Answer:
80 units
Step-by-step explanation:
KN = MN
9x - 5 = 7x + 7
2x = 12
x = 6
KM = 2KL
KM = 2(6x + 4)
KM = 12x + 8
KM = 12(6) + 8
KM = 80
Two perpendicular lines have slopes that are negative reciprocals of each other, that is, if one slope is a/b, the other is -b/a
the first line 5x+2y=20, 2y=-5x +20, y=-5/2 x+10, the slope is -5/2, so the perpendicular line's slope is 2/5
the equation in point-slope form is (y-2)=(2/5)(x-5)
in slope-intercept form: y=(2/5)x
in standard form: 2x-5y=0
Answer:
y-3=-4(x+2)
Step-by-step explanation:
y-y1=m(x-x1)
y-3=-4(x-(-2))
y-3=-4(x+2)
Answer:
2050
Step-by-step explanation:
<u>Year 2010</u>
The number of people over 65 years of age =32 million
Total population = 307 million.
P(meeting a person over 65 at random in 2010)

<u>Year 2050</u>
The number of people over 65 years of age =88 million
Total population = 434 million.
P(meeting a person over 65 at random in 2050)

Conclusion: Since 0.2028 is greater than 0.1042, the chances of meeting a person over 65 at random will be greater in 2050
