Answer: A) Mean

You use the median as the center of the boxplot. The first and third quartiles (Q1 and Q3) make up the left and right edges of the box. The min and max are the furthest points on the left and right side of each whisker. The mean is not used at all. With outliers, the mean is skewed. If you have any outliers then its best to use the median instead.

Find the sum of the zeros in the following equation: (2x-1)(x+8)(2x-4)(x-1)

lara [203]

Answer:

$-9\frac{1}{2}$

Step-by-step explanation:

$2x+1=0$

$2x=-1$

$x=-\frac{1}{2}$

$x+8=0$

$x=-8$

$2x-4=0$

$2x=4$

$x=2$

$x-1=0$

$x=1$

$1+2-8-\frac{1}{2}$

$=-1-8\frac{1}{2}$

$=-9\frac{1}{2}$

Sum of fractions $=-9\frac{1}{2}$

(Very easy) Find the volume. Round to the nearest tenth if necessary.

Pavel [41]

Answer:

410.5 yards cubed

Step-by-step explanation:

Volume of a cone is 1/3Bh

h is the height of the cone

B is the area of the base, which is a circle, so use πr^2 to find area of the circle

The radius is 7, so:

π7^2

π49(8)(1/3) = 410.5

The line plot below shows the weight of each of 15 ostrich eggs . What is the total weight of the 3 heaviest eggs

erica [24]

Answer:

D). 6 3/4

Step-by-step explanation:

Given,

The three eggs with the heaviest weights are;

$2\frac{1}{2}$ ounces

$2\frac{1}{4}$ ounces, &

2 ounces

To find,

The total weight of the three heaviest eggs = $2\frac{1}{2}$ ounces + $2\frac{1}{4}$ ounces + 2 ounces

= 5/2 + 9/4 + 2/1

Taking the L.C.M. of 2, 4, and 1,

= 10/4 + 9/4 + 8/4

= (10 + 9 + 8)/4

= 27/4 or 6 3/4
