abruzzese [7]

Answer:

40320 different ways

Step-by-step explanation:

That problem is a permutation one

We have eight people to occupy one position in a team, without any constraint at all

Total number of events = P(8)

P (8) = 8!

P (8) = 8*7*6*5*4*3*2*1

P (8) = 40320 different ways

Q2. In a camp food was enough for 400 people for 23 days. If 60 more people joined the camp, find the number of days the food wi

victus00 [196]

Answer:

Q2)

We have food for 400 people, and it will last for 23 days.

Then we have an inverse relation, where the number of days decreases as the number of people increases, this means that we have a relationship like:

23 days = K/400 people.

Then we get:

(23 days)*(400 people) = K = 9200 days*people.

Now if we increase the number of people by 60, we get.

people = 460

Then the number of days that this will last is:

D = (9200 days*people)/460 people = 20 days.

The food will last for 20 days.

Q3) We have a proportional relationship (y = k*x) such that y = 40 when x = 200, then we get:

40 = k*200

With this, we can find the value of k

40/200 = k = 0.2

Then the proportional relationship is:

y = 0.2*x

a) We need to replace x by 15.

y = 0.2*15 = 3

y = 3

b) We need to replace y by 8.

8 = 0.2*x

8/0.2 = x = 40

x = 40

Q3) y is inversely proportional to x (y = k/x), and y = 8 when x = 30.

Then we get:

8 = k/30

Then the value of k is:

8*30 = k = 240

then the relationship is:

y = 240/x

a) we need to replace x by 4

y = 240/4 = 60

y = 60

b) we need to replace y by 360

360 = 240/x

360*x = 240

x = 240/360 = 0.666...

x = 0.666...

Find the median the first and third quartiles the interquartile range and my outliers for set of data 81,69,90,79,59,125,95,116,

JulsSmile [24]

Answer:

Step-by-step explanation:

Find the median of the first and third quartiles

81, 69 ,90, 79, 59, 125, 95, 116, 183, 97, 92, 50, 122, 55, 92

50, 55, 59, 69, 79, 81, 90, <u> 92,</u> 92, 95, 97, 116, 122, 125, 183.

The first quartile: 50, 55, 59, 69, 79, 81, 90: median of the first quartile is 69

The third quartile: <u>92, 95, 97, 116, 122, 125, 183</u>: median of the third quartile is 116.

The interquartile range is the difference between the median of both the first and third quartile: which is 116 - 69 = 47.

There are no outliers in this set of data
