1.The price of a coat was priced at $300. It went on sale after Christmas. It had a 22% discount. What was the sale price?

LekaFEV [45]

Answer:

1. $234

2. B) 6

Step-by-step explanation:

1. Since the coat is on sale for 22% off you want to do 300 times 0.22 to get 66. With this number you are going to take 300-66 to get $234.

2. The formula for the volume of a rectangular pyramid is V= lwh/3

Since I know that the total volume is 120 I know that the l times w time h has to equal 360 since its divided by 3. With the 12 and 5 I get 60. Since I know that 360/60 equals 6 I know the answer is B.

Let x be the amount of time (in minutes) that a particular San Francisco commuter must wait for a BART train. Suppose that the d

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:

$c = 20*0.9 = 18$
