Samantha has $600 to spend at a bicycle store for some new gear and biking outfits.

Mathematics
1 answer:
Brut [27]3 years ago
4 0

We want to find an inequality that says how many outfits Samantha could buy.

The solution is x ≤ 2

We know that she has $600 to spend.

She already spent:

  • $392.25 in her bicycle
  • 3 bicycle reflectors for $7.01 each, so the total is: 3*$7.01 = $21.03
  • $34.96 in a pair of gloves.

The total amount she already spent is:

$392.25 + $21.03 + $34.96 = $448.24

The <u>amount of money that she has left</u> is:

$600 -  $448.24 = $151.76

Ok, now we know that each outfit costs $75.88

So the price of x of these will be x times $75.88

price = $75.88*x

This must be equal or smaller than the amount of money that she has left:

$75.88*x ≤ $151.76

x ≤ $151.76/$75.88 = 2

x ≤ 2

This is the inequality that represents the number of outfits that she can buy.

Ten weeks of data on the Commodity Futures Index are as follows.
IgorLugansk [536]

The analysis of time series is a process by which a set of observations in a time series is analyzed.

Part a: The time series plot is constructed both in de$mo$ and excel sheet.

b. The data appear to follow a horizontal pattern.

Part b: The trial and error is used to find the value of exponential smoothing coefficient that results in MSE= 0.009 which is less than 0.01.

The MSE in the first table is calculated using the average of the two previous years.

The MSE in the second table is calculated using the moving average

The MSE in the third table is calculated by using ∝= 0.4 and the value of alpha changes to different values as shown in the cell U20, V20 and W20.

The MSE is the mean squared error.

We find the error by subtracting <u><em>forecast</em></u> data from the <em><u>actual</u></em> data.

The forecasted data may be average of 2 years , moving average of 3 years or adding the multiplied chosen value of alpha with the actual data and the multiplied value of 1- ∝ with the forecasted value of data.

The error is then squared.

The squared error is then averaged which gives the MSE.

The values of ∝= 0.400641005, 0.40319659, 0.400641001 may give the best MSE values.
