VI) You finally purchased a backup oxygen tank needed for the base which originally cost

Bond [772]

Answer:

a) $32,000

b) 9/25

c) 36%

Step-by-step explanation:

Hello!

A) How much did you save?

Let's see. In order to find the savings, we must subtract the new price from the original.

50,000 - 18,000 = 32,000

You saved $32,000 (a pretty good deal!)

B) What fraction of the original price was this?

To find the fraction, we must divide the new price from the original.

18,000/50,000
9,000/25,000 => SImplify
9/25 => Simplify

It's 9 twenty-fifths of the original price.

C) What fraction of the original price was this?

Convert the fraction to percent

9/25
9*4/25*4 => Denominator of 100
36/100
36%

The 18 faculty members in a college math department range in age from 32 to 68. A stem plot follows: The first and third quartil

valentina_108 [34]

Answer:

$Q_{1}=39, \:and\: Q_{3}=58$

Step-by-step explanation:

1) This Stem and Leaf plot works like a Histogram. Completing the question, check below the Stem plot. Look the data out of the Stem plot and within (in the graph below)

32, 34 , 38 , 39 , 39 , 40 , 43 , 45 , 46 , 49 , 53 , 54 , 57 , 58 , 59 , 59 , 63 , 68

2) Notice how the first digit is on the Stem column (check below)

3) To find the first and Third Quartiles

Let's use the formulas to find the position, then the value. As it follows:

$Q_3=\frac{3}{4}(n+1) \Rightarrow Q_3=\frac{3}{4}(18+1) Q_3=14.25 \approx14th =58$

$Q_1=\frac{(n+1)}{4} \Rightarrow Q_1=4.75 th \approx Q_1 =5th =39$
