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.

A student runs 7 km in 2 hours to train for sports. What is the student’s average speed?
Answer:
Step-by-step explanation:
For every hour said student would've ran 3.5 km/hr
7/2=3.5 kilometers per hour or 3 1/2 kilometers per hourDoes 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.

Answer: 28 degrees
Step-by-step explanation:
Since angle KJL = LJM then that means angle 7x=3x+16
First we need to solve for x
7x=3x+16
4x=16
x=4
now we can input it into either equation to solve for the angle KJL
7(4)= 28 so the angle is 28 degrees

9.17A boat traveled at an average speed of 27 miles per hour for 2 hours after first leaving the dock and then traveled at an average speed of 65 miles per hour for 4.5 hours. What is the total distance in miles the boat traveled?
A. 98.5 miles
B. 54 miles
C. 346.5 miles
D. 292.5 miles
Answer:
C
Step-by-step explanation:
27 miles for 2 hours so u add 27 + 27 = 54 than it says 65 miles per hour and travels for 4.5 hours so do 65 x 4.5 = 292.5 than add 54+292.6 and you will get the final answer wich is 346.5

Allison is saving to buy a $500 bicycle by working during
summer vacation,
• The job pays her $8 for every 1 hour worked.
• Allison works exactly 20 hours each week.
If she works for 4 weeks and buys the bicycle, how much
money will she have left over?
Answer:
140.00
Step-by-step explanation:
20 x 4 = 80 hours worked
80 x 8.00 = $640.00
640.00 - 500.00 = 140.00

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:

For the first box, you would multiply.
For the second box, you would multiply both sides by 3/2.
For the third box, the answer is 18.
[tex]\frac{2}{3}x=12[/tex]
[tex](\frac{3}{2} )*\frac{2}{3}x=12*(\frac{3}{2})[/tex]
[tex]x = 18[/tex]
If you have any further questions, please reach out to me :)
Answer:
multiply both sides by 3/2. The correct answer is 18

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (negative 5, 8), has a vertex at (negative 3, 4), and goes through (negative 1, 8).
Which best describes the transformation that occurs from the graph of f(x) = x2 to g(x) = (x + 3)2 + 4?

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

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.

20% of $30 = $24
30% of $24 = 16.8
40% of $35 = $21
Explanation:
0.2 x 30 = 6
30 - 6 = 24
0.3 x 24 = 7.2
24 - 7.2 = 16.8
0.4 x 35 = 14
35 - 14 = 21
