The sampling distribution is illustrated below.
<h3>How to illustrate the sampling?</h3>
Based on the information given, the population is illustrated as 1, 4, 7. The sample without replacement will be:
<u>Sample Mean</u>
1 and 4. 2.5
1 and 7. 4
4 and 7. 5.5
The population mean will be:
= (1 + 4 + 7)/3
= 4
The sample mean is an unbiased estimator of the population mean.
The sampling with replacement illustrates that the mean will be:
= 36/9 = 4
Also, when n = 3, the number of samples will be:
= 3³ = 27

Answer:
23.15 an hour
Step-by-step explanation:
I will assume it is 2.5% interest rate over 2 years and not per year. If this isn’t the case then let me know.
-
-
Well $1250 divided by 100 = $12.50
This is 1%-
-
-
To make 2.5% we do-> $12.50 x 2.5= $31.25
This makes our interest rate $31.25
-
-
-
-
To get our total amount.....
$1250 + $31.25 = $1281.25
Answer: Only 21:72:87
Explanation: We know that the side lengths are not simply 7, 24, and 29, as the sum of these is only 60.
Therefore, we need to find the scale factor they were multiplied by to have side lengths with a sum of 180.
We can use 7x+24x+29x=180.
This becomes 60x=180 and the scale factor is x=3.
7*3=21, 24*3=72, and 29*3=87.
Answer:
Nephew receive 1500.00
Older niece receive 1000.00
Younger niece receive 500.00
Step-by-step explanation:
Let assume a variable x,y,z for the niece, older niece and the nephew respectively.
Y= 2x (Twice the younger niece)
Z= x + y. (Sum of the two nieces)
Since y = 2x
Z = x+2x
Z= 3x
Therefore:
X = 1x
Y = 2x
Z = 3x
So the will will be shared among them in the ratio
Nephew : older niece : younger niece
3 : 2 : 1
Nephew. 3/6 x 3000 = 1500.00
Older niece 2/6 x 3000 = 1000.00
Younger niece 1/6 x 3000 = 500.00
