Answer:
5
Step-by-step explanation:
Given that :
Miles ridden in Tuesday = 10
Miles ridden on Wednesday = 20
Sample size, n = 2
Mean :
(10 + 20) / 2
= 30 /2
= 15
Mean absolute deviation :
(|10 - 15| + |20 - 15|) / 2
(5 + 5) / 2
10 / 2
= 5
Answer= 285000
How to= the number you are dividing by has a decimal move the decimal point all the way to the right counting the number of places you’ve moved it to. Then move the decimal point in the number you’re dividing the same number of places to the right
If you sketch the triangle you will see it is a right triangle with B being the vertex for the right angle. the orthocenter is the intercept of the three altitudes. for a right triangle, the orthocenter is the vertex where the right angle is.so the answer for this question is (-4,5)
The unit of measurement that is used for the water in the swimming pool is 2.3×10⁴ gallons.
<h3>What is the Units conversion?</h3>
Unit conversion is a way of converting some common units into another without changing their real value. for, example, 1 centimetre is equal to 10 mm,
though the real measurement is still the same the units and numerical values have been changed.
As it is given that the volume of the pool or the amount of water that is in the pool is equal to 2.3×10⁴ units.
We know that an average swimming pool has a volume of water that is in gallons, therefore, the unit of water that will be filled in the swimming pool will be equal to 2.3×10⁴ gallons.
Hence, the unit of measurement that is used for the water in the swimming pool is 2.3×10⁴ gallons.

We will have to use the distance formula in order to determine the lengths of each side of the triangle.
Distance formula:

Let's calculate AB first:
A (1, 7) and B (-2, 2)
A: x1 = 1 and y1 = 7
B: x2 = -2 and y2 = 2
so



AB =

or (rounded to the nearest tenth) ≈ 5.8
Now let's do BC:
B: x1 = -2 and y1 = 2
C: x2 = 4 and y2 = 2
So


BC =

or 6
Now let's do CA
C: x1 = 4 and y1 = 2
A: x2 = 1 and y2 = 7
So



CA =

or (rounded to the nearest tenth) ≈ 5.8
So let's recap:
AB ≈ 5.8
BC = 6
CA ≈ 5.8
So AB and AC are the same length while BC is .2 units longer which means this is an
isosceles triangle.
