The answer is that 379-28..28
Answer:
100(1/a + 1/b)
Step-by-step explanation:
Machine A takes a hours to make 100 bolts
- Then machine A makes 100/a bolts in one hour
Machine B takes b hours to make 100 bolts
- Then machine B makes 100/b bolts in one hour
<u>Two machines will make:</u>
- 100/a + 100/b = 100(1/a + 1/b)
bolts in one hour
Answer:
a) P(X = 0) = 0.5997
b) P(X = 9) = 0.0016
c) P(X = 8) = 0.0047
d) P(X = 5) = 0.4018
Step-by-step explanation:
These following problem are examples of the binomial probability distribution.
Binomial probability
Th binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
In which is the number of different combinatios of x objects from a set of n elements, given by the following formula.
And is the probability of X happening.
(a) for n = 4 and π = 0.12, what is P(X = 0)?
(b) for n = 10 and π = 0.40, what is P(X = 9)?
(c) for n = 10 and π = 0.50, what is P(X = 8)?
(d) for n = 6 and π = 0.83, what is P(X = 5)?
Answer:
A. x = 15
Step-by-step explanation:
2x + 3 * (x - 10) = 45
2x + 3x - 30 = 45
5x - 30 = 45
5x = 75
x = 15
Because the distance a car travels is directly related to the time it travels, the distance varies directly with the time: d=a*t. "a" would be the constant of variation. Just substituted the given values(300 and 5) into the equation, and you would get 300=5a. Divide both sides by 5 and you get a=60. So, the constant of variation is 60
