If you would like to solve the system of linear equations, you can do this using the following steps:
2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x
The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
Answer:
Answer is C
Step-by-step explanation:
(x + 6)(x + 2)
Answer:
Step-by-step explanation:
A. False. The probability of drawing a green marble twice is even smaller (It may be true though depending on what the question is asking, if it is asking the chance of drawing a green marble second is the same as the 1st chance, then yes it is True.
B.False
C. False
D.True, 1/3*1/3 (Simplified version of 6/18*6/18) is 1/9
E. False (Although this may be true, again depending on the type of question)
F. False
Answer:
C. Mean
A. The distribution is probably symmetric with a single peak.
Step-by-step explanation:
Mean measurement would give best description of the average number of car accidents people had in their lifetime. There are very less chances of skewed distribution because of the nature of the problem.
The data set in this case is not likely to have extreme variations thats why outliers wont be a problem. Therefore, mean measurement would be a better choice than median.
Example:
The typical data for this problem would look something like this.
2, 4, 4, 3, 5, 2, 1, 3
Mean= Sum of all elements/no. of elements

I attached a photo where I graphed these vertices in order to count the length and width. After counting the number of units between R & U I got a width of 4. And then I counted the units between S & T to get a width of 6. Using the formula to calculate the perimeter of a rectangle, P = 2(l+w). The perimeter is 20.
First I added the length plus the width, 4 + 6 and got 10. Then I did 10 x 2 which is how I got a perimeter of 20.
