Kitty [74]

Answer:

P(Alive\ or\ Aliens) = 26\%

Step-by-step explanation:

Given

P(Alive) = 20\%

P(Aliens) = 10\%

P(Alive\ and\ Aliens) = 4\%

Required

Determine P(Alive\ or\ Aliens)

From laws of probabilities:

P(A\ or\ B) = P(A) + P(B) - P(A\ and\ B)

In this case:

P(Alive\ or\ Aliens) = P(Alive) + P(Aliens) - P(Alive\ and\ Aliens)

P(Alive\ or\ Aliens) = 20\% + 10\% - 4\%

P(Alive\ or\ Aliens) = 26\%

Find the average rate of change for f(x)=x^2-3x-10 from x=-5 to x=-10
worty [1.4K]

Answer:

-18  

Step-by-step explanation:

f(x) = x² - 3x -10

f(-10) = (-10)² – 3(-10) – 10

f(-10) = 100 + 30 - 10

f(-10) = 120

f(-5) = (-5)² – 3(-5) – 10

f(-5) = 25 + 15 - 10

f(-5) = 30

=====

The <em>average rate of change</em> is the slope m of the straight line joining the two points.

m = (y₂ - y₁)/(x₂ - x₁)

m = (30 - 120)/(-5 – (-10))

m = -90/(-5+10)

m = -90/5

m = -18
