Answers

This question is incomplete, the complete question is;

In order to determine an interval for the mean of a population with unknown standard deviation, a sample of 58 items is selected. The mean of the sample is determined to be 36. The associated number of degrees of freedom for reading the t value is :

a. 35.

b. 57.

c. 36.

d. 58.

Answer: Option b. 57 is the correct answer.

Step-by-step explanation:

Given that;

sample size n = 58

sample mean x" = 36

degrees of freedom for reading the t value is = ?

we know that;

Degree of freedom df = n - 1

where n is the sample size

so we substitute

Degree of freedom df = 58 - 1

Degree of freedom df = 57

Therefore Option b. 57 is the correct answer.

Movie a costs 4 dollars
Movie b costs 5 dollars
Movie theater got 200 dollars and sold 47 tickets
How many tickets did movie a sell

Answers

Answer:

ticket for movie A = 35
ticket for movie B = 12

Step-by-step explanation:

Let A= is ticket  for movie A
Let A= is ticket  for movie B

We have A + B  = 47 (1)
4A + 5B = 200  (2)

From (1) multiply 5 in both side 5A + 5B = 47(5)= 235
                                                     4A + 5B =           200

So A = 35
   B= 47-35 = 12

The area of the rectangle will be:

[tex]A=18x^6+48x^5+6x^4[/tex]

Step-by-step explanation:

Given

height or length = l = 6x³width = w = 3x³+8x²+x

We know that Area of the rectangle

A=wl

  = (3x³+8x²+x) × (6x³)

  [tex]=\left(6x^3\right)\times \:3x^3+\left(6x^3\right)\times \:8x^2+\left(6x^3\right)x[/tex]

  [tex]=3x^3\left(6x^3\right)+8x^2\left(6x^3\right)+x\left(6x^3\right)[/tex]

  [tex]=18x^6+48x^5+6x^4[/tex]

Thus, the area of the rectangle will be:

Answer:

D. 24 degree

Step-by-step explanation:

Sides of the triangle are

a = 330 ft

b = 180 ft

c = 420 ft

From cosine rule we have

[tex]\angle A=\cos^{-1}(\dfrac{b^2+c^2-a^2}{2bc})\\ =\cos^{-1}(\dfrac{180^2+420^2-330^2}{2\times180\times 420})\\ =48.65^{\circ}[/tex]

[tex]\angle B=\cos^{-1}(\dfrac{a^2+c^2-b^2}{2ac})\\ =\cos^{-1}(\dfrac{330^2+420^2-180^2}{2\times 330\times 420})\\ =24.17^{\circ}[/tex]

[tex]\angle C=\cos^{-1}(\dfrac{a^2+b^2-c^2}{2ab})\\ =\cos^{-1}(\dfrac{330^2+180^2-420^2}{2\times 330\times 180})\\ =107.19^{\circ}[/tex]

The smallest angle in the triangle is [tex]\angle B=24.17^{\circ}[/tex].

On the coordinate plane, the segment from X(–
2,2) to Y(8,2) forms one side of △XYZ. The triangle has an area of 20 square units. Select all of the points where Z could be
0,6; 8,6; 4,2; 7,-2

Answers

The coordinates of Z will be  Z(8,6) and Z(4,2)

The formula for the area of triangle is given as :

               A = 1/2 * b * h

where , b = base

            h = height

We have been a ΔXYZ with coordinates of

    X(-2,2) and Y(8,2)

Also the given area is 20 sq. units

We need to find the coordinates of Z from the given question.

First we will find the length of XY which is

XY = [tex]\sqrt{(x_{2} - x_{1})^{2} + (y_{2}- y_{1}) ^{2} } \\[/tex]

     = √(8+2)² + (2-2)²

     = √100

     = 10 units

Let z= (0,6)

distance of YZ = √(0-8)² + (6-2)²

                        = √64+ 16

                        = √80

Area = 1/2 * 10* 4√5 = 20√5 ≠ 20

Let Z = (8,6)

distance of YZ = √(8-8)² + (6-2)²

                        = √16

                        = 4

Area = 1/2 * 10* 4 = 20

let Z = (4,2)

distance of YZ = √(4-8)² + (2-2)²

                        = √16

                        = 4

Area = 1/2 * 10* 4= 20

Let Z = (7,-2)

distance of YZ = √(7-8)² + (-2-2)²

                        = √1 + 16

                        = √17

Area = 1/2 * 10* √17 = 5√17 ≠ 20

Hence the coordinates of Z will be Z(8,6) and Z(4,2) as putting these value we get area equal to 20 square units.

A vacation home in Orlando, Florida, rents for $130 per day. The function (x) = 130x gives the cost of renting the
home for x days. What is the reasonable range of the function in this context?

Answers

The reasonable range of the given function is given by {130, 260, 390, 520, .......}.

What is a range?

A range can be defined as the set of all real numbers that connects with the elements of a domain. This ultimately implies that, a range simply refers to the set of all possible output numerical values, which are shown on the y-axis of a graph.

How to determine the reasonable range of the given function?

In order to determine the reasonable range of the given function, we would create an input and output table to model the relationship between the range and domain as follows:

x         130x         y___

1          130(1)       130

2         130(2)      260

3         130(3)      390

4         130(4)      520

Therefore, the reasonable range of the given function is given by {130, 260, 390, 520, .......}.
