11.84 rounded to the nearest whole number is 12. It’s simple add all c,d, and f percents. Then turn the percent into a decimal by dividing by 100, and multiply that decimal by the students , which is 32.
As described in statistics the mean standard deviation of the headway is 0.890
what is the statistics ?
The study of statistics is the field that deals with the gathering, structuring, analyzing, interpreting, and presenting of data. In order to apply statistics to a problem in science, business, or society, it is customary to start with a statistical population or a statistical model that will be investigated.
solution:
P(0.995 ≤ x ≤ 1.445) = F(1.445) - F is the given mean value (0.995).
The distribution's cdf is
f(x) = { (1 - 1/x⁶ , x > 1) (0. x ≤ 1)
F(1.445) = 1 - (1/(1.445)⁶)
F(0.995) = 0
Now, using the values of F(1.445) and F(0.995) in P( 0.995 ≤ x ≤ 1.445) to get F(1.445) - F(0.995):
P( 0.995 ≤ x ≤ 1.445)
=1 - (1/(1.445)⁶) - 0
=0.890
Therefore the mean value of standard deviation is 0.890

Answer:
399
Step-by-step explanation:
To find the population in a future year, use the formula:

where A is the amount, p is the starting population, r is 5% or 0.05, and t is the number of years.
Since the population is increasing it is addition. Here we are finding A. Substitute P =380, r=0.05 and t=1.
