Mathematics
1 answer:
Tasya [4]2 years ago
8 0

Answer:

s = 22t or \frac{t}{s} = \frac{1}{22}, when s is students and t is teachers.

Step-by-step explanation:

I. Given t = teacher, s = student

When 1 teacher per 22 students so...

        s = 22t

If there're 10 teachers

        s = 22(10)

           = 220 or \frac{t}{s} = \frac{1}{22}

Hope that help :)

What are the related frequencies to the nearest hundredth of the columns of the two way table?
Eddi Din [679]

Answer: The relative frequency of column A in group 1=0.75

The relative frequency of column B in group 1=0.25

The relative frequency of column A in group 2=0.56

The relative frequency of column B in group 2=0.44

Step-by-step explanation:

The relative frequency is the ration of each frequency by the total value in particular group.

For group 1 : Total =102+34=136

The relative frequency of column A in group 1=\frac{102}{136}=0.75

The relative frequency of column B in group 1=\frac{34}{136}=0.25

For group 2 : Total =18+14=32

The relative frequency of column A in group 2=\frac{18}{32}=0.5625\approx0.56

The relative frequency of column B in group 2=\frac{18}{32}=0.4375\approx0.44

What is the slope of a line that is perpendicular to the line represented by the equation 2x−5=−y?
Liula [17]

Answer:

\frac{1}{2}

Step-by-step explanation:

First, you need to get the equation into y = mx + b form, like this:

Add y to both sides to get y + 2x − 5= 0

Then subtract 2x to get y - 5 = -2x

Add 5 to get y = -2x + 5

Now we know the slope is -2, or -2/1.

A line that is perpendicular to it has a slope that is the first line's slope's opposite reciprocal. This means flip the fraction upside down and change the sign, which gives you positive 1/2.
