Answer: The equation for a line is y = mx + b. B is the y-intercept (where x=0). If your B value is 6, then your y-intercept is (0,6). This is the same with negatives, if you have a negative B value, then the y-intercept is below the x-axis. For example, a B value of -6 would mean that the line crosses the y-axis at (0,-6).

M is your slope. Your slope can be determined by rise/run (how far your line goes up between each point/how far horizontally your line travels between each point). A slope of 2 would mean that the y-values on my line are double the x-values on my line. If a point on the line was (1,2), we could find the slope value by taking 2 and dividing it by 1.

If I had y = 6x+2, my slope would be 6, and my y-intercept would be 2.

Feel free to ask anything is still a little confusing :D

Suppose a random sample of n measurements is selected from a binomial population with probability of success p = .39. Given n =
Oksi-84 [34.3K]

Answer:

The answer is below

Step-by-step explanation:

a) Given that the number of sample (n) = 300, therefore since n > 30, the distribution of the sample means is going to be normally distributed.

b) The mean of the distribution of sample means (also known as the Expected value of M) is equal to the population mean μ.

\mu_x=\mu=np=300*0.39=117

c) The standard deviation of the distribution of sample means is called the Standard Error of M, it is given by:

\sigma_x=\sqrt{np(1-p)} =\sqrt{300*0.39(1-0.39)} =8.44

Midpoint of the x intercepts of f(x)=(x-4)(x+4)
lorasvet [3.4K]
The x-intercept is defined to be the value of x when y is zero. Based on the graph of the function: f(x) = (x-4)(x+4), the x-intercepts are located at (-4, 0) and (4,0). At these points the graph intersects the x-axis. The midpoint of the x-intercepts is located at the middle of the two points. In this case, the graph shows that it is at the origin or at (0,0).

we have that

Applying proportion

x/9=5.5/3

solve for x

x=9*(5.5/3)

x=16.5 ft

therefore
