In a recent poll, 510 people were asked if they liked dogs, and 62% said they did. Find the Margin of Error for this poll, at the 95% confidence level. Give your answer to four decimal places if possible.
Answer:
0.0421
Step-by-step explanation:
Given that
There are 510 people who asked they liked dogs
62% said that yes
We need to find out the margin of the error
So,
standard error is
= sqrt(0.62 × 0.38 ÷ 510)
= 0.0215
now the margin of error is
= 0.0215 × 1.96 z score
= 0.0421
The ratio of Luis´s salary and Andres´s salary is 5 to 3. In July by mistake, Andres received $720 more, which received the same amount from Luis. How much is Luis´s salary?
Answer:
Luis Salary is 1800 dollars
Step-by-step explanation:
Ration of Luis´s salary and Andres´s salary is 5:3
[tex]\frac{L}{A} = \frac{5}{3}\\3L -5A = 0[/tex] -- Eq (1)
Let Luis salary be X
Then Andrews salary in July would be A + 720 while Luis salary in July is L
L = A + 720 ---E q (2)
Substituting the values in above equation 1, we get -
[tex]3 ( A +720 ) -5A = 0\\2 A = 720 *3\\A = 1080[/tex]
Luis Salary is
[tex]A + 720 = 1800[/tex]

A standard die is rolled three times. What is the probability of rolling a number less than 5 on all three rolls?
Answer:
5/6
Step-by-step explanation:
This is because when you roll three times, there are 18 possible numbers (six numbers three times). If you want to get less than five each time, that is 5 number x 3 rolls = 15 numbers.
So...You get 15/18 which simplifies to 5/6
Evaluate the expression if a = 3, b = 5, and c = 6.

Let X be a binomial random variable with parameters (n, p). Find the approximate value of P(|X| > a) when n is sufficiently large using the central limit theorem, where a is a positive number. g
Answer:
Approximate value of P(|X| > a) is attached below
Ф ( 0 ) is the CDF of standard Normal variate
Step-by-step explanation:
x ~ Bin ( n, p )
E ( x ) = np , Var ( x ) = np ( 1 - p )
∴ Z = Iin ( x - E(x) ) / √Var x ) ~ N ( 0, 1 ) ( this is the standard normal Variate)
n-1∞
Find the approximate value of P(|X| > a)
Ф ( 0 ) is the CDF of standard Normal variate
attached below is the remaining part of the solution
According to these measures, is it possible that the heaviest piece of fruit in the two samples was an orange? Explain why or why not.
Answer:
Yes,
Step-by-step explanation:
The measures given which are median and interquartile range have no effect on what the maximum value of a certain distribution will be.
In essence, the information given about the samples of fruits and apples do not point to which fruit sample should possess the sample with maximum weight as the information only gives a general description of each distribution. This means that either samples of orange or apple could have the heaviest piece of fruit.
Decide which ONE of the following statements is FALSE.
A) A line contains at least two points
B) Three non-colinear points determine a plane
C) Through any two distinct points there exists exactly one line
D) Any three points lie on a distinct line
True or False.
A is true, a line has two points which are the two ends.
Answer: Choice D
Any three points lie on a distinct line
=============================================================
Explanation:
Let's go through each statement to see which are true, and which are false.
A) True. A line is uniquely defined by two points. In other words, you need 2 points to form a line.B) True. A plane is a flat surface, such as a table top or a piece of paper. The paper is not allowed to bend or curve. The three points cannot all fall on the same line, hence the "non-colinear" condition put in there. If the 3 points were colinear, then infinitely many planes would go through those points. So we make them non-colinear so a unique single plane can be defined. C) True. See choice A above.D) False. While two points form a single line, that third point may or may not be on that line. If the three points form a single line, then we consider the points colinear. If the points don't all fall on the same line, then we say they are non-colinear. For non-colinear points, a triangle forms. If choice D said "any three colinear points lie on a distinct line", then that statement would be true.Side note: The spelling of "colinear" is sometimes "collinear" with two "L"s, instead of one. I'm not 100% sure which spelling is more acceptable. I've found sources that have used both.

The Toblerone company packages chocolate candy in a container that is a triangular prism. The base is an
equilateral triangle and each side of the triangle is 60 mm. The height of the triangular prism is 405 mm.
1) What is the total surface area of this triangular prism? Show all work and give answers to 2 decimal
places
2) What is the volume of this triangular prism? Show all work and give answers to 2 decimal places
3) If the chocolate inside the package is 335954.96 mm3,how much empty volume/space is inside the
container? Show all work and give answers to 2 decimal places
Answer:
76017.69 mm²
631000 mm³
295045.04 mm³
Step-by-step explanation:
Surface area = bh + 2ls + lb
Since the sides of the triangular prism are equal (equilateral triangle) = 60 mm each
Height = 405 mm
The surface area of triangular = 76017.69 mm
The volume of triangular prism :
1/2 * base * height * length
Volume = 631000 mm³
If amount of chocolate inside = 335954.96 mm3
Empty space =
Volume of triangular prism - amount of chocolate inside
631000 - 335954.96
= 295045.04 mm³

In solving the following problem for x, how do we get the bases to be the same? 2^x-4= 4
Answer:
2^x-4=4
add 4 to both sides
2^x=8
8 is equal to 2*2*2 or 2^3
2^x=2^3
The bases are now both 2 and you can find x.

Answer:
6n - 5 = c, 6n - 5 + n, 7n - 5
Step-by-step explanation:
Pretty much whatever Nina has, Clayton has 6 times that and minus 5. n = Nina, c = Clayton. 6n - 5 + n should also work if they are asking to add both, which can be simplified to 7n - 5.
Hopefully, this helps since the question is kind of worded to confuse, but the answer I gave should be good.
