The answer is both sets of statistics give the same information:
First, find the mean: 2 • 5 = 10, 3 • 4 = 12, and 10 • 1 = 10
10 + 12 + 10 = 32
Ten dots altogether : 32 ÷ 10 = 3.2
Mean = 3.2
Second, find the median: 2, 2, 2, 2, 2, 3, 3, 3, 3, 10
2, 2, 2, 2, <em>2, 3,</em> 3, 3, 3, 10
2 + 3 = 5
5 / 2 = 2.5
Median - 2.5

Answer:
47
Step-by-step explanation:
follow Pemdas order of operations.
8 + (9 + 23) − 9 + 8 × 6 ÷ 3 =
8 + (32) - 9 + 8 x 6 ÷ 3
8 + (32) - 9 + 16
add and subtract the rest and u get 47
The slope of the given line is 5/4. The slope of a line perpendicular to the given line is the negative reciprocal of 5/4, or -4/5.
Using the point-slope form,
y - 5 = (-4/5)(x - 10).
This is the desired new line.
Note that mult. both sides by 5 removes the fractions:
5y - 25 = -4(x - 10), or 5y - 25 = -4x + 40.
Solving this for y: 5y = 25 - 4x + 40, or 5y = -4x + 65
Then y = (-4/5)x + 13 (answer)
Answer:
x= 15
Step-by-step explanation:
Since this is an isosceles triangle, the other angle is also 5x-6
The sum of the angles of a triangle is 180
42+ 5x-6 + 5x-6 = 180
Combine like terms
10x+30 =180
Subtract 30 from each side
10x+30-30 = 180-30
10x = 150
Divide by 10
10x/10 = 150/10
x= 15
