratio of Male teacher to Teacher = 15 : 50 = 3 : 10

Therefore, Two different ratio are;

1. Male teacher : Female teacher = 3 : 7

2. Male teacher : Teacher = 3 : 10

The test scores of a geometry class are given below.90, 75, 72, 88, 85
The teacher wants to find the variance for the class population. What is the value of the numerator of the calculation of the variance?

Answers

Variance is the difference of the number from the mean of the group of numbers then square it and find the average. In this case, we need to find the mean first. 90 + 75 + 72 + 88 + 85 = 410/5 = 82 . Now we must get the difference of each from the mean.
90 - 82 = 8
75 - 82 = -7
72 - 82 = -10
88 - 82 = 6
85 - 82 = 3
Next is to find the average of the square of the numbers.
(8^2) + (-7^2) + (-10^2) + (6^2) + (3^2) is
64 + 49 + 100 + 36 + 6 = 255. Next step is to simply divide it by 5. The numerator in calculating the variance is the sum of the square of the numbers which is 255.

258

After a cannonball is fired into frictionless space, the amount of force needed to keep it going equals A zero, since no force is necessary to keep it moving.
B twice the force with which it was fired.
C one half the force with which it was fired.
D the same amount of force with which it was fired.
E one quarter the force with which it was fired.

Answers

Answer:

A zero, since no force is necessary to keep it moving

Step-by-step explanation:

Since, the space is friction less, the force exerted by the gun will be enough to keep the ball going. There will not be any depreciation in the initial force. Hence, the ball continues to move forward without any impediment.

Hence, the correct answer is

A zero, since no force is necessary to keep it moving
