She work a total of 7.5 average hours per day.
The probability of obtaining a head or tail in tossing a coin is modeled by the binomial distribution.
The probability of obtaining heads (success) is p = 1/2.
In n tosses, the expected statistical parameters are
m = np, the mean
σ = √[np(1-p)]
In 72 tosses of the coin, the standard deviation for the number of heads obtained is
σ = √[72*(0.5)*(0.5)]
= 4.243
Answer: 4.243
Answer:
k is 16 so now u would plug it in.
Step-by-step explanation:
3 is 65 and 9 is 65 because they are alternate interior angles
18x10=180
24x10=240
24x10=240
26x18=468
24x18=432
Add all together = 1560
15. 47 divided by 3 is 15.7 but students don’t come in decimals. So there are 15 students who got 3 cookies each, with 2 cookies left over.
