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:
10 ≤ x - 4
Step-by-step explanation:
Volume= π·R²·H
π is Pi, approximately 3.142
R is the radius of the circular end of the cylinder
H is height of the cylinder
C more than 5 as an algebraic expression c>5
Answer:
there cannot be any solution of the given linear equation.
Step-by-step explanation:
i) the linear equation of 18x +
= 6(3x + 25)
ii) transforming the equation to a simpler form we get
18x +
= 18x + 150 which implies that
= 150 which is not true.
iii) therefore there cannot be any solution of the given linear equation.
