Given the following list of numbers:

1 answer:

6 0

Start by writing them in ascending order

7, 8, 9, 9, 10, 11, 11, 12, 14, 15, 15, 16, 19

The median (middle number) is the second 11. So look at the first half of the numbers (7, 8, 9, 9, 10, 11) and find the middle number there. Since there are 6 numbers, you average the middle two. Conveniently, they are both 9, so that is Q1. 25% of your numbers are below this mark, and 75% of your numbers are above this mark.

Let me know if you have any questions.

Ruby red paint costs $0.50 per square inch. A ball is painted ruby red and costs $100.00 to paint. What is the diameter of the b

8090 [49]

The diameter can be obtained by the formula A = pi*r^2

First, multiply 0.50 * 100 to obtain the area of the ball, then simplify and solve for the radius. Doubling the radius would yield the diameter. This is shown below:

Area of the ball = 0.50 * 100 = 50 in^2
<span>A = pi*r^2
</span>50 = (3.14)*r^2
r = 3.99 = approx. 4
diameter = 2r
Diameter = 8 inches.

Among the choices, the correct answer is C. 8.0 in.

2nd question this is still confusing even after getting the formula

Check the picture below.

so the figure is really just 3 rectangles and two triangles.

simply get the area of all 5, sum them up, and that's the area of the figure.

recall that area of a triangle A = ½bh.
