Answer:
The probability is 0.44444.
Step-by-step explanation:
Among 9 electrical components exactly one is known not to function properly.
This means 8 components work properly.
If 4 components are randomly selected, the probability that at least one does not function properly is :
=
Answer: The probability is 0.44444.
Answer:
0.4444
Step-by-step explanation:
Use the following property to ease the calculation:
P(At least one)=1-P(None)
Total number of electrical components: 9
Number that does not function well :1
Number that functions well : 8
We have ways to to choose 4 good components from 8.
We have ways to choose 4 components from a total of 9.
If all function properly then none is bad, we way to do this.
P(At least one)=
P(At least one)=
P(At least one)=0.4444
Answer:
A)2100 ml
Step-by-step explanation:
Given total vinegar is 3 1/2 liters and the used vinegar is 3/5 of the vinegar in the beaker:
#First calculate the amount of vinegar not poured in the beaker:
#Calculate amount of vinegar used in experiment:
#The unused vinegar is therefore calculated by subtracting the used vinegar from the total at the start of the experiment:
Hence, the unused vinegar is 2100 ml
Using the monthly payment formula, it is found that the amount he will have to pay each month is of $649.45.
<h3>What is the monthly payment formula?</h3>It is given by:
In which:
In this problem, considering that the down payment does not count for interest, the parameters are given as follows:
P = 130000, r = 0.0438, n = 30 x 12 = 360.
Then:
r/12 = 0.0438/12 = 0.00365 -> 1+r = 1.00365.
Then the monthly payment is given by:
A = 649.45.
