Answer: The estimated value for population mean rating based on these ten sampled ratings is 7.3 .
Step-by-step explanation:
Given : A random sample of size ten produced the following ratings in the computer games rating example in the last lesson:
12, 5, 2, 4, 1, 4, 18, 10, 1, 16.
Let x denotes any value in the above data.
We know that the sample mean
is the best estimate to the population mean
.
Sample mean=
Here , n= 10
Therefore , the estimated value for population mean rating based on these ten sampled ratings= 7.3
Answer:
<em>N = 1/2x + 6</em>
Step-by-step explanation:
We know that Jane has 6 more shoes than 1/2 of what Mercedes has. We can use this information to make an equation.
<em>N (or number of shoes Jane has) is equal to 1/2x (or the number of shoes Mercedes has) plus 6.</em>
When written out we get our answer of:
<em>N + 1/2x + 6</em>
Answer:
b = 
Step-by-step explanation:
Given
a = 4b + 
- b, that is
a = 3b +
Multiply through by 3 to clear the fraction
3a = 9b + 2 ( subtract 2 from both sides )
3a - 2 = 9b ( divide both sides by 9 )
= b
48 it is counting up by odd numbers (3,5,7,9,11, 13
A is 175 B is 726 C because she don't have money number 4 It's 262627272
