92 miles / 4 gallons = 23 miles per gallon
Because 1/4 is a fractional number, it is also a ratio which means it is Rational. :)
Answer:
What percentage of pick-up truck drivers want their next vehicle purchase to be another pick-up truck?
Should the speed limit be decreased on the highway connecting two large cities?
How many pedestrians would use a walkway built over a busy road?
Step-by-step explanation:
We use samples when using an entire population is not feasible.
It is not reasonable to ask every pick-up truck driver what they want their next purchase to be; there are too many owners of pick-up trucks. This means we should use a sample.
Many people drive a highway that connects two large cities. It is not reasonable to survey every person that drives it, so we should use a sample.
On a busy road, we may have many pedestrians; this means we should use a sample instead of the entire population.
Answer:
y + 1 = 3( x + 1)
Step-by-step explanation:
We are asked to find the equation of the line in point-slope form
Step 1 : find the slope using the two points given
( 0 , -3) ( 2,3)
m = (y_2 - y_1) / (x _2 - x_1)
x_1 = 0
y_1 = -3
x_2 = 2
y_2 = 3
Insert the values into
m = 3 - (-3) / 2 - 0
m = 3 +3 / 2 - 0
= 6/2
= 3
Step 2: it was given in the question that the parallel to a given line and passes through ( -1 , -1)
Substitute the point into the equation
y - y_1 = m ( x - x _1)
m = 3
y - y_1 = 3 ( x - x_1)
x_1 = -1
y_1 = -1
y - (-1) = 3( x - (-1)
y +1 = 3 ( x + 1)
We don't need to open the bracket because we are asked to give the answer in a point-slope form
The equation of the line in point slope form is
y + 1 = 3( x + 1)
Constant of proportionality, k, is the ratio of the quantity of variable y to the quantity of variable x.
Using a point on the line, (4, 44),
Constant of proportionality, k = .
Constant of proportionality of the graph is 11.
