Answer:
[tex]P(x) = -0.25x^2 + 42x - 90[/tex]
Step-by-step explanation:
Given
[tex]C(x) = -17x + 90[/tex]
[tex]R(x) =- 0.25x^2 + 25x[/tex]
Required
Determine the profit function.
Profit function is calculated as thus:
[tex]P(x) = R(x) - C(x)[/tex]
So, we have:
[tex]P(x) = -0.25x^2 + 25x -(-17x + 90)[/tex]
[tex]P(x) = -0.25x^2 + 25x + 17x - 90[/tex]
[tex]P(x) = -0.25x^2 + 42x - 90[/tex]

S.The number of hours spent in an airplane on a single flight is recorded on a dot plot. The mean is 5 hours and the standard deviation is approximately 5.82 hours. The median is 4 hours and the IQR is 3 hours. The value 26 hours is an outlier that should not have been included in the data. 6 8 10 12 14 16 188 20 22 24 26 28 number of hours spent in an airplane When the outlier is removed from the data set a. What is the mean? b. What is the standard deviation? 1-3 C. What is the median? d. What is the IQR? (From Unit 1, Lesson 14.)
Answer:
mean: 3.5
standard deviation: 3
median: 3.5
IQR: 3
Step-by-step explanation:
I mean all you gotta do is look at the table that is shown and since the graph is symmetrical the median and mean would be at the center and the standard deviation is basically how far away most of the data points is going to be from the center and the IQR is easy you get the Q1 and Q3 then subtract then and you get 3. So ya.

Find 3 consecutive odd integers such that 1 less than 3 times the larger is equal to the sum of twice the first and twice the second number. Please explain why and with steps.
Answer:
7, 9, 11
Step-by-step explanation:
If x is the smallest of the integers, then x+2 is the next consecutive odd integer, and x+4 is the largest odd integer.
1 less than 3 times the largest is equal to the sum of twice the first and twice the second.
3(x+4) − 1 = 2x + 2(x+2)
3x + 12 − 1 = 2x + 2x + 4
3x + 11 = 4x + 4
7 = x
The integers are 7, 9, and 11.

Answer:
$9,635.00
Step-by-step explanation:
41 bracelets×$235.00=$9,635.00
First can I just say, those are some expensive jewelry!
l
Step-by-step explanation:
The amount of bracelets that she sold last month, (Saturday + Sunday) is 41. So last month she sold 41 bracelets.
Each bracelet cost $235 so we have to multiply to amount of money one bracelet cost, times how many she sold.
$235 x 41 = $9635
She made $9635 by selling bracelets last month.
Question: -3x – 10 = 32
Answer:
x = -14
Step-by-step explanation:
The first thing you are trying to do is get the x alone. so first you will look at 10 and do the opposite of the sign that you have. So you would take the -10 and make it +10. you would solve -10 + 10 and 32 + 10 because whatever you do to one side you do to the other. -10 +10= 0 and 32+10 = 42. Your equation now is -3x=42. we do not put -3x+0=42 because zero does not have a value. From here we would look at the -3x and do the opposite sign, which means dividing. whenever a number is next to x or any variable it is multiplication. For example, 7x is the same as 7*x. The opposite of multiplication is division. so we would do -3x/-3. We do 42/-3 because whatever we do to one side we do to the other. On the left side we are left with x then you add the equal sign and the quotient of 42/-3.
Answer: x = -14

Maya is taking her friends to a concert. Each ticket costs
$25, and souvenir T-shirts are $12 each. There is a $4
service fee for the entire purchase. She has $130. If she
buys 3 tickets, what is the maximum number of T-shirts
she can buy?
If x = number of tickets and y= number of T-shirts, which of the following
inequalities could you use to answer the problem?
Answer:
C. 25x+12y+4≤ 130
Step-by-step explanation:
Each ticket cost $25, so x would be the number of tickets she has to buy.
25x
Each T-shirt cost $12, so y would be the number of T-shirts she can buy.
12y
And since there is an service fee for the entree purchase, that's another $4.
+4
The cost of everything has to be less than $130, so the equation would be:
25x+12y+4≤ 130

-1+30x+24=6(5x+4)
???
Answer:
No solution.
Step-by-step explanation:
Write the expression, combine like terms, and distribute.
-1+30x+24=6(5x+4)
30x+23=30x+24
Get rid of the variable first because they're both 30x (it makes it a lot easier).
30x+23=30x+24
-30x -30x
23=24
23 is not equal to 24. When this happens, it means there is no solution, and that's just the answer.

All of the interior angles of a triangle equate to 180.
the figure below is a rhombus y = ?
Answer:
y = 28°
Step-by-step explanation:
The opposite angles of a rhombus are congruent.
The diagonal divides the rhombus into 2 isosceles triangles, as all sides are congruent.
Thus the triangle containing base angles y and w has vertex = 124°
Since the triangle is isosceles then the base angles are congruent , thus
y = [tex]\frac{180-124}{2}[/tex] = [tex]\frac{56}{2}[/tex] = 28°
