Answer:
x = 5/4
y = 7/4
Step-by-step explanation:
The smaller triangle and the larger one are similar, so the sides are proportional.
(x+5)/5 = 10/8
x/5 + 1 = 1/4 + 1 . . . . . divide it out
x/5 = 1/4 . . . . . . . . . . .subtract 1
x = 5/4 . . . . . . . . . . . . multiply by 5
___
For y, you can do exactly the same computations, replacing every instance of 5 with a 7. Then you get ...
y = 7/4
Answer:
The probability that the bulb will last more than 1,200 hours is 0.3012
Step-by-step explanation:
Let the random variable <em>X</em> = life of a light bulb .
The random variable
The probability distribution function of exponential distribution is:
The mean of the distribution is, Mean = 1000 hours.
The value of λ is:
Compute the probability that the bulb will last more than 1,200 hours as follows:
Thus, the probability that the bulb will last more than 1,200 hours is 0.3012.
Let the smaller number be x and the larger be (x+19)
x+x+19=35
2x=16
x=8
x+19=27
the numbers are 8 and 27.
