New heat lamps are reported to have the mean lifespan of 100 hours with a standard deviation of 15 hours. Before replacing their current lamp to the new heat lamps for the university, OSU decided to test whether the mean lifetime is equal to 100 or not by sampling 36 heat lamps. They turned them on and recorded the time, in hours, until each lamp failed. The sample provided a mean lifespan is 105.1 hours.
1) What set of hypotheses are correct for this problem?
SET 1 - H0: µ = 100 hours , Ha: µ < 100 hours
SET 2 - H0: µ = 100 hours , Ha: µ > 100 hours
SET 3 - H0: µ = 100 hours , Ha: µ ≠ 100 hours
A) SET 1.
B) SET 2.
C) SET 3.
2) If we assume the null hypothesis to be true, the average of the distribution of sample means, μ x ¯, from a sample size of 36 is:______.
a) 15.
b) 115.
c) 100.
d) 105.1. .
3) According to the Central Limit Theorem, the standard deviation of the distribution of the sample means is:______.
a) 115.
b) 15.
c) 6.
d) 2.5. .
4) What is the approximate probability of observing a sample mean of 105.1 or more from the distribution of sample means, again assuming that the null hypothesis is true?
a) 0.68.
b) 0.025.
c) 0.975.
d) 0.16.
Answer:
1
The correct option is C
2
The correct option is C
3
The correct option is A
4
The correct option is B
Step-by-step explanation:
From the question we are told that
The population mean is \(\mu = 100\)
The standard deviation is \(\sigma = 15\)
The sample size is \(n = 36\)
The sample mean is \(\= x = 105.1\)
Generally
The null hypothesis is \(H_o: \mu = 100 \ hours\)
The alternative hypothesis is \(H_a : \mu \ne 100\ hours\)
Given that the null hypothesis is true then the distribution of sample means \(\mu_{\= x }\), from a sample size of 36 is mathematically represented as
\(\mu_{\= x } = \mu\)
=> \(\mu_{\= x } = 100\)
According to the Central Limit Theorem the test stated in the question is approximately normally distributed if the sample size is sufficiently large\((n > 30 )\) so given that the sample size is large n = 36
Then the test is normally distributed and hence the standard deviation is 15
Generally the standard error of mean is mathematically represented as
\(\sigma_{\= x } = \frac{ \sigma }{\sqrt{n} }\)
=> \(\sigma_{\= x } = \frac{15}{\sqrt{36} }\)
=> \(\sigma_{\= x } = 2.5\)
Generally the approximate probability of observing a sample mean of 105.1 or more is mathematically represented as
\(P( \= X \ge 105.1 ) =1 - P(\= X < 105.1) = 1- P(\frac{\= X - \mu }{\sigma_{\= x }} <\frac{105.1 - 100}{2.5} )\)
=> \(P( \= X \ge 105.1 ) =1 - P(\= X < 105.1) = 1- P(Z<2.04 )\)
From the z-table (reference calculator dot net )
\(P(Z<2.04 ) = 0.97932\)
So
\(P( \= X \ge 105.1 )= 1 - P(\= X < 105.1) = 1- 0.97932\)
\(P( \= X \ge 105.1 ) =0.02\)

Answer:
tangent: y = 2x -2normal: y = -1/2x +3Step-by-step explanation:
Differentiating implicitly, you have ...
-y²·dx +(4-x)(2y)dy = 3x²·dx
So, the slope is ...
dy/dx = (3x² +y²)/(2y(4 -x))
At (x, y) = (2, 2), the slope of the curve is ...
dy/dx = (3·2² +2²)/(2·2(4 -2)) = 16/8 = 2
In point-slope form, the equation of the tangent line is then ...
y = m(x -h) +k
y = 2(x -2) +2
y = 2x -2 . . . . equation of tangent line
__
The normal to the curve is perpendicular to the tangent at the same point. The slope of the perpendicular line is the negative reciprocal of the tangent's slope, so is -1/2.
y = (-1/2)(x -2) +2
y = -1/2x +3 . . . equation of normal line
Give five elements of the following sets.

B = {x/x is a prime number greater than 20 but less than 50}
C = {even number less than 20}
D = {fraction less than 1}
E = {noun that starts with letter "a"}
Answer:
Find the answer below.
Step-by-step explanation:
1. A = {mountain, valley, plateau, plains and hills}
A landform refers to a geomorphic or natural feature of the Earth's surface, which typically makes its terrain.2. B = {23, 29, 31, 37 and 41}
A prime number can be defined as any number that is greater than one (1) and can only be divided by itself or one (1). In this case, they are greater than 20 but less than 50.3. C = {2, 4, 8, 10 and 12}
An even number can be defined as any number that can be divided by two (2) without any remainder. In this instance, they should be between one (1) and twenty (20).4. D = {2/3, 1/2, 3/4, and 1/5}
A fraction that is less than one (1) refers to a proper fraction. Therefore, proper fractions must have the value of their numerator to be less than the value of their denominator.5. E = {ant, angel, angle, anaconda, and ark}
A noun can be defined as the name of any place, people, animal or things. In this context, the nouns should all start with the letter "a."what is one quality of rotation

there is a zero at x = 1 (option D)
Explanation:
a) The graph shows it is going up (increasing towards both the y axis and x axis).
This graph will give a positive leading coefficient.
As a result, the equation will have a positive leading coefficient not a negative one.
b) zeros of a polynomial are the values of x when the line crossses the x axis.
From our graph, the line doesn't cross the x axis at x = 6.
As a result, there is no zero of -6.
Multiplicity tells us the number of times the number of times a factor occurs.
Since part of the statement is wrong, it makes the whole statement wrong
c) The degree of this graph is odd. Its equation is 3rd degree
d) From the graph, the line crosses the x axis at x = 1 (2nd tick line)
Each tick line represents 0.5
The zero is the value of x when it crosses the x axis
As a result the polynomial has a zero at x = 1
The correct option is there is a zero at x = 1 (option D)

A right triangle with two sides are on the x and y axes with endpoints 0,0 0,y and x,0 the hypotenuse passes through point
The distance from the midpoint of the hypotenuse of any vertex is:
\(\sqrt{(0-a)^2 +(2b - b)^2} \\\) = \(\sqrt{(2a - a)^2 +(0 -b)^2}\)
= \(\sqrt{a-0)^2 + (b -0)^2}\)
Right Angle Triangle:
A right triangle is a triangle with one of its angles 90 degrees. An angle of 90 degrees is called a right angle, so a triangle with a right angle is called a right triangle. In this triangle, we can use the Pythagorean law to easily understand the relationship of the various sides. The side opposite the right angle is the largest side and is called the hypotenuse.
In a right triangle we have:
(Hypotenuse)2 = (Base)2 + (Altitude)2
Mid point Theorem:
The midpoint theorem states that the line segment joining the midpoints of any two sides of a triangle is parallel to the third side and equal to half the length of the third side. This theorem is used in many places in real life. For example, if we don't have a measuring tool, you can use the midpoint theorem to cut a bar in half.
If we have a line segment whose endpoint coordinates are given by
(x₁, y₁) and (x₂, y₂), we can find the coordinates of the midpoint of the line segment using the following formula:
Let (xₙ , yₙ ) Coordinates of the midpoint of the segment. Then
(xₙ, yₙ) = ( (x₁+ x₂/2 , (y₁ + y₂)/2 )
This is known as the midpoint theorem.
According to the Question:
Suppose that we have two points (x₁ ,y₁) and (x₂, y₂). The distance between them is given by:
D = \(\sqrt{(x_2-x_1)^2 + (y_2- y_1)^2 }\)
Hence the distance from the midpoint of the hypotenuse to any vertex is given by:
\(\sqrt{(0-a)^2 +(2b - b)^2} \\\)
= \(\sqrt{(2a - a)^2 +(0 -b)^2}\)
= \(\sqrt{a-0)^2 + (b -0)^2}\)

2x^2 -6x
5x^2 + 11x + 2
2x(5x + 1) / (4x - 1) is the final expression.
Option D is the correct answer.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
(4x³ - 12x²) / (4x² + 7x - 2) / (2x² - 6x) / (5x² + 11x + 2)
= (4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)
Now,
(4x³ - 12x²) = 4x² (x - 3) _____(1)
And,
(5x² + 11x + 2)
Middle term factorizing
= 5x² + (10 + 1)x + 2
= 5x² + 10x + x + 2
= 5x (x + 2) + 1(x + 2)
= (x + 2) (5x + 1) ______(2)
And,
(4x² + 7x - 2)
Middle term factorizing
= 4x² + (8 - 1)x - 2
= 4x² + 8x - x - 2
= 4x(x + 2) - 1(x + 2)
= (4x - 1) (x + 2) ______(3)
And,
(2x² - 6x) = 2x (x - 3) ______(4)
From (1), (2), (3), and (4) we get,
(4x³ - 12x²) x (5x² + 11x + 2) / (4x² + 7x - 2) x (2x² - 6x)
= [ 4x² (x - 3) x (x + 2) (5x + 1) ] / [ (4x - 1) (x + 2) x 2x(x - 3) ]
(x + 2) and (x - 3) gets canceled.
= [4x² (5x + 1)] / [(4x - 1) 2x]
= 2x(5x + 1) / (4x - 1)
Thus,

given that y various with x, find the equation of direct variation when x=11 and y=14
Answer:
The equation of direct variation relates two variables that vary proportionally to each other, and can be written as y = kx, where k is the constant of proportionality. To find k, we can plug in the values of x and y given in the problem and solve for k:
y = kx
14 = k(11)
k = 14/11
Now that we know k, we can write the equation of direct variation as:
y = (14/11)x
Therefore, when x = 11 and y = 14, the equation of direct variation is y = (14/11)(11) = 14.

Slope = ((y2 - y1) / (x2 - x1)) = ((10 - 14) / (-7 - 3)) = (-4 / -10) = 2/5
Midpoint = ((x1 + x2) / 2)), ((y1 + y2) / 2)) = ((-7 + 3) / 2), ((10 + 14) / 2)) = (-2, 12)
Presently, let's calculate the linear equations for each case:
Help Center to Water Slide #1:
The Slope is 0, and the y-coordinate is consistent, so the equation is y = 3.
Toddler area to Concessions:
The Slope is -1/3, and the y-intercept can be calculated utilizing the midpoint facilitates:
-7.5 = (-1/3)(1.5) + b
-7.5 = -0.5 + b
b = -7
Gift Shop to Restrooms:
The Slope is 0, and the y-coordinate is steady, so the equation is y = -9.
