Answer:
32
Step-by-step explanation:
the median in a data set is the middle number. first, you are going to want to order the numbers in numerical order.
this is what it would look like.
16, 21, 28, 30, 34, 45, 58, 60
(basically how it is in the problem lol)
since there's an even number of numbers in the set, you have to take the mean of the two middle numbers. in this case, the two middle numbers are 30 and 34.
you take the mean of numbers by adding them, and then dividing them based on the number of numbers. (sorry if that doesn't make sense, just look down ehe)
(30+34)/2
we divide by two because there are two numbers.
(30+34)/2
(64)/2

if this didn't make sense - sorry - but you can watch this video: https://www.khanacademy.org/math/cc-sixth-grade-math/cc-6th-data-statistics/mean-and-median/v/mean-median-and-mode
it's a short 3 minute video :))
hope this helped!!
Answer:
Step One
Calculate the area of both the skating area and the spectator area.
Area = L * W
L = 4x
W = 4x
Area = 4x * 4x
Area = 16x^2
Step Two.
Find the radius of the semicircle. R = radius
From the diagram
R = The full length - the length given in the red shaded area.
R = 4x - 2x
R = 2x
Step Three
Find the area of the semicircle.
Area of a full circle = pi R^2
Area of a 1/2 circle =
Area of a 1/2 circle =
Area of a 1/2 circle =
Notice that the 2 in the denominator cancels in part with the 4 in the numerator.
Step Four
Find the area of the shaded area
Area of the shaded Area = Whole Area - Area of the Semi Circle.
Area of the shaded Area = 16x² -
The answer is the upper right corner choice I think
Answer:
non-linear
Step-by-step explanation:
Linear functions can only have powers of 1 for the x and y terms and the terms must not be multiplied.
The function y =2x^2-4 has a power of 2 on the x so it is not linear. It is parabolic.
No its not polygons dont cross lines
If I'm correct line segment, parallel lines, and Circle.
