Answer:
4
Step-by-step explanation:
pi*r^2
just put each number where r is to find out the answer
Step-by-step explanation:
Since the first coordinates are both (0,0) it implies that the line passes through the origin.
The slope of the line is therefore 5/8
The equation:
y-0=5/8(x-0)
y=5/8x
Answer:
Sample range appears to be a biased estimator since it consistently underestimated the population range.
Step-by-step explanation:
The calculation of sample range appear to be a biased or unbiased estimator of population range is shown below:-
Sample range (x) Frequency (f) fx
9 1 9
14 1 14
15 2 30
16 1 16
17 4 68
18 2 36
19 1 19
20 3 60
21 5 105
22 2 44
23 1 23
24 2 48
25 4 100
26 4 104
27 2 54
28 4 112
29 3 87
30 1 30
31 5 155
32 2 64
Total 50 1,178
Mean sample range = ∑ fx ÷ ∑ f
= 1,178 ÷ 50
= 23.56
Therefore the sample range is not equal to population range that is
23.56 ≠ 32
Thus, Sample range appears to be biased estimator.
So, the correct option is A.
Answer:
Thanksss for the points :D
Step-by-step explanation:
You made my day lol..
1. 25% of 8$ is 2$, so dividing 16 and 2, it takes 8 weeks for 16 dollars
2. 400 is 80% of what number?, y=400x100/80
Y= 500
