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

What would be the equation to you have a part time job. You work for 3h on Friday and 6h on Saturday. You also recieve an allowa
HACTEHA [7]

Answer:

Step-by-step explanation:

So, to go about your question, we must first ask, how many hours a week is being worked?

In this problem, that is 9 hours per week.

Next, we must question how much per week is made

That is $92 per week

Finally, we must determine if the allowance is occuring many times in the week or just once.

In this problem, that is only occuring once for the week.

So, the equation we must setup is 9x +20 =92.

To solve the equation, we need to subtract 20 on both sides to isolate the variable, x.

9x+20=92

     -20     -20

Now our equation is

9x=72

Now, to finally get x by itself or to isolate x, you should divide 9 on both sides to cancel out the 9 being multiplied by the x.

<u>9x</u>=<u>72</u>

9     9

x=8 because of 72/9 is equal to 8.

I hope this helps, and I will answer any questions you have.

Rashid [163]

The Lewis family and the Perry family each used their sprinklers last summer. The water output rate for the Lewis family's sprinkler was 15 L per hour. The water output rate for the Perry family's sprinkler was 40 L per hour. The families used their sprinklers for a combined total of 65 hours, resulting in a total water output of 1850 L . How long was each sprinkler used

Answer:

Hours of use of sprinkler by Lewis family is 30 hours.

Hours of use of sprinkler by Perry family is 35 hours.

Step-by-step explanation:

Let W = hours of use by Lewis family

65 - W = hours of use by Perry family

Then;

15W + 40*(65 - W) = 1850

15W + 2600 - 40W = 1850

(15 - 40)W = 1850 - 2600

-25W = −750

W = 750/25 = 30

Therefore;

W = 30

65 - W = 65 - 30 = 35

Hence,

Hours of use by Lewis family is 30 hours.

Hours of use by Perry family is 35 hours.
