A factory tests a random sample of 23 transistors for defects. The probability that a particular transistor will be defective ha
1 answer:
Answer:
0.496
Step-by-step explanation:
The probability that a particular transistor be deflective is 0.03. This situation may be seen as a experiment-result situation. You may choose one of the transistors and find out if it is deflective.
Be r the probability that a transistor selected be deflective. Be R the probability that the transistor selected don't be deflective; it is easy to note that R=1-0.03, due to the total of possibilities for the single experiment are two: deflective or not deflective.
If a single result has a probability of p, the probability P that the same result be obtained n times is:
So, the probability that none of the transistors be deflective is:

Answer:
1 seconds after being thrown, the stone reaches its max height
Step-by-step explanation:
The parabolic (quadratic) equation is:
Lets expand this in the form , so we have:
We can say the values of a,b, and c, now to be:
a = -5
b = 10
c = 40
The number of seconds at which the max would occur is given by the point, x, at:
We know a and b, let's find the seconds, x,
Hence,
1 seconds after being thrown, the stone reach its max height
Answer:
(D) 36%
Step-by-step explanation:
Actual cost of truck = $4500
Down payment = $1500
Money left to be paid = 4500-1500 = $3000
A = Monthly payments = 350
n = 10
Principal value (P) = 3000
Using formula,
A=
350 =
= 36% (approx)
Hence (D) is correct.
