Answer:
Step-by-step explanation:
This could be an observational study because an experiment was not carried out by the research to further verify this hypothesis. Individuals are observed and data is collected from such observation. No effort is made by the researcher to affect the outcome of such results.
This study alone is not enough to conclude about a cause and effect relationship between steroids and the increase in home runs as thus study is not randomized and cant control other factors or links bringing about this result.
Answer: 65/100 or simplified
Step-by-step explanation:
Solve for x over the real numbers:2 x^2 - 3 x - 2 = x + 4
Subtract x + 4 from both sides:2 x^2 - 4 x - 6 = 0
The left hand side factors into a product with three terms:2 (x - 3) (x + 1) = 0
Divide both sides by 2:(x - 3) (x + 1) = 0
Split into two equations:x - 3 = 0 or x + 1 = 0
Add 3 to both sides:x = 3 or x + 1 = 0
Subtract 1 from both sides:Answer: x = 3 or x = -1
Answer: B and D are correct.
Step-by-step explanation:
A is wrong because they will eventually intersect (the arrows show that the line continues on).
B is correct; that is where they will intersect.
C is wrong because they only intersect at one point, and that's where the solution is.
D is correct because they intersect once and have only one solution.
Answer:
I will just give you the way of solving it
Step-by-step explanation:
First you have to change the sgape of the equation and it will become like this :
-6y=-2x+12
And then:
Y=0.33x+2
And then you have to give values to x and find y
For example i will make x zero (0)
It will become
Y=0.33(0)+12
=+12
And the points are (0,+12)
Go on like this and draw the line
Good luck
