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:

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

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

The area of a rectangle is 144cm squared.if the length is 16cm. What's the perimeter?

andreev551 [17]

Answer:

Step-by-step explanation:

rectangle area = 144 cm

Formula: A= L*H

The give the length which is 16

144 = 16*H

Since they gave u the area instead of the height, work backwards

144/16 = 16/16 *H

9 = H

Now you have the length and height

Length: 16

Height: 9

Perimeter is when you add up all the sides

The top and bottom of the rectangle is the length which is 16 so

16 + 16 = 32

The left and right side of the rectangle is the height which is 9 so

9 + 9 = 18

Now add then both

32 + 18 = 50

So the perimeter of the rectangle is 50

Hope this helped!
