Jessica opened a bank account that earns 2 percent interest compounded annually. Her initial deposit was $100, and she uses the
klasskru [66]

Answer:

x = 1.02.

Step-by-step explanation:

The x is a factor worked out from  the annual interest  written as a decimal fraction.

So we have  2% = 2/100 = 0.02.

The amount at the end of the first year is $100 + 0.02*100

= $100* 1.02,  and in  the second year it will be $100* 1.02^t  where t = 2 and so on.

So we see that x in the given expression is 1.02.

d1i1m1o1n [39]

Answer:

0.9855 or 98.55%.

Step-by-step explanation:

The probability of each individual match being flawed is p = 0.008. The probability that a matchbox will have one or fewer matches with a flaw is the same as the probability of a matchbox having exactly one or exactly zero matches with a flaw:

P(X\leq 1)=P(X=0)+P(X=1)\\P(X\leq 1)=(1-p)^{23}+23*(1-p)^{23-1}*p\\P(X\leq 1)=(1-0.008)^{23}+23*(1-0.008)^{23-1}*0.008\\P(X\leq 1)=0.8313+0.1542\\P(X\leq 1)=0.9855

The probability  that a matchbox will have one or fewer matches with a flaw is 0.9855 or 98.55%.
