Answer:
84%
Step-by-step explanation:
The empirical rule tells you that 68% of the standard normal distribution is within 1 standard deviation of the mean. The distribution is symmetrical, so the amount in the lower tail is (1 -68%)/2 = 16%.
Since the number you're interested in, 240, is one standard deviation above the mean (200 +40), the percentage of interest is the sum of the area of the central part of the distribution along with the lower tail:
68% + 16% = 84%.
Answer:
480 students want more field trips.
60 students is 10%.
Step-by-step explanation:
There are 600 students, and 80% want more field trips.
80% of 600 is 0.8*600 = 8*60 = 480 students.
480 students want more field trips.
Answer:
its 4
Step-by-step explanation:
because u divied
If you want to take a square root of a square root you will need 2 squares roots,
For example, i want the square root of the square root of 16.
I'll take it first: √16 = 4 and again, √4 = 2
So, the square root of the square root of 16 is 2.
But you can also make a root with index 4.
Because if you do 2.2.2.2 you will take 16.
