See attachment for complete question.
From the attachment, we have that:



First, we calculate the total



Solving (a): Probability of A
This is calculated using:



Solving (b): Probability of C
This is calculated using:



Solving (b): Probability of T
This is calculated using:



Answer:
If you choose any value for k other than 6, that will be give you the one solution.
If k=6, you have no solutions because the lines will be parallel.
Step-by-step explanation:
We are going to put each of this in y=mx+b where m is the slope and b is the y-intercept.
kx+2y=5
Subtract kx on both sides:
2y=-kx+5
Divide both sides by 2:
y=(-k/2)x+(5/2)
The slope is -k/2 and the y-intercept is 5/2
3x+y=1
Subtract 3x on both sides:
y=-3x+1
The slope is -3 and the y-intercept is 1.
We want the system to have one solution so we want the slopes to be difference.
So we don't want (-k/2)=(-3).
Multiply both sides by -2: k=6.
We won't want k to be 6.

Step-by-step explanations:
(A) This equation evaluates the cost to ship 100 lbs of wheat, which equals $130:
C(100) = 1.28(100) + 2
C(100) = 128 + 2
C(100) = 130
(B) The cost to ship 250 lbs of wheat would be $322:
C(250) = 1.28(250) + 2
C(250) = 320 + 2
C(250) = 322
(C) If you had $50, you could ship 37.5 lb of wheat:
C(x) = 50
C(x) = 48 + 2
C(x) = 1.28(37.5) + 2
Answer:
Sarah = 78
Lee = 79
Step-by-step explanation:
98 + 100 + 65 + 78 + 98 + 46 + 100 + 100 + 45 + 50 = 780
780÷10= 78
97 + 67 + 89 + 99 + 100 + 45 + 79 + 89 + 58 + 67 =
790
790÷10=79
