Answer:
3/2 =x
Step-by-step explanation:
These two angles are interior angles. They add up to 180 degrees
20x+5 = 24x-1
Subtract 20x from each side
20x-20x+5 = 24x-20x-1
5 = 4x-1
Add 1 to each side
5+1 =4x-1+1
6 =4x
Divide by 4
6/4 = 4x/4
3/2 =x
Mean= is the summation of the maximum temperatures ÷ the numbers of times the temperatures where recorded
standard deviation= is a number used to tell how measurements for a group are spread out from the average (mean), or expected value.
A low standard deviation means that most of the numbers are very close to the average.
A high standard deviation means that the numbers are spread out.
Variance= is a way to measure how far a set of numbers is spread out.
A variance of zero indicates that all of the data values are identical. All non-zero variances are positive.
A small variance indicates that the data points tend to be very close to the mean, and to each other.
A high variance indicates that the data points are very spread out from the mean, and from one another.
X equals x because x is theoretically x the letter
8 x (3^2/4^2)
=4.5

Answer:
(7, ∞)
Step-by-step explanation:
Because x does not equal 7 as well, brackets won't be used here.
Because x can be any number greater than 7, this means the domain includes positive ∞.
