The answer equals <span>2.394e+15</span>
Answer:
1 / 16
Step-by-step explanation:
Number of options = 4
Number of correct answers = 1
Number points gained for a correct answer = 1
Number of points lost for an incorrect answer = 1/4 = 0.25
Probability of choosing a correct option = 1/4
Probability of choosing an incorrect option = 3/4
x ____ 1 ______ - 1/4
P(x) __ 1/4 ______ 3/4
Expected gain or loss :
E(x) = Σx*p(x)
E(x) = (1 * 1/4) + (-1/4 * 3/4)
E(x) = 1/4 - 3/16
E(x) = (4 - 3) / 16
E(x) = 1 /16
A gain of 1/16

Answer:
<em>The time allotted is 46 minutes for an annual checkup and 29 minutes for a sick visit</em>
Step-by-step explanation:
<u>System of Equations</u>
It's required to write and solve a system of equations to model the situation of Dr. Jensen. Let's call the following variables:
x = time allotted for annual checkups
y = time allotted for sick visit
Dr. Jensen has 3 annual checkups and 1 sick visit for a total of 167 minutes on her schedule, thus:
3x + y = 167 [1]
It's also given she has 1 annual checkup and 1 sick visit on her schedule for a total of 75 minutes, thus:
x + y = 75 [2]
We'll solve the system formed by equations [1] and [2] using the elimination method.
Subtract [1] and [2]:
3x - x = 167 - 75
2x = 92
Divide by 2:
x = 46
Substitute in [2]:
46 + y = 75
Subtract 46:
y = 75 - 46 = 29
y = 29
The time allotted is 46 minutes for an annual checkup and 29 minutes for a sick visit
