Which of the following would not be an example of a compound event?
(1) having a coin land on heads three consecutive times
(2) pulling a king out of a deck of cards
(3) missing two free throws in a row
(4) answering four true/false questions correctly by guessing
The only option that is not a compound event is; (2) pulling a king out of a deck of cards
How to identify a compound event?Compound probability is defined as a mathematical term that relates to the likeliness of two independent events occurring.
Thus, a simple event has only one outcome while a compound event involves the probability of more than one outcome
1) For a coin to land on heads three consecutive times means that there can only be three possible independent outcome and so this is a compound event.
2) Pulling a king out of a deck of cards is a simple event and not compound because it has only one outcome.
3) This is a compound event because we are dealing with two independent probabilities.
4) This is a compound event because we are dealing with two independent events which are true or false answers.

During the last class period of the semester, each student in a graduate computer science class with 10 students is required to give a brief report on his or her class project. The professor randomly selects the order in which the reports are to be given. Two students have been working on similar projects and would like to give their reports consecutively. What is the probability that this will happen
Answer:
Probability = 1/5
Step-by-step explanation:
Total ways of arrangement for 10 students = 10 !
Ways to arrange 2 students consecutively & other 8 students = 9 ! x 2
( As 9! to arrange 9 units, as 2 considered together ; & 2 for arranging 2 consecutive students - respectively )
So, Probability = Favourable outcomes / Total outcomes
= ( 2 x 9! ) / 10! = ( 2 x 9 x 8 x ..... 2 x 1 ) / 10 x 9 x ....... 2 x 1)
= 2 / 10 = 1/5

Answer:
5.5; 11.00; 16.50
[tex]E = 5.5h[/tex]
Step-by-step explanation:
Given
The attached table
Solving (a): Complete the table
First, calculate the slope (m)
[tex]m = \frac{E_2 - E_1}{h_2 - h_1}[/tex]
So:
[tex]m = \frac{27.5- 22.00}{5-4}[/tex]
[tex]m = \frac{5.50}{1}[/tex]
[tex]m = 5.50[/tex]
So, the equation of the table is:
[tex]E = m(h - h_1) + E_1[/tex]
[tex]E = 5.5(h - 4) + 22[/tex]
[tex]E = 5.5h - 22 + 22[/tex]
[tex]E = 5.5h[/tex]
When h =1,2,3
[tex]E = 5.5 * 1 = 5.5[/tex]
[tex]E = 5.5 * 2 = 11.00[/tex]
[tex]E = 5.5 * 3 = 16,50[/tex]

Why is the discriminant a useful tool to use when solving quadratic equations?
Nevaeh has $0.80 worth of nickels and dimes. She has a total of 11 nickels and dimes altogether. Graphically solve a system of equations in order to determine the number of nickels, x,x, and the number of dimes, y,y, that Nevaeh has.
Answer: We can set up a system of equations to represent this problem. The first equation represents the total value of the nickels and dimes in terms of the number of nickels and dimes that Nevaeh has:
0.05x + 0.1y = 0.80
The second equation represents the total number of nickels and dimes that Nevaeh has in terms of the number of nickels and dimes that she has:
x + y = 11
To graphically solve this system of equations, we can use the slope-intercept form of the linear equations.
y = -2x + 22
y = -1/2 x + 8
The solution would be the point where the lines intersect , which x = 4, and y = 7 .
So she has 4 nickels, and 7 dimes.

A company that makes fasteners has government specifications for a self-locking nut. The locking torque has both a maximum and minimum specified. The offsetting machine used to make these nuts has been producing nuts with an average locking torque of 8.62 in-lb and variance of 4.49 squared in-lb. Torque is normally distributed. If the upper specification is 13.0 in-lb and the lower specification is 2.25 in-lb, what percent of these nuts will meet the specification limits
Answer:
97.95% of these nuts will meet the specification limits.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The offsetting machine used to make these nuts has been producing nuts with an average locking torque of 8.62 in-lb and variance of 4.49 squared in-lb.
This means that [tex]\mu = 8.62, \sigma = \sqrt{4.49}[/tex]
Torque is normally distributed. If the upper specification is 13.0 in-lb and the lower specification is 2.25 in-lb, what percent of these nuts will meet the specification limits?
The proportion is the p-value of Z when X = 13 subtracted by the p-value of Z when X = 2.25. So
X = 13
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{13 - 8.62}{\sqrt{4.49}}[/tex]
[tex]Z = 2.07[/tex]
[tex]Z = 2.07[/tex] has a p-value of 0.9808.
X = 2.25
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{2.25 - 8.62}{\sqrt{4.49}}[/tex]
[tex]Z = -3.01[/tex]
[tex]Z = -3.01[/tex] has a p-value of 0.0013.
0.9808 - 0.0013 = 0.9795
0.9795*100% = 97.95%
97.95% of these nuts will meet the specification limits.

A light bulb consumes 5400 watt-hours in 3 days and 18 hours. How many watt-hours does it consume per day?
We are given:
Time period: 3 days and 18 hours
Energy consumed in given time period: 5400 watt-hours
Converting time to hours:
We know that one day is 24 hours
So, 3 days = 72 hours
Time period = 3 days + 18 hours
Time period = 72 hours + 18 hours
Time period = 90 hours
Converting to days
Time period = 3.75 days
Watt-hour consumption in a day:
Consumption = 5400 watt-hours / 3.75 days
Consumption = 1440 watt-hours/day

x<3 is the solution of the equation 3 + (x-2) / (x-3) ≤ 4.
What is Inequality?A relationship between two expressions or values that are not equal to each other is called 'inequality.
The given equation can be rewritten as 3 + (x-2) / (x-3) ≤ 4.
To solve for x, we need to multiply both sides by (x-3)
3(x-3) + (x-2) ≤ 4(x-3).
3 + x-2/x-3 -4 ≤ 0
Solve the above equation.
-1 + x-2/x-3 ≤ 0
-(x-3) + x-2/x-3 ≤ 0
1/x-3 ≤ 0
x-3 < 0
x < 3

the number of degrees the temperature drops
the rate at which the temperature drops
the day of the week
Help me plz I’ll give Brainlyest
Answer:
the rate at which the temperature drops
the day of the week
Step-by-step explanation:
Since we can choose the number of hour, it is dependent on us.
If we set time = 2, then it would 5 x 2 = 10 degree
Similarly, if we change time, the temperature changes. Thus, it is dependent.
Temperature is dropping at a rate of five degrees per hour.
If t = 1, T = 5*1 = 5°, rate = 5
if t = 2, T = 5*2 = 10°, rate = 5
if t = 3, T = 5*3 = 15°, rate = 5
Notice that rate doesnt change, even the temperature and time changes.
Thus, rate is independent.
