6y = - x + 8
y = - 1/6x + 4/3
y intercept = 4/3
The company installs 5000 light bulbs with an average of 500 hours for each bulb. The standard deviation of 100 hours and distribution approximated by a normal curve. The percentage of bulbs that can be expected to last the period of time of less than 690 hours is 97.1%. This will make the answer to be C.
Answer: 6 feet describes the center, and 9 feet describes the spread
Step-by-step explanation:
The center of a data set is mostly considered as the median or the mean
Here mean is 6 (given). And median is also 6. As 6 is exactly at the middle of the data set. (When arranged in ascending order)
Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.
Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.
If you multiplied 2x3 you get the area of half of the whole figure. But to get the other portion I subtracted 4-3 and got 1, the I multiplied 5x1 and got 5. so the answer is 11in^2.

Solve for x :
4 - (2x + 4) = 5
1) x = -10
2) x = 5/2
3) x = 1/2
4) x = 6
<h3><u>Answer</u><u>:</u><u> </u></h3>
➛ 4 - 2x + 4 = 5
➛ 2x + 4 - 4 = 5
➛ 2x + 0 = 5
➛ 2x = 5
➛ x = 5/2
Thus, The value of x is <u>5/2</u><u>.</u><u> </u>
