For the following indicate whether a confidence interval for a proportion or mean should be constructed to estimate the variable of interest.
A researcher with a golf association obtained a random sample of 25 rounds of golf on a Saturday morning and recorded the time it took to complete the round. The goal of the research was to estimate the amount of time it typically takes to complete a round of golf on Saturday morning.
The confidence interval for a population____should be constructed because the variable of interest is____which is a____variable.

Answers

Answer: mean; time to complete round; quantitative

Step-by-step explanation:

Based on the information given in the question, the time to complete the round will be the variable of interest.

The confidence interval for a population (mean) should be constructed because the variable of interest is (time to complete round) which is a (quantitative) variable.


A bag contains 5 red marbles, 6 blue marbles and 9 yellow marbles.
What is the probability of picking out a red marble, putting in back in the bag, and then picking out a yellow marble?
What is the probability of picking out a blue marble, putting it in your pocket, and picking out another blue marble?

Answers

Answer:

Step-by-step explanation:

The total number of marbles is 20

Question A

P(Red) = 4/20 = 1/5

P(yellow) = 9/20

P(Red then Yellow) = 1/5 * 9/20 = 9 / 100

Question B

P(B) = 6/20

P(B again) = 5/19 because you  have 1 less total plus 1 less blue.

P(B and B) = 6/20 * 5/19

P(B and B) = 30/ 380 = 3/38

Answers

Answer:

A

Step-by-step explanation:

The product of  the expression [tex]\frac{x^2 - 16}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]  is [tex]\frac{x(x- 1)(x - 4)}{x(x + 4)}[/tex]

What is an expression?

An expression is an algebraic term used for a mathematical statement that include variables and mathematical operations

Below is how to calculate the product

The product expression is given as:

[tex]\frac{x^2 - 16}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]

Express x^2 - 16 as a difference of two squares

[tex]\frac{(x - 4)(x + 4)}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]

Divide the expression

[tex]\frac{x - 4}{2} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]

Factorize the other fraction

[tex]\frac{x - 4}{2} * \frac{x(x^2 - 2x + 1)}{(x -1)(x + 4)}[/tex]

Further factorize

[tex]\frac{x - 4}{2} * \frac{x(x- 1)(x - 1)}{(x -1)(x + 4)}[/tex]

Divide

[tex]\frac{x - 4}{2} * \frac{x(x- 1)}{x + 4}[/tex]

Multiply the fractions

[tex]\frac{x(x- 1)(x - 4)}{x(x + 4)}[/tex]

Hence, the product of  [tex]\frac{x^2 - 16}{2x + 8} * \frac{x^3 - 2x^2 + x}{x^2 + 3x - 4}[/tex]  is [tex]\frac{x(x- 1)(x - 4)}{x(x + 4)}[/tex]

A triangle has sides of lengths 24, 143, and 145. Is it a right triangle? Explain.

Answers

Answer:

Yes, the given triangle is right angled

Step-by-step explanation:

To confirm if the given triangle is right angled, we have to apply pythagoras theorem. It states, if a triangle is right angled then

Hypotenuse² = Base² + Perpendicular²

We know that the longest side is hypotenuse.

ie; (145)² = (143)² + (24)²

(145)² = 20449 + 576

21025 = 21025

As LHS = RHS, it is clear that the given triangle with sides 24, 143 and 145 units is right angled

Assuming the population is normally distributed, find the probability P(x>4.5) given the mean is 6 and the standard deviation is 0.7

Answers

Answer:

[tex]P(x > 4.5)= 0.983943[/tex]

Step-by-step explanation:

Given

[tex]\mu = 6[/tex]

[tex]\sigma = 0.7[/tex]

Required

[tex]P(x > 4.5)[/tex]

Start by calculating the z score

[tex]z = \frac{x - \mu}{\sigma}[/tex]

So:

[tex]z = \frac{4.5 - 6}{0.7}[/tex]

[tex]z = \frac{-1.5}{0.7}[/tex]

[tex]z = -2.143[/tex]

So, we have:

[tex]P(x > 4.5)= 1 - P(x < 4.5)[/tex]

This gives:

[tex]P(x > 4.5)= 1 - P(x < z)[/tex]

[tex]P(x > 4.5)= 1 - P(x < -2.143)[/tex]

Using the z score probability table, we have:

[tex]P(x > 4.5)= 1 - 0.016057[/tex]

[tex]P(x > 4.5)= 0.983943[/tex]

Answers

Answer:

[tex]V=7.45\times 10^{15}\ mm^3[/tex]

Step-by-step explanation:

The radius of each lollipop is 121212 mm

We need to find the volume of each lollipop. The volume of a sphere is given by :

[tex]V=\dfrac{4}{3}\pi r^3[/tex]

Put all the values,

[tex]V=\dfrac{4}{3}\times 3.14\times (121212 )^3\\\\V=7.45\times 10^{15}\ mm^3[/tex]

So, the volume of each lollipop is equal to [tex]7.45\times 10^{15}\ mm^3[/tex].

Which sequence of transformations would create an image that is incongruent to the original pre-image? O A translation 4 units to the left followed by a dilation by 2 O A rotation of 90- followed by a translation of 2 units to the right O A reflection across the y-axis followed by a rotation of 180- O A rotation of 270 followed by a reflection across the x-axis.​

Answers

Answer: Choice A

A translation 4 units to the left followed by a dilation by 2

=============================================================

Explanation:

The following transformations will make the pre-image and image congruent to one another:

ReflectionRotationTranslation

If you apply any of those transformations mentioned above, then the image is an identical copy of the pre-image. Nothing about the figure has changed other than it has been shifted, rotated, or reflected in some way. The figure retains its original size and shape. These transformations are called isometries.

A dilation on the other hand does not preserve the size. "Dilation by 2" means the scale factor is 2, so the image will be twice as large compared to the pre-image, in terms of linear dimension. This means there is no way the image is congruent to the pre-image if a dilation has occurred.

Based on all this, choice A is the answer. Choices B, C, and D only involve the three isometries mentioned earlier and no dilation at all, so they can be ruled out.

Marsha wants to determine the vertex of the quadratic function f(x) = x2 – x + 2. What is the function’s vertex?

(one-half, seven-quarters)
(one-half, three-halves)
(1, 1)
(1, 3)

Answers

Answer:

[tex]Vertex = (\frac{1}{2},\frac{7}{4})[/tex]

Step-by-step explanation:

Given

[tex]f(x) = x^2 - x +2[/tex]

Required

The vertex

We have:

[tex]f(x) = x^2 - x +2[/tex]

First, we express the equation as:

[tex]f(x) = a(x - h)^2 +k[/tex]

Where

[tex]Vertex = (h,k)[/tex]

So, we have:

[tex]f(x) = x^2 - x +2[/tex]

--------------------------------------------

Take the coefficient of x: -1

Divide by 2: (-1/2)

Square: (-1/2)^2

Add and subtract this to the equation

--------------------------------------------

[tex]f(x) = x^2 - x +2[/tex]

[tex]f(x) = x^2 - x + (-\frac{1}{2})^2+2 -(-\frac{1}{2})^2[/tex]

[tex]f(x) = x^2 - x + \frac{1}{4}+2 -\frac{1}{4}[/tex]

Expand

[tex]f(x) = x^2 - \frac{1}{2}x- \frac{1}{2}x + \frac{1}{4}+2 -\frac{1}{4}[/tex]

Factorize

[tex]f(x) = x(x - \frac{1}{2})- \frac{1}{2}(x - \frac{1}{2})+2 -\frac{1}{4}[/tex]

Factor out x - 1/2

[tex]f(x) = (x - \frac{1}{2})(x - \frac{1}{2})+2 -\frac{1}{4}[/tex]

[tex]f(x) = (x - \frac{1}{2})^2+2 -\frac{1}{4}[/tex]

[tex]f(x) = (x - \frac{1}{2})^2+ \frac{8 -1 }{4}[/tex]

[tex]f(x) = (x - \frac{1}{2})^2+ \frac{7}{4}[/tex]

Compare to: [tex]f(x) = a(x - h)^2 +k[/tex]

[tex]h = \frac{1}{2}[/tex]

[tex]k = \frac{7}{4}[/tex]

Hence:

[tex]Vertex = (\frac{1}{2},\frac{7}{4})[/tex]

Labelled points are [tex] (21,\: 17.5)=(x_1,\:y_1) \: \&\:(43,\: 27.75)=(x_2,\:y_2) [/tex]

Slope of line (m) [tex] =\frac{27.75-17.5}{43-21} =\frac{10.25}{22} =\frac{41}{88} [/tex]

Equation of line in point - slope form is given as:

[tex] y-y_1 = m(x-x_1) [/tex]

[tex] \therefore y-17.5= \frac{41}{88} (x-21) [/tex]

[tex] \therefore y= \frac{41}{88} x-\frac{861}{88}+17.5[/tex]

[tex] \therefore y= \frac{41}{88} x+17.5-\frac{861}{88}[/tex]

[tex] \therefore y= \frac{41}{88} x+\frac{1,540-861}{88}[/tex]

[tex] \therefore y= \frac{41}{88} x+\frac{679}{88}[/tex]

[tex] \therefore y=0.465909091x+7.71590909[/tex]

[tex] \therefore y=0.46591x+7.71591[/tex]
