15 men can do a piece of work in 80 days. If 5 more men are added, how long will it take to complete same piece of work?​
tresset_1 [31]

Answer:

Step-by-step explanation:

This is an inverse proportion.

men = k / Time         So first we need to find k

k = men * Time         Substitute values

k = 15*80

k = 1200  Notice the units are man days.

Now what happens if we increase the number of men to 20? What happens to the number of days.

20 = 1200 / time          Multiply both sides by time

20*time = 1200            Now divide by 20

time = 1200/20

Answer: time = 60 days

Are G and F mutually exclusive events? Explain. G and F are mutually exclusive because if you are not a finalist, then you canno
Alika [10]

Answer: G and F are mutually exclusive because they cannot occur together

Step-by-step explanation:

According to the definition of mutually exclusive events,

The events which can not occur together and probability of them occurring together is 0 are known as mutually exclusive events.

The first statement gives an implication that if one happens then other happens meaning they could both still happen so it is not true.

The second statement contradict the question about being mutually exclusive events.

The third statement also is a implication that if one event occurs then other does or does not occur.

The last statement is correct one that conforms with the question and obeys the definition of mutually exclusive events.
