Answer:
(0,6)
(1,4)
Step-by-step explanation:
(0,6)
1. Plug in 0 for x and solve to see if 6 results for y
y = -2(0) + 6
0 + 6 = 6
y = 6
When 0 is plugged in for x, y equals 6 which makes (0,6) a solution.
(1,4)
1. Plug in 1 for x and solve to see if 4 results for y
y = -2(1) + 6
-2 + 6 = 4
y = 4
When 1 is plugged in for x, y equals 4 which makes (1,4) a solution.
(-2,-2)
1. Plug in -2 for x and solve to see if -2 results for y
y = -2(-2) + 6
4 + 6 = 10
10 ≠ -2
When -2 is plugged in for x, y does not equal -2 which means (-2,-2) is not a solution.
Perimeter is all outside lengths added up. So 8+8=16. 15+15=30
16+30= 46.
Isolate the x. Add 1/6 to both sides
x - 1/6 (+1/6) = 8 (+1/6)
x = 8 1/6

Answer:
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
Step-by-step explanation:
A) Mean life expectancy of women
from the attached table
mean life expectancy of women = ∑fx / ∑f
∑fx = 1523
∑f = 20
mean = 1523 / 20 = 76.15
The line graph shows a negatively skewed distribution
B) Mean life expectancy of Men
from the attached table
mean life expectancy of Men = ∑fx / ∑f
∑fx = 1432
∑f = 20
mean = 1432 / 20 = 71.6
<em>conclusion : Life expectancy of women > Life expectancy of men </em>
