Answer:
Where's the model?
Hai there!
First, let's use the KCF technique (my old math teacher taught me this!)
Keep the first fraction the same, in this case, 1/2
Change the sign from division to multiplication
Flip the second fraction, or 3/8, to get it's reciprocal, or 8/3.
The new equation should look like this:
1/2 * 8/3
Now multiply straight across like you normally would, like so:
1 * 8 = 8
2 * 3 = 6

How would you graph Y = -2X? Explain from beginning to end.
Step-by-step explanation:
Since there is no y-intercept, you start at the origin (0, 0)
The slope tells us that for every two units it goes down, it also goes one unit to the right
We know this because slope is rise/run (in this case -2/1) and the slope is negative, meaning that it starts higher up at the left and goes down towards the right.
To graph, start at (0, 0) and go down 2 units to get (0, -2) and then to the right one unit to get (1, -2)
That is the first point
Continue doing this
(1, -2) -> down 2 and to the right 1 -> (2, -4)
Alternatively, plug in values for x
y = -2(1) -> y=-2
When x=1, y=-2
And keep repeating until you get a good idea of what the line looks like
find the discriminant for the following equation 3x^2+4x=2
Answer:
The discriminant is 40
Step-by-step explanation:
First, rewrite the equation as [tex]3x^2+4x-2=0[/tex] so that the equation is in the form of [tex]ax^2+bx+c=0[/tex]. Thus, the discriminant is [tex]b^2-4ac=(4)^2-4(3)(-2)=16+24=40[/tex]. This tells us that since the discriminant is greater than 0, then there are 2 real solutions.

Students in 10th and 11th grade were asked whether they have a job. The raw data was converted to relative frequencies and recorded in the table below. A 4-column table with 3 rows. The first column has no label with entries job, no job, total. The second column is labeled tenth grade with entries 0. 14, 0. 86, 1. The third column is labeled eleventh grade with entries 0. 25, 0. 75, 1. The fourth column is labeled total with entries 0. 20, 0. 80, 1. Given the conditional relative frequency table by column, what does the 0. 14 represent? Given that a student is a 10th grader, there is a 14% chance he or she has a job. Given that a student has a job, there is a 14% chance he or she is a 10th grader. 14% of the students surveyed are 10th graders who have a job. 14% of the students are 10th graders.
Option A is correct because 0.14 represents that if a student is a 10th grader, there is a 14% chance he or she has a job.
It is given that there is a table with 4 columns and 3 rows.
What is a conditional relative frequency table?It is a special type of frequency table that shows relationships between two categories.
From the attached table it is clear that 0.14 is the probability of getting a job if a student is a 10th grader,
Option B is incorrect, stating there is a 14% chance a student is a 10th grader if he/she has had a job because we do not know the number of students.
Option C is also incorrect stating that 14% of the students surveyed are 10th graders who have a job because we do not know the total number of students.
Option D is also incorrect because we do not know the number of students.
Therefore,Option A is correct because 0.14 represents that if a student is a 10th grader, there is a 14% chance he or she has a job.

Y -52 4 + 52 = 0 What is the solution to the system of equations?
Answer:
y = 156
Step-by-step explanation:
Solve for y:
y - 52 4 + 52 = 0
Multiply -52 and 4 together.
-52×4 = -208:
y + -208 + 52 = 0
Group like terms in y - 208 + 52.
Grouping like terms, y - 208 + 52 = y + (-208 + 52):
y + (-208 + 52) = 0
Evaluate 52 - 208.
52 - 208 = -156:
y + -156 = 0
Isolate terms with y to the left-hand side.
Add 156 to both sides:
y + (156 - 156) = 156
Hint: | Look for the difference of two identical terms.
156 - 156 = 0:
Answer: y = 156

Based on the information provided, it follows that there are 1,728 possible seating arrangements.
How can we find the number of possible arrangements?To find the number of arrangements in this problem situation we must take into account the following key factors:
Chris only has 1 possible seat.Jo has 2 possible seats.Dave, Alex, and Barb have 3 possible seats.Gareth, Fred, and Eddie have 3 possible seats.There are 4 other adults who do not have a preference in seats but have the possibility of using 4 seats.According to the above, we must use the factorization of these numbers to find out the number of possibilities we have to seat them.
What is factoring?A factorial function is a mathematical tool that is characterized by using the exclamation mark “!” behind a number. The factorial function is used to express that the number accompanied by the symbol must be multiplied by all positive integers between that number and 1.
In accordance with the above, in the problem situation that we must solve, we must use the factorial function with the possibilities of:
Dave, Alex and Barb: 3! = 3 × 2 × 1 = 6Gareth, Fred and Eddie: 3! = 3 × 2 × 1 = 6Other 4 adults: 4! = 4 × 3 × 2 × 1 = 24Subsequently, to calculate the number of total possibilities of the entire group we must multiply the possibilities of each group and individual as shown below:

A produce store sold 63 red apples. If the ratio of red apples to green apples sold was 7: 2, what is the combined amount of red and green apples sold?
Answer:
81 apples
Step-by-step explanation:
7 divided by 2 = 3.5
63 divided by 3.5 = 18
63 red + 18 green = 81 total apples
Answer:
81
Step-by-step explanation:
If we just divide 63 by 7 we can understand the value of the units used in the ratio
63/7 = 9
So that means the value of one unit on the ratio is 9
2*9 = 18 = amount of red apples
63 + 18 = 81

Phone calls arrive at the rate of 48 per hour at the reservation desk for regional airways.
A) Compute the probability of receiving three calls in a 10-minute interval of time?(to 4 decimals)
B) Compute the probability of receiving exactly 13 calls in 15 minutes. (To 4 decimals)
C) Suppose no calls are currently on hold. If an agent takes 10 minutes to complete the current call, how many callers do you expect to be waiting by that time?
D) What is the probability that none will be waiting?
E) If no calls are being processed, what is the probability that the agent can take 5 minutes for a personal time without being interrupted by a call?
The different probabilities and number of callers expected to be waiting are;
A) P(x = 3) = 0.0286
B) P(x = 13) = 0.1056
C) 8 will be waiting
D) P(x = 0) = 0.0003
E) P(x = 0) = 0.0067
How to find probability using Poisson distribution?
We are given the rate of 48 phone calls per hour.
Thus, we will use poisson's distribution formula;
P(x) = (λˣ × e^(-λ))/x!
A) Probability of receiving three calls in a 10-minute interval of time which is P(x = 3). Thus;
λ = 48 * (10/60)
λ = 8
P(x = 3) = (8³ × e⁻⁸)/3!
P(x = 3) = 0.0286
B) Probability of receiving exactly 13 calls in 15 minutes is P(x = 13). Thus;
λ = 48 * (15/60)
λ = 12
P(x = 13) = (12¹³ × e⁻¹²)/13!
P(x = 13) = 0.1056
C) No calls are currently on hold and it takes 10 minutes to complete one call. Thus;
λ = 48 * (10/60)
λ = 8
Thus, 8 will be waiting after 10 minutes.
D) Probability that no one will be waiting is;
P(x = 0) = (8⁰ × e⁻⁸)/0!
P(x = 0) = 0.0003
E) No calls being processed and it takes 5 minutes for a personal time without being interrupted by a call. Thus;
λ = 48 * (5/60)
λ = 4
P(x = 0) = (4⁰ × e⁻⁵)/0!
P(x = 0) = 0.0067

Find scale factor
QR=9unitsQ'R'=3unitsScale factor:-
k=3/9k=1/3Yes Option A is correct
Answer:
A. The edge lengths of the smaller figure are less than half those of the large figure.
[tex]\sf Scale\:factor=\dfrac13[/tex]
Step-by-step explanation:
From inspection of the graph, the pre-image is QRST and the dilated image is Q'R'S'T'.
We can see that Q'R'S'T' is a reduction of QRST since it is smaller.
Inspect the length of the corresponding line segments of both images and compare.
T'S' = 3 units
TS = 9 units
[tex]\sf \dfrac{T'S'}{TS}=\dfrac{3}{9}=\dfrac13[/tex]
Therefore, T'S' is [tex]\sf \frac13[/tex] the length of TS.
As [tex]\sf \frac13 < \frac12[/tex], the edge lengths of the smaller figure are less than half those of the large figure (answer option A)
The scale factor is the amount we have to multiply the sides of QRST by to get Q'R'S'T'. Therefore, the scale factor for the side lengths in this dilation is [tex]\sf \frac13[/tex]
How many students can a van and a bus carry?
Answer: A van can carry up to 7-14 people a hooded school bus can carry up to 60 people the flat buses can carry up to 90 people.
Step-by-step explanation:
Train A stops every 35 minutes and Train B stops
every 15 minutes. If both trains stop at 7:30
a.m., what is the next time they will both stop at
the same time?
You're looking for the smallest number that's a multiple of both 30 and 40.
If you've learned about "Least Common Multiple" by now, you'll be happy
to know that that's exactly what this is, (because when you were learning it,
you wondered what in the world you could ever use it for). Well here you are.
The least common multiple of 30 and 40 is 120.
That's the 4th multiple of 30 and the 3rd multiple of 40.
If the trains are both in the station right now, then the next time they'll
both be here together will be 2 hours (120 minutes) from now.
And let me say in conclusion that when you ask for help with
a multiple-choice question, you must also post the choices that
you have. It's not fair to the helper if he doesn't know the choices
