Easy math
The square root of 10 is 2 witch means the pie of the root is 3.14 witch is equivalent to the square root of 2 equivalently is the answer to your question 3.14 pie
<u>The population in this setting is(A) All customers who have purchased something in the last year.</u>
<u></u>
Step-by-step explanation:
As it is given in the question that 1000 customers from the list of the customers who made a purchase last year.So the list refers to the population of the people who have made a purchase last year .
The 1000 customers are the sample of the population.
Dependent
The general form for a pair of linear equations in two variables x and y is
and
----- (1)
----- (2)
Comparing equations 1 and 2 with the general form of equation to write their co-efficient,
Compare the ratio,
If , then the pair of linear equations has exactly one solution.
So, it said to be consistent.
Answer:
(b) distance, y=20x, 480 mi
Step-by-step explanation:
As is often the case, the only self-consistent answer choice is the correct one.
__
The dependent variable is plotted on the y-axis, so is distance.
(x, y) = (2, 40) tells you y = 20x is an appropriate choice of equation.
In 24 hours, the dragonfly will fly y = 20(24) = 480 miles.
Answer:
-7/3
Step-by-step explanation:
When finding slope from a graph, I always look for places where the graph crosses grid intersections. One of these is the y-intercept, (0, 40).
You have to go quite some distance to find another. It looks to me like the next grid crossing is at (30, -30). At this point, you can do either of two things:
- find the ratio of grid squares
- use the slope formula
What you want to calculate is the ratio of the change in vertical height (rise) to the change in horizontal distance (run). If you use grid squares, you need to make sure the grid has the same number of units horizontally as vertically. (Here a grid square is 10 units in each direction, so we're OK on that point.)
We have observed that the line falls 7 grid squares vertically for a change of 3 grid squares to the right. So, the slope using grid squares is ...
m = rise/run = -7/3
Using the slope formula, we calculate the slope to be ...
m = (y2 -y1)/(x2 -x1)
m = (-30 -40)/(30 -0) = -70/30 = -7/3
The slope of the line is -7/3.
