Answer:

Rate = 10%

Step-by-step explanation:

We are given with the following details.

Interest earned = $ 116.25

Principal = $ 1550

Interest Rate = r (say)

Time = 9 months

         = \frac{9}{12} years

We are asked to determine the rate of interest for which we can earn 116.25 interest. As we are not specifically given whether it is a compound or simple interest , we assume it to be simple interest and solve .

The formula for simple interest is given as

Interest = Principal \times Rate \times time

116.25=1550 \times r \times \frac{9}{12}

r= \frac{116.25 \times 12}{1550 \times 9}

r=0.1

Hence the r = 0.1

Hence the rate of interest is 10%

Suppose the amount of sun block lotion in plastic bottles leaving a filling machine has a normal distribution. The bottles are l
Gnom [1K]

Question:

Suppose the amount of sun block lotion in plastic bottles leaving a filling machine has a normal distribution. The bottles are labeled 300 milliliters (ml) but the actual mean is 302 ml and the standard deviation is 2 ml. If you purchase a package of 6 bottles of lotion, what is closest to the probability that at least one bottle has a content of less than 300 ml?

Answer:

0.645314

Step-by-step explanation:

Given:

Mean, u = 302

Standard deviation \sigma = 2

n = 6

Let's first find P(X>300):

Z = \frac{X - u}{\sigma}

Z = \frac{300 - 302}{2}

Z = -1

Using the standard normal table,

NORMSDIST(-1) = 0.158655

Thus,

P(Z<-1) = 0.158655

Find the closest to the probability that at least one bottle has a content of less than 300 ml:

Given that 6 bottles were purchased & p = 0.158655

Find:

P(X≥1) = 1 – P(X<1) = 1 – P(X=0)

Use bimonial distribution:

P(X=x) = ^nC_x*p^x*(1 - p)^(^n^-^x^)

P(X=0) = ^6C_0* 0.158655^0*(1 - 0.158655)^(^6^-^0^)

P(X=0) = 1*1* 0.841345^6

P(X=0) = 0.354686

Therefore,

P(X≥1) = 1 – P(X<1) = 1 – P(X=0)

= 1 - 0.354686

= 0.645314

The closest to the probability that at least one bottle has a content of less than 300 ml is 0.645314
