Answer:

$\mu_{x}=np$

$\sigma^2_{X}=np(1-p)$

Step-by-step explanation:

∵ When x is a random variable having distribution B(n, p), then for sufficiently large value of n, the following random variable has a standard normal distribution,

$\frac{x-\mu}{\sigma}\sim N(0,1)$

Where,

$\mu=np$

$\sigma^2=np(1-p)$

Here the variable X has a binomial distribution,

Such that, np (1 - p) ≥ 10 ⇒ n is sufficiently large.

Where, n is the total numbers of trials, p is success in each trials,

So, the mean of variable X is,

$\mu_{X} = np$

And, variance of variable X is,

$\sigma^2{X}=np(1-p)$

171 minutes
Explanation:
6 is the initial cost, .08 is the cost per minute and 19.68 is the total, set up an equation that looks like this: (x is the unknown variable)
6+.08x=19.68
19.68-6=13.68
.08x=13.68
.08x/.08=x
13.68/.08=171
x=171

PLS PLS PLS ANSWER 5 AND 6 AND TELL ME THE CORRECT ANSWER AND HOW TO GET THE CORRECT ANSWER THANK. WHOEVER ANSWER THIS CORRECTLY

yuradex [85]

The answer to 5 is A. And the answer to #6 is B. Here is why: So the cost for 6 pens is $2.34. So, you want to find the unit rate. The unit rate basically, in this case, would be how much on pen costs. So to find how much one pen costs you would divide 6 into $2.34. That would give you .39¢. Now to find out how much 20 pencils would cost you would multiply .39¢ by 20. This would give you $7.80. Do you see it now? I hope this could be helpful!
