Answer:

statistical hypothesis.

Step-by-step explanation:

A statistical hypothesis has the central objective of assisting in a decision-making process about one or more populations in relation to the sample data, allowing the observance of whether the information found in the samples will support the statistical hypothesis.

It is necessary to know concepts of mathematical probability to perform the tests, the most used models for this purpose are the fisher method, by Neyman-Pearson and Bayes.

The variables used in a statistical hypothesis are: the Null Hypothesis, the one that is assumed to be the true one, the Alternative Hypothesis, the one that is used when there is no statistic to analyze the hypothesis given as true, the Type I Error, related to the probability of rejection of the null hypothesis, and the Type II Error, which is the probability of rejection of the alternative hypothesis if it is true.

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

[tex]x=8,\:y=5[/tex]

Step-by-step explanation:

Given the system of linear equations

[tex]7x-y=51[/tex]

[tex]x+3y=23[/tex]

solving by the elimination method

[tex]\begin{bmatrix}7x-y=51\\ x+3y=23\end{bmatrix}[/tex]

[tex]\mathrm{Multiply\:}x+3y=23\mathrm{\:by\:}7\:\mathrm{:}\:\quad \:7x+21y=161[/tex]

[tex]\begin{bmatrix}7x-y=51\\ 7x+21y=161\end{bmatrix}[/tex]

[tex]7x+21y=161[/tex]

[tex]-[/tex]

[tex]\underline{7x-y=51}[/tex]

[tex]22y=110[/tex]

so

[tex]\begin{bmatrix}7x-y=51\\ 22y=110\end{bmatrix}[/tex]

now solving for y

[tex]22y=110[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}22[/tex]

[tex]\frac{22y}{22}=\frac{110}{22}[/tex]

[tex]y=5[/tex]

[tex]\mathrm{For\:}7x-y=51\mathrm{\:plug\:in\:}y=5[/tex]

[tex]7x-y=51[/tex]

[tex]7x-5=5[/tex]

[tex]7x=56[/tex]

[tex]\mathrm{Divide\:both\:sides\:by\:}7[/tex]

[tex]\frac{7x}{7}=\frac{56}{7}[/tex]

[tex]x=8[/tex]

[tex]\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}[/tex]

Answer:

3/8

Step-by-step explanation:

1/4 = 2/8

1/8 + 2/8 = 3/8

Rachel ate 3/8 of the pizza in total from pepperoni pizza and cheese pizza.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that Rachel ate 1/8 of the pepperoni pizza and 1/4 of the cheese pizza.

The total pizza eaten will be calculated as,

1/4 = 2/8

1/8 + 2/8 = 3/8

Hence, Rachel ate 3/8 of the pizza in total from pepperoni pizza and cheese pizza.

Answer:

A .x+y=150 y=x+80

B. x=35 y=115

x + (x + 80) = 150

2x + 80 = 150

2x = 70

x =35 practicing the guitar

then put x back in to solve for y

C. no because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

Step-by-step explanation:

this is my first time answering a question so hope it helps :)

A pair of linear equations to show the relationship between the number of minutes ;

x=Max practices the guitar

y= the number of minutes he practices the piano

x+y=150

y=x+80

The time does Max spend practicing the piano every day:

Subsitute x back in to solve for y.

x+y=150  

35+y=150

y=115

No , it is not possible because that is a whole 10 minutes more so it would be for 160 minutes of practice instead.

Answer:

Step-by-step explanation:

Answer:

c

Step-by-step explanation:

The plot of a function f(x) is symmetric across the y-axis if it is even, meaning f(-x) = f(x) for all x in the function's domain.

The answer is then A because

(-x)² = (-1)² x² = x²

|-x| = |-1| |x| = |x|

cos(-x) = cos(x)

The answer is not

• B because sin(-x) = -sin(x) and (-x)³ = (-1)³ x³ = -x³

• C because -x ≠ x and again because of x³

• D because 1/(-x) = -1/x and again because of sin(x)

Step-by-step explanation:

38 because there are 2 choices true or false so if there are 19 questions each question would have 2 choices and if selected both same with all the other ones if there are 19 questions each and 2 choices for each question then multiply it by 19*2 and you get 38. Simple!

There are 4 drops in temperature.

1.9 x 4 = 7.6 total temperature drop.

54.7 - 7.6 = 47.1 F temperature

1.9 x 4 = 7.6 total temperature drop.

54.7 - 7.6 = 47.1 F temperature

Answer:

4.397 * 10⁹

Step-by-step explanation:

(3.700 * 10⁹) + (6.970 * 10⁸)  = (3.700 * 10 * 10⁸ ) + (6.970 * 10⁸)

                                             = (37.00 * 10⁸) + (6.970 * 10⁸)

                                             = (37.00 + 6.970) * 10⁸

                                             = 43.97 * 10⁸

                                             = 4.397 * 10 * 10⁸

                                              = 4.397 * 10⁽¹⁺⁸⁾

Answer: 20%

Step-by-step explanation:

(part / whole) * 100

(3 / 15) * 100 = 20%

The skirts have been reduced to 20% of their original price.

You are looking for the percentage of the original price that the new price is. This means that you are looking for what percentage of $15 that $3 is:

= New price / Original price x 100%

= 3 / 15 x 100%

= 1/5 x 100%

= 20%

The skirts have therefore been reduced to 20% of their original price.

Answer:

Options (2) and (4)

Step-by-step explanation:

Option (1)

The slope of the graph is 60.

From the graph attached,

Slope = [tex]\frac{\text{Rise}}{\text{Run}}[/tex]

         = [tex]\frac{-210}{3.5}[/tex]

         = - 60

False.

Option (2)

y-intercept gives the initial distance, in miles from Exit 34.

True.

Option (3)

y-intercept of the graph is 3.5

Since, y-intercept of the graph is 210.

Therefore, Option (3) is False.

Option (4)

Slope gives the rate, in miles per hour, at which the distance to Exit 34 changes over time.

True.
