7 is not equal to the others
using the laws of exponents
/ = 1 / =
=
Apart from 7 the other 3 all equal
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.
Answer:
+112 +11v
Step-by-step explanation:
-7(-10-6)+1v+10v =
(-10-6) = -16
-7(-16) +1v +10v =
+112 +1v +10v =
+112 +11v
Question 13-18 & 22-27 will all be answered the same way, so i will walk you through question 13: (6,4) y=3x-2
(x,y)=(6,4)
now that we know the first number in the parenthesis is the x value and the second number in the parenthesis is the y value we can plug it into the equation. (x=6,y=4)
4=3x-2 (add two to each side)
4+2=3x
6=3x (divide 3 from each side)
x=2
---------------
y=3(6)-2
y=18-2
y=16
-------------------
answer: (2,16)
now apply the same principles to the other problems!!! hope this helped!!!
(10/n +6) -3
10/2+6-3
5+6-3
11-3
8
Hope this helped!
