Answer: A. The statement is false. The pivot positions in a matrix are determined completely by the positions of the leading entries in the nonzero rows of any echelon form obtained from the matrix.

Step-by-step explanation:

A pivot position is simply referred to as a location in a matrix row echelon form that's reduced which equates to leading 1.

From the question, we are given a statement that the pivot positions in a matrix depend on whether row interchanges are used in the row reduction process

It should be noted that the statement is false as the pivot positions in a matrix are determined completely by the positions of the leading entries in the nonzero rows of any echelon form obtained from the matrix.

Sally is shopping for diapers and sees a box with 216 diapers for \$39.98 and a box with 88 diapers for \$24.99 . Which option h
Mekhanik [1.2K]
The first step is to find out the value of one diaper for each equation

39.98/216 = 0.18
Therefore one diaper is for 0.18 cents

24.99/88 = 0.28
Therefore one diaper is for 0.28 cents

At the end the first deal is better

Solve for the value of x. Show each of your steps. 7y=8x - 14 ; y= 6
svetlana [45]
When y=6, then in equation 7y=8x-14 we write 6 instead of y:
7×6=8x-14
42=8x -14
8x-14=42 (now we add 14 to both sides of equation)
8x=56 (now we divide by 8 both sides of equation)
x=7

Answer: x=7

Currency exchange rates are constantly fluctuating. How might this affect the currency exchange plans of a traveler who plans to
Bingel [31]

Answer:

Currency exchange rates fluctuations pose budget uncertainty risk for future travellers. A solution to this is Forward Exchange rate markets.

Step-by-step explanation:

Currency Exchange rate is the rate at which two currencies can be exchanged for each other, it is the price of one currency in terms of other.

The currency exchange rates are dynamic, fluctuating based on demand & supply of currencies in foreign exchange markets. This uncertainty in currency rates is not good for foreign travellers, for making later plans. It might disturb their entire allotted budget.

So, they should purchase foreign exchange on Forward Exchange Rate. This rate depicts agreement for exchange of currencies, at pre-determined exchange rate, at a specific date. Buying foreign exchange from Forward markets will protect travellers from Forex volatilities.

The daily number of customers at a dry cleaner during one week are 80, 75, 68, 74, 63, 81, 79, and 68.
Flauer [41]
I think the correct answer would be both the mean and median are appropriate measures of center. Since the given data set is ordinal and is not skewed that much. Also the values of such would be close with each other. Hope this answers the question.
