Amani computed in a two-way table the relative frequencies of sales of homes listed with two different real estate companies.
Which statement best describes the relationship between the two variables?
A) There is an association because the relative frequencies by column are similar.
B) There is an association because the relative frequencies by row are similar.
C) There is no association because the relative frequencies by column are similar.
D) There is no association because the relative frequencies by row are similar.
The answer the third option.
When you look at the data, in the first column, the frequency of sales of both are similar. Even the second column shows similar data. Association is determined if there is a significant difference between the data in each column/row depending on what you are aiming to answer.
In this case, we look at it per column because you want to compare the frequencies of sales of each company which are aligned by columns. So we know to look at the columns and not the rows.

Terry is buying juice. He needs 3 liters. A half-liter of juice costs $2.39. A 250-milliliter container of juice costs $1.69. What should Terry buy so he gets 3 liters at the lowest price? Explain.
1. What are the two units of measurement used in this problem?
2. What do you need to do to the prices before you can compare the costs?
3. How can you convert the half-liter price to cost per liter? Explain.
4. How many 250 milliliter bottles are in 1 liter? Explain.
Answer:
Terry should buy the half liters.
1. Milliliters and Liters
2. For the milliliters you must multiply them by 12 because each milliliter container needs to be multiplied by 12 to have 3 liters, and for half liters, you must multiply the cost by 6 because there are 6 half liters in 3 liters.
3. You can convert the half liters to cost the same as the liters by multiplying them by 2 since 2 halves is 1 entire liter.
4. 1000 milliliters in 1 liter.
Step-by-step explanation:
Terry should buy the half liters because 6 half liters (equivalent to 3 liters) is $14.34, compared to 12 250 milliliter containers (equivalent to 3 liters) is $20.28.

Answer: X=4
Step-by-step explanation:
Because the 90 angle is alternate exterior angle to the 21x+6. So they are equal to each other. It would be 90=21x+6. Then -6 to both sides to be 84=21x and 84/21 is 4. So X=4.
2 x 3 to the power of two x 5 is the prime factorization for what number?
Hey there!
2 × 3^2 × 5
= 2 × 3 × 3 × 5
= 2 × 9 × 5
= 18 × 5
= 18 + 18 + 18 + 18 + 18
= 36 + 36 + 18
= 72 + 18
= 90
90: 2, 3, 3, & 5
Prime Facrorization of 90:
2 × 3 × 3 × 5
Thus, your answer is: 90

Math isn't my strongsuit pt.2 (Redo ez)
Answer:
D) 5
Step-by-step explanation:
1) Substitute:
6(p - q) : (p - 1) = 6 ( 13 - 3 ) : ( 13 -1 ) = 78 - 18 : 12 = 60 : 12 = 5
Note: Since we know that p=13 and q=3, we just need to replace it and calculate. Hope it helped, good luck! <3
Answer:
5
Step-by-step explanation:
Entering the values for p and q makes the equation:
6(13-3) / (13-1)
Solving this in order of operations means subtraction is first:
13-3=10 13-1=12
next multiply
6(10)= 60
then divide
60/12=5

In 1983 about 17,000,000 visitor hours were spent on boating. To the nearest million, about how many hours were spent on fishing? (right screenshot)
Answer:
20,159
Step-by-step explanation:
In 1983, there was a total of 37,159 million people fishing and boating. To find out only fishing, we need to subtract the 17,000 million people who boated (37,159 - 17,000 = 20,159) Now we know how many people fished in 1983, 20,159 million people.

Solve for x.
5x−2>8
Drag and drop a symbol and number into the boxes to correctly complete the inequality.
Answer:
The answer is greater than 2
Step-by-step explanation:
5x – 2 > 8
5x – 2 + 2 > 8 + 2
5x > 10
5x/5 > 10/5
x > 2
Thus, The value of x is greater than 2
-TheUnknownScientist 72
Step-by-step explanation:
First, we need to isolate x, or put it on one side of the inequality with nothing else. To do this, first add 2 to both sides. We add 2 because it is the opposite of subtracting 2, which is what is happening in the inequality; 5x -2 >8. So:
5x -2 > 8 = 5x > 10
+2 +2
Now, to get x by itself, we must divide by 5, because it is the opposite of multiplying by 5 (remember, when there is a number next to a variable, it means multiply. So, 5x is the same as 5 * x or 5 times x). So:
5x > 10 = x > 2
÷ 5 ÷ 5
So now that x is all alone on one side, we have successfully simplified this equation.
Answer:
So, x > 2

An amusement park sells child and adult tickets at a ratio of 8:1. On Saturday they sold 147 more child tickets than adult tickets. How many tickets did the amusement park sell on Saturday?
Answer:21 adult tickets and 168 children tickets
Step-by-step explanation:
Answer:
They sold 21 adult tickets and 168 children's tickets.
Step-by-step explanation:
Let x = number of adult tickets
Then,x+147 = number of children's tickets
8/1 = (x+147) / x
x + 147 = 8x
7x = 147
x = 21
Places a and b are 80km apart. car x starts at a and car y starts at b. if the cars travel in the same direction(car x moving towards b) with different uniform speeds, they meet each other after 4 hours from the start of their journey. if they travel towards each other, they meet in 2 hours.find the speed of car x
Please help :)
Answer:
hope it helps
Step-by-step explanation:
Let the speed of car starting from A=x km/hr and speed of car starting from B=y km/hr.The relative speed of A with respect to B when moving in the same direction =x−y km/hr.The relative speed of A with respect to B when moving in opposite direction =x+y km/hr.Distance between A and B=80 km.We know, Time=SpeedDistanceFrom the above information, we have,x−y80=8andx+y80=1+6020=34or,x−y80=8⇒10=x−y⇒x−y=10....(i)Also,x+y80=34⇒240=4(x+y)⇒x=60−y....(ii)Substituting (ii) in (i), we get,x−y=10⇒60−y−y=10⇒60−2y=10⇒2y=50⇒y=25Substituting y=25 in equation (ii), we get,x=60−y⇒x=60−25⇒x=35Thus, the speed of car starting from A=x=35 km/hr and speed of car starting from B=y=25 km/hr.
