Answer:
a) 1/2
b) 9/40
Step-by-step explanation:
Given
Total number of families living in Willbrook Farms Development = 20
Number of families preparing their own federal income taxes for last year = 10
Number of families for which taxes were prepared by a local professional = 7
Number of families for which taxes were prepared by H&R Block = 3
a) Probability of selecting a family that prepared their own taxes = 10/20 = 1/2
b) The probability of selecting two families, both of which prepared their own taxes
10/20 * 9/20 = 9/40

Answer:
Step-by-step explanation:
<u>The coordinates of E and F are:</u>
<u>Find the slope:</u>
- m = (- 4 - 4)/(2 - 4) = - 8 / - 2 = 4
<u>Use point-slope form and point E:</u>
<u>Convert into slope-intercept form:</u>
- y = 4x - 16 + 4
- y = 4x - 12
The matching choice is C
