Pythagorean Theorem:

$a^{2} + b^2 = c^2$

36^2 + b^2 = 39^2

1,296 + b^2 = 1,521

b^2 = 225

b = 25

Joe organised a large wedding.

Y_Kistochka [10]

Answer:

The total number of guests that were at the wedding was 276.

Step-by-step explanation:

Let the total number of guests at the wedding be, <em>N</em>.

The meal options are:

Beef, Chicken and Vegetarian.

It is provided that:

Proportion of guests who chose beef is, $\frac{1}{3}$ .

Proportion of guests who chose chicken is, $\frac{5}{12}$ .

According to the laws of probability, the sum of the probabilities of all the events of a sample space is 1.

Then the sum of probability of guests selecting beef, chicken or vegetarian should also be 1.

Compute the proportion of guests who chose vegetarian as follows:

P (Vegetarian) = 1 - P (Beef) - P (Chicken)

$=1-\frac{1}{3}-\frac{5}{12}$

$=\frac{12-4-5}{12}$

$=\frac{3}{12}\\\\=\frac{1}{4}$

So, the proportion of guests who chose vegetarian was $\frac{1}{4}$ .

It is also provided that the number of guests who chose vegetarian was 69, i.e. $\frac{1}{4}$ of N = 69.

Compute the value of N as follows:

$\frac{1}{4}\times N=69$

$N=69\times 4$

$=276$

Thus, the total number of guests that were at the wedding was 276.
