f^-1 (x) = x/4
Step-by-step explanation:
Answer:
its the 4th one
Step-by-step explanation:
you go up by 4 and right by 3
The answer is D.
In the expression, the fraction must be larger than 1/4, yet smaller than 7/8.
It can't be A because 1/5 is smaller than 1/4. See below.
1/5 = 4/20
1/4 = 5/20
It also can't be B because 8/9 is larger than 7/8. See below.
8/9 = 64/72
7/8 = 63/72
Lastly, the answer cannot be C because 2/10 is smaller than 1/4.
1/4 = 5/20
2/10 = 4/20
Answer D works because:
10/20 = 2/4 > 1/4
10/20 = 80/160 < 140/160
here is the data set for the complete question
x: 18 21 19 21 20 21
y; 2 14 5 6 18 18
Answer:
B. 0.652
Step-by-step explanation:
x y rank of x rank of y d d²
18 2 1 1 0 0
21 14 4 4 0 0
19 5 2 2 0 0
21 6 4 3 1 1
20 18 3 5.5 -2.5 6.25
21 18 4 5.5 -1.5 2.25
∑d² = 8.5
rs = 1 - 6[∑di² + ∑m(m²-1)]/n(n²-1)
= 1 - 6[8.5 +{3(3²-10/12 + 2(2² - 1)/12}]/6(6²-1)
= 1 - 0.348
= 0.652
therefore option b is the right answer.
