Answer:
0.392, independent
Step-by-step explanation:
Given that a certain type of flashlight requires two type-D batteries, and the flashlight will work only if both its batteries have acceptable voltages. Suppose that 90% of all batteries from a certain supplier have acceptable voltages.
For determining the probability we must assume that the batteries' voltage levels are independent
Let X be the no of batteries acceptable in the sample of 20 selected.
Then X is binomial because only two outcomes, and independence is assumed
Required proability = the probability that at least nineteen will work

Answer:
12, 18, 24, 30
Step-by-step explanation:
List the numbers between 11 and 34 that can be evenly divided by 3:
12, 15, 18, 21, 24, 27, 30, 33
Then eliminate the odd numbers, obtaining:
12, 18, 24, 30
These are the four busses that Camille could ride to work.
Answer:
1. 11
2. 20
3. 34
4. 12.6
5. 18
6. 105
Step-by-step explanation:
We are told that ---> t = 0, x = 1.5, y = 6, and z = 23
1. y + 5
= 6 + 5
= 11
2. z - 2x
= 23 - 2(1.5)
= 23 - 3
= 20
3. 2z - 2y
= 2(23) - 2(6)
= 46 - 12
= 34
4. 2.6y - 2x
= 2.6(6) - 2(1.5)
= 15.6 - 3
= 12.6
5. 4(y - x)
= 4(6 - 1.5)
= 24 - 6
= 18
6. 4(2 + z) + 5
= 4(2 + 23) + 5
= 8 + 92 + 5
= 105
