It is estimated that only
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?
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.
To find out how many people are expected to reach the summit, you can follow these steps:
Step 1: Find the fraction of people who reach the summit.
Given that only 17/40 of the people who attempt the climb make it, the fraction of the people who reach the summit is 17/40.
Step 2: Calculate the number of people who reach the summit.
Multiply the fraction of people who reach the summit (17/40) by the total number of people attempting the climb (320).
(17/40) * 320 = 136
Therefore, it is expected that 136 people will reach the summit.
To find out how many people are expected to reach the summit, we need to multiply the total number of people attempting the climb by the fraction of people who are successful.
First, let's calculate the fraction of people who reach the summit:
17/40
Then, let's multiply this fraction by the total number of people attempting the climb:
17/40 * 320
To simplify the fraction, we can divide both the numerator and the denominator by their greatest common divisor, which is 1 in this case:
(17 ÷ 1) / (40 ÷ 1) * 320
Simplifying the fraction, we get:
17/40 * 320 = (17 * 320) / 40
Now, let's calculate the numerator:
17 * 320 = 5440
Dividing the numerator by the denominator, we get:
5440 / 40 = 136
Therefore, it is expected that 136 people will reach the summit.
wrong
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.
