Answer:
The most reasonable estimate for the number of Sunset Park Food Festival attendees whose favorite type of burger is a sausage bacon cheeseburger is 760.
Step-by-step explanation:
Assume that Bob's Burgers provides two types of burgers:
Bacon cheeseburgers (B)Sausage bacon cheeseburger (S)Of the random sample of N = 70 attendees, the number of people who said that bacon cheeseburgers were their favorite type of burgers is 32.
Then the number of people who said that sausage bacon cheeseburgers were their favorite type of burgers is, n (S) = 70 - 32 = 38.
Compute the probability that a randomly selected attendee like sausage bacon cheeseburger as follows:
[tex]P(S) = \frac{n(S)}{N}=\farc{38}{70}=0.543[/tex]
It is provided that there are 1400 Sunset Park Food Festival attendees.
Let the random variable X be defined as the number of attendee who likes sausage bacon cheeseburgers.
Then the random variable X will follows a Binomial distribution with parameter n = 1400 and p = 0.543.
This is because, there are a fixed number of trial in the experiment, each trial has the same number of outcomes, i.e. a person either likes bacon cheeseburgers or sausage bacon cheeseburgers and each trial has the same probability of success, i.e. P (S).
The expected value of a Binomial random variable is:
[tex]E(X)=n\times p[/tex]
Compute the expected number of attendees whose favorite type of burger is a sausage bacon cheeseburger as follows:
[tex]E(X)=n\times p[/tex]
[tex]=1400\times 0.543\\=760.2\\\approx 760[/tex]
Thus, the most reasonable estimate for the number of Sunset Park Food Festival attendees whose favorite type of burger is a sausage bacon cheeseburger is 760.

The area of a rectangle with dimensions of 8 cm by 6 cm is removed from the area of a circle with a radius of 5 cm.
Answer: 30.5 cm²
To get the the area of the rectangle all we have to do is:
Rectangle Area = 6 × 8 = 48 cm²
Same thing to the circle, multiply the radius and pi:
Circle Area = 3.14 x 5² = 78.5 cm²
We have to subtract the two areas to find the shaded area.
78.5 - 48 = 30.5 cm²

Answer:D,180
Step-by-step explanation:
Answer:
9 x 20ft = 180
If one of those values 8ft and 20ft is the diagonal then we deduct the square of thise numbers being √400 - √81 = √309 and find √309 square of 17.57ft
17.57 x 9 = 158.13
so √158.12 = 12.57
and √162 = 12.72
But your question was just a case of finding how to do area and for that we use L x W to find area
A = 9 x 20 = 180ft^2

Your soccer club wants to sell frozen yogurt to raise money for new uniforms. The club has the choice of the two different size containers shown. Each container costs the club the same amount. The club plans to charge customers $2.50. Which container should the club buy? Explain.
Answer:
they should buy the smaller one. the yogurt will cost money too. that is why other companys put ice, or empty spaces in cups.
Step-by-step explanation:
The soccer club should choose either Container A or Container B, as both options would generate the same profit of $1.00 per container sold, assuming the cost price is $1.50 and the selling price is $2.50.
To determine which container is more profitable, we need to calculate the profit from each option. For both containers, the selling price is $2.50.
Let's assume the cost of each container is $1.50, which includes the frozen yogurt, packaging, and other associated costs.
Container A Profit:
Selling Price: $2.50
Cost Price: $1.50
Profit per Container: $2.50 - $1.50 = $1.00
Container B Profit:
Selling Price: $2.50
Cost Price: $1.50
Profit per Container: $2.50 - $1.50 = $1.00
As we can see, both Container A and Container B would yield the same profit of $1.00 per container, given the assumed cost price and selling price.

How much energy would a 15,000 g block of ice need to absorb in order to
melt? The heat of fusion of ice is 333 J/g. Enter your answer to the nearest
whole number of kJ.
Answer:
The energy a 15,000 g block of ice will absorb in order to melt is 4995 kJ
Step-by-step explanation:
The question relates to the latent heat of fusion of ice, that is the heat absorbed by the solid ice to convert it to liquid water without changing its temperature.
The formula for the energy required to melt the ice is presented as follows;
Energy required = Mass, m × Latent heat of fusion, [tex]L_f[/tex], of ice
Hence, the mass, m, of the ice = 15,000 g
Latent heat of fusion, [tex]L_f[/tex], of ice = 333 J/g
Therefore;
Energy required = 15,000 g × 333 J/g = 4995000 J
Hence;
The energy a 15,000 g block of ice will absorb in order to melt = 4995000 J
1000 J = 1 kJ
1 J = 1/1000 kJ
Therefore, 4995000 J = (4995000 J)/(1000 J/kJ) = 4995 kJ.
Which gives;
The energy a 15,000 g block of ice will absorb in order to melt = 4995 kJ.
Write an equation of the line that passes through a pair of points: (negative 2, 2), (5, negative 5)
To find the equation of the line through (-2, 2) and (5, -5), calculate the slope which is -1 and then use the slope-intercept form to find the y-intercept, which is 0. The equation of the line is y = -x.
Explanation:To write an equation of the line that passes through the points (-2, 2) and (5, -5), you need to determine the slope and the y-intercept of the line. First, calculate the slope (m) which is the change in y divided by the change in x: m = (y2 - y1) / (x2 - x1).
Using the points (-2, 2) and (5, -5), the slope calculation would be: m = (-5 - 2) / (5 - (-2)) = (-7) / (7) = -1. This indicates that the line has a negative slope.
Next, use the slope-intercept form of a line, which is y = mx + b, where m is the slope and b is the y-intercept. To find b, use one of the given points and the slope you calculated: 2 = (-1)(-2) + b, which simplifies to 2 = 2 + b, and thus b = 0.
The equation of the line is therefore y = -1x + 0, which simplifies to y = -x.

The local cell phone tower service for your provider has the best service when you are 15 miles from the tower, if the school is 12 miles east and 11 miles south then will you receive the most bars?
Answer:
No, since the total distance to the cell tower is 16.28 miles, which is farther away than the distance needed to get the best possible service. You are 1.28 miles too far.
Step-by-step explanation:
you have a triangle with sides 12 miles and 11 miles long, so all you need to do is calculate the hypotenuse:
h² = 12² + 11²
h² = 144 + 121
h² = 265

A basketball has a diameter of 14 inches. If it fits inside a cube-shaped box that has a side length of 13
inches, what is the volume, rounded to the nearest hundredth of a cubic inch, of the space inside the box
that is not taken up by the basketball?
Answer:
The space inside the box = 2197 in³ - 1436.76 in³ is 760.245 in³.
Step-by-step explanation:
Here we have the volume of the cube box given by the following relation;
Volume of cube = Length. L × Breadth, B × Height, h
However, in a cube Length. L = Breadth, B = Height, h
Therefore, volume of cube = L×L×L = 13³ = 2197 in³
Volume of the basketball is given by the volume of a sphere as follows;
Volume = [tex]\frac{4}{3} \pi r^3[/tex]
Where:
r = Radius = Diameter/2 = 14/2 = 7in
∴ Volume of the basketball = [tex]\frac{4}{3} \times \pi \times 7^3 = 1436.76 \ in^3[/tex]
Therefore, the space inside the box that is not taken up by the basketball is found by subtracting the volume of the basketball from the volume of the cube box, thus;
The space inside the box = 2197 in³ - 1436.76 in³ = 760.245 in³.
What should you NOT use a loan to purchase?
A car
A house
Tuition for higher education
Airline tickets to your dream vacation
Answer:
Airline tickets
Step-by-step explanation:
The other three could be considered important. Your dream vacation may seem important to you, but is something you should only do if you can pay for it. Never go in debt for it.
While loans can be beneficial for purchasing items that generate a return or are necessary, such as a house, car, or higher education, it's generally unwise to take out a loan for things like vacations, which do not provide a return on investment.
Explanation:While it can be tempting to use a loan for many things, there are certain items that are typically seen as poor investments. A house, car, and higher education tuition are often considered acceptable things to take out a loan for, as they can provide a return on your investment and can be seen as necessary for longer term wealth-building. On the other hand, an airline ticket for a vacation is generally not a recommended use for a loan.
The primary reason being that it is not an investment that will appreciate in value or generate income. In fact, it's a depreciating asset because once you've taken the vacation, you have nothing to show for your money, except for the experience and memories. Additionally, taking a loan for such purposes might lead to a situation where you may struggle to repay the debt once you are back from vacation, which can lead to cascading debts and bad credit.

The diameter of a tennis ball is 2 cm and the diameter of the softball is 1 cm. About how many times as
great is the surface area of a half of the tennis ball as to the surface area of a half of the softball? If
necessary, round to the nearest whole number.
Step-by-step explanation:
It is given that,
The diameter of a tennis ball is 2 cm and the diameter of the softball is 1 cm. So, radius of tennis ball is 1 cm and radius of softball is 0.5 cm.
Both balls are in the shape of sphere. Half of the balls will becomes hemisphere. The surface area of hemisphere is given by :
[tex]A=2\pi r^2[/tex]
Taking ratio of both balls, i.e.
[tex]\dfrac{A_1}{A_2}=\dfrac{r_1^2}{r_2^2}[/tex]
[tex]\dfrac{A_t}{A_s}=\dfrac{r_t^2}{r_s^2}\\\\\dfrac{A_t}{A_s}=\dfrac{1^2}{(0.5)^2}\\\\\dfrac{A_t}{A_s}=4[/tex]
So, the surface area of a half of the tennis ball is 4 times of he surface area of a half of the softball.
The surface area of half of a tennis ball is 4 times greater than the surface area of half of a softball.
To find how many times greater the surface area of half of a tennis ball to that of half of a softball is, we need to use the formula for the surface area of a sphere: Surface Area = 4πr².
Since we are dealing with half-spheres, we can halve this formula, so the surface area of the half-sphere is 2πr².
First, we calculate the surface area for half of a tennis ball. The radius of the tennis ball is 2 cm / 2 = 1 cm. Thus, the surface area is:
Surface Area of Tennis Ball Half-Sphere = 2π(1)² = 2π cm²
Next, we do the same for the softball. The radius of the softball is 1 cm / 2 = 0.5 cm. Therefore, the surface area of half of the softball is:
Surface Area of Softball Half-Sphere = 2π(0.5)² = 0.5π cm²
To find the ratio of the tennis ball surface area to the softball surface area, we divide the two results:
(2π) / (0.5π) = 4
Thus, the surface area of half of a tennis ball is 4 times greater than that of half of a softball.

A farmer wants to fence a rectangular area for her cows. The area is 200 yards by 423 yards. How many yards of
fencing does she need?
Answer:
1246 yards
Step-by-step explanation:
To find the yard of fencing she needs for he cows, we simply need to find the perimeter of the rectangular area.
The area is 200 yards by 423 yards.
The perimeter is the sum of all the sides of a rectangle and it is given by:
P = 2(L + B)
P = 2(200 + 423) = 2(623)
P = 1246 yards.
She needs 1246 yards of fencing.

Final answer:
The correct width of Tamara's backyard is calculated by dividing the area by the length, resulting in a width of 2/15 miles.
Explanation:
The student's question involves setting up an equation to find the width of a rectangular backyard given its length and area. To find the width, we use the formula for the area of a rectangle, which is Length × Width = Area. Tamara's backyard has a length of 5/2 miles and an area of 3/9 square miles. Setting up the equation correctly, we have:
(5/2 miles) × Width = 3/9 square miles
To find the width, we divide both sides of the equation by the length:
Width = (3/9 square miles) / (5/2 miles)
After simplification, which we can do by multiplying by the reciprocal of 5/2, we get:
Width = (3/9) × (2/5) miles
Width = (3 × 2) / (9 × 5) miles
Width = 6/45 miles
After further simplification:
Width = 2/15 miles
Therefore, the correct width of Tamara's backyard is 2/15 miles.
