Answer:

Option Y is correct.

Step-by-step explanation:

We are given the table representing the relation between new students and returning students for difference classes.

It is required to form the relative frequency table for the given situation.

So, relative frequency table is obtained by dividing the valued by the total number of values in the data set.

Thus, we will get the relative frequency table by dividing the given table values by 500.

Hence, we will get the following table,

New Students Returning Students Total

10th 0.01 0.34 0.35

11th 0.006 0.324 0.33

12th 0.004 0.316 0.32

Total 0.02 0.98 1

Thus, option Y is correct.

4. A river tour boat is going down a stream to a park for lunch and then back up. It is a 60-mile round trip. On

DiKsa [7]

Answer:

The speed of the boat in still water is 10 miles / hour

Step-by-step explanation:

The trip there, and the trip back are the same -- 30 miles

Let the rate of the boat = x

Let the rate of the water = y

30 = 2*(x + y)

30 = 6*(x - y)

Divide the top equation by 2

Divide the bottom equation by 6

15 = x + y

5 = x - y Add the equations together.

20 = 2x Divide by 2

20/2 = x

x = 10

Emily leaves her house at exactly 8:25 a.m. to bike to her school, which is 3.42 miles away. When she passes the post office, wh

mafiozo [28]

First, let's find out the number of minutes Emily has to get to school. From 8:25 to 8:50, there are 25 minutes.

Next, let's find out the number of minutes before Emily looks at her watch. From 8:25 to 8:28.50, there are 3.5 minutes.

Now let's calculate Emily's speed in miles per minute. To do so, divide the distance traveled by the time it took:

$\frac{0.75}{3.5}$ miles/minute

Now let's calculate how far Emily can travel in 25 minutes going this speed. To do so, we multiply her speed by the time traveled:

$\frac{0.75(25)}{3.5} =5.357$ miles

5.357 miles is greater than 3.42 miles, so yes, Emily will make it to school on time.
