A 5-column table has 4 rows. The first column has entries A, B, C, Total. The second column is labeled X with entries 10, 110, 60, 180. The third column is labeled Y with entries 80, 44, 59, 183. The fourth column is labeled Z with entries 61, 126, 110, 297. The fifth column is labeled Total with entries 151, 280, 229, 660.
Which statement is true about whether Z and B are independent events?

a. Z and B are independent events because P(Z∣B) = P(Z).
b. Z and B are independent events because P(Z∣B) = P(B).
c. Z and B are not independent events because P(Z∣B) ≠ P(Z).
d. Z and B are not independent events because P(Z∣B) ≠ P(B).

the least common denominatore of 7 and 2 is 9

step-by-step explanation:

7+2=9

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93
