Step-by-step explanation:
8!/(2!x2!x2!)
8 letters in the word / 2r's 2e's 2t's
The number of ways in which the letters can be arrange is 5,040 ways.
The given letters include;
BARRETTE
The numbers of the individual letters repeated include;
letter R = 2letter E = 2letter T = 2Total number of all the letters = 8
The number of ways in which the letters can be arrange will be determined using factorial method as shown below;
[tex]number \ of \ ways = \frac{8!}{2! \times 2! \times 2!} = \frac{40320}{8} = 5,040 \ ways[/tex]
Thus, the number of ways in which the letters can be arrange is 5,040 ways.

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
Given is Susan who has to complete 30 hours of community service.
The equation representing the hours of service, Susan has left after [x] days is -
y = 30 - 2x
OR
y = - 2x + 30
Refer to the graph attached.
For the graph of the equation, the y-intercept refers to the total hours of service
Therefore, the y-intercept refers to the total hours of service.

Answer:
the correct answer is marked (1/2)
Step-by-step explanation:
The average rate of change is the slope of the line between the two points at the ends of the interval.
m = (g(3) -g(-4))/(3 -(-4))
The values of the function we need are ...
g(3) = 5/(3-1) +2 = 2.5 +2 = 4.5
g(-4) = 5/(-4-1) +2 = -1 +2 = 1
So, the slope is ...
m = (4.5 -1)/7 = 3.5/7 = 1/2
The average rate of change is 1/2.
_____
On the attached graph, that value shows up as the coefficient of x in the equation of the line through the two points.

Answer:
5 gallons of the 10% fructose solution.
15 gallons of 20% fructose solution
Step-by-step explanation:
You basically have an equation
Some amount of 10% solutions and some amount of 20% are to be combined to get to 17.5
So we can label those two amounts x and y, x being 10% and y being 20%.
We know that x + y (in gallons) must be equal to 20 gallons, so we can do this
x+y = 20
y = 20-x.
Then we can multiply x by 10% = 0.1x, 20-x by 20% which makes 4-0.2x
Then we know that the end result must be 20 gallons of 17.5% so we can multiply those two to get 3.5
Then we can add all of our results.
0.1x + 4 - 0.2x = 3.5
Solve for x
-0.1x = -0.5
x = 5
Now we have what x is, so we now know that there was 5 gallons of the 10% fructose solution.
Then we know that y = 20 - x so y is equal to 20 - 5 which is 15.
So that means that 15 gallons of 20% fructose solution was used.
So the answer is
5 gallons of the 10% fructose solution.
15 gallons of 20% fructose solution.

(7 3 points) Consider a packet stream whereby packets arrive according to a Poisson process with rate 10 packets/s. If the interarrival time between any two successive packets is less than the transmission time of the first, the two packets are said to collide. Find the probability that a packet collides with either its predecessor or its successor assuming that all packets have a transmission time of 20 ms. How will your answer change if the packets have independent, exponentially distributed transmission times
Answer:
The answer is below
Step-by-step explanation:
Let t1 be the arrival times between a packet and its immediate predecessor and t2 be the arrival times between a packet and successor. Let L1 be the lengths of the predecessor packet and L2 the length of the packet itself. Therefore:
P(no collision between packet and predecessor or successor) = [tex]P(t_1>L_1)P(t_2>L_2)[/tex]
If P1 is the probability that there is no collision with preceding packets, hence:
P(no collision with other packets) = [tex]P_1*P(t_2>L_2)[/tex]
λ = 10 packets/s, fixed packet length = 20 ms = 0.02 s. Hence:
[tex]P(t_1>L_1)=P(t_2>L_2)=e^{-\lambda *0.02}=e^{-10*0.02}=e^{-0.2}[/tex]
P(no collision between packet and predecessor or successor) = [tex]P(t_1>L_1)P(t_2>L_2)[/tex] = [tex]e^{-0.2}*e^{-0.2}=e^{-0.4}[/tex]
P(packet collides with either its predecessor or its successor) = 1 - P(no collision between packet and predecessor or successor) = [tex]1-e^{-0.4}=0.33[/tex]
If the transmission times change, the answer would also change.
Jen was making cake pops for the bake sale. After 3 hours, she had completed half of the work. She called Maryna for help and together they finished everything in half an hour. How long would it take Maryna to finish the job alone if she replaced Jen after Jen baked for 3 hours? PLS HELP!!!!!!!!
Answer:
0.6 hours
Step-by-step explanation:
Let's say J is Jen's speed (cake pops per hour), and let's say M is Maryna's speed (cake pops per hour).
Let's say there are 12 cake pops total that need to be made. Jen made half of the cake pops in 3 hours, so she made 6 cake pops in 3 hours. So her speed is 2 cake pops per hour.
Then, Jen and Maryna made the other half of the cake pops in 1/2 hour. Therefore, their combined speed is:
J + M = 6 cake pops / (1/2 hr)
J + M = 12
2 + M = 12
M = 10
So Maryna can make 10 cake pops per hour.
If Maryna was working alone, the amount of time it would take her to make 6 cake pops is:
6 cake pops / (10 cake pops per hour) = 0.6 hours
It would take 0.6 hours, or 36 minutes.
When attempting to study for her next Science exam, Alma cannot arrange her notes into the correct order. What has Alma forgotten to do? a. Include the name of the guest speakers on each page of notes c. Include the date on each page of notes b. Include the class title on each page of notes d. All of these
Answer:
c. Include the date on each page of notes
Step-by-step explanation:
The main reason for her not being able to do this is because she did not include the date on each page of notes. Failing to do so means that she does not know which notes she took first and which ones she took later, therefore preventing her from correctly organizing the notes based on when they were taken (in the correct order). Neither the class title or the names of the guest speaker prevent her from organizing her notes in order, thus making the answer c.
Answer: It is c
Step-by-step explanation: when arranging notes it is very important to remember what you are doing and how you are doing it.

A lock has a code of 3 numbers between 1 and 25. If no numbers in the code are allowed to repeat, how many different codes could be made?
The number of different codes is 192.
What is a combination?It is an arrangement of a set of numbers from a total set where the order of the set is not relevant.
We have,
The formula for combination is [tex]^nC_r[/tex] = n! / r! (n -r)!
Now,
Total numbers = 25
n = 25
Required numbers of code = 3
Now,
The number of different codes.
= [tex]^{25}C_3[/tex]
= 25! / 3! (25 - 3)!
= 25 x 24 x 23! / 3 x 2 x 23!
= 25 x 24 / 3 x 2
= 24 x 8
= 192
Thus,
The number of different codes is 192.

Data was collected for 40 randomly selected trees growing in the median strip of a busy freeway. The height of each tree (in inches) was recorded. Data was recorded to the nearest whole inch. The data is summarized in the histogram below.
2 4 6 8 10 height (in) 10 15 20 25 30 35 40 45 50 Frequency
What is the maximum possible tree height for the data recorded for this histogram? Note: Each class contains its lower class boundary, but not its upper class boundary.
Minimum tree height = inches Maximum tree height = inches
answer:
minimum = 20 inches
maximum = 49 inches
Step-by-step explanation:
The height data in the question is
10 15 20 25 30 35 40 45 50.
From above we have the classes as:
10-14, 15-19, 20-24, 25-29, 30-34, 35-39, 40-44, 45-49,
The minimum tree height bus from the first class. While the maximum tree height is from the last class.
The first class is 10-14, so the minimum height = 10 inches
The last class is 45-49 so the maximum height inches = 49 inches.
The maximum tree height from the classes I have grouped is 49 inches since 49 is the upper limit from the last class.
The minimum tree height is 10 inches
find the value of the variable and the measure of each labeled angle.
Answer:
x = 25
Measure of each angle label is 42°
Step-by-step explanation:
(x + 17)° and (3x - 33)° are the expressions of the two vertical angles formed by the intersection of two straight lines. Vertical opposite angles are congruent. Therefore:
x + 17 = 3x - 33
Solve for x. Collect like terms
17 + 33 = 3x - x
50 = 2x
Divide both sides by 2
50/2 = 2x/2
25 = x
Measure of the two angles are:
x + 17 = 25 + 17 = 42° (substitution)
3x - 33 = 3(25) - 33 = 75 - 33 = 42°
