Answer:
the first number is 3.4 and the second number is 1
Step-by-step explanation:
The computation of the two numbers is shown below:
Let us assume the first number be x
And, the second number be y
Now the equations are
5x + 4y = 21
And,
5x + 9y = 16
Now subtract equation 2 from equation 1
-5y = -5
y = 1
And, the x is
5x + 4 = 21
5x = 17
x = 3.4
Hence, the first number is 3.4 and the second number is 1
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
