What is the asymptote of the function?A line that a curve approaches but never touches is an asymptote. The graph of a function converges to a line known as an asymptote, in other words. When graphing functions, asymptotes are usually not necessary to be drawn. The curve must not contact the asymptote when we graph them using dotted lines (imaginary lines). As a result, the asymptotes are merely made-up lines. When either the value of x or y tends to or -, the distance between the asymptote of a function, y = f(x), and its graph is close to zero.
Option A is correct as according to the option A: - B(w)= [tex]\frac{120w}{150+w^{2} }[/tex], w=0.
On putting the value of w=0 in above function implies B(w)=0.
Hence, number of boxes of cereals sold is 0 after 0 weeks.
Option C is correct as function B(w) is decreasing function after reaching its maxima according to graph.
Option E is correct as B(w)= [tex]\frac{120w}{150+w^{2} }[/tex], if w>0

The number of unique orders that Gabriel can arrange for the new flavors of his favourite snak is 6..
Permutation:The term permutation refers to the mathematical calculation of the number of ways a given set can be arranged. Simply put, permutation is a word that describes the number of ways things can be ordered or arranged. With permutations, the order of placement is important.
P(n,r) = n!/(n-r)!
where n --> total items in the set;
r --> items taken for the permutation;
"!" --> denotes taking the factorial
We have given that,
total possible flavours of Gabriel's favorite snack = 3
He wants to try each of the new flavors one after the other.
We have to calculate the number of ways Gabriel can arrange the new flavors .
For this Use the permutation formula,
ⁿPᵣ = n!/(n-r)!
here , n = 3 , r = 3 then,
P (3,3) = 3!/(3 − 3)!
= 3!/0!
As we know that 0! = 1 so, P(3,3) = 3!
= 3×2×1 (because n! = n(n-1)(n-2)---3.2.1 )

a researcher wants to test the claim that the proportion of men who watch television regularly is greater than the proportion of women who watch television regularly. she finds that 56 of 70 randomly selected men and 47 of 85 randomly selected women report watching television regularly. a 95% confidence interval for the difference in population proportions is (0.10581, 0.38831). which of the statements gives the correct outcome of the researcher's test of the claim?
Therefore , the answer is the confidence interval is positive, the researcher can conclude there is a greater proportion of men than women who watch television regularly.
Confidence interval definition:A confidence interval in frequentist statistics is a range of estimates for an unobserved parameter. The most common confidence level for computing confidence intervals is 95%, however other levels, including 90% or 99%, are sporadically employed.
Here,
Assuming that the confidence interval's lower and upper bounds are both positive and that it does, then one of the proportions must be larger than the other as the confidence interval's range corresponds to the difference in proportions. Men watch television more frequently than women do (56/70 vs. 47/85, according to a quick calculation of the proportions).
The reply is "D" The researcher can infer that more men than women routinely watch television because the confidence interval is positive.

Aaron's dad has a pickup truck and his mom has an SUV. Last week, his dad traveled 84 miles in the pickup truck on 4 gallons of gas. His mom traveled 72 miles in the SUV on 3 gallons of gas. How many more miles per gallon did the SUV get than the truck?
Write your answer as a decimal or a whole number.
Answer:
To find out how many miles per gallon the truck got, we can divide the number of miles it traveled by the number of gallons of gas it used: 84 miles / 4 gallons = <<84/4=21>>21 miles/gallon.
To find out how many miles per gallon the SUV got, we can divide the number of miles it traveled by the number of gallons of gas it used: 72 miles / 3 gallons = <<72/3=24>>24 miles/gallon.
To find out how many more miles per gallon the SUV got than the truck, we can subtract the number of miles per gallon the truck got from the number of miles per gallon the SUV got: 24 miles/gallon - 21 miles/gallon = <<24-21=3>>3 miles/gallon.

the distribution of cholesterol levels in teenage boys is approximately normal with mean of 170 and standard deviation 25 (source: u.s. national center for health statistics). levels above 200 warrant attention. find the probability that a teenage boy has a cholesterol level greater than 200. group of answer choices
The probability that a teenage boy has a cholesterol level greater than 200 is 0.11507.
Let the distribution of teenage boys' cholesterol levels be x
According to the question,
X follows a Normal distribution with
mean = 170
Standard deviation = 25
Hence, the variance = 25² = 625.
Hence X ~ N(170,25)
Now we need to find P(X>200)
= 1 - P(X<200)
Now to find this we need to convert the problem to a standard normal distribution
for this, we use the formula
P(X<x) = P(Z<x-mean/sd)
Therefore,
P(X<200)
= P(Z<(200 - 170)/25)
= P(Z<30/25)
= P(Z<1.2)
According to Z table,
P(Z<1.2)
= 0.88493
Hence, P(X>200)
= 1 - 0.88493

Mrs. Robinson bought a novel at the bookstore on sale for 20% off its regular price of $29.99. Mr. Chang bought the same novel at a different bookstore for 10% off its regular price of $25. which person received the better discount? Explain.
Answer: Mrs. Robinson
Step-by-step explanation:
Let's find Mrs. Robinson first
100% - 20% = 80% or 0.8
29.99 times 0.8% = $24
29.99 -24 = $5.99 off
Now Let's find Mr.Chang
100% - 10% = 90% or 0.9
25 times 0.9% = $22.50
25 - 22.50 = $2.50 off
So Mrs. Robinson received a better discount!
mary drove 156156 miles at a constant rate. if she had driven 99mi/h faster, she could have reduced her driving time by 4545 minutes. find the rate at which she actually drove.
The speed at which Marry was initially driving was 13 miles per hour and with that speed Marry drove 156 miles.
Given, Marry drove 156 miles at a constant rate.
If she had driven 99 miles/hour faster, she could have reduced her driving time by 45 minutes.
we have to find the speed at which Marry was driving.
Let the speed be, v
On using the distance formula, we get
Distance = Speed × Time
156 = vt
If she drive 99 miles/hour faster then her time reduced by 45 min.
156 = (v + 99)(t - 3/4)
156 = 156 + 99t - 3/4v - 297/4
396t = 3v + 297
396t = 468/t + 297
On solving the quadratic equation, we get
t = 12
and v = 13
So, the speed of marry was 13 miles per hour.
Hence, Initially the speed of marry was 13 miles per hour and with that speed Marry drove 156 miles.

The value of the given car after 7 years will be $2880 which has been decreasing by 20% every three years.
A car is currently $6,000 and has been decreasing by 20% every three years.
After 7 years, the car will have decreased in value by 7 / 3 = 2 full cycles of 20%.
Each cycle decreases the value of the car by 20/100 × $6,000 = $1200.
After two cycles, the value of the car will be :
$6,000 - 2 × $1,200 = $3,600.
After 7 years, the car will have decreased in value by an additional :
$3,600 × 20/100 = $720.
