A math teacher randomly assigns seats in the classroom to students each quarter. Each student randomly chooses their row number

out of a hat. In the classroom, there are 4 desks in each row and 27 students in your class. What is the probability that you and your 3 friends will get to sit together in the same row?

Using the combination formula, it is found that the probability that you and your 3 friends will get to sit together in the same row is given by:

p = \frac{1}{17550}.

We do not consider the order, hence the <em>combination formula</em> is used to solve this question.

<h3>What is the combination formula?</h3>

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by:

C_{n,x} = \frac{n!}{x!(n-x)!}

4 students will be taken from a set of 27, hence the number of ways they can sit is given by:

C_{27,4} = \frac{27!}{4!23!} = 17550

Only one outcome is desired, hence the probability is given by:

p = \frac{1}{17550}.

Solve each equation. Check your solution. 10z = 40
m_a_m_a [10]

Answer:

b.   z = 4

Step-by-step explanation:

Multiply both sides of the equation by 1/10. This gives ...

  (1/10)·10z = (1/10)·40

  z = 4                 simplified

_____

<em>Check</em>

Putting 4 where z is in the original equation should give us a true algebraic expresion. It does.

  10·4 = 40        true

The diagonals of parallelogram JKLM below intersect at point (2, 5). If K is located at (8, 7), what are the coordinates of poin
Slav-nsk [51]

Answer:

<h3>A (-4,3)</h3>

Step-by-step explanation:

THe formula for calculating midpoint is expressed as;

M(X, Y) = {(x1+x2/2), y1+y2/2}

Given

Midpoint = (2, 5)

K = (8, 7)

Required

Coordinate of M

X = x1+x2/2

2 = 8+x2/2

4 = 8+x2

x2 = 4-8

x2 = -4

Similarly;

Y = y1+y2/2

5 = 7+y2/2

10 = 7+y2

y2 = 10-7

y2 = 3

Hence the coordidates of M is at (-4,3)
