For the following situations decide what type of chi square test is appropriate. Explain.
A random sample of 200 students was asked to sample a new type of pizza that the school was considering using as a replacement for the current pizza. Each student stated if they were a freshman, sophomore, junior, or senior and also if they liked the new pizza more than the current pizza (or not). The school would like to know if there is a relationship between grade level and pizza opinion.
Answer:
Following are the responses to the given question:
Step-by-step explanation:
In the given scenario, the Chi-square test is independent, which could be used because they would know whether it has any association among the several types of children like an old or new pizza. It does not associate discrete or factors that motivate with continuous data. In addition, only correlations among categorical data are evaluated inside the Chi-Square Independence Test, but causative inferential statistics cannot be given.
The type of chi square test that is appropriate for the following situation is Chi square test of independence.
What is chi square test of independence?Within the same population, the Chi-square test for independence looks for an association between two categorical variables.

The max Fuel capacity a spaceship should have is 500. The minimum is 200. The ship you are designing is rated at 75% of range. How much fuel capacity does it have? If, in the above example, we decide to change the max to 600, what is the new fuel capacity of the ship?
Answer:
Part 1: 375 Fuel Capacity
Part 2: 450 Fuel Capacity
Step-by-step explanation:
Find the percentage of each number with a calculator
375 fuel capacity does it have.
When decide to change the max to 600 new fuel capacity of the ship is 450.
Given that,
The max Fuel capacity a spaceship should have is 500.
The required 375 fuel capacity does it have.
When decide to change the max to 600 new fuel capacity of the ship is 450 determine,
How much fuel capacity does it have? If, in the above example, we decide to change the max to 600, what is the new fuel capacity of the ship.
According to the question,
The max Fuel capacity a spaceship should have is 500.
The ship you are designing is rated at 75% of range.
Full capacity is equals to max fuel capacity multiply by ship designing rate of range.
Therefore,
Fuel capacity = 500 × 0.75 = 375
And If the change in max fuel capacity to 600,
New fuel capacity is equals to new max fuel capacity multiply by ship designing rate of range.
Then.
New fuel capacity = 600 × 0.75 = 450
Hence, The required 375 fuel capacity does it have.
When decide to change the max to 600 new fuel capacity of the ship is 450.

A rock is thrown upward with a velocity of 12 meters per second from the top of a 28
meter high cliff, and it misses the cliff on the way back down. When will the rock be 5
meters from ground level? Round your answer to two decimal places.
Gravity Formula
PLS HELP
Answer:
The rock will be be 5 meters from ground level at time = 3.713 seconds
Step-by-step explanation:
As we know-
[tex]s(t) = -4.9 * t^2 + v_0t + s_0[/tex]
V0 = velocity
S0 = height above ground when thrown
Substituting the given values, we get -
[tex]9 = -4.9* t^2 + 12 * t +32\\-4.9*t^2 +12*t + 23 = 0[/tex]
As per the formula
[tex]t = \frac{-12+ \sqrt{12^2 -4*(-4.9)*23} }{(2*(-4.9)} \\t = 3.713[/tex]
The rock will be be 5 meters from ground level at time = 3.713 seconds

C. 25ab^2
D. 5ab^2
Answer:
The greatest common factor of 5ab^2 and 15ab^3 is 5ab^2
The greatest common factor between the two expressions will be 5ab²
What is the greatest common factor?
The greatest common factor is the largest positive number which can be divided into given numbers evenly.
Here the two numbers are:-
5ab² and 15ab³ or 5ab² and 5ab² x b
So we can see that the highest common factor between the two numbers will be 5ab².

Answer:
A (3, 4) B (4, 2) C (0.5, 0.25) D (1, 2.5) E (1.75, 4.25)
Step-by-step explanation:
The coordinate points of a point are (x, y) where x is the number on the x-axis and y is the number on the y-axis.
By looking at points A and B they're easy to tell.
For points C, D, and E they're in between whole numbers so by converting the number given which is a fraction you can get 0.25 from 1/4 which is half of 1/2, 0.5 from 1/2, 0.75 from 3/4 which is half of 1/2 plus 1/2, 1.25 from 1 1/4, etc....
Part A. Describe a relationship modeled by the function f(x) = 4x³ - 72x² + 320x, and explain how the function models the relationship.
Part B. Identify and interpret the key features of the function in the context of the situation described in part A.
Answer:A relationship modeled by the function f(x) = 4x³ - 72x² + 320x is the volume of a right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.
Explanation:
To find a relationship modeled by the given function it is recommendable to factor it.
The function is: f(x)=4x3- 72 x2+320x
The first step to factor it is to extract common factor 4x: f (x)=4x(x2-18=80)
The second step is to factor the quadratic trinomial.
That is made by writing it as a product of two binomials, for which the two constant terms add up - 18 and their product is 80. Those terms are -10 and - 8; so the two factors are (x - 10) and (x - 8), and the factored form is: f(x)=(4x)(x-10)(x-8)
Then, a relationship modeled by that polynomial is the volume of right prism whose dimensions are 4 times a desired length, 10 units less that such desired length, and 8 units less than the same desired length.
x is the desired (unknown) length
4x is 4 times the desired length
x - 10 is 10 less than the desired length
x - 8 is 8 less than the desired length
Thus, the volume of the prism is the product of the three factors:
Volume = (4x)(x-10)(x-8)

Answer:
7.8
Step-by-step explanation:
Identify sin cos or tan
In this case you would use tangent/tan
tan(∅) = opposite/adjacent
∅ (theta) = angle
plug in what you know to the tangent equation
tan(52) = 10/x
multiply both sides by x
x tan(52) = 10
divide by tan(52) on both sides
x = 10/tan(52)
enter 10/tan(52) in calculator
get 7.81285626...
nearest tenth = 7.8 units

Given the coordinates for the function below, who of the following are coordinates for its inverse?
Answer:
If we have a function f(x) that has an inverse g(x), we have the relations:
f( g(x)) = x
g( f(x)) = x
Then if the coordinates for the function f(x) are points like (x₁, y₁)
The coordinates for the inverse, g(x), will be (y₁, x₁)
Now let's look at the table, here we can see that the coordinates for f(x) are:
(0, 650)
(100, 550)
(200, 450)
(340, 310)
(650, 0)
Then the coordinates of the inverse function will be:
(650, 0)
(550, 100)
(450, 200)
(340, 310)
(0, 650)
What is the measure of angle A? How do you know this?
HELPPP QUICK ANSWER BOTH PARTS
Answer:
x = 20 degrees
Step-by-step explanation:
We know this because angles next to each other in parallelograms add up to 180 degrees, so if we create an equation, 3x + 120 = 180 meaning that 3x = 60, which means that x = 20 degrees.
The sum of the measures of three
angles is 90°
The measure of angle M is 2x
The measure of angle N is 3x + 8
• The measure of angle Q is 7x - 2
What is the value of x?
A. 7 B. 8
C. 9
D. 6
Answer:
A
Step-by-step explanation:
Equation
2x + 3x + 8 + 7x - 2 = 90
Solution
Combine like terms on the left
12x + 6 = 90 Subtract 6 on both sides
12x = 90 - 6
12x = 84 Divide by 12
x = 84/12

The volumes of two cubes are 32ft^3 and 1372ft^3
1. What is the ratio of their volumes?
2. What is the scale factor?
3. What is the ratio of their surface areas?
4. Find the surface are of the smaller cube if the larger cube has a surface area of 196ft^2
Answer:
1) 8 : 343
2) 42.875 or 42 ⅞
3) 4 : 49
4) 16ft²
Step-by-step explanation:
Volume of cube: s³
Surface area of cube: 6s²
_____________________
32ft^3 and 1372ft^3 →
32 : 1372 = 8 : 343
343 / 8 = 42 ⅞ = 42.875
s³ → 6s²
s³ = 8, s = 2, s² = 4.
s³ = 343, s = 7, s² = 49.
These are proportional so it is already in the simplest ratio so it is not necessary to multiply by 6.
s³ → 8 : 343
6s² → 4 : 49
(4 / 49) × 196ft² = 16ft²
