Answer:
A. (Pay as you go) $120 B. (Regular deal) $90 C. (All-in-one price!) $100 D. The "Regular deal" option would be the least expensive for Carl.
Step-by-step explanation:
If Carl does the "Pay as you go" option he would be charged $6 each time. If he works out 20 times a month, we can multiply 20 by 6 to get a total of $120 for that option.
If Carl does the "Regular deal" option he would be charged $50 + an additional $2 for each time he works out. From there, we can get the equation 2x + 50 where x is the amount of time he works out. If we plug in 20 for x (as he works out 20 times a month), we get 2(20) + 50 which equals a total of $90 for that option.
If Carl does the "All-in-one Price!" option he would be charged $100 for the whole month meaning he has unlimited use of the gym with no extra charge besides the $100.
The cheapest option is the "Regular deal" option as it charges $90 compared to the $100 for the "All-in-one Price!" option & the $120 for the "Pay as you go" option.

The estimate obtained from a sample of which of the following sizes would most likely be closest to the actual parameter value of a population?
To obtain an estimate of a parameter of a population, we use confidence intervals.
Confidence intervals:
The larger the sample size, the closest the parameter estimate is to the value of the population, as the margin of error of confidence intervals is inversely proportional to the sample size, that is, a greater sample leads to a smaller margin of error.
Thus, you should select the highest sample size in the options.

Step-by-step explanation:

a baker is building a rectangular solid box from cardboard to be able to safely deliver a birthday cake. The baker wants the volume of the delivery box to be 224 cubic inches. If the width of the delivery box is 3 inches longer than the length and the height is 4 inches longer than the length, what must the length of the delivery box be?
3 inches
7 inches
8 inches
4 inches
The length of the rectangular delivery box must be equal to 4 inches.
Let the length of the box be L.
Let the width of the box be W.
Let the height of the box be H.
Given the following data:
Volume of box = 224 cubic inches.Translating the word problem into an algebraic expression;
[tex]W = 3 + L[/tex] ......equation 1
[tex]H = 4 + L[/tex] ......equation 2.
Mathematically, the volume of a rectangular solid is given by the formula;
[tex]Volume = length * width * height[/tex] .....equation 3.
Substituting the values into equation, we have;
[tex]224 = L * (3 + L) * (4 + L)\\\\224 = (3L + L^{2})* (4 + L)\\\\224 = 12L + 3L^{2} + 4L^{2} + L^{3} \\\\224 = 12L + 7L^{2} + L^{3}[/tex]
Rearranging the polynomial, we have;
[tex]L^{3} + 7L^{2} + 12L - 224 = 0[/tex]
We would apply the remainder theorem to solve the polynomial.
According to the remainder theorem, if a polynomial P(x) is divided by (x - r) and there is a remainder R; then P(r) = R.
When x = 3
[tex](x - 3) = 0\\x = 3[/tex]
[tex]P(3) = 3^{3} + 7(3^{2}) + 12(3) - 224\\\\P(3) = 27 + 7(9) + 36 - 224\\\\P(3) = 27 + 63 + 36 - 224 = -98 \neq 0[/tex]
We would try with 4;
[tex]P(4) = 4^{3} + 7(4^{2}) + 12(4) - 224\\\\P(4) = 64 + 7(16) + 48 - 224\\\\P(4) = 64 + 112 + 48 - 224\\\\P(4) = 224 - 224 = 0[/tex]
Therefore, 4 is one of its roots.
Hence, the length of the rectangular delivery box must be equal to 4 inches.

Answer:
Step-by-step explanation:
Never saw a problem presented in this way in all my years of teaching calculus. But I'm thinking that we need to sub that given expression for m into the equation for y and get everything into y in terms of x in order to find the derivative. I see no other way that makes sense. Can't find the derivative of y in terms of x if there's an m in there. Making that substitution:
[tex]y=\frac{5}{1+(3x+1)^2}[/tex] which simplifies to
[tex]y=\frac{5}{1+9x^2+6x+1}[/tex] and a bit more to
[tex]y=\frac{5}{9x^2+6x+2}[/tex] and now we're ready to find the derivative. Using the quotient rule:
[tex]y'=\frac{(9x^2+6x+2)(0)-[5(18x+6)]}{(9x^2+6x+2)^2}[/tex] which simplifies to
[tex]y'=\frac{-90x-30}{(9x^2+6x+2)^2}[/tex] or, equally:
[tex]y'=-\frac{90x+30}{(9x^2+6x+2)^2}[/tex]

EH is median
FH = HG
6x - 1.1 = 4x + 1.3
Add 1.1 to both sides
6x = 4x + 1.3 + 1.1
6x = 4x + 2.4
Subtract 4x from both sides
6x - 4x = 2.4
2x = 2.4
Divide both sides by 2
x = 2.4/2
x = 1.2
FH = 6x - 1.1
= 6*1.2 - 1.1
= 7.2 - 1.1
= 6.1
FG = 6.1 + 6.1 = 12.2

There are 9 classes of 25 students each, 4 teachers, and 2 times as many parent volunteers as teachers.
Each bus holds a total of 45 people.
What is the least number of buses needed for the field trip?
the answer Is found in the question
The least number of buses required for the trip will be 5 buses.
What is the Unitary method?It is a method where we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
First, let us make a note of the information we have. There are 5 ice-creams. 5 ice-creams cost $125.
Step 1: Let’s find the cost of 1 ice cream. In order to do that, divide the total cost of ice-creams by the total number of ice-creams. The cost of 1 ice-cream = Total cost of ice-creams/Total number of ice-creams = 125/5 = 25. Therefore, the cost of 1 ice cream is $25.
Step 2: To find the cost of 3 ice creams, multiply the cost of 1 ice cream by the number of ice-creams. The cost of 3 ice-creams is cost of 1 ice-cream × number of ice-creams = 25 × 3 = $75. Finally, we have the cost of 3 ice-creams i.e. $75.
Total number of classes = 9
Number of students in each class = 25
Number of teachers = 4
Number of chaperones = Double of teacher
Bus hold = 45 people
A total number of students.
= 9 × 25
= 225
A number of chaperones.
= 4 × 2
= 8
Total people = 225 + 8 + 4 = 237
Least number of buses required for trip = Total people / Bus hold
= 237 / 45
= 5.266

Betty sets up a lemonade stand and charges $1 per glass. It cost her $50 to set up the stand. Which function gives the profit, p, she makes by selling g glasses of lemonade?
The number of glasses of lemonade, g, that Betty needs to sell to make a profit, p, if the setup cost her $50 is given by the function p(g) =
.
Answer:
1g - 50 = p(g)
Step-by-step explanation:
The profit function is,
⇒ p(g) = g - 50
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
Betty sets up a lemonade stand and charges $1 per glass.
It cost her $50 to set up the stand.
And, We have to find the function gives the profit, p, she makes by selling g glasses of lemonade.
Now, The number of glasses of lemonade sold = g,
And, A profit, p by function p(g)
Setup cost = $50
Since, Charges for 1 glass = 1 $
Hence, Charges for g glasses = 1.g = $g
Here, The cost = $50
Hence, Profit = $g - 50
⇒ p(g) = g - 50
Therefore, The profit function is,
⇒ p(g) = g - 50

Madeline is renting bowling shoes for $3.50 every time she goes bowling. She could get a good pair of bowling shoes for $68.
If she goes once every two weeks during the year, would it be less expensive to rent or buy?
A Buy
B Rent
Answer:
rent would be cheaper
Step-by-step explanation:
1.50 x 26 = $39 or $48 for a pair
it would be nine dollars cheaper to rent than to buy
Iit would be less if she rent the shoes.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given that Madeline is renting bowling shoes for $3.50 every time she goes bowling.
she goes once every two weeks during the year.
In a year there are 52 weeks.
As she is going once every two weeks during the year, so let us divide 52 by 2, 52/2=26
Rent for each bowling is 3.50
So for 26 times it would be 26×3.50
If she goes once every two weeks during the year, then the rent amount will be $91.
As She could get a good pair of bowling shoes for $68.
91 is greater than 68
So, it would be less expensive if she rent the shoes.

How do I solve this problem? The trouble that I have is evaluating if 2^∞ or ∞³ is larger?
For large enough x, exponential functions like 2ˣ will always dominate a polynomial of any degree. This is to say the denominator will always be larger than the numerator (again, for sufficiently large x). So the limit in this case would be 0. (I'll leave a link in comments to a variety of answers regarding this detail.)
But if you've been introduced to L'Hopital's rule: we have
[tex]\displaystyle \lim_{x\to\infty}\frac{5x^3+10}{6\times2^x-1} = \lim_{x\to\infty}\frac{15x^2}{6\ln(2)\times2^x} = \lim_{x\to\infty}\frac{30x}{6\ln^2(2)\times2^x} = \lim_{x\to\infty}\frac{30}{6\ln^3(2)\times2^x} = \frac1\infty = 0[/tex]
