larisa [96]

Answer:

a) P(X

P(X>14) = 1-P(X

b) P(7< X

c) We want to find a value c who satisfy this condition:

P(x

And using the cumulative distribution function we have this:

P(x

And solving for c we got:

c = 20*0.9 = 18

Step-by-step explanation:

For this case we define the random variable X as he amount of time (in minutes) that a particular San Francisco commuter must wait for a BART train, and we know that the distribution for X is given by:

X \sim Unif (a=0, b =20)

Part a

We want this probability:

P(X

And for this case we can use the cumulative distribution function given by:

F(x) = \frac{x-a}{b-a} = \frac{x-0}{20-0}= \frac{x}{20}

And using the cumulative distribution function we got:

P(X

For the probability P(X>14) if we use the cumulative distribution function and the complement rule we got:

P(X>14) = 1-P(X

Part b

We want this probability:

P(7< X

And using the cdf we got:

P(7< X

Part c

We want to find a value c who satisfy this condition:

P(x

And using the cumulative distribution function we have this:

P(x

And solving for c we got:

c = 20*0.9 = 18

John had $500<br> Anna has $400<br> Peter had $700<br> Who has the most?
vladimir2022 [97]

Answer:

Peter has the most

Step-by-step explanation:

Peter has the most amount of the money of the three of them.

From the question, we see that John had only $500 while Anna has $400 and Peter had $700. Which means, of all the three of them; John, Anna and Peter, Peter had the most because he had $700 the greatest amount of the three of them, which is followed by John who had $500, the greater and Anna had the least of it, $400.

Arranging from the Person who had the most of money, we have Peter with $700, John with $500 and lastly, Anna with $400.

weqwewe [10]
Peprendicular lines have slopes that multiply to get -1

y=mx+b
m=slope

2x+y=4
minus 2x
y=-2x+4
slope is -2

-2 times what=-1
what=-1/-2
what=1/2

the slope is 1/2
