Answer: $\dfrac{1}{3}$ km per minute

Step-by-step explanation:

Given : The winner of the New York marathon ran the 8 kilometer event in 24 mins.

Then, the runners unit rate is given by :_

$\text{Runner's unit rate}=\dfrac{\text{Distance}}{\text{Time}}$

i.e. $\text{Runner's unit rate}=\dfrac{8}{24}=\dfrac{1}{3}$

Hence, the runners unit rate = $\dfrac{1}{3}$ km per minute.

A unit rate is when a rate is expressed by having 1 as the second number...

So for your problem you would want to find out how many minutes it took the runner to run 1 kilometer

To obtain the unit rate for your problem you will need to divide the numerator (24) by the denominator (8)

when you divide 24 by 8 the final answer is 3

so the unit rate is.....

the runner will run 1 kilometer in 3 minutes

also expressed as 1:3

i'm guessing this is what you wanted?
I hope this helps!

Magnitude statistics allow one to draw general conclusions about a population from information collected in a population sample.

kow [346]

inferential statistics allows for someone to draw conclusions about a population from the information collected in a population sample.

the qestion is incomplete .please read below to find the missing content

Which of the following allows for someone to draw conclusions about a population from the information collected in a population sample?

a. magnitude statistics

b. central tendency

c. inferential statistics

d. effect size

The population is the number of people living together in a place. The population of a city is the number of people living in that city. These people are called residents or residents. The population includes all individuals living in that particular area.

Population refers to the total number of organisms living in a particular area. Population helps us estimate the number of beings and know how to act accordingly. For example, knowing the exact population of a city allows us to estimate the number of resources required. Similarly, animals can do the same.

What are the best approximations of the solutions to this system?

Scilla [17]

(-1.2,-2.0) and (1.9,2.2) are the best approximations of the solutions to this system.

Option B

Step-by-step explanation:

Here, we have a graph of two functions from which we need to find the approximate value of common solutions. Let's find this:

First look at where we have intersection points, In first quadrant & in third quadrant.

At first quadrant:

Draw perpendicular lines from x-axis & y-axis from this point . After doing this we can clearly see that the perpendicular lines cut x-axis at x=1.9 and y-axis at y=2.2. So, one point is (1.9,2.2)

At Third quadrant:

Draw perpendicular lines from x-axis & y-axis from this point. After doing this we can clearly see that the perpendicular lines cut x-axis at x=-1.2 and y-axis at y= -2.0. So, other point is (-1.2,-2.0).

Simplify 6x2y3/24y2x3

mafiozo [28]

6 x² y³ / 24 x³ y²

Divide numerator
and denominator by x² : 6 y² / 24 x y²

Divide numerator
and denominator by y² : 6 / 24x

Divide numerator
and denominator by 6 :  1 / 4x
