Find the distance between -452 and 12.
Answer: 440
Step-by-step explanation: You add 12 to -452

let x1, x2 ..., x100 all be independent bernoulli variables, which take a value of 1 with probability 0.5
Using the normal approximation to the binomial, there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.
What is the missing information?This problem is incomplete, but researching it on a search engine, it asks the probability that the sum of these Bernoulli variables is of less than 60.
Normal Probability DistributionThe z-score of a measure X of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex] is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The z-score measures how many standard deviations the measure is above or below the mean. Looking at the z-score table, the p-value associated with this z-score is found, which is the percentile of X.The binomial distribution is the probability of x successes on n trials, with p probability of a success on each trial. It can be approximated to the normal distribution with [tex]\mu = np, \sigma = \sqrt{np(1-p)}[/tex].The binomial distribution is a series of n Bernoulli trials with p probability of a success on each trial, hence the parameters for the binomial distribution are given as follows:
n = 100, p = 0.5.
The mean and the standard deviation are given by:
[tex]\mu = np = 100(0.5) = 50[/tex].[tex]\sigma = \sqrt{np(1-p)} = \sqrt{100(0.5)(0.5)} = 5[/tex]Using continuity correction, the probability that the sum is less than 60 is P(X < 59.5), which is the p-value of Z when X = 59.5, hence:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
Z = (59.5 - 50)/5
Z = 1.9
Z = 1.9 has a p-value of 0.9713.
Hence there is a 0.9713 = 97.13% probability that the sum of these variables is less than 60.

Find an equation for the line below.
To find the equation of a line, you need to use the formula [tex]m=\frac{y-y_0}{x-x_0}=\frac{rise}{run}[/tex] to find the slope first.
To find the respective points that we need to plug into this formula, we need to use the axes and their values.
We can see that the first point (point on the left) has a position of (-1, -1). For the second point, we see that it has a position of (5, 1).
** remember, whenever you find the position of a point, it's always (x, y). Now that we have our values, we can plug and chug!
[tex]m=\frac{y-y_0}{x-x_0}\\m= \frac{1-(-1)}{5-(-1)} \\m=\frac{1+1}{5+1} \\m=\frac{2}{6} \\m=\frac{1}{3}[/tex]
So your answer should be 1/3 for your slope.
Now you need to find your y intercept, or what y will equal if x = 0. We can find this by using the information we now have. Remember, the equation for a linear line is [tex]y=mx+b[/tex]. So now, we plug in any of the two points (it doesn't matter which pair!) and solve for b!
[tex]y=mx+b\\-1=\frac{1}{3}(-1)+b\\ -1=-\frac{1}{3}+b\\-1+\frac{1}{3}=b\\b=-\frac{2}{3}[/tex]
Now we have b!
So now, we can fully finish the equation of this line. Your final answer should be: y = (1/3)x - 2/3 or [tex]y=\frac{1}{3}x-\frac{2}{3}[/tex].
