This is called a unit rate.
Answer:
Are the events A and B disjoint? Yes
Step-by-step explanation:
Disjoint events are those events that cannot occur at the same time, i.e. for events <em>X</em> and <em>Y</em> to be disjoint,
.
The event <em>A</em> is defined as the number of students whose age is at most 32.
And event <em>B</em> is defined as the number of students whose age is at least 37.
The events <em>A</em> and <em>B</em> are disjoint events.
- The sample space for event <em>A</em> consists of all the students of age group (under 21), (21 - 24), (25 - 28) and (29 - 32).
- Whereas the sample space for event <em>B</em> consists of all the students of age group (33 - 36), (37 - 40) and (Over 40).
The sample space for the intersection of these two events is:
Sample space of (<em>A</em> ∩ <em>B</em>) = 0
As there are no common terms in both the sample.
Hence proved, events <em>A </em> and <em>B</em> are disjoint.
Answer:
0.0975 or 9.75%
Step-by-step explanation:
Assuming that no engines fail simultaneously, the probability that exactly one engine fails is the probability that the first engine fails (15%) multiplied by the probability that the second engine does not fail (100% - 35%):

The probability of exactly one engine failure is 0.0975 or 9.75%
Area=1/2 times base times height
given
base=11in
height=6in
area=1/2 times 11 times 6
area=66/2 square inches
area=33 square inches
the area is 33 in²
Step 1:
Let x equal the repeating decimal you are trying to convert to a fraction
Step 2:
Examine the repeating decimal to find the repeating digit(s)
Step 3:
Place the repeating digit(s) to the left of the decimal point
Step 4:
Place the repeating digit(s) to the right of the decimal point
5) Subtract the left sides of the two equations.Then, subtract the right sides of the two equations<span>
