I think its either ounces or grams but I'm. not sure
If this is what u are asking for 240 is what i got for the answer
Is the question - did they mistakenly say "dollar" rather than "years?"
x = # of years
10,000 = 20,000 (0.85)^x, first divide both sides by 20,000
0.5 = (0.85)^x, next take the ln of both sides
ln 0.5 = ln (0.85)^x, by rules of logarithms you may move x to make it a coefficient of the logarithm
ln 0.5 = x (ln 0.85), divide both sides by ln (0.85)
x = (ln 0.5)/ (ln 0.85) = (-0.693)/(-0.1625) = 4.26 years
Answer:
149-1
Step-by-step explanation:
if you did 149-1 you'd get 148
Answer:
<u>The probability of accepting the lot if none in the lot are defective is </u><u>1</u>.
Step-by-step explanation:
A large lot of crankshaft bearings is accepted if 0 out of 7 are found defective. i.e. the probability of finding a defective crankshaft is 0.
Let X be the number of defective crankshafts. We need to find the probability that X=0. We will use the binomial distribution probability formula:
<u>P(X=x) = ⁿCₓ pˣ qⁿ⁻ˣ</u>
where n = total no. of trials
x = no. of successful trials
p = probability of success
q = probability of failure (1-p)
We have n=7, p=0, q=1.
P(X=0) = ⁷C₀ (0)⁰ (1)⁷⁻⁰
P(X=0) = 1
