Answer:
- Keisha’s experimental probability is 1/50.
- When the inventory is 4000 clocks, the prediction is that 3920 clocks will work.
- Keisha will have more than 97% of the products working.
Step-by-step explanation:
These are three prediction that Keisha can make based on the report that said 6 of 300 clocks tested weren't working.
Base on that information, Keisha can calculate an experimental probability, dividing <em>clocks that don't work properly </em>by <em>the total amount of clocks</em><em>:</em>
<em></em>
Therefore, the probability of success is 100% - 2% = 98%.
This means that Keisha has a probability of having 98% of all clocks functioning properly. So, she can make the prediction:<em> from 4000 clocks, 3920 will work. </em>Also, she can predict that she will actually have more than 97% working, because the experimental probability is higher than that.
Answer:
is the area expressed as function of x,
and x: >0, <50 is the domain of the function.
Step-by-step explanation:
Draw an appropriate figure and then express the area of the rectangle as a function of x.
We know that the diagonal of a rectangle inscribed in a circle, will be equal to the diameter of the circle. 50 feet
let w = the width of the rectangle
therefore
recall
Area = x*w
replace w
is the area expressed as function of x
b)state the domain of the function
x: >0, <50
Answer:
Step-by-step explanation:
The answer uses the unit circle and that sine and cosecant are reciprocals.
The first choice doesn't even fit the criteria that is between
and
(inclusive of both endpoints) because of the
.
Let's check the second choice.
.
which means
which is not greater than 1.
So we can eliminate second choice.
Let's look at the third.
which means
.
isn't defined because
.
So we are eliminating 3rd choice now.
Let's look at the fourth choice.
which means
and not greater than 1.
I was looking at the rows as if they were choices.
Let me break up my choices.
So we said doesn't work because it is not included in the inequality
.
How about ? This leads to
which doesn't exist because
.
So neither of the first two choices on the first row.
Let's look at the second row again.
We said worked but not
Let's look at the choices on the third row.
We said worked but not
Let's look at at the last choice.
We said it gave something less than 1 so this choice doesn't work.

Step-by-step explanation:
From the question we are told that
The average number of passengers that arrive per minute is
The average number of check that can be carried out in one minute is
Generally the probability that a passenger will have to wait before being checked for weapons is mathematically represented as
