Answer:
28.6, that is, about 29 are expected to be defective
Step-by-step explanation:
For each battery, there are only two possible outcomes. Either it is defective, or it is not. The probability of a battery being defective is independent of other betteries. So the binomial probability distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x sucesses on n repeated trials, with p probability.
The expected value of the binomial distribution is:
The probability that a battery is defective is 1/14.
This means that 
400 batteries.
This means that 
How many are expected to be defective?
28.6, that is, about 29 are expected to be defective
Answer:
D. 5/3
Step-by-step explanation:
10/6= 1.66666667, which is equivalent to 5/3
Answer:
9
Step-by-step explanation:
Let's say Mark is M and his brother is B.
M+5=B
M+B=23
Now we can solve using subsitution.
M+M+5=23
(Subtract 5 from both sides)
2M=18
M=9

Answer:
6 2/25 tons cement
Step-by-step explanation:
If cement mixer held 6 3/4 tons=6.75 tons
Mr. Folley used=0.67
After use cement are=6.75-0.67=6.08
So,
0.08=2/25
That's why answer is 6 2/25 tons
Answer: y=3x-8, y=5x-8, and y=2x-8
Step-by-step explanation:
These equations are all lines in slope-intercept form (y=mx+b where b is the y-intercept). y=3x-8, y=5x-8, and y=2x-8 all have -8 as the b value. Therefore, these equations have the same y-intercept.
