Answer:
The line equation in slope-intercept form is:
Hence, option D is true.
Step-by-step explanation:
Given the points
Finding the slope between the points
As the y-intercept is obtained by setting the value x = 0.
As we know that when x = 0, the vale of y-intercept y = 4
so the y-intercept is b = 4.
As the slope-intercept form is
substituting the slope m = -2/5 and the y-intercept b=4
Therefore, the line equation in slope-intercept form is:
Hence, option D is true.

Answer:
4
Step-by-step explanation:
25,437 --> twenty-five thousand, four hundred and thirty seven
A. np is the mean=8×0.20=1.60; variance=np(1-p)=1.60×0.80=1.28. Standard deviation=√variance=1.13 approx.
b. The coefficients for n=8 are: 1, 8, 28, 56, 70, 56, 28, 8, 1.
The first 4 of these are involved in getting 5 or more successes. Let q=1-p. p=0.20 and q=0.80.
So we have p⁸+8p⁷q+28p⁶q²+56p⁵q³=0.0104... This is a very low probability, so it would be unusual to obtain 5 or more successes.
