Any value? you could use 0 or 1 or 2. All three of these are a group of many that would wokr. Any would work!
The area of the room would be 380.25 feet
78 / 4 = 19.5 (you do this to figure out how long each side of the room is)
19.5 * 19.5 = 380.25 feet (length times width equals area. Each side of the room is 19.5 feet so you would multiply 19.5 by 19.5)
The question is incomplete. Here is the complete question.
Nite Time Inn has a toll-free telephone number so that customers can call at any time to make a reservation. A typical call takes about 4 minutes to complete, and the time required follows an exponential distribution. find the probability that a call takes
a) 3 minutes or less
b) 4 minutes of less
c) 5 minutes of less
d) Longer than 5 minutes
e) Longer than 7 minutes
Answer: a) P(X<3) = 0.882
b) P(X<4) = 0.908
c) P(X<5) = 0.928
d) P(X>5) = 0.286
e) P(X>7) = 0.174
Step-by-step explanation: <u>Exponential</u> <u>distribution</u> is related with teh amount of time until some specific event happens.
If X is a continuous random variable, probability is calculated as:
in which:
m is decay parameter, given by:
For the Nite Time Inn calls:
m = 0.25
(a) P(X<3)
P(X < 3) = 0.882
<u>The probability the call takes less than 3 minutes is 0.882.</u>
(b) P(X<4)
P(X < 4) = 0.908
<u>The probability the call takes less tahn 4 minutes is 0.908.</u>
(c) P(X<5)
P(X < 5) = 0.928
<u>The probability of calls taking less than 5 minutes is 0.928.</u>
(d) P(X>5)
Knowing that the sum of probabilities of less than and more than has to equal 1:
P(X<x) + P(X>x) = 1
P(X>x) = 1 - P(PX<x)
For P(X>5):
P(X > 5) = 0.286
<u>The probability of calls taking more than 5 minutes is 0.286.</u>
(e) P(X>7)
P(X > 7) = 0.174
<u>The probability of calls taking more than 7 minutes is 0.174.</u>
Answer:
scalene
Step-by-step explanation:
It would be scalene because all of the sides have a different length
Breaking Apart Strategy is an easy way to find multiplication, even though those are difficult ones. This is a great strategy for breaking apart harder multiplication problems, so the result you get is the same as if you are multiplying the original equation.
<span>
For example, suppose you want to get this multiplication:
</span>
<span>
So eight times seven is a tricky one sometimes. Maybe we forget this multiplication so let's break it apart. Therefore, let's break apart seven, that is:
</span>
<span>
This is true because five and two makes seven. Therefore, the new equation is:
</span>
<span>
Applying distributive property:
</span>
<span>
So:
</span>
<span>As you can see the multiplication was obtained in a easy way.
