Answer:
128
Step-by-step explanation:
32 x 4 = 128
o
32 + 32 + 32 + 32 = 128
The sampling error if the grade point averages for 10 randomly selected students from a class of 125 students has a mean of x =2. is A. -0.7.
Given:
Random number=10
mean of x=2
population=125
mean of p=2.7
Using this formula
Sampling error=x− μ
Where:
x= sample mean=2
μ=population mean=2.7
Let plug in the formula
Sampling error=2-2.7
Sampling error=-0.7
Inconclusion the sampling error is A.-0.7.

<u>Answer:</u>
<u>Step-by-step explanation:</u>
<u>To subtract fractions, we must check if the denominators of both fractions are the same.</u>
- 2/5 - 1/7
- => 2 x 7/5 x 7 - 1 x 5/7 x 5
- => 14/35 - 5/35
<u>Now, let's subtract for the result.</u>
Hence, <u>Option B is correct.</u>

Answer:
3rd one and last one
Step-by-step explanation:
First one:
4 × 3 × 4 = 48
Second one:
1 × 2 × 4 = 8
Third one:
2 × 3 × 5 = 30
Fourth one:
2 × 5 × 4 = 40
Fifth one:
2 × 2 × 4 = 16
Process of elimination:
The first one is itself greater than 47 units³, so this is definitely not one of the two;
A combination of the fourth prism and the smallest one as the second will give a volume of 48 units³, which is greater than 47 so this prism is also not one of the two we are looking for;
This leaves the second, third and fifth;
The second and third sum to 38, which is less than 42 so it is not the correct combination;
Similarly, the second and last gives only 24 so it is not the correct combination;
This leaves the only remaining option of the third and fifth;
30 + 16 = 46, which confirms this to be the correct combination.
