Answer:

The probability that the next color will be red is: \dfrac{2}{3}

Step-by-step explanation:

The probability of an event is defined as:

Probability=(Total number of favourable outcomes)/(Total number of outcomes )

Here we have to find the probability that the next colour is red is given by:

<em>The recordings are given as:</em>

B  R  Y  R  R  R  R  Y  R  B  R  R

Number of outcomes that red will come up=8

Total number of outcomes=12

Hence the probability is given by:

Probability=\dfrac{8}{12}=\dfrac{2}{3}

You have$560 in an account which pays 4.8% compounded annually. If you invest your money for 8 years, then how many dollars of i
SCORPION-xisa [38]

Answer:

$ 254.85

Step-by-step explanation:

Total amount invested = $ 560

Interest rate = r = 4.8% = 0.048

Time in years = t = 8 years

The formula for compound interest is:

A =P(1+\frac{r}{n})^{nt}

Here,

A is the total amount accumulated after t years. P is the amount invested initially and n is the compounding periods per year. Since in this case compounding is done annually, n will be 1. Using the values in the above formula, we get:

A=560(1+\frac{0.048}{1})^{8} = \$ 814.85

Thus, the total amount accumulated after 8 years will be $ 814.85

The amount of interest earned will be:

Interest = Amount Accumulated - Principal Amount

Interest = $ 814.85 - $ 560 = $ 254.85

By the end of 8 years, $ 254.85 would be earned in interest.

3 hens in 1day lay=(1×3)/3

3 hens in 1day lay=1 egg

Third step is to determine the number of eggs 3 hens lay in 9 days

3 hens in 9 days lay=(1×9)

3 hens in 9 days lay=9 eggs
