Answer:
The answer is "Its results are not consistent with its three designs Yes. Its results show significant differences between both the three designs."
Step-by-step explanation:
Following are the distribution of preference:
[tex]Design 1 =54 \\\\ Design 2=38 \\\\\ Design 3=28 \\\\[/tex]
[tex]Design \ \ \ \ \ \ \ \ \ \ O_i \\ 1 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 54 \\2 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 38\\3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 28 \\Total \ \ \ \ \ \ \ \ \ \ 120[/tex]
An expected frequency([tex]E_i[/tex]) has 40 Null hypotheses to take n=120.to each design:
The effects of the three designs are standardized
Inaccurate.
Hypothesis Alternative:
The effects of the three prototypes are not uniform
Degrees Of freedom [tex]=(n-1)=(3-1)=2[/tex]
[tex]H_o, x^2 \ test\ statistic \ \sum_i {\frac{(O_i -E_i)^2}{E_i}} \\[/tex]
[tex]= \frac{(54 -40)^2}{40}+\frac{(38-40)^2}{40} + \frac{(28-40)^2}{40}\\\\=49+0.1+3.6\\\\=8.6[/tex]
Chi-squared distribution critical value at [tex]\alpha = 0.05 (x^2 _{0.052})=5.99[/tex]
Since [tex]x^2, a[/tex] value [tex]> x^2 -[/tex]table of [tex]\alpha =0.05 =5.99[/tex]is determined.
So[tex]H_o[/tex] is rejected.
help!!! im soo confused
Answer:
a=169 ft
Step-by-step explanation:
Here you are given the angle 25, and the opposite and hypotenuse values.
Opposite/Hypotenuse: the sin(angle 25)=a/400ft.
We need to solve for a, so lets multiply 400 to the other side:
400(sin25)=a. Plug this into your calculator and you will get the answer: a=169.04 ft

Matt works at a job where he makes a base pay of $200 per week and $50 per sale. (Use an x and a y. Y is the total amount he makes and x is the number of sales.)
: )
Answer:
y = 50x + 200
Step-by-step explanation:
the 200 is the y intercept because it is where his pay starts, so even if Matt doesnt make any sales he will still get 200 that week
the slope (50) is determined because that is what will change
if he makes 2 sales he will make 100 + 200 that week, and if he makes 4 sales he will make 200 + 200 that week and so on

Number [tex]4\frac{1}{2}[/tex] is not an integer number. The explanation is given.
What are integers?Any positive or negative number without fractions or decimal places is known as an integer, often known as a "round number" or "whole number."
Given:
[tex]4\frac{1}{2}[/tex]
Converting mixed fraction to improper fraction,
[tex]4\frac{1}{2}[/tex] = 9/2
An integer, which can comprise both positive and negative integers, including zero, is a number without a decimal or fractional portion.
A fraction that has the numerator higher than or equal to the denominator is said to be an improper fraction.
9/2 is an improper fraction.
Therefore, [tex]4\frac{1}{2}[/tex] is not an integer number.

Use the expression 9(7 + 2x) to answer the following:
Part A: Describe the two factors in this expression. (4 points)
Part B: How many terms are in each factor of this expression? (4 points)
Part C: What is the coefficient of the variable term? (2 points)
Answer:
Part A: Describe the two factors in this expression. (4 points) The factors are (1) the constant coefficient 9 and (2) the binomial (7+2x).
Part B: How many terms are in each factor of this expression? (4 points) The first factor (multiplicand), 9, has one term. The second factor (multiplicand), (7+2x), has two terms (and is thus called a binomial).
Part C: What is the coefficient of the variable term? (2 points) The only such coefficient is 2.

Given the points P(2, –6) and R(8, 3), what is the component form of Vector P R?
⟨6, -3⟩
⟨10, -3⟩
⟨6, 9⟩
⟨10, 9⟩
Answer:
C
Step-by-step explanation:
The component form of vector PR is ⟨6, 9⟩.
How to determine the component form of vector PRTo find the component form of vector PR, we need to subtract the coordinates of point P from the coordinates of point R.
The x-component of the vector is obtained by subtracting the x-coordinate of point P from the x-coordinate of point R:
x-component = 8 - 2 = 6
The y-component of the vector is obtained by subtracting the y-coordinate of point P from the y-coordinate of point R:
y-component = 3 - (-6) = 3 + 6 = 9
Therefore, the component form of vector PR is ⟨6, 9⟩.

You have $5.85 to buy bananas to make banana bread. A banana costs $0.39. Which inequality represents the number x of bananas you can buy?
Answer:
The inequality 0.39x ≤ 5.85 represents the number of bananas you can buy.
Step-by-step explanation:
Given that:
Amount of money you have to buy bananas = $5.85
Cost of each banana = $0.39
Number of bananas = x
You cannot spend more than $5.85, therefore, we will use less than or equal to symbol,
Cost of one banana * Number of bananas ≤ Total amount
0.39x ≤ 5.85
Hence,
The inequality 0.39x ≤ 5.85 represents the number of bananas you can buy.
A group of 12 students is deciding whether to go to the science center of the zoo. Science center tickets are 3 for $36.75 and zoo tickets are 4 for $51.
How much will a group of 12 students save by choosing the science center?
Answer:
147
Step-by-step explanation:
If they go to the science center it will cost 3 people 36.75 cents so for 12 people it would be 36.75*4=147( I think let me know if I am wrong).
