Answer:
a) Figure attached
b) For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:
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:
Part a
For this case we can see the figure attached.
Part b
For this case we want this probability:
And we can use the complement rule:
And we can use the cumulative distribution function given by:
And replacing we got:

Answer:
$51.
Step-by-step explanation:
Interest I = PRT/100 where P = amount of the loan , R = rate and T = the times in years.
I = 340 * 15 * 1 / 100
= 5100/100
= $51.
Answer:
vertex is (4,-4) and another point is (6,0) or you could use (2,0) or many other options :)
Step-by-step explanation:
The cool thing about this question your quadratic is in factored form so your x-intercepts are easy to figure out, they are 2 and 6.
So you can plot (6,0) and (2,0).
The vertex will lie half between x=2 and x=6... so it lays at (6+2)/2=4
We just have to find the y-coordinate for when x=4.
Plug in 4 gives you (4-2)(4-6)=(2)(-2)=-4.
So the vertex is at (4,-4).
