Answer:

11 4-passenger cars

Step-by-step explanation:

let 'x' represent the number of 4-passenger cars,then 'x-3' represent the number of 6-passenger cars.

92=4x+6(x-3)

92=4x+6x-18

92=10x-18

92+18=10x

110=10x

x=110/10

x=11

Therefore there are 11 4-passenger cars

Answer:

Step-by-step explanation:

The sum of the angles is 90

2x + x = 90

3x = 90

x = 30

the angle ABC is 2x, so it means that is the double of x, so it is 60 degrees

Answer:

The probability is $P(Z) = 0.0064$

Step-by-step explanation:

From the question we are told that

The number of members is n = 15

Generally the number of ways of selecting two member from the fifteen members is mathematically represented as

$K = ^{n}C_2 * 2!$

Here C stands for combination hence we will be making use of the combination functionality in our calculator

$K = ^{15}C_2 * 2 * 1$

=> $K = 78 * 2 * 1$

=> $K = 156$

Gnerally the number of outcome that matches the outcome required by the committee(Which is reselecting the member who where the chairman and vice chairman of the board ) is m = 1

Generally the probability of randomly selecting the two members who currently hold the positions of chairman and vice chairman and assigning them to their current positions is mathematically represented as

$P(Z) = \frac{m}{K}$
