Yes, every value in the number is increased ten times then the one before. Am easier way to understand this is to say that one extra 0 was added to the place value of 9. See it as from 10 to 100
Answer:
Yes,they do.
Step-by-step explanation:
A triangle base with sides 9,12, and 15 is a right triangle.
Answer:
Replace x with y and vice versa
Step-by-step explanation:
You have the same graph instead you write y in place of x. The horizontal one is y axis and vice versa. This is done mostly for reversed functions. like x^2 function and √x
To get the variance, start with finding the mean of your data points:
(23 + 19 + 22 + 30 + 28) / 5 = 24.4
Now take each data point and subtract the mean from it, then square that value:
23 - 24.4 = -1.4 * -1.4 = 1.96
19 - 24.4 = -5.4 * -5.4 = 29.16
22 - 24.4 = -2.4 * -2.4 = 5.76
30 - 24.4 = 5.6 * 5.6 = 31.36
28 - 24.4 = 3.6 * 3.6 = 12.96
Now get the average of those new numbers. That is your variance:
(1.96 + 29.16 + 5.76 + 31.36 + 12.96) / 5 = 16.24
The standard deviation will be the square root of the variance:
√(16.24) = 4.0299 (rounded to 4DP)
9 AND 35 OVER 100 i think
