Answer: 25

Step-by-step explanation:

Given : Water stations will be placed every 600 meters of a fifteen kilometer race.

i.e. Total length of the race track = 15 kilometers

Since 1 km= 1000 m

Then , Total length of the race track = 15000 kilometers

Distance required to place water stations = 600 meters

Then , the number of water stations will be needed is given by :-

=\dfrac{15000}{600}=25

Hence, the number of water stations will be needed = 25

1km=1000metres
15km=15000 metres 
15000/600=25
25-1=24 (minus the last one)

hope this helps :)

Answer:

Answer:

P(A) = 0.39

Step-by-step explanation:

We are given;

P(W|A) = 0.7

P(W|A^c ) = 0.3

We are told that 60% of the respondents said they voted for A. Thus;

P(A|W) = 60% = 0.6

Now, using the principle of drawing lots, we can be able to find the probability of the event that they are willing to participate in the exit poll which is P(W).

Thus;

P(W) = [P(W|A) × P(A)] +[P(W∣A^c) × P(A^c)]

Now, P(A^c) can be expressed as 1 - P(A)

Thus, we now have;

P(W) = [P(W|A) × P(A)] + [P(W∣A^c) × (1 - P(A)]

Plugging in the relevant values gives;

P(W) = 0.7P(A) + 0.3(1 - P(A))

P(W) = 0.7P(A) + 0.3 - 0.3P(A)

P(W) = 0.3 + 0.4P(A)

Now,using Baye's theorem, we can find an expression for P(A|W)

Thus;

P(A|W) = [P(A ∩ W)]/P(W)

This can be further expressed as;

P(A|W) = [P(A) × P(W|A)]/P(W)

Plugging in relevant values, we have;

0.6 = 0.7P(A)/(0.3 + 0.4P(A))

Cross multiply to get;

0.6(0.3 + 0.4P(A)) = 0.7P(A)

0.18 + 0.24P(A) = 0.7P(A)

0.18 = 0.7P(A) - 0.24P(A)

0.46P(A) = 0.18

P(A) = 0.18/0.46

P(A) = 0.39

32,000 and 42,000. I know this because the question states "Two Thousands." 32,000 and 42,000 are both two thousands because 32 and 42 both end with 2's because of the "Two" in "Two Thousand."
