They are parallel when the slopes are the same
example:
y=2x+3
y=2x-5
Answer:
see below
Step-by-step explanation:
6(y(2)−4)
=(6)(y(2)+−4)
=(6)(y(2))+(6)(−4)
=12y−24
6(y2−4)
=(6)(y2+−4)
=(6)(y2)+(6)(−4)
=6y2−24
Answer:
C) Both sets have an interquartile range of 27.
Step-by-step explanation:
Sorted data
Set 1: 65, 66, 77, 79, 81, 93, 104, 105
Set 2: 1, 29, 56, 59, 60, 67, 72, 74
Median position: (8+1)/2 = 4.5th value
Ranges:
Set 1: 105 - 65 = 40
Set 2: 74 - 1 = 73
Medians:
Set 1: (79+81)/2 = 80
Set 2: (59+60)/2 = 59.5
IQR:
Set 1: (93+104)/2 - (66+77)/2
= 27
Set 2: (67+72)/2 - (29+56)/2
= 27
In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents the constant ratio of the circumference of any circle to its diameter, approximately equal to 3.14159.
1/3(n + 4) - 6 = -2 <== ur equation
1/3n + 4/3 - 6 = -2 ...multiply by 3
n + 4 - 18 = - 6
n - 14 = -6
n = -6 + 14
n = 8 <== ur number
