A newsletter publisher believes that 49% of their readers own a personal computer. A testing firm believes this is inaccurate and performs a test to dispute the publisher's claim. After performing a test at the 0.05 level of significance, the testing firm decides to reject the null hypothesis. What is the conclusion regarding the publisher's claim?

Answers

Answer:

The conclusion regarding the publisher's claim is that the 49% of their readers  own a personal computer.

Step-by-step explanation:

The null hypothesis is always opposite of the claim . If the null hypothesis is rejected it means the claim is accepted.

The alternate hypothesis ( claim) is

Ha: u = 0.49

The null hypothesis  is

H0 : u ≠ 0.49

The null hypothesis is rejected. The claim is accepted.

The claim ( alternate hypothesis ) was the newsletter publisher believe which is accepted.

The conclusion is drawn that the newsletter publisher was accurate that 49% of their readers  own a personal computer.

Cody's Seafood House purchases
shrimp for $5.00 per pound. If the
shrimp is marked up 65% how much,
will guests pay for 2 pounds of
shrimp ?

Answers

Answer:

Try this

Step-by-step explanation:

So what you have to do is turn 65% into a decimal. 65% as a decimal is 0.65.

Then what you want to do is divide 5.00 and 0.65 and see what you get.

5×65%=3.25
3.25+5=8.25
8.25×2=16.5

Therefore, your answer is "The guests will pay $16.50 for 2 pounds of shrimp".

Write the equation of the quadratic function with vertex (7,9) in Vertex
Form.

Answers

9514 1404 393

Answer:

  y = (x -7)² +9

Step-by-step explanation:

The vertex form of the quadratic equation is ...

  y = a(x -h)² + k . . . . . . . . vertex (h, k); vertical scale factor 'a'

If we use a vertical scale factor of a=1, then putting the vertex (h, k) = (7, 9) into the vertex form gives ...

  y = (x -7)² +9

Robin hood plans to use a 54 ft ladder to reach the castle window of Maid Marian. Little John, who made the ladder, advised Robin that the angle of elevation of the ladder must be between \displaystyle 55^{of}55 o and \displaystyle 70^{of}70 o for safety. What are the minimum and maximum heights that can safely by reached by the top of the ladder when it is placed against the 50 ft castle wall

Answers

Answer:

The minimum height is: 44.24 ft and the maximum is 50.74ft

Step-by-step explanation:

Given

[tex]L = 54[/tex] --- Length of ladder

[tex]55 \le \theta \le 70[/tex]

Required

The minimum and maximum height

The question is illustrated with the attached image:

The height h is calculated using:

[tex]\sin(\theta) = \frac{h}{54}[/tex] --- sine equation

When [tex]\theta = 55[/tex], we have:

[tex]\sin(55) = \frac{h}{54}[/tex]

Make h the subject

[tex]h = 54 * \sin(55)[/tex]

[tex]h = 54 * 0.8192[/tex]

[tex]h = 44.24ft[/tex]

When [tex]\theta = 70[/tex], we have

This gives:

[tex]\sin(70) = \frac{h}{54}[/tex]

Make h the subject

[tex]h = 54 * \sin(70)[/tex]

[tex]h = 54 * 0.9397[/tex]

[tex]h = 50.74ft[/tex]

The minimum height is: 44.24 ft and the maximum is 50.74ft

Insert one term between -13 and -119 to create an arithmetic sequence of three terms.

Answers

Answer:

-66

Step-by-step explanation:

- 13, ____, -119

first, find the common difference:

-13 - (-119) = 106

next, divide 106 by 2: [tex]\frac{106}{2}[/tex] = 53

so, the common difference is 53.

now, subtract 53 from -13:

-13 - 53 = -66

Answer:

-66

Step-by-step explanation:

the sequence goes -13,-66,-119

just subtract with 53

Answer:

a. True, b. y = (-1/2)x + 8

Step-by-step explanation:

Because the graph is a straight line, that means that the graph is in fact proportional. For the equation, take the form y = mx+b. Plug in the slope, which is -1/2, and the y-intercept, which is 8, which would give you the equation y = (-1/2)x + 8.

Yes just because some are small and some are big doesn't mean that they are different. And the formula for a circles circumference is C=2pi r and 2 and pi are alaway the same the only thing that changes is r.

5. What do you know about the hypotenuse of △ABC? (2 points)




6. In your diagram in question 3, extend the hypotenuse of △ABC so that it creates the hypotenuse of a right triangle inscribed in the larger circle. Add point Y to the larger circle so it is equidistant from X and Z. Then complete isosceles triangle XYZ. (1 point)

Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time. Suppose that six of these individuals are randomly assigned to a particular examiner, and let X be the number among the six who are taking the test for the first time. a. What kind of a distribution does X have (name and values of all parameters)

Answers

Answer:

X has an hypergeometric distribution, with parameters:

Size of the population is N = 18.

Size of the sample is n = 6.

Number of successes n is k = 8.

Step-by-step explanation:

The people are chosen without replacement, which means that the hypergeometric distribution is used.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

[tex]P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}[/tex]

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

Combinations formula:

[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

Eighteen individuals are scheduled to take a driving test at a particular DMV office on a certain day, eight of whom will be taking the test for the first time.

This means that [tex]N = 18, k = 8[/tex]

We consider a success being a person taking the test for the first time, because X is the number among the six who are taking the test for the first time.

Suppose that six of these individuals are randomly assigned to a particular examiner.

This means that [tex]n = 6[/tex]

a. What kind of a distribution does X have (name and values of all parameters)

X has an hypergeometric distribution, with parameters:

Size of the population is N = 18.

Size of the sample is n = 6.

Number of successes n is k = 8.

Find the volume of the figure

Answers

Answer:

66 ft³

Step-by-step explanation:

The figure can be divided into a cuboid and a triangular prism.

Volume of the cuboid = l × w × h

Where l = 6ft, w = 3 ft and h = 2 ft

Volume = 6 × 3 × 2 = 36 ft³

Volume of  the triangular prism = Cross sectional area × Width

Where Cross sectional area = 0.5 × 10 ft × 2 ft and Width  = 3 ft

Volume = 10 × 3 = 30 ft³

Total volume = Volume of the cuboid + Volume of the triangular prism

∴ Volume of the figure = 66 ft³
