Convert 5 7/8 to an improper fraction. Use this rule: a b/c = ac + b/c

5 × 8 + 7/8 × 2 4/5 ÷ 7

Simplify 5 × 8 to 40

40 + 7/8 × 2 4/5 ÷ 7

Simplify 40 + 7 to 47

47/8 × 2 4/5 ÷ 7

Convert 2 4/5 to an improper fraction using the same rule from the previous step.

47/8 × 2 × 5 + 4/5 ÷ 7

Simplify 2 × 5 to 10

47/8 × 10 + 4/5 ÷ 7

Simplify 10 + 4 to 14

47/8 × 14/5 ÷ 7

Use this rule: a ÷ b/c = a × c/b

47/8 × 14/5 × 1/7

Proceed to use this rule: a/b × c/d = ac/bd

658/8 × 5 × 7

Simplify 8 × 5 × 7 to 280

658/280

Simplify

47/20

Convert to mixed fraction

2\frac{7}{20}

We know that an outlier is a point that stands out as compared to the rest of the data points.

Clearly from the scatter plot based on the given points in the question we get tat Point A is an outlier because it attains a different value as compared to the rest of the data points.

Hence, the outlier is:

Point A.

Tan(x-y) if cscx=13/5 and coty=4/3
ehidna [41]

Answer:

tan(x-y) = -16/63

Step-by-step explanation

Tan(x-y) if cscx=13/5 and coty=4/3

Given

coty = 4

1/tany = 4/3

Cross multiply

tan y = 3/4

Also since cscx = 13/5

1/sinx = 13/5

sinx = 5/13

Since sinx = opp/hyp

opp = 5

hyp = 13

Get the adjacent

hyp² = opp²+adj²

13² = 5²+adj²

adj² = 13² - 5²

adj² = 169 - 25

adj² = 144

adj = 12

cosx = adj/hyp

cosx = 12/13

tanx = sinx/cosx

tanx = (5/13)/(12/13)

tanx = 5/13 * 13/12

tan x = 5/12

tan(x-y) = tanx - tany/1+tanxtany

tan(x-y) = (5/12 - 3/4)/1+(5/12)(3/4)

tan(x-y) = (5-9/12)/1+5/16

tan(x-y) = -4/12/(21/16)

tan(x-y) = -1/3 * 16/21

tan(x-y) = -16/63
