The original number is 140
for this problem you will need to do a proportion
40/100 = 56/x
40x = 56 * 100
40x = 5600
40x/40 = 5600/40
x = 140
hope this help with other problems

The answer is
Step-by-step explanation:
f(x) & g(x) = f(x) + k
3•6 & 7•6 = 3•6 + k
18 + 42 = 18k
60 = 18k
Answer:
0.674
Step-by-step explanation:
If the random variable X is exponentially distributed and X has an average value of 25 minutes, then its probability density function (PDF) is
and its cumulative distribution function (CDF) is
So, <em>the probability that X is less than 28 minutes is
</em>
