One limitation of the Chi Square test (and all tests of hypothesis) is that they cannot tell us if relationships between variables are:_________ A. significant B. random C. by chance D. none of the above
The answer to the limitation of the Chi Square test (and all tests of hypothesis) about relationships between variables is none of the above.
What is the limitation of the chi square test?The Limitation of this type of test is in its sample size requirements, as there is a lot of difficulty of interpretation when samples are large.
Note that Chi Square test and all tests of hypothesis can tell us if relationships between variables are significant, random and also if it occurred by chance and as such they are no limitations here.
Therefore, option d is correct.

LeAnn is playing a math game. She chooses three cards. The value of each of her cards is shown.
First card: -12
Second card: 3
Third card: -5
What is the sum of the values of LeAnn’s three cards?
Answer:
-14
Step-by-step explanation:
The sum (addition) of the three numbers would be -14 because -12+-5 is -17. Then, -17+3 would be -14.

In a survey of 800 people, 42% said they shopped online last week. How many people said they shopped online last week?
336
explanation:
percent. part
_______ = _____
100. whole
42. ?
____ = ____
100. 800
cross multiply
800×42=33,600
then divide by 100
33,600/100=336
Answer:
336
Step-by-step explanation:
If 42% said they shopped online last week, that means the number of people who said they shopped online last week is 42% of 800. "Of" just means we should multiply, and since 42% = 42/100 (since % is just /100), we can use the following to find the answer (I used cross multiplication to simplify):
42 800 42 8
--- * = ---- * = 336

x^2+11x+28/x^2+5x+4 simplify expression
Answer:
(x + 7)/(x + 1)
Step-by-step explanation:
Simplify the following:
(x^2 + 11 x + 28)/(x^2 + 5 x + 4)
The factors of 4 that sum to 5 are 4 and 1. So, x^2 + 5 x + 4 = (x + 4) (x + 1):
(x^2 + 11 x + 28)/((x + 1) (x + 4))
The factors of 28 that sum to 11 are 7 and 4. So, x^2 + 11 x + 28 = (x + 7) (x + 4):
((x + 4) (x + 7))/((x + 4) (x + 1))
((x + 7) (x + 4))/((x + 4) (x + 1)) = (x + 4)/(x + 4)×(x + 7)/(x + 1) = (x + 7)/(x + 1):
Answer: (x + 7)/(x + 1)
Next time write the expression how it needs to be, the way you wrote it woould have given a toally different result.
x^2 + 11 x + 28/x^2 + 5 x + 4
Answer:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4 = x+7 / x+1
Step-by-step explanation:
solving this as you would in algebra 2:
x2+11x+28 / x2+5x+4
1. on both the top and the bottom you have to find a factor of the last number (in this case 28 and 4) that multiplys to be the number but adds to be the 2nd term (11x and 5x)
2. for the top the two terms would be (x+7) and (x+4). on thebottom half it would be (x+4) and (x+1)
** 7 times 4 equals 28, 7 plus 4 equals 11; 4 times 1 equals 4, 4 plus 1 equals
3. x+4 is common term on both the top side and the bottom half so you cross it out. this leaves us with our answer of: x+7 over x+1

Answer:
AB = 21
Step-by-step explanation:
the line EB is parallel to the side of the triangle DC and intersects the other 2 sides proportionally , that is
[tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex] ( substitute values )
[tex]\frac{14}{12}[/tex] = [tex]\frac{AB}{18}[/tex] ( cross- multiply )
12 AB = 14 × 18 = 252 ( divide both sides by 12 )
AB = 21
The group wants to travel from its current location on the map to the South Pole, and then directly back to the base camp. How many miles will they have to travel? Explain your answer.
Using the Pythagorean Theorem, it is found that the group will have to travel 90 miles.
What is the Pythagorean Theorem?The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:
[tex]h^2 = l_1^2 + l_2^2[/tex]
In this problem:
First, the group travels 5 x 5 = 25 miles to the south pole.Then, the distance to the camp is the hypotenuse of a right triangle with sides of 25 miles and of 12 x 5 = 60 miles, hence:[tex]d^2 = 25^2 + 60^2[/tex]
[tex]d = \sqrt{25^2 + 60^2}[/tex]
d = 65.
The total distance is given by:
Td = 25 + 65 = 90 miles.

An exam will have 20 questions worth a total of 100 points. There will be true-false questions worth 3 points each and short answer worth 11 points each. The students want to know how many of each type there will be on the test. The teacher won't tell. How many short answer questions are there?
Answer:
4 true false and 8 short answer
Or 15 true false and 5 short answer

Step-by-step explanation:
let x be the number of true-false questions
y be the number of short-answer questions
Then we have to solve the equation 3x + 11y = 100
Important: x and y are natural numbers
3x + 11y = 100 ⇔ 100 - 11y = 3x
If y=10 ⇒ 100 - 11×10 = −10 = 3x impossible because x ≥ 0
If y=9 ⇒ 100 - 11×9 = 1 = 3x impossible because x is a natural number
If y=8 ⇒ 100 - 11×8 = 12 = 3x ⇒ x = 12/3 = 4
Then (x,y) = (4,8) is a solution to the equation
If y=7 ⇒ 100 - 11×7 = 23 = 3x impossible because x is a natural number
If y=6 ⇒ 100 - 11×6 = 34 = 3x impossible because x is a natural number
If y=5 ⇒ 100 - 11×5 = 45 = 3x ⇒ x = 45/3 = 15
Then (x,y) = (15,5) is a solution to the equation
If y=4 ⇒ 100 - 11×4 = 56 = 3x impossible because x is a natural number
If y=3 ⇒ 100 - 11×3 = 67 = 3x impossible because x is a natural number
If y=2 ⇒ 100 - 11×2 = 78 = 3x ⇒ x = 78/3 = 26
Then (x,y) = (26,2) is a solution to the equation
If y=1 ⇒ 100 - 11×1 = 89 = 3x impossible because x is a natural number
If y=0 ⇒ 100 - 11×0 = 100 = 3x impossible because x is a natural number
Solve for x.

0.7p - 10
The jacket she decides to purchase has an original price of p=$87.99. What is the final price of the jacket Jenae is buying?
Answer:
$51.60
Step-by-step explanation:
This is essentially substitutionI have found that shops tend to round up the .99, so I will work with $880.7 × 88 - 10 = $61.60 - 10 = $51.60A newly formed life insurance company has underwritten term policies on 120 women between the ages of forty and forty-four. Suppose that each woman has a 1/150 probability of dying during the next calendar year, and that each death requires the company to pay out $50,000 in benefits. Approximate the probability that the company will have to pay at least $150,000 in benefits next year
The probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.
What is probability?It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.
The probability of dying:
P(dying) = 1/150
P(living) = 1 - P(dying) = 1 - 1/150 = 140/150
There are 120 women.
P(x≥3) = 1 - [P(x=0) +P(x=1) + P(x=2)]
[tex]\rm P(x\geq 3)=1-[(120 \ choose \ 0)(1/150)^0)((149/150)^{120})+[/tex]
[tex]\rm (120 \ choose \ 1) ((1/150)^1) ((149/150)^{119}) +[/tex]
[tex]\rm (120 \ choose \ 2)((1/150)^2)((149/150)^{118})][/tex]
P(x≥3) = 0.047
Thus, the probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

a tuba creates a 4th harmonic of frequency 116.5 hz what is the length of the pipe in the tuba
Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m
Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe
What is the frequency of an closed pipe?The frequency of a closed pipe f = nV/4L where
n = harmonic V = speed of sound and L = length of pipe in tubaLength of pipe in tubaMaking L subject of the formula, we have
L = nV/4f
Since the tuba creates the 4th harmonic with frequency 116.5 Hz.
n = 9 and f = 116.5 HzSubstituting the values of the variables into the equation, we have
L = nV/4f
L = 9 × 340 m/s/4 × 116.5 Hz
L = 3060 m/s ÷ 466 Hz
L = 6.57 m
So, the length of pipe in tuba is 6.57 m

give the answer
the areaaaaaa
Answer:
16
Step-by-step explanation:
The figure shown is a trapezoid
Area of a trapezoid = 1/2(bottom base length + top base length) × height
Bottom base length = 7 units
Top base length = 1 unit
Height = 4 units
So area = 1/2 ( 7 + 1 ) × 4
==> add 7 and 1
Area = 1/2 (8) × 4
==> multiply 1/2 and 8
Area = 4 × 4
==> multiply 4 and 4
Area = 16
What is the slope of the line?
Answer:
[tex]-\frac{2}{3} x[/tex]
Step-by-step explanation:
Hey there!
To find slope, you take [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
In this case
y2: 6
y1: 4
x2: -3
x1: 0
Now we plug in this information
[tex]\frac{6-4}{-3-0} \\\\\frac{2}{-3} \\\\-\frac{2}{3}[/tex]
Since this is the slope, you have to add a "x"
So, the slope is [tex]-\frac{2}{3} x[/tex]
