Ede4ka [16]

Answer:

a) Figure attached

b) For this case we want this probability:

P(X>16)

And we can use the complement rule:

P(X>16) = 1-P(X

And we can use the cumulative distribution function given by:

F(x)= \frac{x-a}{b-a}, a\leq X \leq b

And replacing we got:

P(X>16) =1- \frac{16-7.5}{20-7.5} = 1-0.68 = 0.32

Step-by-step explanation:

For this case we define the random variable X= depth (in centimeters) of the bioturbation layer in sediment for a certain region, and we know the distribution for X, given by:

X \sim Unif (a=7.5, b=20)

Part a

For this case we can see the figure attached.

Part b

For this case we want this probability:

P(X>16)

And we can use the complement rule:

P(X>16) = 1-P(X

And we can use the cumulative distribution function given by:

F(x)= \frac{x-a}{b-a}, a\leq X \leq b

And replacing we got:

P(X>16) =1- \frac{16-7.5}{20-7.5} = 1-0.68 = 0.32

The table shows the values of a function f(x).
QveST [7]

Answer:

The average rate of change is =-4

Step-by-step explanation:

The average rate of change from x=a to x=b of f(x) is given by;

=\frac{f(b)-f(a)}{b-a}

We want to find the average rate of change of the function represented in the table  from x=-2 to x=2.

=\frac{f(2)-f(-2)}{2--2}

From the table f(-2)=25 and f(2)=9

The average rate of change from x=-2 to x=2 is

=\frac{9-25}{2--2}

=\frac{-16}{4}

=-4
