Answer:
5196
Step-by-step explanation:
So it's 5040+(-156)
We have to find the absolute value
|-156|=156
5040+156=5196
Let's write down what we know:
a=50+b
b=30+c
After one hour:
(a+50)*2=-70+3*(c+50)
let's eliminate the brackets:
2a+100=-70+3c+150
2a+100=+3c+80
which is:
2a=-20+3c
substituting from a=50+b:
100+2b=-20+3c
substituting from b=30+c
100+2(30+c)=-20+3c
100+60+2c=-20+3c
160+20=3c-2c
180=c.
So we know that c is equal to 40, then b will be b=30+c
b=30+180=210.
So B had 210 miles initially.
U just need to count how many numbers are in ur data.
There is one 1....so the one dot over the 1 is correct
There are four 2's....so the 4 dots over the 2 is correct
There is one 3....so 1 dot over 3 is correct
There are three 4's...but u only have 2 dots over the 4 when there should be 3....so ur answer is going to be 4 <==
I believe that the answer to the question provided above is that standard deviation in definition is how scattered the data are, thus it will determinr possible outliers.

The distance between the two given points (28,-12) and (28,6) is 18.
<h3>What is the distance between the two given points?</h3>
Formula for the distance between two points is expressed as;
D = √( ( x₂ - x₁)² + ( y₂ - y₁ )²
Given the data in the question;
For point (28,-12)
For point (28,6)
We plug in the values into the formula above.
D = √( ( 28 - 28)² + ( 6 - (-12) )²
D = √( ( 0 )² + ( 6 + 12 )²
D = √( 0 + ( 18 )² )
D = √( 0 + 324 )
D = √( 324 )
D = 18
Therefore, the distance between the two given points (28,-12) and (28,6) is 18.
