Bytecoin is a new cryptocurrency that is currently valued at $243 per coin. You want to make an investment and purchase 1 Byteco

Digiron [165]

Answer:

Step-by-step explanation:

The growth rate of the coin is exponential. We would apply the formula for exponential growth which is expressed as

y = ab^x

y = b(1 + r)^ t

Where

y represents the value of the coin after x months.

x represents the number of months.

a represents the initial value of the coin.

b represents rate of growth.

From the information given,

a = 243

b = 1 + 15/100 = 1 + 0.15 = 1.15

Therefore, the exponential expression to determine the number of months, x it will take for the coin to attain a certain value, y is expressed as

y = 243(1.15)^x

If y = 1000, it means that

1000 = 243(1.15)^x

1000/243 = 1.15^x

4.115 = 1.15^x

Taking log of both sides, it becomes

log 4.115 = xlog1.15

0.614 = 0.061x

x = 0.614/0.061

x = 10 months

It will take 10 months

A standard number cube is rolled 288 times. Predict how many times a 3 or a 5 will be the result.

Anvisha [2.4K]

The events of rolling a 3 or a 5 are disjoint, so $\mathbb P\bigg((X=3)\cup(X=5)\bigg)=\mathbb P(X=3)+\mathbb P(X=5)$ .

Each face has a $\dfrac16$ probability of occurring, so the event of interest occurs with probability $\dfrac16+\dfrac16=\dfrac13$ . The number of times a 3 or 5 is rolled across 288 trials has a binomial distribution, $\mathcal B\left(288,\dfrac13\right)$ .

Recall that the expected value of a binomial distribution $\mathcal B(n,p)$ is $np$ . So in this experiment, we should expect to witness approximately $\dfrac{288}3=96$ instances of rolling a 3 or a 5.

A specific shade of green nail polish require some parts Bluetooth for parts yellow a mixture contains 42 quarts of red in 20 qu

Margaret [11]

Answer:

The answer is below

Step-by-step explanation:

The question is not correct, a similar question is:

A specific shade of red nail polish requires 7 parts red to 2 parts yellow. A mixture contains 35 quarts of red and 8 quarts of yellow. How can you fix the mixture to make the correct shade of red?

Solution:

A ratio is used in comparing amount of things, showing how the size of thing is compared to the other thing.

Given that:

$Ratio\ of\ red\ nail\ polish=\frac{7\ quarts\ of\ red}{2\ quarts\ of\ yellow} \\\\Ratio\ of\ red\ nail\ polish=\frac{7\ quarts\ of\ red}{2\ quarts\ of\ yellow}*\frac{4}{4} =\frac{28\ quarts\ of\ red}{8\ quarts\ of\ yellow}\\\\Ratio\ of\ mixture\ given\ =\frac{35\ quarts\ of\ red}{8\ quarts\ of\ yellow}\\\\\frac{28\ quarts\ of\ red}{8\ quarts\ of\ yellow}\neq \frac{35\ quarts\ of\ red}{8\ quarts\ of\ yellow}\\\\ \\$

Therefore to make the correct shade of red, an additional of 7 quarts of red is needed.

You are going to dinner and will order a drink, a main dish, and a dessert. The menu has 5 drinks, 6 main dishes, and 4 desserts

taurus [48]

Hello!

When finding total possibilities, you have to multiply every type of thing together.

There are 5 drinks, 6 main dishes, and 4 desserts.

You have to multiply all 3 of them together.

4 × 5 × 6 = 120

<u>120 different meals</u> can be made from a drink, a main dish, and a dessert
