Answer:

Z and B are independent events because P(Z∣B) = P(Z).

Step-by-step explanation:

Z and B are independent events

When Z  and B  are independent events then

P(Z and B) = P(Z) * P(B)

P(Z∣B)= \frac{P(Z and B)}{P(B)}

P(Z∣B)= \frac{P(Z)*P(B)}{P(B)}

We cancel out P(B) on both sides

P(Z|B) = P(Z)

Thank you for posting your question here. Below is the solution:

ark worked 5 2/3 + 9 1/3 = 15 hours. 8 3/5 + 9 2/5 = 18 hours + 9 hours. 
<span>15 + 18 + 9 = 42 hours worked @ $6.55 per hour </span>
<span>40 hours regular pay and 2 hours overtime. </span>
<span>Over time is 1 1/2 X $6.55 = $9.83 per hour X 2 hours overtime worked = $19.65 in over time . </span>
<span>40 hours @ $6.55 = $262.00 + $19.65 = $281.65.Gross pay </span>

<span>Chris. </span>
<span>5 1/2 + 9 1/2 = 15 hours </span>
<span>8 4/5 + 5 1/5 = 14 hours </span>

Answer:

a) 94 degrees lower

b) -17 degrees

Step-by-step explanation:

you should draw a number line to visualize what i'm saying..

basically any number that has a greater value but is negative is obviously lower than a smaller negative value

for example: take -563 that is a lot less than -31 because its farther down the number line

okay to find the answer to question a) you need to obviously find the difference between -29 and 65 to do that you need to count the space in between -29 and 65 on a number line.

There's actually a much easier method just use your common sense and some math: so you can say the distance from 0 to 65 is … 65 and the distance from -29 to 0 is 29 so to find the total distance you add them up and you get your answer! (94)

for b) its even easier you just take the number -29 and add 12 from it to get closer to 0 so to do that you need to subtract 12 to get a smaller number but bigger value on the number line (if you draw this one out it will make sense). And the answer is... -17! I hope this made sense :)

11 because 30 - 6.5 equals 23.5 and if she can use all 23.5$ on tomato’s you divide by 2 and it equals 11.75. But she can’t go over 30 so you round it down to 11 pounds
