Answer:

I think that to go to the temperature you you can draw a straight line then on one side write negative the other side positive that the centre write 0 then locate -14 and 12 so negative 14 will fall on the negative side and 12 will fall on the positive side then count from -14 up to positive 12 and you'll find that it changed by 26°

Step-by-step explanation

The answers in bold is what was required from the question.

the null hypothesis using symbol:-

H₀ : μ = 11.80

the alternative hypothesis using symbol:-

H₁:  μ ≠ 11.80

This is a one tailed test. Given what you know, you will evaluate this hypothesis using a t test statistic.

Alpha level = 0.05

Sample size = n

Degree of freedom = n-1 = 40-1 = 39

To use the t distribution we will have to find the critical value from the t table this value is 1.685

But the question does not have sample mean and sample standard deviation. So I was unable to solve for the standard error

[tex]\frac{5}{2}x-7=\frac{3}{4}x+14[/tex]

[tex]\frac{5x}{2}-7=\frac{3}{4}x+14\\\\\frac{5x}{2}-7=\frac{3x}{4}+14[/tex]

10x−28=3x+56

10x=3x+56+28

10x=3x+84

10x−3x=84

7x=84

[tex]x=\frac{84}{7}[/tex]

x=12

Answer:

  10

Step-by-step explanation:

Corresponding angles of congruent triangles are congruent.

  angle B = angle E

  3v +4 = 8v -6

  10 = 5v

  v = 2

Then the measure of angle B is

  3v +4 = 3(2) +4 = 10 . . . measure of ∠B

Answer:

21 and 1/3

Step-by-step explanation:

2/3 five times would be 4 and then times that by 4 you get 16

1 and 1/3 times 4 would be 5 and 1/3

5 and 1/3 plus 16=21 and 1/3

Answer:

(6,3)

Step-by-step explanation:

If you reflect (-4,3) over the y-axis it is going to become (4,3).

Then, if you move it 2 units to the right, it becomes (6,3)

The coordinates of the point  (-4,3) after reflection and translation will be ( 6, 3 ).

The process of changing the location of the image on the coordinate system will be known as the translation.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

Given that the point  (-4,3) is the image of A after a reflection using the y-axis, then a translation of two units to the right.

Reflection of point ( -4 , 3 ) ⇒ ( 4 , 3 )

A translation of two units to the right ⇒ ( 4 + 2, 3 ) ⇒ ( 6, 3 )

Therefore, the coordinates of the point  (-4,3) after reflection and translation will be ( 6, 3 ).

The value  is [tex]t = 2.51 [/tex]

Step-by-step explanation:

From the question we are told that

   From the question we are told that  

    The first sample mean is  [tex]\= x_1 = 71.1[/tex]

     The first standard deviation is [tex]\sigma _1 = 19.4[/tex]

     The  second sample mean is  [tex]\= x_2 = 63.4[/tex]

     The second sample  deviation is  [tex]\sigma_2 = 10.5[/tex]

     The first sample size is  [tex]n_1 = 55[/tex]

      The second sample size is  [tex]n_2 = 46[/tex]

Generally the test statistics is mathematically represented as

         [tex]t = \frac{\= x_1 - \= x_2 }{ \sqrt{\frac{s_1^2 }{n_1} +\frac{s_2^2 }{n_2} } }[/tex]

=>   [tex]t = \frac{71.1 - 63.4 }{ \sqrt{\frac{19.4^2 }{55}  +\frac{10.5^2 }{46}   } }[/tex]

=>   [tex]t = 2.51 [/tex]

Answer:

a. Numerical (discrete).

b. Categorical.

c. Numerical (continuous).

d. Numerical (continuous).

e. Categorical.

Step-by-step explanation:

In Mathematics, a categorical data can be defined as a statistical data type that is used to group informations having the same attributes or characteristics. Some examples of a categorical data are age, gender, race, religion etc.

A numerical data can be defined as a data set that is expressed in numbers only or a data set consisting of numbers rather than words. A numerical data is also known as a quantitative data.

Basically, numerical data are classified into two (2) main categories and these are;

1. Discrete data: a discrete data is a data set in which the number of possible values are either finite or countable. For instance, the value of a fair die, number of sweets in a jar, number of eggs in a crate etc.

2. Continuous data: a continuous data is a data set having infinitely many possible values and those values cannot be counted, meaning they are uncountable. Any quantity such as height, volume, weight, density, length, pressure, temperature, speed, distance, time are generally a continuous data.

a. Number of students in a class of 35 who turn in a term paper before the due date: this is a numerical data and it is discrete in nature because the number of possible values are finite or countable.

b. Gender of the next baby born at a particular hospital: this is a categorical data because it contains a nominal variable (gender).

c. Amount of fluid (in ounces) dispensed by a machine used to fill bottles with soda pop: this is a numerical data and it is continuous in nature because the number of possible values are infinite or uncountable.  

d. Thickness of the gelatin coating of a vitamin E capsule: this is a numerical data and it is continuous in nature because the number of possible values are infinite or uncountable.

e. Birth order classification (only child, firstborn, middle child, lastborn) of a math major: this is a categorical data because it is used to categorize an information (birth order).

Answer:

b(side length) = 15 centimeters

Step-by-step explanation:

Given an assumed regular rectangular prism which has a height of 18, and volume of 4050 cubic centimeters.

We are also given the formula b = (v/18)^1/2 which is said to find the side length of the rectangular prism. Therefore, it is implied that b must be the side length. Since we know everything except the side length we can substitute the volume since we are already given the height in the formula derived from the problem.

b = (4050/18)^1/2

b = (225)^1/2

b = 15

___________

We should also know that the volume of a rectangular prism is defined as V = l × w × h, with l as the length, w as the width, and h as the height, given that b is the side length which is multiplied by the width and height to get 4050, the base must be a square. Since 4050 = 15 × w × 18

4050 = 270 × w

4050/270 = w

15 = w

w = 15.

A square base is when the length and width are equal. Therefore this value has to be true.

As 15 × 15 × 18 = 4050.
