1/2 or .5
Because there is two tests happening and that is the denominator, and if the probability of only one working it was be 1/2
Answer:
1. No
2. Yes
3. Yes
4. Yes
Step-by-step explanation:
In 1. the difference between each term is not constant.(it goes up by, 2, 4, 6)
2. The terms increase by the same amount(it all goes up by 3)
3. The terms decrease by the same amount(it all goes down by 5)
4. The terms increase by the same amount(it all goes up by 6)
Multiply the factors together. You should get the original expression.
For example, if we are to factor
2x^2 + 4x
we would factor as
2x(x + 2).
Check this by multiplying back in
2x*x + 2x*2 = 2x^2 + 4x
which is what we started with, so we know we are correct.
A rule of polygons is that the sum<span> of the </span>exterior angles<span> always equals 360 degrees, but lets prove this for a regular </span>octagon<span> (8-sides). First we must figure out what </span>each<span>of the interior </span>angles<span> equal. To do this we use the </span>formula<span>: ((n-2)*180)/n where n is the number of sides of the polygon</span>
Range: largest number minus the smallest number
39 - 19 = 20
your range is 20
Mean: add all of the numbers and divide by the amount of numbers there are.
26+19+23+39+31+34+23+25= 220
220/8 = 27.5
your mean is 27.5
hope this helps
