You start at the y axis and go down 7 so the coordinate is (0, 7) then you move to the right five spaces from (0, 7) and go up 4 from the spot you moved right 7. This should have a positive slope
Answer: (-4, -1)
Step-by-step explanation: Since these lines are already graphed, we are looking for their point of intersection. This point where the two lines intersect will represent the x and y that is the solution to this system of equations.
The two lines intersect in quadrant III
where x and y are both negative.
When finding the coordinates of a given point,
be very careful with your signs.
Let's just do a quick review on the coordinate system. On the x-axis, left means negative and right means positive and on the y-axis, down means negative and up means positive.
So to find the coordinates for this point, we start at the origin.
Then we move to the left 4 and down 1 so that's (-4, -1).
So the solution to this system is (-4, -1).
Answer:
Step-by-step explanation:
(a). The explanatory variables are the antioxidant group, the response variable is the result of the rate of colon cancer
(b)The design of the experiment is stratified Random sampling. I'll suggest there divided into equal group of 216 each.
(c). Double blind is when the people subjected to the experiment are not in the know if they're given placebo or the real antioxidant
(d) No significant difference mean, there is no convincing relationship that those that engage in using antioxidant have reduced colon cancer rate.
(e) Awareness of its history in family, age also.
Since he can drive 160 kilometers in 2 hours, we can divide 160 by 2 to get 80.
160/2 = 80
Then we can take 3.5 • 80
To get 280 kilometers
Hope I helped ^u^
Answer:
6c
Step-by-step explanation:
If the mean of the values in a data set is c, and each of the values in the data set
were multiplied by 6, the mean of the resulting data is 6c.
The reason is that, the number that multiplies all the data set can be factored and it becomes a multiplier of the mean of the original data set.
Therefore the new mean is 6c
