If x + 4y = 6 and you subst. -x+3 for y, you get    x + 4(-x+3) = 6.

Then x - 4x + 12 = 6, or -3x = -6, or x = 2.  Since y = -x+3, here y = -(2)+3 = 1.

Thus, the solution to this system of linear equations is (2,1).

The age distribution of students at a community college is given below. Age (years) Number of students (f) Under 21 2890 21-24 2
Soloha48 [4]

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, P(X\cap Y)=0.

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.
