((frac{x}{y}) + rw = z) Solve for x in the equation above.

A. x=y(z-rw)

B. x=rw(y-z)

C. x=w(z+ry)

D. x=rwy-z

Answer Explanation:

The question requires us we make x the subject of the formula.

First, we subtract rw to both sides of the equation

Multiply both sides by y

Thus, the formula for finding the value of x is y(z-rw).

Therefore, the Correct Answer is A.

A. 86

B. 69

C. 44

D. 80

Answer Explanation

Explanation: the median of a data set is the element that is found on the middle position.

To find median, organize the given data from the smallest to largest.

44, 56, 69, 76, 80, 86, 92, 93, 96

Now, the number of elements in the date set is 9, which is an odd number. The median falls in the position

(N+1)/2=(9+1)/2=10/2=5.

The number that falls in the 5th position is 80. Thus, 80 is the median of the data.
Q #3: A pharmaceutical company’s stock price was $20.33 on Monday. On Tuesday, the price went up $0.35. On Wednesday, the price decreased from Tuesday’s price by $1.05. On Thursday, the price went up $0.95 from Wednesday’s price. Which of the following was the final price on Thursday?

A. $20.68

B. $19.63

C. $20.63

D. $20.58

Answer Explanation

Thursday’s stock price is found by determining the price of the stock on Tuesday and Wednesday.

Stock price on Monday= $20.33

Stock price on Tuesday= $(20.33+0.35)=$20.68

Stock price on Wednesday =$(20.68-1.05)=$19.63

Stock price on Thursday = $(19.63+0.95)=$20.58

Therefore, the price of the stock on Thursday was $20.58
