Answer:
C. 0.12
Step-by-step explanation:
<u>Independent events</u>
The outcome of one event does not affect the outcome of the other. If A and B are independent events then the probability of both ocurring is:
P(A and B) = P(A) x P(B)
With P(A) = 0.40 and P(B) = 0.30 then
P(A and B) = 0.40 x 0.30 = 0.12
The three-day weighted moving average for the price of the stock at the end of Day 7 is 57.17.
<h3>How do we calculate a weighted moving average?</h3>
Note that since this is for the end of Day 7, it implies that the actual Day 7 Stock Price is not yet known at the time of the calculation and we need to forecast it.
Therefore, the most recent price is Day 6 Sock Price and a three-day weighted moving average for this question can be calculated as follows:
Three-day weighted moving average = ((Day 6 Sock Price * 3) + (Day 5 Sock Price * 2) + (Day 4 Sock Price * 1)) / (3 + 2 + 1)
Three-day weighted moving average = ((55.00 * 3) + (59.00 * 2) + (60.00 * 1)) / (3 + 2 + 1)
Three-day weighted moving average = 57.17

Answer:
x = -10
Step-by-step explanation:
move all the constants (numbers without variables) to one side to get
-4x = 42 - 2
-4x = 40
multiply by -1
4x = -40
divide by 4
x = -10
