Answer:
5.2, 4.94; 500 repetitions should be closer to the population mean
Step-by-step explanation:
A. Mean of 50 repetitions
B. Mean of 500 repetitions
500 repetitions should be closer to the population mean because. Per the Central Limit Theorem, the mean of the sample should approach the mean of the population as the sample size increases.
1) given function:
7
---------------
x^2 - 2x - 24
2) Vertical asymptotes are at the values ox x for which the function is not defined. These are the roots of the denominator polynomial.
You can factor the denominator to find those roots:
x^2 - 2x - 24 = 0 = (x - 6)(x + 4) => x = 6 and x = - 4
Therefore, the two vertical asymptotes are x = 6 and x = - 4
3) The function also has one horizontal asymptote:
Lim f(x) when x → +/- ∞ is 0, so y = 0 is also an asymptote.
Answer:
b=-2
Step-by-step explanation:
-(-b+5)+5b=-19-b
b-5+5b=-19-b
b+b-5+5b=-19-b+b
2b-5+5+5b=-19+5
2b+5b=-14
7b=-14
7b/7=-14/7
b=-2
Answer:
the 3 one
Step-by-step explanation:
1. Let the three boxes be box 1, box 2, box 3
consider the 2 white balls, they can be placed in the 3 boxes as follows:
BOX1: BOX2: BOX3:
__2___ ___0__ __0___
__0___ ___2__ ___0__
__0___ ___0__ ___2__
___0__ ___1__ ___1__
__1___ ___0__ ___1__
__1___ ___1__ ___0__
so there are 6 possibilities to place the white balls. Similarly there are 6 ways to place the black balls. We can combine any position of the black balls with any position of the white balls, so there are in total 6*6=36 ways to place the balls.
Answer: 36
