Answer:
To find the mean, you have to add all numbers together and divide them by the number of data points.
let me show what I mean:
The heights of the dogs are 600,470,170, 430,300.
Step-by-step explanation:
600+470+170+430+300.
1970.
Now we have to divide 1,970 by 5 ( because we are given 5 data points)
The mean is:
1970/5=394
Variance: First, arrange the data from least to greatest.
s2 = 27130
Standard Deviation: 164.71187
Answer:
-6.3
Step-by-step explanation:
7/10 X -9/1 = -63/10 = -6.3
Answer: - 49
Step-by-step explanation:
f(x) = -2x - 1
g(x) =
- 1
fg(x) = f (
- 1) , we just put in the value of g(x) , the next thing is to substitute
- 1 for the value of x in f(x) , that is
fg(x) = -2(
- 1) - 1
fg(x) = -2
+ 2 - 1
fg(x) = -2
+ 1
Therefore : fg(-5) means we will substitute -5 for x in fg(x) , that is
fg(-5) = -2 (
+ 1
fg(-5) = -2(25) + 1
fg(-5) = -50 + 1
fg(-5) = -49
