Y=mx+b
10x-19y=-19
—19y=-19+10x
Answer is Y=10/19x+1
48-10=x x=38
38x2= 76
so basically his weight is 48, which is ten more than his fathers weight, so you subtract ten from 48, giving you 38. 38 is only half the father's weight, so you double it and get 76.
Answer:
E) The probability of a Type II error would increase and the power of the test would decrease.
Answer:
55 degrees
Step-by-step explanation:
A complementary angle equals 90 degrees so you know that the two angles together must equal that. The easiest way to set up these problems are to turn it into an algebraic equation. You know that angle a is 20 more than angle b, or angle a is (x+20) and angle b is (x). Your equation would read: x+x+20=90. Simply solve this equation then plug in the answer to whichever angle you need. 2x+20=90, 2x=70, x=35. Angle A is 20 degrees longer making it equal 55.
