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

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

=> $P(Z) = \frac{1}{156}$

=> $P(Z) = 0.0064$

If a bus driver leaves her first stop by 7:00 a.m., her route will take less than 37 minutes. If she leaves after 7:00 a.m., she

mr Goodwill [35]

What we know about this situation that either she will take less than 37 minutes:

r<37

or she will take more than 42 minutes

r>42

so it means that she cannot take between 37 and 42 minutes.

The best way to write it is:
37>r v r>42

where "v" means "or" in mathematical notation

Olivia has made a pyramid model for her history project at school. The pyramid model has a square base. Each triangular side of

Tresset [83]

Answer:

278 square centimeters

Step-by-step explanation:

You need to use the Pythagorean Theorm. If you're pyramid is a perfect square, then to the middle the length is 5. Because 10/2 is 5. You then use the Pythagorean Theorm (a^2 + b^2 =c^2) to find the side length of the traingle. When you square the hypotenuse and subtract the bottom leg sqaured, you are left with 3.46274054 after square rooting it. (c^2-a^2=b^2) Plug these into the equation for a right, rectangluar pyramid. You then get 277.9, rounded, is 278.

Hope this helps!
