a/4 - 5/6 = 1/2
a/4 - 5/6 = 1/2 help
Answer:
a = 16/3 or 5 1/3 or 5.33...
Step-by-step explanation:
to find a you must first make all of the denominators the same
you must find 4 6 and 2s CGF
and that is 12
so multiply a/4 by 3/3 and get 3a/12
then multiply 5/6 by 2/2 and get 10/12
and lastly multiply 1/2 by 6/6 and get 6/12
at this point you can set the equation up like this
3a/12 - 10/12 = 6/12
but then you can multiply everything by 12
3a - 10 = 6
and then solve
add 10 to both sides
3a = 16
then divide 3 on each side
a = 16/3 or 5 1/3 or 5.33...

4. If the radius of a circle is 24 feet, what is the diameter?
Answer: 12
Step-by-step explanation:
on the last night of scout camp Chris his wife Joe and the 11 other adults sit down for supper along one side of a long rectangular table Chris takes the central seat six adults on each side of him Joe must sit next to Chris Alex Bob and David system being next to one another in any order on the side to Chris's left teddy Fred and Gareth are fed up with Alexa snoring so they refuse to be on the same side of Christmas hymns Heather Iris came Luke and Michael have no seating preferences how many arrangements of that adults are possible
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:
Number of possibilities = 1 × 2 × 6 × 6 × 24Number of possibilities = 1728Learn more about the factorial function in: https://brainly.com/question/16674303

Let x be the ages of students in a class. Given the frequency distribution f(x) above, determine the following probabilities:.
Probabilities are used to determine the chances of events
The value of the probability P(x < 24) is 0.7895
How to calculate the probability P(x < 24)?This is calculated as:
[tex]P(x < 24) = \frac{n(x < 24)}{Total}[/tex]
So, we have:
[tex]P(x < 24) = \frac{22 + 3 + 5}{22 + 3 + 5 + 4 + 4}[/tex]
Evaluate the sums
[tex]P(x < 24) = \frac{30}{38}[/tex]
Evaluate the quotient
[tex]P(x < 24) = 0.7895[/tex]
Hence, the value of the probability P(x < 24) is 0.7895

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]
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 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.
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

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

Use the graph. Which system of equations is consistent and dependent?
Answer:
Option A
Step-by-step explanation:
A system of equations is consistent when it has at least one solution. If the system is represented by lines it's not consistent if the lines that represent it never intercept each other. Now, if a system is consistent and has an infinite number of solutions then we say that is also dependent. When you graph the equations of a consistent and dependent system those graph must all be the same. Let's use this to find the answer. As you can see the graph of option B is composed of two different lines that we can identify so this is not a dependent system. The same happens with C and D, the graph of each of these systems is composed of two lines instead of one. Now let's see if A is dependent. We have the following equations:
y=2x+1
y-1=2x
If the second equation can be rewritten as the first one then they represent the same line and the system is dependent. Let's take the second equation and add 1 to both sides:
y-1+1=2x+1
y=2x+1
Which is exactly the same equation as the first one. Then these two equations represent the same line. Then the answer is option A.
Hence, the correct answer is Option A

Answer:
$241 should be donated to each charity
Step-by-step explanation:
money donated to each charity = total raised ÷ number of charities
⇒ 5784 ÷ 24 = 241
Answer:
