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.

The table shows the lengths of four trails at a horseback riding camp. The estimated length of all four trails is 12 miles. Find a possible length for trail D. Show your work.
Answer:
Step-by-step explanation:
2.6 plus 1.8 plus 4.2 is 8.6. subtract this from 12 to get your answer of 3.4
If the estimated length of all four trails is 12 miles the possible length for trail D will be 3.4 miles.
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has basic four operators that are +, -, ×, and ÷.
Terms are similar, and we can perform arithmetic operations on them like addition and subtraction.
It is obtained from the table that the length of trails A, B, and C will be 2.6, 1.8, and 4.2 miles.
It is given that the estimated length of all four trails is 12 miles the length of Trail D is obtained by adding all the given lengths of the trails and subtracting it from the total length.
= 2.6 + 1.8, + 4.2 miles.
= 8.6 miles
The length of trail D is,
= 12 miles - 8.6 miles
= 3.4 miles.
Thus, if the estimated length of all four trails is 12 miles the possible length for trail D will be 3.4 miles.

A customer buys 5 books at a bookstore for a total cost of $65. If all the books cost the same amount, how much does 1 book cost?
Answer:
13
Step-by-step explanation:
Cost of 5 books = $65
So, cost of 1 book = $65 ÷ 5
= $13
The cost of one book is $13.
What is unit rate?A unit rate means a rate for one of something.
Given that, A customer buys 5 books at a bookshop for a total cost of $65.

that should be your answer.Suppose the radius of the cylinder is decreasing at a rate of 2 cm/sec, but the volume is constant. How fast is the height changing when the radius is 10 cm and the height is 35 cm? Include units with your answer. Hint: If the volume is constant, what do you know about the rate of change of the volume?
According to the question,
r = 10 cmh = 35 cm[tex]\frac{dr}{dt} = -2 \ cm/s[/tex]As we know the formula,
[tex]V = \pi r^2 h[/tex]then,
→ [tex]\frac{dv}{dt} = \pi [2r\frac{dr}{dt} h+ r^2 \frac{dh}{dt} ][/tex]
→ [tex]0 = \pi [2 \pi h\frac{dr}{dt} + r^2 \frac{dh}{dt} ][/tex]
By substituting the given values,
→ [tex]0 = 2\times 10\times 35\times (-2)+(10)^2\times \frac{dh}{dt}[/tex]
[tex]\frac{dh}{dt} = \frac{2\times 10\times 35\times 2}{10\times 10}[/tex]
[tex]\frac{dh}{dt} = \frac{140}{10}[/tex]
[tex]\frac{dh}{dt} = 4 \ cm/s[/tex]

Sophia is signing up for a gym membership with a one-time fee to join and then a monthly fee to remain a member. The one-time fee to join the gym is $100 and the total cost of membership, including the joining fee, would be $300 for 5 months. Write an equation for C,C, in terms of t,t, representing the total cost of the gym membership over tt months.
Answer:
40t+100
Step-by-step explanation:
The equation that represents the total cost of the gym membership over t months is C = 40t + 100.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

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.
