Step-by-step explanation:
(3,1) y= x -2, <span> when x = 3, y = 3 -2 = 1 ....YES
</span>(1,3) y= x -2 , when x = 1, y = 1 -2 = -1 ....NO
(-1,3) y= x -2 , when x = -1, y = -1 -2 = -3 ....NO
(3,-1) y= x -2 , when x = 3, y = 3 -2 = 1 ....NO
answer is
<span>A-(3,1)</span>
Answer: 7881
Step-by-step explanation:
Given : A certain type of light bulb has an average life of 900 hours, with a standard deviation of 100 hours.
i.e.
Let x be the random variable that represents the length of life of the bulb .
Now , we find the z-score for this :
For x=820
Now, the probability that the length of life of the bulb is more than 820 hours is given by :-
Now, the number of bulbs installed in amusement park =10,000
Then , the number that can be expected to last more than 820 hours :-
