3 1/4 times 4 is 16 then time 5 1/2 =71.5
Answer:
For first lamp ; The resultant probability is 0.703
For both lamps; The resultant probability is 0.3614
Step-by-step explanation:
Let X be the lifetime hours of two bulbs
X∼exp(1/1400)
f(x)=1/1400e−1/1400x
P(X<x)=1−e−1/1400x
X∼exp(1/1400)
f(x)=1/1400 e−1/1400x
P(X<x)=1−e−1/1400x
The probability that both of the lamp bulbs fail within 1700 hours is calculated below,
P(X≤1700)=1−e−1/1400×1700
=1−e−1.21=0.703
The resultant probability is 0.703
Let Y be a lifetime of another lamp two bulbs
Then the Z = X + Y will follow gamma distribution that is,
X+Y=Z∼gamma(2,1/1400)
2λZ∼
X+Y=Z∼gamma(2,1/1400)
2λZ∼χ2α2
The probability that both of the lamp bulbs fail within a total of 1700 hours is calculated below,
P(Z≤1700)=P(1/700Z≤1.67)=
P(χ24≤1.67)=0.3614
The resultant probability is 0.3614
1. 24%
2. 13%
3. 60%
1. Since 6/25 is .24, 24% of the class was absent
2. He spent 3 hours in total.. Divide is by 24 because there are 24 hours in a day. 3/24 is 0.125 for 13% of the day
3. He ran 3 of the 5 miles, so 3/5 = 0.6.. meaning 60%. The time doesn’t matter

Answer:
Step-by-step explanation:
An arithmetic sequence is when the difference of the terms is same
F)2, 5, 9, 14, ...
- 14 - 9 = 5,
- 9 - 5 = 4.
- 5-2 = 3
5 ≠ 4 ≠ 3, <u>no</u><u>
</u>
G)100, 50, 12.5, 1.6, ...
- 1.6 - 12.5 = -10.9
- 12.5 - 50 = -37.5
- 50 - 100 = -50
-10.9 ≠ -37.5 ≠ -50, <u>no</u>
H)3, 10, 17, 24,...
- 24-17 = 7
- 17 - 10 = 7
- 10 - 3 = 7
7 is the common difference, <u>yes</u>
j) -2,-1,-1/2,-1/4
- -1/4 - (-1/2) = 1/4
- -1/2 - (-1) = 1/2
- -1 - (-2) = 1
1/4 ≠ 1/2 ≠ 1, <u>no</u>
