Answer:$6451.6 should be deposited.

Step-by-step explanation:

The principal was compounded monthly. This means that it was compounded 12 times in a year. So

n = 12

The rate at which the principal was compounded is 7.2%. So

r = 7.2/100 = 0.072

It was compounded for 3 years. So

t = 3

The formula for compound interest is

A = P(1+r/n)^nt

A = total amount in the account at the end of t years. A is given as $8000 Therefore,

8000 = P (1+0.072/12)^12×3

8000 = P(1+0.006)^36

8000 = P(1.006)^36

P = 8000/1.24

P = $6451.6

A manufacturing machine has a 10% defect rate.If 4 items are chosen at random, what is the probability that at least one will ha
vagabundo [1.1K]

Solution

Step 1

\begin{gathered} probability\text{ of defective p = 10\% = }\frac{10}{100}\text{ = 0.1} \\  \\ probability\text{ of not defective q = 1 - p = 1 - 0.1 = 0.9} \\  \end{gathered}

Step2

The probability that at least one will have a defect

= 1 - the probability that noon will have a defect

Step 3

Use the binomial distribution

\begin{gathered} =1\text{ - }^nC_rp^rq^{n-r} \\ n\text{ = 4, r = 0} \\  \\ =1-^4C_0(0.1)^0(0.9)^{4-0} \\  \\ =\text{ 1 - 1}\times1\times0.9\times0.9\times0.9\times0.9 \\  \\ =\text{ 0.344} \end{gathered}

Caroline rolls a fair dice 480 times. How many times would Caroline expect to roll a six?
Gnom [1K]
A fair die has 6 sides so a 1/6 chance for each number
So divide 480/6= 80
80 times for each number, 80 for 6
