1. If, based on a sample size of 850, a political candidate finds that 458 people would vote for him in a two-person race, what is the 95% confidence interval for his expected proportion of the vote
Answers
Answer:
The 95% confidence interval is
[tex]0.5055< p <0.5725[/tex]
Step-by-step explanation:
From the question we are told that
The sample size is n = 850
The number of can of people that will vote in a two people race is k = 458
Generally the sample proportion is mathematically represented as
[tex]\^ p = \frac{k}{n}[/tex]
=> [tex]\^ p = \frac{458}{850}[/tex]
=> [tex]\^ p = 0.539[/tex]
From the question we are told the confidence level is 95% , hence the level of significance is
[tex]\alpha = (100 - 95 ) \%[/tex]
=> [tex]\alpha = 0.05[/tex]
Generally from the normal distribution table the critical value of is
[tex]Z_{\frac{\alpha }{2} } = 1.96[/tex]
Generally the margin of error is mathematically represented as
[tex]E = Z_{\frac{\alpha }{2} } * \sqrt{\frac{\^ p(1- \^ p)}{n} } [/tex]
=> [tex]E = 1.96 * \sqrt{\frac{0.539(1- 0.539)}{850} } [/tex]
=> [tex] E = 0.0335[/tex]
Generally 95% confidence interval is mathematically represented as
[tex]\r p -E < p < \r p +E[/tex]
=> [tex] 0.539 - 0.0335< p < 0.539 + 0.0335[/tex]
=> [tex]0.5055< p <0.5725[/tex]

Which statement best describes the formation of metamorphic rocks?
A. Magma cools and crystallizes slowly beneath Earth’s surface.
B. Liquid lava erupts from a volcano and cools quickly at Earth’s surface.
C. Sand and gravel are deposited at the mouth of a river and, over time, form layers that solidify into rock.
D. Ancient sandstone beaches become buried deep beneath Earth’s surface, where they are exposed to extreme heat and pressure.
Answers
Answer:
D
Step-by-step explanation:
Metamorphic rock is formed when rocks or minerals are subjected to high heat and high pressure, or a combination of these two factors. Answer D is the only answer that explicitly describes a rock or mineral being subject to these two things, so therefore D is the best answer.

Thunder is the sound caused by lightning. You hear thunder 5 seconds after a lightning strike. The speed of sound is about 1225 kilometers per hour. About how many miles away was the lightning?
Answers
Answer:
it is 1.05
Step-by-step explanation:
The lightning was 1.7 kilometer away.
What is speed?In unit time, the distance covered by any object is called speed.
In mathematical term, Speed is express as S=D/T,
where S=speed, D=distance, T= time.
Given that,
The speed of sound = 1225 kilometers per hour
The speed of sound = 340.277 meter/second
Also, the time after thunder heard = 5 seconds
To find distance, use formula distance = speed × time,
Distance = 340.277 × 5
= 1701.3 meter
= 1.7 kilometer
The lightning was 1.7 kilometer away.

g Suppose 40% of the students in a university are baseball players. If a sample of 781 students is selected, what is the probability that the sample proportion of baseball players will be greater than 43%
Answers
Answer: 0.1271
Step-by-step explanation:
Let p= probability of the students in a university are baseball players.
Given: p= 0.40 , sample size : n= 781
The probability that the sample proportion of baseball players will be greater than 43% will be:
[tex]P(p>0.43)=P(\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}>\dfrac{0.43-0.41}{\sqrt{\dfrac{0.41(1-0.41)}{781}}}\\\\=P(Z>1.14)\ \ \ [Z=\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}]\\\\=1-P(Z<1.14)\\\\=1- 0.8729=0.1271[/tex]
Hence, the probability that the sample proportion of baseball players will be greater than 43% = 0.1271

A carpenter is building a rectangular room with a fixed perimeter of 180 ft. What are the dimensions of the largest room that can be built? What is its area?
Answers
Answer:
Answer: 45ft x 45ft
Step-by-step explanation:
we know that
Perimeter = 2(Length) + 2(Width)
180 = 2L + 2W
90 = L + W
90 - L = W
Area = Length *Width
= L(90 - L) → = 180L - L²
There are 2 different methods for solving (depending on which math course you are taking).
Calculus: find the derivative, set it equal to zero, and solve for L.
= 90L - L² → 0 = 90 - 2L → 2L = 90 → L = 45
Algebra: find the vertex.
= - L² + 90L → L = -b/2a → L = -90/2(-1) → L = 45
insert L it into the Perimeter equation to solve for W:
90 - L = W → 90 - 45 = W → W = 45
Answer: 45ft x 45ft

Which graph shows an odd function?
Answers
Answer: The correct answer is c
Step-by-step explanation:
Graph C depicts an odd function.
We have the four graphs as shown in the figure.
We have to determine which graph depicts an odd function.
What is an Odd function?Assume a function f(x), if : [tex]f(-x) = -f(x)[/tex] i.e., absolute value remains the same if the sign of the independent variable is reversed.
Remember - A function is called even if its graph is symmetrical about the y - axis, odd if its graph is symmetrical about the origin.
It can be seen that - Graph A, Graph B, Graph D are not symmetrical about the origin. Only Graph C - Sine wave is symmetrical about Origin.
Hence, Option C is the graph that depicts the odd function.

The proportion of paintings that were created using the color ultramarine blue was 0.17, with a margin of error of 0.02. Construct a confidence interval for the proportion of oil paintings that contained ultramarine blue.
Answers
Answer:
The confidence interval is [tex]0.15 < p < 0.19[/tex]
Step-by-step explanation:
From the question we are told that
The sample proportion is [tex]\^ p = 0.17[/tex]
The margin of error is [tex]E = 0.02[/tex]
Generally the confidence interval for the proportion of oil paintings that contained ultramarine blue is mathematically represented as
