Answer:
Point-Slope form:
standard form:
Step-by-step explanation:
The standard form is given by:
The point-slope form is given by:
- <em>Let's call
as point
, and</em>
<em>point as point
</em>
- <em>We also know that the slope
is given by
</em>
Let's find the slope:
1. So, point slope form can be written as:
2. Rearranging this equation and bringing all x's and y's to one side and the number to another side will give us the standard form. So:
<em>But A, B, and C (standard form) needs to be integers, so to get rid of the denominator , we multiply the whole equation by 15. So we have:</em>
<em>We can factor out a 3, so it becomes:</em>
So standard form is
Answer:
1. A: 0.25; B: 0.03; C: 1.41; D: -0.28
2. A: 0.39; B: 0.06; C: 40.30; D: 21.81
Step-by-step explanation:
For CDF lookups, we used the Excel NORMDIST(x, mean, stdev, TRUE) function. For inverse CDF lookups, we used the NORMINV(x, mean, stdev) function.
Each of these functions works with the area under the curve from -∞ to x, so for cases where we're interested in the upper tail, we subtract the probability from 1, or subtract the x value from twice the mean.
For question 1, we computed the Z values in each case. The NORMDIST function works directly with x, mean, and standard deviation, so does not need the z value.
Solve the system of linear equations below, using substitution method.
8x + 9y = 36
3x + 4y = 16
