Given the function h(x)=x^2-7x+6h(x)=x
Goryan [66]

Answer:

0 (no change)

Step-by-step explanation:

Recall that the average rate of change of a function f(x) over the interval [a,b] is equal to \frac{f(b)-f(a)}{b-a}:

\frac{h(b)-h(a)}{b-a}\\ \\\frac{h(6)-h(1)}{6-1}\\\\\frac{0-0}{5}\\ \\0

Hence, the average rate of change of the function h(x) over the interval [1,6] is 0, or no change.

There is 60% chance that it will rain today. If it rains, the probability of watching a movie is 0.5. But, if it does not rain t
agasfer [191]

Applying the given probabilities, it is found that there is a 0.42 = 42% probability of watching a movie today.

These following <em>probabilities </em>involve a movie being watched today:

  • 0.5 of 0.6(if it rains today).
  • 0.3 of 1 - 0.6 = 0.4(if it does not rain today).

Hence, adding them:

p = 0.5(0.6) + 0.3(0.4) = 0.3 + 0.12 = 0.42

0.42 = 42% probability of watching a movie today.
