Answer:
1.) a. i) f(4) = 2, ii.) f(-3)= -5 b.) x = -5, x = 2, c.) choice(2) -3 < x < 5
Step-by-step explanation:
Each problem
1.) a.) i.) we see f(4) = 2 on the graph the line goes through point (4, 2)
a.) ii.) f(-3) = -5
1.) b.) There are only 2 zeros for f(x) which intersect the x-axis in only 2 points.
x = -5 and x = 2 are the only 2 zeros.
1.) c.) only for -3 < x < 5 is the function f(x) increasing.
choice (2.)

Answer:
Step-by-step explanation:
Urn U1: 3 red and 2 yellow marbles, in total 5 marbles.
The probability to select red marble is 
Urn U2: 3 red and 7 yellow marbles, in total 10 marbles.
The probability to select red marble is 
Urn U1: 1 red and 4 yellow marbles, in total 5 marbles.
The probability to select red marble is 
The probability to choose each urn is the same and is equal to 
Thus, the probability that the marble is red is
Answer:
142
Step-by-step explanation:
<38 and <6 are vertical angles so they both measure 38
<6 and <5 are same side interior angles so they add up to 180
knowing this, you can simply subtract 38 from 180 to find <5
180 - 38 = 142
