Answer:
Step-by-step explanation:
Variability refers to how spread out a group of data is. Data sets with similar values are said to have little variability, while data sets that have values that are spread out have high variability.
55. B
56. F
57. B
58. 2 x 7 = 14 for the steps and top, 2 x 3 = 6 for the back, 2 x 4 = 8 for the bottom, ( ( 3 x 2 ) + 3 ) x 2 = 18 for the two sides.
Altogether, the surface area is:
= 14 + 6 + 8 + 18 = 46 units²
59. I
60. D
Answer:
60
Step-by-step explanation:
The part where y resides is an equilateral triangle. That means that all the angles are equal (along with all the sides). Remember that y is in a triangle.
So the three angles of the triangle = 180/3 = 60
That means that y = 60
Answer:
S: 24x - 72
S and T are not equivalent for any value of x
Step-by-step explanation:
S: 4(6x-18) = 4 * 6x - 4 * 18 = 24x - 72
S and T are not equivalent for any value of x, x+1 S: 24 - 72 = - 48 T: 24 - 18 = 6
denoting or relating to a value or quantity lying at the midpoint of a frequency distribution of observed values or quantities, such that there is an equal probability of falling above or below it.
Put them in order, ( 70, 71, 72, 72 ,77)
There is an odd number of numbers so the median is the middle.
(70,71,72,72,77)
72 is in the median to the number list.
