You are to take a multiple-choice exam consisting of 100 questions with 2 possible responses to each question. Let x represent the number of correct responses on the test. A) What is your expected score on the exam?B) Compute the variance and standard deviation of x.
Answer:
50 ;
25 ;
5
Step-by-step explanation:
Given that:
Number of multiple choice questions = 100
Number of possible responses = 2
Hence, probability of success, p = 1/2 = 0.5
Using normal approximation :
The expected score = mean = n*p
Expected score (X) = 100 * 0.5 = 50
standard deviation = std(X) = √
Var(X) = n*p*q
q = 1 - p = 1 - 0.5 = 0.5
Variance = Var(X) = (100 * 0.5 * 0.5)
Var(X) = 25
Var(X) = 25
The Standard deviation (Std) = √Var(X)
Std(X) = √25
Std(X) = 5

A map has a scale of 2 inches = 50 miles. If the
distance between two cities on the map is 7 inches,
what is the actual distance between the cities?
Answer:
175 miles apart.
Step-by-step explanation:
This is because 2 goes into seven 3 times and half of 50 is 25 so for 1 inch it would be 25 miles. 50+50+50+25=175 miles.

You have discovered another alien. Find the correct rescue path before answering this question. Which statements are true about the equation of the line used to save this alien? The y-intercept is not visible on the graph. The slope does not exist for this line. The y-intercept is positive. The line crosses the x-axis at –3.
The correct answers are option A and option D.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction
From the given graph it is clear that the spaceship is located at (-4,3). The alien is at (-2, -3).
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
y - 3 = (-3 -3 ) / (-2 + 4) x (x + 4)
y - 3 = -3x -12
y = -3x -9
The equation of the line is;
y = -3x -9 {equation 1}
Slope intercept form of a line is
y = mx + b {equation 2} ,
where m is the slope and b is the y-intercept.
On comparing the equation (1) and (2) we get
It means,
Slope = -3
y-intercept = -9
Points from -6 to 6 are labeled on y-axis. The y-intercept is -9, so it is not visible on the graph.
Option A is correct.
Substitute y=0 in equation (1) to find the x-intercept.
Divide both sides by 3.
x-intercept is -3. It means the line crosses the x-axis at -3.
Option D is correct
Therefore, the correct options are A and D.
