A restaurantis planning to make changes to its menu. In order to decide which potential menu items are most popular with the city's population, the owners will conduct a survey. Which survey methods would produce a representative sample of the city's population
Answer:
Simple random sampling survey method
Step-by-step explanation:
A simple random sampling is an unbiased survey technique Hence it will represent all the parts of the city's population.
In statistics, a simple random sample is a subset of individuals (a sample) chosen from a larger set (a population). Each individual is chosen randomly and entirely by chance, such that each individual has the same probability of being chosen at any stage during the sampling process

Your goal is to design a new shape for a cereal container that will hold the same volume of cereal as a standard ceareal box and costs as little as possible to make. Assume that cardboard costs $0.05 per square inch. How cheaply can you package cereal?
These figures are available.
* triangular prism
* rectangular prism
* cube
* pyramid
* cone
* cylinder
* sphere
You need to keep the volume the same as the original, the surface area has to be less, and the price has to be the cheapest. The original volume was 192in^3. The surface area was 272in^2.
Answer:
$14.50
Step-by-step explanation:
To calculate the cost for manufacturing a standard cereal box, we must take in account its surface area. The volume will be used to estimate the amount of cereal, the box can contain. The box is a cuboid as standard cereal boxes are cuboid.
So, we will consider the surface area. Given are:
Length- 8 inches
Width- 3 inches
Height- 11 inches
We will find the surface area as : 2lw + 2wh +2lh
= (2x8x3) + (2x3x11) + (2x8x11)
= 48 + 66 + 176 = 290 square inches
Given is - the cost of manufacturing the box is $0.05 per square inch.
So, cost of manufacturing the box with 290 square inches area =
0.05 x 290 = $14.50
The answer is $14.50

What is the measure of \angle B∠Bangle, B?
^\circ
∘
degrees
Answer:Angle B is 44 Degrees
Step-by-step explanation: Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees
The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees
The angles of triangle ABC must add up to 180 degrees
m∠A+m∠B+m∠C=180
46+m∠B+90=180
m∠B+136=180
m∠B=44
The measure of Angle B in the given diagram is 44 Degrees
Angle C intersects the circle at the endpoints of a diameter, it intercepts an arc of 180 degrees
The measure of an inscribed angle is half the measure of its intercepted arc, so we know that the measure of angle C is 90 degrees
What is the sum of the angles in a triangle?The angles of triangle ABC must add up to 180 degrees.
The total sum of the angle in triangles is180 degrees.
m∠A+m∠B+m∠C=180
46+m∠B+90=180
m∠B+136=180
m∠B=44
Therefore, The measure of Angle B in the given diagram is 44 Degrees.

Find the area of the Combined Rectangles.
Answer:
128
Step-by-step explanation:
First, I cut this rectangle in half vertically, right through the middle.
To find the area of an rectangle, multiply length by the height
Left rectangle area : 8*10 = 80 ( 8 is the height and 10 is the length)
Right rectangle area: 8*6 = 48 (8 is the length and 6 is the height)
Add the lengths together : 80+48= 128
The area of this rectangle is 128

Two parallelograms are similar. The base of the first is 12cm, and its height is 8 cm. Find the base of the second parallelogram if its height is 34 cm.
Answer:
The base of the second parallelogram is 51cm.
Step-by-step explanation:
If the parallelograms are similar, it means by applying the same scale factor to all the sides in one gives you the other. The question tells us the height of the first shape is 8cm and the height of the second shape is 34cm. That means the scale factor is:
[tex]\frac{34}{8}=4.25[/tex]
Apply this same scale factor to the base of the first shape to find the base of the second:

Marcus builds kites for a 14 day summer kite festival he plans to give away about the same number of kites each day he gives away 492 kites the first two days did Marcus stick to his plan?
Answer:
He did not stick to plan; he does not have enough kites.
Step-by-step explanation:
A key information is missing from the question, the number of kites that Marcus made.
After a quick web search, I have found that, in this problem, Marcus has built 2,744 kites in total.
It is know that he gave away 492 kites in the first two days, in a 14 day festival, there are 7 two-day periods. The number of kites required for Marcus to keep that same rate throughout the whole festival is:
[tex]n=\frac{14}{2}=7 \\K=7*492\\K=3,444\ kites[/tex]
Therefore, Marcus did not stick to his plan since he would have needed 3,444 kites to give kites away at the same rate as he did for the first couple days. This could also be interpreted as Marcus giving away too many kites in the first couple days.
Two ships leave the same port. Ship A travels at a constant speed of 30 km/h. Ship B travels at a constant speed of 37 km/h. The angle between their paths 62 degrees. How far apart are the two ships from eachother three hours later?
Answer:
The distance between them is 105.07 km
Step-by-step explanation:
First we need to find the distance travelled by each ship.
To find this distance, we should use the formula:
distance = speed * time
For ship A, we have:
distance1 = 30 * 3 = 90 km
For ship B, we have:
distance2 = 37 * 3 = 111 km
Now, to find the distance between the ships, we can use the law of cosines, where a, b and c are the respectively the distance travelled by ship A, the distance travelled by ship B and the distance between them:
c^2 = a^2 + b^2 - 2*a*b*cos(62)
c^2 = 90^2 + 111^2 - 2*90*111*0.4695
c^2 = 11040.39
c = 105.07 km
The distance between them is 105.07 km

If necessary, round to the nearest hundredth.
Answer:
(8.47,0) (-0.47,0)
Step-by-step explanation:
y = a(x - h)² + k
y = a(x - 4)² - 20
-4 = a(0 - 4)² - 20
16 = 16a
a = 1
y = (x - 4)² - 20
x-intercepts: y = 0
(x - 4)² = 20
x - 4 = +/- 4.47..
x = 4.47+4, -4.47+4
x = 8.47, -0.47
Given that the perimeter of the square below is 40, solve for x. Round your answer to the nearest whole number.

Step-by-step explanation:
Professor Trey Angle writes the equation y=10000(0.75)x on the chalkboard to introduce exponential decay to their students. They explain how when x = 0, y = 10000 and when x = 1, y = 7500. Finish his next statement: "As one gets larger, the other gets smaller. So If x = 3, then y = , which is under half the original value.
Answer:
"As one gets larger, the other gets smaller. So if x = 3, then y = 4218.8, which is under half the original value."
Step-by-step explanation:
In order to complete the sentence we must find the value of "y" when x = 3. We have:
y = 10000*(0.75)^3
y = 4218.8
The sentence then is:
"As one gets larger, the other gets smaller. So if x = 3, then y = 4218.8, which is under half the original value."
