The cost of a cantaloupe at the supermarket is represented by the equation c = 1.19p. What does the equation mean? If the cantaloupe weighs 3.5 pounds, what will be the price of the cantaloupe?
Let's say c is the cost of the cantaloupe, and that p is how many pounds the cantaloupe weights.
In that case, $1.19 is the amount of money it will cost per pound of cantaloupe.
If the cantaloupe you buy is 3.5 pounds, it will cost you $4.165, but since money is only two decimal places, and since you can only round up when it's a 5 at the end, it becomes $4.17.
In other words, each pound of cantaluope you buy will cost you $1.19, and a cantaloupe that weighs 3.5 pounds will cost you $4.17.

Sophie invested $170 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 % compounded continuously. Wyatt invested $170 in an account paying an interest rate of 3\tfrac{1}{8}3 8 1 % compounded monthly. After 9 years, how much more money would Wyatt have in his account than Sophie, to the nearest dollar?
Answer:
$7
Step-by-step explanation:
Wyatt will have $7 more in his account than Sophie.
What is compound interest?Compound interest is the interest you earn on interest.
Given that, Sophie invested $170 in an account paying an interest rate of [tex]2\tfrac{3}{4}[/tex]% compounded continuously.
Wyatt invested $170 in an account paying an interest rate of [tex]3\tfrac{1}{8}[/tex]% compounded monthly.
We need to find how much more money would Wyatt have in his account than Sophie after 9 years,
For compounded continuously = [tex]Amount = Principal \times e^{rt[/tex]
Sophie =
[tex]Amount = 170 \times e^{0.0275 \times 9[/tex]
A = $217.74
Therefore, Sophie will have $217.74 in her account after 9 years.
For Wyatt,
So, using the formula of CI,
[tex]Amount = Principal(1+r/n)^{nt[/tex]
So,
[tex]= 170(1.0026)^{108[/tex]
A = $225
Therefore, Wyatt will have $225 in his account after 9 years.
The amount Wyatt have more than Sophie = 225-217.74 = $7.26 ≈ $7.
Hence Wyatt will have $7 more in his account than Sophie.

Consider a hypothetical consumer named Hayden who is shopping for bread and brie. The graph with bread and brie on the axes presents the utility‑maximizing combinations of bread and brie that Hayden chooses when the price of bread is $1.00 per loaf and the price of brie is $4.00 and $6.00 per wheel, respectively. The other graph shows Hayden's demand curve for brie.
The two points and associated values in the graph for bread and brie combinations correspond to points A and B in the graph of the demand curve for brie. What are the specific prices and quantities of brie associated with points A and B on Hayden's demand curve?
The graphical relationship of the demand and price of brie are given in the two graphs
At point A, the price is $4.00 and the quantity demanded is 23.84At point A, the price is $6.00 and the quantity demanded is 7.49Reason:
The given parameters are;
The graphs gives the utility-maximizing combinations of bread and brie chosen by Hayden
The price of the loaf = $1.00
The prices of the brie are $4.00 and $6.00 per wheel
Given that as the price increases from $4.00 to $6.00, the quantity
demanded increases, we have;
When the price is $4.00, the quantity of brie demanded 23.84 brie wheels,
and the quantity of bread demanded is 15.9 bread loaves
When the price increases to $6.00, the quantity of brie demanded
decreases to 7.49 brie wheels, while the quantity of bread demanded
increases to 25.2 loaves
Therefore; we have;
At point A, the price is $4.00 and the quantity demanded is 23.84
At point B, the price is $6.00 and the quantity demanded is 7.49

Clarinex-D is a medication whose purpose is to reduce the symptoms associated with a variety of allergies. In clinical trials of Clarinex-D, 5% of patients in the study experienced insomnia as a side effect of taking the medication. Suppose a random sample of 20 patients who took Clarinex-D is obtained and the number of patients who experienced insomnia, X, is recorded. For parts (b)-(d), write a probability statement, such as P(X>3), and calculate the probability (either by hand or using software). Be careful of the wording. Know the difference between less than, at most, etc.
Required:
a. What are the possible values of X?
b. Find the probability that exactly 3 experience insomnia as a side effect?
c. Find the probability 3 or fewer experience insomnia?
d. Between 1 and 4 experience insomnia.
e. Would it be unusual to find 4 or more patients experience insomnia as a side effect?
Using the binomial distribution, it is found that:
a) The possible values of X are between 0 and 20.
b) 0.0596 = 5.96% probability that exactly 3 experience insomnia as a side effect.
c) 0.9842 = 98.42% probability 3 or fewer experience insomnia.
d) 0.639 = 63.9% probability that between 1 and 4 experience insomnia.
e) Since [tex]4 > E(X) + 2.5\sqrt{V(X)}[/tex], it would be unusual to find 4 or more patients experience insomnia as a side effect.
For each patient, there are only two possible outcomes, either they experience insomnia, or they did not. The probability of a patient having experienced insomnia is independent of any other patient, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n trials, with p probability.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
The expected value is:
[tex]E(X) = np[/tex]
The standard deviation is:
[tex]\sqrt{V(X)} = \sqrt{np(1 - p)}[/tex]
If a measure is more than 2.5 standard deviations above the mean, it is considered unusual.
In this problem:
20 trials, thus [tex]n = 20[/tex]5% experience insomnia, thus [tex]p = 0.05[/tex]Item a:
The possible values of X are always between 0 and n, thus in this case, it is between 0 and 20.
Item b:
This probability is P(X = 3), thus:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 3) = C_{20,3}.(0.05)^{3}.(0.95)^{17} = 0.0596[/tex]
0.0596 = 5.96% probability that exactly 3 experience insomnia as a side effect.
Item c:
This probability is [tex]P(X \leq 3)[/tex], given by:
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3)[/tex]
Then:
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 0) = C_{20,0}.(0.05)^{0}.(0.95)^{20} = 0.3585[/tex]
[tex]P(X = 1) = C_{20,1}.(0.05)^{1}.(0.95)^{19} = 0.3774[/tex]
[tex]P(X = 2) = C_{20,2}.(0.05)^{2}.(0.95)^{18} = 0.1887[/tex]
[tex]P(X = 3) = C_{20,3}.(0.05)^{3}.(0.95)^{17} = 0.0596[/tex]
[tex]P(X \leq 3) = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) = 0.3585 + 0.3774 + 0.1887 + 0.0596 = 0.9842[/tex]
0.9842 = 98.42% probability 3 or fewer experience insomnia.
Item d:
This probability is:
[tex]P(1 \leq X \leq 4) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4)[/tex]
Then
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 1) = C_{20,1}.(0.05)^{1}.(0.95)^{19} = 0.3774[/tex]
[tex]P(X = 2) = C_{20,2}.(0.05)^{2}.(0.95)^{18} = 0.1887[/tex]
[tex]P(X = 3) = C_{20,3}.(0.05)^{3}.(0.95)^{17} = 0.0596[/tex]
[tex]P(X = 4) = C_{20,4}.(0.05)^{4}.(0.95)^{16} = 0.0133[/tex]
[tex]P(1 \leq X \leq 4) = P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.3774 + 0.1887 + 0.0596 + 0.0133 = 0.639[/tex]
0.639 = 63.9% probability that between 1 and 4 experience insomnia.
Item e:
[tex]E(X) = np = 20(0.05) = 1[/tex]
[tex]\sqrt{V(X)} = \sqrt{np(1 - p)} = \sqrt{20(0.5)(0.95)} = 0.975[/tex]
[tex]E(X) + 2.5\sqrt{V(X)} = 1 + 2.5(0.975) = 3.44[/tex]

Use substitution to solve each system of equations.
y = 5x -2
3 x- 5y =4
Step-by-step explanation:
y = 5x - 2…Equation 1
3x - 5y = 4…Equation 2
Subtitute value of y to Equation 2 :
3x - 5(5x - 2) = 4
3x - 25x + 10 = 4
-22x + 10 = 4
10 - 4 = 22x
6 = 22x
6/22 = x
3/11 = x
Subtitute value of x to one of Equation :
for example Equation 2…
3x - 5y = 4
3(3/11) - 5y = 4
9/11 - 5y = 4
9/11 - 4 = 5y
(9 - 44)/11 = 5y
(-35)/11 = 5y
(-35)/11 × 1/5 = y
-7/11 = y

Find the measures of the labeled angles.
Answer:
x + 93 = 124
Step-by-step explanation:
4x = x + 93 {Vertically opposite angles are equal}
Subtract 'x' from both sides
4x - x = 93
3x = 93
Divide both sides by 3
x = 93/3
x = 31
x + 93 = 31+ 93 = 124

Lim x-> vô cùng ((căn bậc ba 3 (3x^3+3x^2+x-1)) -(căn bậc 3 (3x^3-x^2+1)))
I believe the given limit is
[tex]\displaystyle \lim_{x\to\infty} \bigg(\sqrt[3]{3x^3+3x^2+x-1} - \sqrt[3]{3x^3-x^2+1}\bigg)[/tex]
Let
[tex]a = 3x^3+3x^2+x-1 \text{ and }b = 3x^3-x^2+1[/tex]
Now rewrite the expression as a difference of cubes:
[tex]a^{1/3}-b^{1/3} = \dfrac{\left(a^{1/3}-b^{1/3}\right)\left(a^{2/3}+a^{1/3}b^{1/3}+b^{2/3}\right)}{\left(a^{2/3}+a^{1/3}b^{1/3}+b^{2/3}\right)} \\\\ = \dfrac{a-b}{a^{2/3}+a^{1/3}b^{1/3}+b^{2/3}}[/tex]
Then
[tex]a-b = (3x^3+3x^2+x-1) - (3x^3-x^2+1) \\\\ = 4x^2+x-2[/tex]
The limit is then equivalent to
[tex]\displaystyle \lim_{x\to\infty} \frac{4x^2+x-2}{a^{2/3}+(ab)^{1/3}+b^{2/3}}[/tex]
From each remaining cube root expression, remove the cubic terms:
[tex]a^{2/3} = \left(3x^3+3x^2+x-1\right)^{2/3} \\\\ = \left(x^3\right)^{2/3} \left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3} \\\\ = x^2 \left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3}[/tex]
[tex](ab)^{1/3} = \left((3x^3+3x^2+x-1)(3x^3-x^2+1)\right)^{1/3} \\\\ = \left(\left(x^3\right)^{1/3}\right)^2 \left(\left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1x\right)\left(3-\dfrac1x+\dfrac1{x^3}\right)\right)^{1/3} \\\\ = x^2 \left(9+\dfrac6x-\dfrac1{x^3}+\dfrac4{x^4}+\dfrac1{x^5}-\dfrac1{x^6}\right)^{1/3}[/tex]
[tex]b^{2/3} = \left(3x^3-x^2+1\right)^{2/3} \\\\ = \left(x^3\right)^{2/3} \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3} \\\\ = x^2 \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3}[/tex]
Now that we see each term in the denominator has a factor of x ², we can eliminate it :
[tex]\displaystyle \lim_{x\to\infty} \frac{4x^2+x-2}{a^{2/3}+(ab)^{1/3}+b^{2/3}} \\\\ = \lim_{x\to\infty} \frac{4x^2+x-2}{x^2 \left(\left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3} + \left(9+\dfrac6x-\dfrac1{x^3}+\dfrac4{x^4}+\dfrac1{x^5}-\dfrac1{x^6}\right)^{1/3} + \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3}\right)}[/tex]
[tex]=\displaystyle \lim_{x\to\infty} \frac{4+\dfrac1x-\dfrac2{x^2}}{\left(3+\dfrac3x+\dfrac1{x^2}-\dfrac1{x^3}\right)^{2/3} + \left(9+\dfrac6x-\dfrac1{x^3}+\dfrac4{x^4}+\dfrac1{x^5}-\dfrac1{x^6}\right)^{1/3} + \left(3-\dfrac1x+\dfrac1{x^3}\right)^{2/3}}[/tex]
As x goes to infinity, each of the 1/x ⁿ terms converge to 0, leaving us with the overall limit,
[tex]\displaystyle \frac{4+0-0}{(3+0+0-0)^{2/3} + (9+0-0+0+0-0)^{1/3} + (3-0+0)^{2/3}} \\\\ = \frac{4}{3^{2/3}+(3^2)^{1/3}+3^{2/3}} \\\\ = \frac{4}{3\cdot 3^{2/3}} = \boxed{\frac{4}{3^{5/3}}}[/tex]

You buy cauliflower at $18 per pound. One portion of cauliflower requires 6 ounces of cauliflower. How much does the cauliflower for one portion cost?
The cauliflower for one portion cost $6.75.
The first step is to convert pounds to ounces. The unit of conversion of pounds to ounces is 1 pound is equivalent to 16 ounces.
1 pound = 16 ounces
Therefore, 16 ounces of cauliflower costs $18.
The cost of one ounce = 18 / 16 = $1.125
The cost of one portion of cauliflower is:
Cost of one ounce x number of ounces in one portion
$1.125 x $6 = $6.75
