assume that the class has 80 students and that the examination period is 95 minutes in length. How many students do you expect will be unable to complete the exam in the allotted time
Answers
Answer:
Number of students successful= 75
Number of students not able to complete the exam in the allotted time= 5
Step-by-step explanation:
In this question the main part is missing .The given statement is the sub part of the problem .
Suppose the main part is
The time needed to complete a final examination in a particular college course is normally distributed with a mean of 80 minutes and a standard deviation of 10 minutes.
If the main part was given like this only then we could do the following calculations.
So from above the
Population mean = μ= 80
Population Standard deviation =σ= 10 mins
Sample mean = x`= 95
Sample size= n= 80
Now first we calculate the z= score
z= x`-μ/σ
z= 95-80/10= 1.5
From the z- table we find the P (z< 1.5)= 0.9332
Now we have to find the number of students who need to complete the exam in the allotted time
Number of students successful= np= 80 * 0.9332= 74.656= 75
Number of students not able to complete the exam in the allotted time= 80-75= 5
These answers are based on the main part supposed to be as added just to explain how it will be calculated.

Answers
Answer:
a. False
b. True
c. True
d. True
e. False
Step-by-step explanation:
You want to know the truth value of various logical expressions when b = False, and x = 0.
And, OrAn And (&&) expression is true if and only if all parts are true. An OR (||) expression is true if any part is true.
When 'b' is false, b&&__ will be false, and !b||__ will be true. This makes (a) and (e) false, and (d) true.
When x = 0, __||x==0 will be true, so (b) is true.
The And (&&) of expression (c) will only be true when both parts are true. For b = False and x = 0, both parts are true, so (c) is true.
{a, b, c, d, e} = {False, True, True, True, False}

A six-sided die is tossed and a coin is flipped. What is the fractional probability that the die lands on 4, 5 or 6 and the coin is tails?
Answers
Answer:
1/8
Step-by-step explanation:
The fractional probability that the die lands on 4, 5 or 6 and the coin is tails is 1 / 4.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of samples
Given that a six-sided die is tossed and a coin is flipped. The die lands on 4, 5 or 6 and the coin are tails.
The probability of getting 4, 5, and 6 is,
P = 3 / 6
P = 1 / 2
The probability of getting tail,
P = 1 / 2
The probability that the die lands on 4, 5 or 6 and the coin is tails is,
Probability = ( 1 / 2 ) x 9 1 / 2 )
Probability = 1 / 4

1. An acrobat is on a platform that is 25 feet in the air. She jumps down
at an initial vertical velocity of 4 ft/s. Write a quadratic function to
represent the height h of the acrobat t seconds after the jump.
If a safety net is placed 5 feet above the ground, how long will it take
for her to land safely on the net?
Answers
It will take the acrobat 1/4 of a second to land safely on the net.
What is velocity?Velocity is a physical quantity that measures the rate at which an object moves in a particular direction. It is measured in terms of distance traveled per unit of time, usually expressed in terms of meters per second (m/s). Velocity is a vector quantity, meaning it has both a magnitude and a direction. It is an important concept in physics and is used to understand the motion of objects and forces.
The quadratic equation representing the height h of the acrobat t seconds after the jump can be written as follows: \(h=-16t^2+4t+25\).
To find the time it takes for the acrobat to land safely on the net, we need to solve for t when h=5. We can do this by substituting 5 for h into the equation and solving for t:
\(h=-16t^2+4t+25\\\\5=-16t^2+4t+25\\\\=-16t^2+4t-20=0\\\\(4+\sqrt{64})/(-32)=t\\ \\t=(4+8)/(-32)\\\\t=1/4\)
Therefore, it will take the acrobat 1/4 of a second to land safely on the net.

A fraternity charge $2.00 admission for dudes and $1.00 admission for ladies. They made $45 and sold 35 tickets how many ladies attended the party
Answers
After solving the equations, we know that a total of 25 ladies attended the party.
What are equations?A mathematical statement that has an "equal to" symbol between two expressions with equal values is called an equation.
As in 3x + 5 Equals 15, for instance.
Equations come in a variety of forms, including linear, quadratic, cubic, and others.
So, take dudes as x and ladies as y.
Now, form the required 2 equations as follows:
2x + y = 45 ...(1)
x + y = 35 ...(2)
Work on equation (2):
x + y = 35
x = 35 - y
Now, substitute x = 35 - y in equation (1):
2x + y = 45
2(35-y) + y = 45
70 - 2y + y = 45
-y = -25
y = 25
Since ladies were charged $1 for each ticket, then 25 ladies attended the party.
Therefore, after solving the equations, we know that a total of 25 ladies attended the party.

Find the following trigonometric values.
Express your answers exactly.
cos(330)
sin(330)
Answers
The exact values of the given trigonometric functions are:
cos(330) = \(\sqrt{3}/2\) or 0.866
sin(330) = 1/2 or 0.5
To find the trigonometric values of cos(330) and sin(330) exactly, we can use the unit circle and the properties of the trigonometric functions.
In the unit circle, the angle of 330 degrees is equivalent to -30 degrees or \(-\pi/6\) radians. Since cosine is an even function, we know that \(cos(-\theta) = cos(\theta)\), so we can find cos(-30).
Using the special triangles and the reference angle of 30 degrees, we can determine the exact values:
cos(-30) = cos(30) = \(\sqrt{3}/2\)
Similarly, the sine of -30 degrees is the same as the sine of 30 degrees:
sin(-30) = sin(30) = 1/2
Therefore, the exact values are:
cos(330) = cos(-30)= cos(30) = \(\sqrt{3}/2\) or 0.866
sin(330) = sin(-30)= sin(30)= 1/2 or 0.5

I need help graphing systems of inequalities and showing all the possible solutions
Answers
Given the system of inequalities
\(y>-2x+5\)\(y\leq x-3\)To graph an inequality you have to apply a method similar to the one you apply when graphing linear equations.
For each inequality, you have to find at least two points of the line and draw it, then shadow the area corresponding to the inequality.
For the first expression
\(y>-2x+5\)First, determine two points to draw the line that determines the minimum value of the inequation.
For x=0
\(\begin{gathered} y>-2\cdot0+5 \\ y>5 \end{gathered}\)For x=2
\(\begin{gathered} y>-2\cdot2+5 \\ y>1 \end{gathered}\)Once you plotted the line, since the inequality is determined to the values greater than it, you have to shade the area above it.
For the second expression
\(y\leq x-3\)For x=0
\(\begin{gathered} y\leq0-3 \\ y\leq-3 \end{gathered}\)For x=3
\(\begin{gathered} y\leq3-3 \\ y\leq0 \end{gathered}\)With the two points, you can plot the line. Note that the inequality indicates its range is all values equal or less than the line, so you have to shade the area below the line.

Given the graph below, find GH.

Answer:
The answer is below
Step-by-step explanation:
Let us assume that each box represent 1 unit. Therefore we can get the coordinate of G and H. From the graph, the coordinate of G is (-2, -3) while the coordinate of H is at (0, 3).
The distance between two points A(\(x_1,y_1\)) and B(\(x_2,y_2\)) on the coordinate plane is:
\(|AB|=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\)
The distance between G(-2, -3) and H(0, 3) is:
\(|GH|=\sqrt{(0-(-2))^2+(3-(-3))^2}=\sqrt{4+36}=\sqrt{40}\\ \\|GH|=6.325\ units\)
Using the distance formula, GH = 6.3 units.
What is the Distance Formula?Given the coordinates of two points on a coordinate plane, the formula for finding the distance between them is: \(d = \sqrt{(y_2 - y_1)^2 + (x_2 - x_1)^2}\)
Given:
H(0, 3)G(-2, -3)Plug in the values into the distance formula:
