Answer:

Option A

Step-by-step explanation:

There are 6 total numbers on a six number dice.

There are 3 numbers that are greater than 3. [4, 5, 6]

$\frac{\text{Preferred Events}}{\text{Total Events}} =\frac{3}{6} =\frac{1}{2}$

The probability that you will roll a number greater than 3 is 1/2.

Option A should be the correct answer.

Answer:

1/2

There are three numbers above 3

And there are a total of 6 sides

Thus giving us 3/6

Simplify to get 1/2

Please help!! i have no idea!

Gemiola [76]

Answer:

θ = 60.34

Step-by-step explanation:

$\frac{\left(12.8\cdot \:sin\left(90\right)\right)}{sin\left(52.3\right)}$ = 16.177

$\frac{\left(16.177\cdot \:sin\left(90\right)\right)}{18.6}$ = θ = .869

$arcsin\left(.869\right)$ = 60.34

How to find compound rate from given values, 10 years after, and initial

dybincka [34]

The formula that calculates the compound rate from the given values is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

<h3>How to determine the compound interest rate?</h3>

The compound interest formula is:

$I = P(1 + \frac rn)^{nt} - P$

Where:

P represents the principal amount
r represents the compound interest rate
n represents the number of times the interest is compounded
t represents the time in years
I represents the interest

We start by adding P to both sides

$P + I = P(1 + \frac rn)^{nt}$

Divide through by P

$\frac{P + I}{P} = (1 + \frac rn)^{nt}$

Take the nt-th root of both sides

$\sqrt[nt]{\frac{P + I}{P}} = 1 + \frac rn$

Subtract 1 from both sides

$-1 + \sqrt[nt]{\frac{P + I}{P}} = \frac rn$

Multiply through by n

$r = n(-1 + \sqrt[nt]{\frac{P + I}{P}})$

In this case, t = 10

So, we have:

$r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

Hence, the formula that calculates the compound rate is $r = n(-1 + \sqrt[10n]{\frac{P + I}{P}})$

Katie’s baby sister drinks 4 ounces of apple juice with breakfast every morning. There was a full gallon of juice on the table.

Vlad1618 [11]

Answer: 112 oz

First we have to work with the same units. According to the International System of Units (SI), the Liter (L) is the unit of measurement for liquids, however, we are going to use the ounce (oz) in this case, as it is the unit of measure of the juice that Katie's baby sister drinks.

In addition:

$1L=33.814 oz$ (1)

$1 pint=0.5L\approx 16 oz$ (2)

$1 gallon=3.78 L\approx 128 oz$ (3)

Knowing this, we can calculate how much of apple juice is left for the baby after Katie drank a portion.

In order to do this, we have to substract the amount of juice Katie drank ( $1 pint\approx 16 oz$ ) to the total amount of juice in the full gallon ( $1 gallon\approx 128 oz$ ):

$128 oz-16 oz=112 oz$

This means that there are $112 oz$ left for Katie’s baby sister.

In addition, taking into account the baby drinks $4 oz$ each day, the $112 oz$ left are equivalent to approximately 28 days.
