Okay I’ll give it my best to explain and solve understand I’m human and if I get this wrong I made a mistake please don’t hate me having said that 96= {x+2} * {x-2} combining like terms x*x (2-2=0) = 92 x^2 and that’s how far I can get you
Answer:
x = 24.
Step-by-step explanation:
Set 96 = (x+2)+(x+2) + (x-2)+(x-2). Then simplify: 96 = (2x+4) + (2x-4). Simplify again XD: 96 = 4x (since +4 and -4 cancel out to get 0) . Divide 96 by 4 and your final answer should be 24 Wow..that was pretty slight lol :D

Find the median and the upper/lower quartiles
Rearrange the data in ascending order
33, 36, 37, 38, 41, 42, 46, 49, 50, 50, 51, 52, 53, 54
The median is the middle value of the data or if there is no exact value at the middle then it is the average of the 2 values either side of the middle
Here the median is between 46 and 49
median = [tex]\frac{46+49}{2}[/tex] = 47.5
The upper quartile is the middle value of the data to the right of the median
[tex]Q_{3}[/tex] = 51
The lower quartile is the middle value of the data to the left of the median
[tex]Q_{1}[/tex] = 38
The minimum value = 33
The maximum value = 54
The lower quartile is the left side of the box plot
The upper quartile is the right side of the box plot
The median is located inside the box plot
The corresponding box plot is B

Bea's uncle said that if you subtract 15 from 3 times his age you would get 60. Be a wrote this equation: 3x- 15= 60. how old is Bea's uncle? PLZ I NEED THIS ANSWER RIGHT AWAY ITSFOR A TEST AND I NEED HELPPPP
Answer: Bea's uncle is 25 years old.
Step-by-step explanation:
Given the equation [tex]3x- 15= 60[/tex], we can say that the variable "x" represents the age of Bea's uncle. Then to find his age, we need to solve for "x":
We must add 15 to both sides of the equation:
[tex]3x- 15+(15)= 60+(15)\\3x=75[/tex]
Now we need to divide both sides of the equation by 3:
[tex]\frac{3x}{3}=\frac{75}{3}\\\\x=25[/tex]

After dinner, your aunt serves slices of apple pie. Would you rather have a slice with a central angle equal to
(a) one radian
(b) 60 degrees?
You must choose (a) or (b) and explain why you chose one over the other.
Answer:
b) 60 degrees because one radian is approximately 57.29 degrees so you'd probably go with 60 because you'd want more pie
Answer:
b) should be preferred
Step-by-step explanation:
Given that after dinner, your aunt serves slices of apple pie.
Central angle of a circle determines the area of the sector
Slice of apple pie here represents the sector area.
Area of a sector = [tex]\frac{x}{360} (\pi r^2)[/tex]
i.e. when central angle increases area also increases.
Comparing one radian and 60 degrees, we get
60 degrees = [tex]\frac{60}{180}\pi =\frac{3.14}{3} \\=1.0467[/tex] radians
Since 60 degrees is more
b) should be preferred
A bag contains 2 red marbles and 4 green marbles. Two marbles are drawn at random. One marble is drawn and not replaced. Then a second marble is drawn. What is the probability that the first marble is green and the second one is red?
Answer:
Step-by-step explanation:
Red = 2
Green = 4
P(G) = 4/6
P(R) = 2/5 (remember that 1 green marble is green. The total left is 5 so the 5 is not a typo)
P(G then R) = 4/6 * 2/5
P(G then R) = 2/3 * 2/5
P(G then R) = 4/15

PLEASE HELP!!! The total area of fictional Puget Loud, near Seapple, Washington, can be roughly estimated using a rectangular shape that is 110 miles long and 15 miles wide. In Puget Loud, orcas require approximately 5 mi² of territory per animal. Based on this information, how many orcas could live in Puget Loud? Show your work and place a box around your answer.
Answer:
[tex]330\ orcas[/tex]
Step-by-step explanation:
step 1
Find the total area of fictional Puget Loud
The area of the rectangular shape is
[tex]A=110*15=1,650\ mi^{2}[/tex]
step 2
Divide the total area by 5 mi² of territory per animal to find the number of orcas that could live in Puget Loud
[tex]1,650/5=330\ orcas[/tex]
Final answer:
To determine how many orcas could live in Puget Loud, calculate the total area (Length × Width) and divide it by the amount of space required per orca (5 mi²). The calculation gives us 330 orcas.
Explanation:
To estimate the number of orcas that could live in Puget Loud, we first need to calculate the total area of Puget Loud. We do this by multiplying the length by the width of the rectangular region.
Total area of Puget Loud = Length × Width
Total area of Puget Loud = 110 miles × 15 miles
Total area of Puget Loud = 1650 square miles
Next, we need to divide the total area of Puget Loud by the territory required per orca. Each orca requires approximately 5 square miles.
Number of orcas = Total area / Territory per orca
Number of orcas = 1650 mi² / 5 mi² per orca
Number of orcas = 330
Therefore, Puget Loud could potentially support 330 orcas.

One side of a triangle measures 10 inches. Which could be the measures of the other 2 sides of the triangle?
A. 3 in & 8 in
B. 4 in & 6 in
C. 5 in & 15 in
D. 6 in & 18 in
Answer:
B. 4 and 6 in
Step-by-step explanation:
The triangle inequality rule states: the length of a side of a triangle is less than the sum of the lengths of the other two sides and greater than the difference of the lengths of the other two sides.
So for the first qualification, we can eliminate A, C, and D. Therefore the answer is B, 4 & 6 in
To check whether the given side-lengths can form a triangle, we have to use the Triangle Inequality Theorem. This theorem states that for any triangle, the sum of the lengths of any two sides must be greater than the length of the third side.
Let's apply this theorem to each pair of side-lengths given in the options along with the third side of 10 inches:
Option A:
Sides are 3 in, 8 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 3 + 8 > 10 (which is true, since 11 > 10)
- 3 + 10 > 8 (which is true, since 13 > 8)
- 8 + 10 > 3 (which is true, since 18 > 3)
Since all three conditions are satisfied, option A can form a triangle.
Option B:
Sides are 4 in, 6 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 4 + 6 > 10 (which is not true, since 10 is not greater than 10)
- 4 + 10 > 6 (which is true, since 14 > 6)
- 6 + 10 > 4 (which is true, since 16 > 4)
Since not all conditions are satisfied (specifically, the sum of the two smaller sides is not greater than the third side), option B cannot form a triangle.
Option C:
Sides are 5 in, 15 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 5 + 15 > 10 (which is true, since 20 > 10)
- 5 + 10 > 15 (which is not true, since 15 is not greater than 15)
- 15 + 10 > 5 (which is true, since 25 > 5)
Since not all conditions are satisfied, option C cannot form a triangle.
Option D:
Sides are 6 in, 18 in, and 10 in. According to the Triangle Inequality Theorem, we need to check if:
- 6 + 18 > 10 (which is true, since 24 > 10)
- 6 + 10 > 18 (which is not true, since 16 is not greater than 18)
- 18 + 10 > 6 (which is true, since 28 > 6)
Since not all conditions are satisfied, option D cannot form a triangle.
Therefore, the only option that satisfies the Triangle Inequality Theorem and thus can be the measures of the other two sides of the triangle with one side measuring 10 inches is:
Option A: 3 in & 8 in.
1. The table shows values of a function . What is the average rate of change of over the interval from x = 5 to x = 9? Show your work.
x 4 5 6 7 8 9 10
8 10 11 14 18
Answer:
Average change of rate = 4
Step-by-step explanation:
The average rate of change is going to be the final value mines the initial value, divided by the change in the input of the function.
Average change of rate = (14 - (-2)) / 9 - 5 = 16/4 = 4
To calculate the average rate of change of a function from x = 5 to x = 9, one would need the function values at these points. The change in function values divided by the change in x values gives the average rate of change.
Explanation:The average rate of change of a function over an interval is calculated by taking the difference in function values at the end points of the interval and dividing by the difference in the x-values.
In this case, to find the average rate of change of f(x) over the interval from x = 5 to x = 9, you look at the table to find the values of f(5) and f(9). Unfortunately, the table is incomplete, so we cannot find the exact values of f(5) and f(9). Assuming you have the complete table, with f(5) and f(9) known, the process would be:
Subtract the value of the function at x = 5 from the value of the function at x = 9 to get the change in y, or ∆y.Subtract 5 from 9 to find the change in x, or ∆x.Divide ∆y by ∆x to find the average rate of change.If f(5) = a and f(9) = b, the average rate of change from x = 5 to x = 9 would be (b - a)/(9 - 5).
The total cost in dollars to buy uniforms for the players on a volleyball team can be found using the function c= 34.95u +6.25, where u is the number of uniforms bought. If there are at least 8 players but not more than 12 players on the volleyball team, what is the domain of the function for this situation
The domain of the function for this situation is [8, 12].
Explanation:The given function is c = 34.95u + 6.25, where c represents the total cost in dollars and u represents the number of uniforms bought.
To find the domain of the function for this situation, we need to determine the range of values that u can take within the given restrictions.
The question states that there should be at least 8 players but not more than 12 players on the volleyball team.
Therefore, the domain of the function is the set of numbers greater than or equal to 8 and less than or equal to 12. In interval notation, the domain can be represented as [8, 12].
Final answer:
The domain of the function c = 34.95u + 6.25 for the number of uniforms needed by a volleyball team is {8, 9, 10, 11, 12}, which corresponds to the number of players on the team, ranging from 8 to 12.
Explanation:
The function c = 34.95u + 6.25 represents the total cost to buy uniforms, where u is the number of uniforms. To determine the domain of this function based on the number of players, we note that there are at least 8 players and no more than 12 players on the volleyball team. Therefore, the number of uniforms (and hence the value of u) can range from 8 to 12, inclusive.
The domain of the function in this context is the set of whole numbers from 8 to 12. So, the domain is {8, 9, 10, 11, 12}.

If a+b/a =3, t+a/a =5, what is the value of b/t ?
Answer: b/t = 1/2 (or) 0.5
Step-by-step explanation:
a+b/ a =3
a+b = 3a
b = 3a-a
b = 2a
t+a/a = 5
t+a = 5a
t = 5a-a
t = 4a
b/t = 2a /4a
= 1/2
The value of b/t is 1/2.
We have,
(a + b) / a = 3 ...(Equation 1)
(t + a) / a = 5 ...(Equation 2)
Let's solve Equation 1 for b:
(a + b) / a = 3
Multiplying both sides by a:
a + b = 3a
Subtracting a from both sides:
b = 3a - a
b = 2a ...(Equation 3)
Now, let's solve Equation 2 for t:
(t + a) / a = 5
Multiplying both sides by a:
t + a = 5a
Subtracting a from both sides:
t = 5a - a
t = 4a ...(Equation 4)
Now, let's substitute these values into the expression b/t:
b/t = (2a) / (4a)
b/t = 2a / 4a
b/t = 1/2
Therefore, the value of b/t is 1/2.

Answer:
1/10
Step-by-step explanation:
Okay so, if you convert the fractions so they're both over ten, you have 2/10 and 7/10, adding those together you get 9/10 of the student population; leaving 1/10 of the students left. So the answer is 1/10 of the students ride the bus to school.
(Unless I completely read this question wrong lol, hope this helped some.)
Final answer:
In Ms. March's class, 7/10 of students walk and 1/5 ride bikes, leaving 1/10 of the class to ride on the school bus.
Explanation:
In Ms. March's class, 7/10 of the students walk to school, and another 1/5 of the students ride their bikes. To find out what fraction of the class rides on the school bus, we first need to add the fractions of students walking and riding bikes, and then subtract this total from 1 (which represents the whole class).
Add the fractions of students walking and biking: 7/10 + 1/5 = 7/10 + 2/10 = 9/10.
Subtract this total from 1 to find the fraction of students who ride the bus: 1 - 9/10 = 1/10.
Therefore, 1/10 of the class rides on the school bus.

The coach has 3 positions to fill on his basketball team. There are 9 students interested in being on the team. How many combinations of the three positions can he choose?
Answer:
84
Step-by-step explanation:
To find this, we need to understand the combination formula.
If we have n items and we want to choose r at a time, we use the formula:
[tex]nCr=\frac{n!}{(n-r)!*r!}[/tex]
Where n! means n(n-1)(n-2)....
So we want 9C3, plugging them into the formula and doing some arithmetic, we have:
[tex]nCr=\frac{n!}{(n-r)!*r!}\\9C3=\frac{9!}{(9-3)!*3!}\\=\frac{9!}{6!*3!}\\=\frac{9*8*7*6!}{6!*3*2*1}\\=\frac{9*8*7}{3*2*1}\\=84[/tex]

Answer:
# The transformation of f(x) to be g(x) is
- Reflected across the x-axis
- Translated 7 units to the left
- Translated 6 units up
# The transformation of f(x) to be g(x) is
- Reflected across the y-axis
- Translated 7 units down
Step-by-step explanation:
* Lets revise some transformation rules
* Lets talk about the transformation
- If the function f(x) reflected across the x-axis, then the new
function g(x) = - f(x)
- If the function f(x) reflected across the y-axis, then the new
function g(x) = f(-x)
- If the function f(x) translated horizontally to the right
by h units, then the new function g(x) = f(x - h)
- If the function f(x) translated horizontally to the left
by h units, then the new function g(x) = f(x + h)
- If the function f(x) translated vertically up
by k units, then the new function g(x) = f(x) + k
- If the function f(x) translated vertically down
by k units, then the new function g(x) = f(x) – k
* Lets solve the problems
# f(x) = 2^x ⇒ g(x) = -(2)^(x + 7) + 6
- There is a -ve sign in-front of the 2
∵ f(x) will be -f(x)
∴ f(x) will reflect across the x-axis ⇒ (1)
- The power x becomes x + 7
∵ -f(x) will be -f(x + 7)
∴ -f(x) will translate 7 units to the left ⇒ (2)
- after that -f(x + 7) add by 6
∴ -f(x + 7) will translate 6 units up ⇒ (3)
- From (1) , (2) , (3)
∴ The transformation of f(x) to be g(x) is
- Reflected across the x-axis
- Translated 7 units to the left
- Translated 6 units up
# f(x) = ㏒(x) ⇒ g(x) = ㏒(-x) - 7
- The (x) will be (-x)
∵ f(x) will be f(-x)
∴ f(x) will reflect across the y-axis ⇒ (1)
- after that f(-x) subtracted by 7
∴ f(-x) will translate 7 units down ⇒ (2)
- From (1) , (2)
∴ The transformation of f(x) to be g(x) is
- Reflected across the y-axis
- Translated 7 units down
* For more understand look to the attached graphs
# First function:
- f(x) is the red
