Answer: True
Step-by-Step Explanation:
=> 2x + 3y = -7 (Eq. 1)
=> -x = 2y (Eq. 2)
=> x = 1, y = -3
Substitute values of ‘x’ and ‘y’ in Eq. 1 :-
=> 2x + 3y = -7
= 2(1) + 3(-3) = -7
= 2 + -9 = -7
=> -7 = -7
=> LHS = RHS
Therefore, it is a Solution.
Since 68% of the sample ranges from the plus minus first standard deviation from the mean, then interval wherein it will occur will be between 53.5% to 60.5%. I got this answer through adding and subtracting one standard deviation (3.5) from the mean (which is 57).
Answer:
x = 8
Step-by-step explanation:
Since you know that the line is 180 degrees in total, and there is a right angle, then you know . . .
180 = 90 + 40 + 6x + 2
Subtract 90 + 40 + 2 on both sides
48 = 6x
Divide by 6 on both sides.
x = 8
You have your answer.
