The Spearman rank-order correlation coefficient, rs, is the nonparametric version of r. It converts all (x, y) pairs to their corresponding (x rank, y rank) pairs and computes the correlation between the X and Y rankings. Below are 7 randomly generated (x, y) pairs: (14,35) (24,57) (29,85) (36,83) (53,39) (91,92) (94,29)
The Spearman rank-order correlation coefficient is found to be rs = -0.32.
a. Which of the following 7 (x, y) pairs will also have rs0.32?
a. (8,31) (16,42) (20,46) (47,49) (56,58) (88,66) (97,91).
b. (8,65) (16,90) (20,41) (47,30) (56,45) (88,57) (97,48)
c. (8,6) (16,7) (20,2) (47,1) (56,3) (88,5) (97,4).
d. (1,66) (2,91) (3,42) (4,31) (5,46) (6,58) (7,49).
e. (8,1) (16,2) (20,3) (47,4) (56,5) (88,6) (97,7).
b. Any set of n (x, y) pairs can be written as (1,-), (2,--), (3,--), , (n,-) with blanks filled in with 1, 2, 3, , n in different orders corresponding to the rank of the y values You can always translate values to ranks, but can you ever translate ranks back to values?
1. Yes
2. No

the final amount you will pay is $68.04.

the tip is determined by the pre-tax amount, so we calculate the tip based on the original bill, not after we've added sales tax.

to find the tip:

we can divide 54.00 by 100 to get 1% of 54. then we multiply that by 18.

54 / 100 = .54

.54 x 18 = 9.72

tip = 9.72$

to find the tax:

we can divide 54.00 by 100 to get 1% of 54. then we can multiply that by 8 to get 8%.

54 / 100 = .54

.54 x 8 = 4.32

tax= 4.32

now we can add the tip and tax to the bill to get our total.

54 + 9.72 + 4.32 = 68.04

total: $68.04

hi how are you doing today? if you ever need just tell me

step-by-step explanation:

simplifying

5(x + -6) = 2(x + 3)

reorder the terms:

5(-6 + x) = 2(x + 3)

(-6 * 5 + x * 5) = 2(x + 3)

(-30 + 5x) = 2(x + 3)

reorder the terms:

-30 + 5x = 2(3 + x)

-30 + 5x = (3 * 2 + x * 2)

-30 + 5x = (6 + 2x)

solving

-30 + 5x = 6 + 2x

solving for variable 'x'.

move all terms containing x to the left, all other terms to the right.

add '-2x' to each side of the equation.

-30 + 5x + -2x = 6 + 2x + -2x

combine like terms: 5x + -2x = 3x

-30 + 3x = 6 + 2x + -2x

combine like terms: 2x + -2x = 0

-30 + 3x = 6 + 0

-30 + 3x = 6

add '30' to each side of the equation.

-30 + 30 + 3x = 6 + 30

combine like terms: -30 + 30 = 0

0 + 3x = 6 + 30

3x = 6 + 30

combine like terms: 6 + 30 = 36

3x = 36

divide each side by '3'.

x = 12

simplifying

x = 12

this should .
