The answer is the first data set because remember, an outlier is a number in a data set that is extremely far away from all of the other numbers.

You can easily tell which one is the outlier, the first data set's outlier is 13, because it is was placed so far away from the other data points.

We know that the first data set is correct because all of the other data sets have numbers that are clustered together.

~Hope I helped!~

Step-by-step explanation:

Imagine a triangle with two of the corner points being the points (5,5) and (8,1)

The length and width would be 3 and 4 to find the hypotenuse (distance) do

3^2+4^2=x^2

9+16=x^2

A car takes 4 hours to reach a destination traveling at a speed of 63 km/h. How long will it take to cover the same distance if

Gre4nikov [31]

Answer:

It will take 4.5hrs to cover the same distance

The constant of variation,k=252

Step by step explanation

Given that,

$speed = \frac{distance}{time}$

From the question

Time=4hr

Speed=63km

By substitution we obtain,

$63= \frac{distance}{4}$

Cross multiplying we get,

$distance=63 \times 4$

$distance=252km$

Now,

speed=56km

Distance Covered=252km

By substitution:

We obtain,

$56= \frac{252}{time}$

Cross multiply

$56\times time=252$

Divide through by 56

$time= \frac{252}{56}$

$time=4.5hrs$

From the formula,

$speed= \frac{distance}{time}$

Which means that, speed and time varies inversely.

$speed\propto \frac{1}{time}$

Let k be variation constant

This implies that

$speed = k \times \frac{1}{time}$

$k=speed \times{time}$

Taken,

Time=4hrs

speed=56km

$k=56\times4$

$k=252$

a car rent is $220 per week plus $0.25 per mile. Find the rental cost for a two week trip of 500 miles for a group of three peop

JulsSmile [24]

Here, Equation is: C = 220x + 0.25y
Where x = number of weeks
y = Distance in miles,

Now, C = 220(2) + 0.25(500)
C = 440 + 125
C = 565

In short, Your Answer would be $565

Hope this helps!

2,592+3,385 =3,385 + whar is it

amm1812

Lol... I don't know if this is a joke, but it's basically just restating the precious problem, but switching numbers. So the answer would be 2,592.
