Answer:

$x = 8$

Step-by-step explanation:

${x}^{ \frac{1}{3} } = {32}^{ \frac{1}{5} }$

${( {x}^{ \frac{1}{3} } )}^{3} = {( {32}^{ \frac{1}{5} } )}^{3}$

${x}^{1} = \sqrt[5]{ {32}^{3} }$

$x = \sqrt[5]{32768}$

$x = 8$

E saca una bola de billar al azar de una caja que contiene 15 bolas de billar numeradas del 1 al 15 y se registra el número obte

Julli [10]

Answer:

P = 2/7 = 0.2857 or 28.57%

Step-by-step explanation:

First, we know that we have 15 balls, and we need to know which one of them is pair, and higher than 10.

So, we first need to calculate the probability that the obtained number is pair.

The pair numbers are 2,4,6,8,10,12,14

We have 7 numbers out of 15 ---> P(B) = 7/15

From those numbers, only two of them are higher than 10, which are 12 and 14, so: P(A|B) = 2/15

To get the probability to get a number higher than 10 and pair:

P(A/B) = P(A|B) / P(B)

P(A/B) = 2/15 / 7/15 = 2/7 = 0.2857

To get the percentage: 0.2857 * 100 = 28.57%.

Two accounts each begin with a deposit of $9000. Both accounts have rates of 3.1%, but one account compounds interest once a yea

Elodia [21]

<h3 />

Given : Initial deposit or the principal amount = $ 9000

Rate of interest = 3.1 %

Compound interest annually

= principal (1 + r/ 100)^t

here put value principal rate and time period 1, 5 10 and 20 years

and we get the amount for each time period

than for interest = amount - principal we get interest

as that we calculate all value:

<h3>When do we use compound interest ?</h3>

When interest on a balance in a savings or investment account is reinvested, you receive compound interest, which results in higher interest payments. Money makes money, a wise man once said. And money makes money by making more money. Compound interest speeds up the long-term growth of your savings and investments.
