Answers
The measurement "500" contains an infinite number of significant figures.
The statement "I counted coins in my coin-collection jar and it turned out 500!!" indicates that the number of coins counted is 500. Since it is a whole number without any decimal places or uncertainties specified, it is considered an exact number. Exact numbers are considered to have infinite significant figures.
The statement implies that the exact count of coins is 500. Since there are no decimal places mentioned and no indication of any uncertainty or approximation, we consider this number to be exact.
Exact numbers, by definition, are considered to have an infinite number of significant figures because they are not subject to the limitations of measurement uncertainties.
Therefore, the measurement "500" contains an infinite number of significant figures.

george's friend clarence, who is even more concerned about consumers, suggests a price ceiling 50% below the monopoly price. at this price, the quantity demanded would be 65 units, and the quantity supplied would be units.
Answers
George's friend Clarence, who is concerned about consumers, suggests implementing a price ceiling that is 50% lower than the monopoly price. With this price ceiling in place, the quantity demanded would increase to 65 units. However, the exact quantity supplied at this new price is not provided in your question.
George's friend Clarence is suggesting a price ceiling, which is a government-imposed limit on how high a price can be charged for a good or service. In this case, the price ceiling is set at 50% below the monopoly price. This means that the price charged for the good or service would be significantly lower than what the monopolistic supplier would typically charge.
At this lower price point, Clarence predicts that the quantity demanded would increase to 65 units, indicating that consumers would be more willing to purchase the product due to its lower price. However, it is unclear what the quantity supplied would be at this price point, as that information is missing from the question.
Overall, George's friend Clarence's suggestion of a price ceiling serves to protect consumers by limiting the monopolistic supplier's ability to charge exorbitant prices and instead promoting a more competitive market.

Consider the following. f(x) = 8x – x2 from x = 0 to x = 4; 2 subintervals (a) Approximate the area under the curve over the specified interval by using the indicated number of subintervals (or rectangles) and evaluating the function at the right-hand endpoints of the subintervals. (See Example 1.) (b) Approximate the area under the curve by evaluating the function at the left-hand endpoints of the subintervals.
Answers
(a) The total area under the curve is nearly equal to 24.
(b) The area under the curve by evaluating the function at the left-hand endpoints of the subintervals is 24.
(a) To approximate the area under the curve of f(x) = 8x - \(x^2\) from x = 0 to x = 4 using 2 subintervals and evaluating the function at the right-hand endpoints of the subintervals.
We can use the right-endpoint rule for approximating definite integrals:
First, we need to find the width of each subinterval:
Δx = (4-0) / 2 = 2
Then, we can evaluate the function at the right-hand endpoints of the subintervals and multiply by the width of each subinterval to find the area of each rectangle:
f(2) = 8(2) - \(2^2\) = 12
f(4) = 8(4) - \(4^2\) = - 8
Area of the first rectangle = f(2)Δx = 12(2) = 24
Area of the second rectangle = f(4)Δx = -8(2) = -16
The total area under the curve is the sum of the areas of the two rectangles:
Total area ≈ 24 + (-16) = 8
(b) To approximate the area under the curve of f(x) = 8x - \(x^2\) from x = 0 to x = 4 using 2 subintervals and evaluating the function at the left-hand endpoints of the subintervals, we can use the left-endpoint rule for approximating definite integrals:
The width of each subinterval is still Δx = 2.
Now, we evaluate the function at the left-hand endpoints of the subintervals and multiply by the width of each subinterval to find the area of each rectangle:
f(0) = 8(0) - \(0^2\) =0
f(2) = 8(2) - \(2^2\) =12
Area of the first rectangle = f(0)Δx = 0(2) = 0
Area of the second rectangle = f(2)Δx = 12(2) = 24
The total area under the curve is the sum of the areas of the two rectangles:

Lisa bought a treadmill for $925. She made a 20% down payment and financed the rest over 18 months. Find the monthly payment if the interest rate was 11%.
Answers
The monthly payment if the interest rate was 11% will be $45.63.
The remaining amount is calculated as,
P = (1 - 0.20) x $925
P = 0.80 x $925
P = $740
The monthly payment is calculated as,
MP = [$740 + ($740 x 0.11)] / 18
MP = $821.4 / 18
MP = $45.63
More about the monthly payment link is given below.
https://brainly.com/question/14064255
#SPJ1
The monthly payment is $49.69.
We have,
The amount of the down payment is:
0.20 x $925 = $185
So the amount financed is:
$925 - $185 = $740
Using the formula for the monthly payment on a loan:
= (Pr(1+r)^n) / ((1+r)^n - 1)
where:
P = principal or amount financed = $740
r = monthly interest rate = 11%/12 = 0.0091667
n = total number of payments = 18
Plugging in the values, we get:
Monthly payment
= ($7400.0091667 x (1+0.0091667)^18) / ((1 + 0.0091667)^18 - 1)
= $49.69 (rounded to the nearest cent)

Answers
The values of sinR = 5/13, cosR = 12/13, tanR = 5/12, sinS = 12/13, cosS = 5/13, tanS = 12/5.
For the right triangle RST in which r=16, s=30, and t=34, find sinR, cosR, tanR, sinS, cosS, and tanS.
Express each ratio as a fraction and as a decimal to the nearest hundredth.
sinR = r/t = 16/34 = 8/17,
cosR = s/t = 30/34 = 15/17,
tanR = r/s = 16/30 = 8/15,
sinS = s/t = 30/34 = 15/17,
cosS = r/t = 16/34 = 8/17,
tanS = s/r = 30/16 = 15/8.
Therefore sinR = 8/17, cosR = 15/17, tanR = 8/15, sinS = 15/17, cosS = 8/17, tanS = 15/8.
The second right triangle is RST, with r = 10, s = 24, and t = 26.2.
sinR = r/t = 10/26 = 5/13,
cosR = s/t = 24/26 = 12/13,
tanR = r/s = 10/24 = 5/12,
sinS = s/t = 24/26 = 12/13,
cosS = r/t = 10/26 = 5/13,
tanS = s/r = 24/10 = 12/5.
Hence the values are;
sinR = 5/13, cosR = 12/13, tanR = 5/12, sinS = 12/13, cosS = 5/13, tanS = 12/5.

The lines represented by the equations y=x+5 and 2y-2x=10 are
Answers
The equations representing the lines, y=x+5 and 2y-2x=10, have the same slope, therefore the lines are parallel.
Recall:
Two lines that are parallel will have the same slope value.Two lines that are perpendicular to each other will have slopes that are negative reciprocal of each other.Equation representing a line in slope-intercept form is: y = mx + b, where m is the slope.Given:
y = x + 5
2y - 2x = 10
The slope of y = x + 5 is 1.
Rewrite 2y - 2x = 10 in slope-intercept form to determine its slope.
2y - 2x = 10
2y = 2x + 10
Divide both sides by 2y = x + 5
Thus, the slope of y = x + 5 (2y - 2x = 10) is also 1.

This applies to compound events that consist of two or more independent events.
For example, suppose you have two dice and you want to know how many possible outcomes there are when you roll them. Each die has 6 possible outcomes, so by the Fundamental Counting Principle, the total number of outcomes for the compound event is 6*6 = 36.

About 90% of young adult Internet users (aged 18 to 29) use social network sites. Suppose that a sample survey contacts an SRS of 1500 young adult Internet users and calculates the proportion ^p in this sample who use network sites
STEP 1: What is the standard deviation of ^p? (Round answer to 4 decimal places)
STEP 2: If the sample size were 6000 rather than 1500, what would be the standard deviation of ^p? (Round answer to 4 decimal places)
Answers
The standard deviation of ^p is 0.012, rounded to 4 decimal places and the standard deviation of ^p with a sample size of 6000 is 0.006, rounded to 4 decimal places.
Given that 90% of young adult Internet users use social network sites, the probability of success in a single trial, denoted by p, is 0.9. The sample size is n = 1500. We want to find the standard deviation of the sample proportion, denoted by σ^p.
The formula for the standard deviation of the sample proportion is:
σ^p = sqrt[p(1-p)/n]
Substituting the values, we get:
σ^p = sqrt[0.9(1-0.9)/1500] = 0.012
Therefore, the standard deviation of ^p is 0.012, rounded to 4 decimal places.
STEP 2:
If the sample size were 6000 rather than 1500, the new sample size would be n = 6000. Using the same formula as before, we get:
σ^p = sqrt[0.9(1-0.9)/6000] = 0.006
Therefore, the standard deviation of ^p with a sample size of 6000 is 0.006, rounded to 4 decimal places.

Company B has an initial fee of $55 and charges an additional $0.60 for every mile driven. For what mileages will Company A charge less than Company B
Answers
Answer:
until 64 miles company A will charge less than company B, they will charge the same price at 65 miles then company B will charge more.
explanation:
94 = 55 + 0.6m
m = (94-55) / 0.6 = 65
The Company A charge less than Company B when the mileage will be more than 65 .
What is equation?
An equation is a mathematical statement that is made up of two expressions connected by an equal sign. For example, 3x – 5 = 16 is an equation.
According to the question
Jenny is going to rent a truck for one day.
Company A :
Charges $94 and allows unlimited mileage.
i.e
Rent of truck for one day = $94
Company B :
Has an initial fee of $55 and charges an additional $0.60 for every mile driven.
Let mile be m
i.e
Rent of truck for one day = $55 + $0.60m
Now, Company A charge less than Company B for mileages
For that we will first find equal point by making both Company's rent equal
Company's A Rent of truck for one day = Company's B Rent of truck for one day
The equation will be :
\(94 = 55 + 0.60m\)
\(39 = 0.6m\)
m = 65
So, at 65 miles both company will rent same but after 65 miles Company B will charge more than Company A .
Hence, The Company A charge less than Company B when the mileage will be more than 65 .

find the arc length indicated by the bolded arc if the radius is 13 in and the central angle is 30 degrees?
Answers
the arc length indicated by the bolded arc with a radius of 13 inches and a central angle of 30 degrees is (13π/6) inches.
To find the arc length indicated by the bolded arc with a radius of 13 inches and a central angle of 30 degrees, follow these steps:
Convert the central angle to radians: Since there are 360 degrees in a full circle and 2π radians in a full circle, you can use the conversion factor (π/180) to convert the central angle from degrees to radians. So, 30 degrees * (π/180) = (30π/180) = (π/6) radians.
Calculate the arc length using the formula: Arc length (L) = radius (r) * central angle (θ), where r is the radius and θ is the central angle in radians. In this case, r = 13 inches and θ = π/6 radians.
Substitute the values into the formula: L = 13 * (π/6)
Solve for L: L = (13π/6)
