The board of an internet start up company has sixteen members. if one person is in charge of research and one is in charge of ma
Brilliant_brown [7]

The number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members is <u>240 ways</u>. Computed using permutations.

The permutation is the way of choosing a set of objects from a larger set of objects in a specific sequence.

If we are choosing r number of objects, from n number of objects in a specific sequence, then we follow permutation, and it is given as:

nPr = n!{(n - r)!}.

In the question, we are asked to find the number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members.

Since the position is to be chosen in a specific order, we will follow permutation.

The number of positions to be chosen (r) = 2.

The number of members (n) = 16.

Thus, the number of ways is given as:

nPr = n!{(n - r)!},

or, 16P2 = 16!{(16 - 2)!},

or, 16P2 = 16!/14! = 15*16 = 240.

Thus, the number of ways in which the position of one person in charge of research and one person in charge of marketing can be chosen from the board of 16 members is <u>240 ways</u>. Computed using permutations.

Alicia walks 4 miles in 1 hour and can speed walk 5 miles in 1 hour. What percent of Alicia's average speed walking rate is her
RSB [31]

Answer:

The % Alicia speed walking is 125 % of average walking

Step-by-step explanation:

Given as :

Distance cover by Alicia while walking = 4 miles

Time taken                                               = 1 hour

So, Speed of Alicia while walking = \frac{Distance}{Time}

Or,                                            S 1  =  \frac{4 miles}{1 hour}

I.e                                              S 1  =  4 mph

And

Distance cover by Alicia while speed walk  = 5 miles

Time Taken                                                      = 1 hour

So, Speed of Alicia while speed walking = \frac{Distance}{Time}

Or,                                            S 2  =  \frac{5 miles}{1 hour}

I.e                                              S 2  =  5 mph

Or,   % Rate = \frac{5}{4} ×100 = 125

Hence The % Alicia speed walking is 125 % of average walking  Answer
