Answer:
x = 2.5
y = 5
Step-by-step explanation:
2x + 3y = 20
2x + y = 10 then y = 10 - 2x
substitute for y:
2x + 3(10 - 2x) = 20
2x + 30 - 6x = 20
reduce:
-4x = -10
divide both sides by -4:
x = 2.5
y = 10 - 2(2.5) = 5
check:
2(2.5) + 3(5) = 20
20 = 20
and
2(2.5) + 5 = 10
10 = 10

Does association between variables mean that there is a cause-and-effect
relationship? Why or why not? Give an example.
Answer:
Yes
Step-by-step explanation:
Two variables may be associated without a causal relationship. For example, there is a statistical association between the number of people who drowned by falling into a pool and the number of films Nicolas Cage appeared in in a given year. However, there is obviously no causal relationship.

Given:
The equation is:
[tex]y=2x-3[/tex]
The x-values in the given table are -1, 1, 3.
To find:
The y-values for the given x-values in the table.
Solution:
We have,
[tex]y=2x-3[/tex]
At x=-1,
[tex]y=2(-1)-3[/tex]
[tex]y=-2-3[/tex]
[tex]y=-5[/tex]
At x=1,
[tex]y=2(1)-3[/tex]
[tex]y=2-3[/tex]
[tex]y=-1[/tex]
At x=3,
[tex]y=2(3)-3[/tex]
[tex]y6-3[/tex]
[tex]y=3[/tex]
Therefore the required table is:

The distance y (in miles) that Train A travels in x hours is represented by the equation y=68x . The graph shows the distance that Train B travels. (0, 0) and (1, 64).
Answer:
For train A, the distance traveled as a function of time in hours is written as:
y = 68*x
For train B, we know that it's equation passes through the points (0, 0) and (1, 64)
Remember that:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then the slope for the equation of train B is:
a = (64 - 0)/(1 - 0) = 64
Then equation of train B is something like:
y = 64*x + b
Now, we know that it passes through the point (0, 0), this means that when x = 0, we also have y = 0, then if we replace these two values in the equation we get:
0 = 64*0 + b
0 = 0 +b
then b = 0
This means that the equation for train B is:
y = 64*x
Where again, y is the distance in miles and x is the time in hours.
If we look at both equations, we can see that train A has a larger slope, which means that for each unit of time, train A travels a larger distance, then we can conclude that train A is faster than train B.
Rectangle garage length is 6.6 meters.The width is 6 times shorter then the length. What is the width?
Answer: width = 1.1 meters
Step-by-step explanation:
The length of Rectangle garage =6.6m
Width = 6 times shorter than length
Therefore width = 6.6/ 6
= 1.1 m

Calculate the length of the side LN given the following data for 37°.
Sin 37° = 0.602
Cos 37° = 0.790
Tan 37° = 0.754
pls help ASAP
Answer:
It is given that,
Sin 37° = 0.602
Cos 37° = 0.790
Tan 37° = 0.754
To find:
The length of side LN.
Solution:
In a right angle triangle,
[tex]\sin\theta =\dfrac{Perpendicular}{Base}[/tex]
Using this in triangle LMN, we get
[tex]\sin (37^\circ) =\dfrac{LM}{LN}[/tex]
[tex]0.602=\dfrac{6}{LN}[/tex]
[tex]0.602LN=6[/tex]
Divide both sides by 0.602.
[tex]LN=\dfrac{6}{0.602}[/tex]
[tex]LN=9.966777[/tex]
[tex]LN\approx 9.97[/tex]
Therefore, the correct option is C.
A linguist at a large university was studying the word length of papers submitted by students en
humanities programs. From a random sample of 25 papers, the linguist counted the number of words
used in each paper. The 95 percent confidence interval was calculated to be (20,995, 22,905).
Assuming all conditions for inference are met, which of the following is a correct interpretation of the
interval?
Answer:
We are 95 percent confident that the mean word length for all papers submitted by students in humanities programs is between 20,995 words and 22,905 words
Step-by-step explanation:
The confidence interval is used to predict the mean for the entire humanities program, not just the sample.

is -4.5 greater or less than 3?
Is -12/5 greater or less than 2?
From least to greatest order these: -3/2, -1, 11/4, 2, -3, 5.2, 0, 5.
(Btw I’m sorta new here so I apologize if I mess up)
Answer:
-4.5 is less than 3
-12/5 is less than 2
-3, -1.5, -1, 0, 2, 2.75, 5, 5.2
-3/2 = -1.5
11/4 = 2.75

share 350m in the ratio of 3:7
Answer:
105 , 245
Step-by-step explanation:
Ratio = 3 : 7
3x , 7x
3x + 7x = 350
10x = 350
x = 350/10
x = 35
3x = 3*35 = 105
7x = 7 *35 = 245

JKLM is a rectangle. if JL = 4x - 12 and MK = x, what is the value of x? what is the length of each diagonal?
Answer:
x = 4
The diagonals are both 4
Step-by-step explanation:
The fact that the two sides have no letter in common indicates that they are opposite each other or a diagonal. In this case the length is a diagonal. Diagonals in a rectangle are equal.
4x - 12 = x Add 12 to both sides
4x - 12 + 12 = x + 12 Subtract x from each side
4x - x = 12
3x = 12 Divide by 3
3x/3 = 12/3
x = 4
One of the diagonals = 4 because it is x.
