Question

17/40 of the people who attempt to climb a certain mountain actually reach the summit. if 320 people attempt the​ climb, how many are expected to reach the​ summit?

Answer 1

To find out how many people are expected to reach the summit, we need to multiply the total number of people attempting the climb (320) by the fraction that successfully reach the summit (17/40).

Expected number of people reaching the summit = (320) * (17/40)
Expected number of people reaching the summit = 8.5 * 8
Expected number of people reaching the summit = 68

Therefore, it is expected that 68 people will reach the summit.

Answer 2

wrong

Answer 3

I apologize for the incorrect response earlier. Let's calculate it correctly this time.

To find out how many people are expected to reach the summit, we need to multiply the total number of people attempting the climb (320) by the fraction that successfully reach the summit (17/40).

Expected number of people reaching the summit = (320) * (17/40)

To simplify the calculation, we can first divide both the numerator and denominator of the fraction (17/40) by their greatest common divisor, which is 1 in this case:

Expected number of people reaching the summit = (320) * (17/40) = (17 * 320)/(40 * 1)

Now, let's calculate the numerator:
17 * 320 = 5440

And the denominator:
40 * 1 = 40

Finally, we divide the numerator by the denominator:
Expected number of people reaching the summit = 5440/40 = 136

Therefore, it is expected that 136 people will reach the summit.
