Answer:
speed
Step-by-step explanation:
In a distance-time graph:
Distance is the y-variable (dependent)
Time is the x-variable (independent)
The slope of a line is rise/run, or can also be calculated with this equation, where "m" is slope:
slope = y-variables / x-variables
slope = distance / time
If you divide distance by the time it took to get that far, you will find how fast you got there. This is called the speed.
You might also see this formula:
k = d/t
In the options, "time" and "distance" would not make sense, because those are the variables on the x-axis and y-axis.
Answer:
Change in productivity will be 50%
So option (b) will be correct option
Step-by-step explanation:
It is given that it takes 8 hour to bake 800 pretzels
And there is a shift of 8 hours
So hourly production =
Now the production is increases to 1200
Now hourly production =
So change in productivity = %
So option (b) will be correct answer
Answer: y = 3.5 x+ 43.8
Step-by-step explanation:
Here x represents the number of years after 1990
Thus, we get the table that is used to find the equation will be,
x 0 2 4 6 8
y 45 51 57 61 75
Let the equation that shows the above data,
y = b + a x ---------(1)
By the above table,
By substituting these values in the above value of a and b,
We get b = 43.8 and a = 3.5
Substitute this value in equation (1)
we get, the equation that shows the given data is,
y = 3.5 x + 43.8
⇒ Option (3) is correct.
