11. D) There appears to be an association between the variables. Since the teams with animal mascots win 74% of their games played and those with another type of mascot only win 49% of their games, the large difference suggests an association.12. A) 913. D) There appears to be an association. Since there is a difference in percentages for modern and classical styles for the type of art.14. D) 59%15. A) 60%=================================================
Explanations:
11. If the columns were identical (or nearly so) then that would suggest there isn't any association. However, the columns are different so it's likely we have association going on. Changing the mascot type appears to have an effect on whether the team wins or loses. In other words, the variables appear to be dependent.12. Let x be the missing value in the table. Solve the proportion x/18 = 27/54 and you should get x = 9. If 9 goes in that table, then it will produce identical row relative frequencies (and identical column relative frequencies as well) which would then lead us to conclude that there probably isn't any association between the variables.13. This is similar to problem 11. The columns being different percentages shows that changing the art style changes the make up of the sculptures and paintings. 14. There are 37+54 = 91 people who prefer the beach (instead of skiing). Of this total, 54 are away from the coast. So roughly 54/91 = 0.59 = 59% of the beach-goers are away from the coast.15. Same idea as the previous problem. We have 24+36 = 60 people who like to ski, and 36 people are away from the coast. So 36/60 = 0.60 = 60% of the skiers are away from the coast.Related Questions

How many solutions exist for the system below? In two or more complete sentences, give the solution and explain how you solved the system. y=-2x + 3 y = -2×3x
Answers
Answer:
See below
Step-by-step explanation:
y=-2x + 3
y = -2*3x
Both equations are lines.
Two lines will intersect at one point
I will set the two equations equal and solve for the x coordinate.
-2x+3 = -6x
Add 2x from each side
3 = -4x
Divide by -4
-3/4 = x
Now find y
y = -6x
y = -6(-3/4)
y = 18/4 = 9/2
The solution is ( -3/4, 9/2)

Answer:
Choice C
Step-by-step explanation:
$80 to 5 hours
Divide both numbers by 5 to find the unit rate:
$16 to 1 hour, or 16 to 1
For x hours, the pay, y, is y = 16x.
Choice A is true.
Look at choice B.
When x = 5, y = 80.
This is correct because we are given that information.
The process is to multiply the hours by 16.
For x hours, y = 16x (from choice A)
For x = 7, y = 7 * 16
Choice B works.
Look at choice C.
We need a proportion. The left side is the ratio 80/5, meaning $80 for 5 hours of work. Notice that the first number in the ratio is dollars, and the second number is hours. Now we need another ratio written in the same order to set up a proportion. x dollars is to 7 hours. This is the ratio x/7. The correct proportion is
80/5 = x/7
Choice C is 80/5 = 7/x
Choice C is incorrect.
Look at choice D.
The graph shows that for 5 hours, the pay is $80, so by looking up x = 7, you can find the correct amount of pay.
Choice D works.
Answer: Choice C

Answer:
a) x = -10
b) x = 7
Step-by-step explanation:
a)
2(x + 3) = x - 4
2x + 6 = x - 4
2x - x = -4 - 6
x = -10
b)
4(5x - 2) = 2(9x + 3)
20x - 8 = 18x + 6
20x - 18x = 6 + 8
2x = 14
x = 7
2x+6=x-4
2x-x=-4-6 (collecting like terms)
x=-10
b. 4(5x-2)=2(9x+3)
20x-8=18x+6
20x-18x=6+8 (collecting like terms)
2x=14

Aubrey filled her pool 0.9 of the way with water. Water evaporated from the pool at a rate of 7.5ft ^ 3 per day.
Answers
Answer: hello your question lacks vital data hence I will provide you with a general equation within the scope of your question
answer :
General equation = ( Stiver and Mackay or EPA ) evaporation equations
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
Step-by-step explanation:
Given data
volume of water in pool = 0.9 i.e. 90% full
rate of evaporation = 7.5ft^3 per day = 56.1039 gallons / day
Assumption :
Volume of pool = 16,000 gallons
In order to resolve the missing part of the problem apply the equation below
E = [tex]\frac{PAW}{T +459.67}[/tex] or E = [tex]\frac{7.4PA(0.447W)^{0.8} }{T + 459.67}[/tex]
where : E = Evaporation rate , P = water's vapor pressure , A = pool surface Area , W = wind speed , T = Temperature in Fahrenheit

Jill says that the rules for multiplying and dividing integers are alike. Do you agree? Explain.
Answers
Answer:
The rules of dividing integers are similar to the rules of multiplication
The only difference in division is that the quotient may not necessary be an integer. Hence, when dividing two integers with like signs, we divide the numbers without sign and place a positive sign to the result.
Answer:
I do not agree
Step-by-step explanation:
because in multiply negatives, the 2 negatives turn into a positive or multiplying positive and negative (and vice versa) becomes a negative still so the rules of multiplying and dividing are not alike integers. (For dividing it is the same)

Step-by-step explanation:

The value of x is incorrect he should be using 28/21 instead of 21/28
Answer:
A) The value of x is incorrect. He should be using 28/21 instead of 21/28.
Step-by-step explanation:
Recall that [tex]tan\theta=\frac{opposite}{adjacent}[/tex]. This means that the correct setup would be [tex]tan\theta=\frac{28}{21}[/tex] since 28 is opposite of x° and 21 is adjacent to x°. Thus, your solution would be [tex]x^{o}=tan^{-1}(\frac{28}{21})=53.13010235^o\approx53.1^o[/tex]

y2 = 3
y1 = 8
D = sqrt( -5 - 1)^2 + (3 - 8)^2 )
D = sqrt( (-6)^2 + (-5)^2 )
D = sqrt( (36 + 25)
