Answer:
Neither
Step-by-step explanation:
The slopes are not opposite and they are not equal either
line up 2x+3y=42 and -3x +2y=16
2x+3y=42=-3x+2y=16
get each term on one side and isolate.
If this is not possible, you have your answer. Another way to do this is graphing it and seeing if the two lines intersect, and if they do, if they make a right angle
Subtract 2x from both sides.
3y = - 2x - 12
Divide every term by 3 to get the y-variable by itself.
y = - 2/3x - 4
Since the equation is not in slope-intercept form (y = mx + b), your y-intercept is just the number in the b slot. Y-intercept is - 4 or (0, - 4).
Now to find your x-intercept, plug in 0 where the y-variable is and solve for x.
0 = - 2/3x - 4
4 = - 2/3x
Multiply both sides by - 3/2 to isolate the variable.
4(- 3/2) = x
- 12/2 = x
- 6 = x.
Your x-intercept is - 6 or (- 6, 0).
Answer:
tanA = sinA / cosA = 3/5 / 4/5 = 3/4.
Answer: D)0.205
Step-by-step explanation:
In binomial distribution, the probability of getting success in x trials is given by :-
, where n is the total number of trials , p is the probability of getting success in each trial .
Given : The probability that a component will fail is 0.2.
Let x be the number of components will stop working.
i.e. p=0.2
n=12
Since The machine will stop working if more than three components fail.
Then, the probability that the machine will stop working will be :-
Hence, the probability that the machine will stop working is 0.205.
Thus , the correct answer is D)0.205
