2(x + 2) - 5 = 3(x  + 1) \\ 2x + 4 - 5 = 3x  + 3 \\ 2x - 1 = 3x  +  3 \\   - 1 - 3 = 3x - 2x \\  - 4 = x

You roll a 6-sided die two times. What is the probability of rolling a 4 and then rolling a 2? (Write your answer as a fraction
Delicious77 [7]

Answer:

1/36

Step-by-step explanation:

On the first throw, the probability of rolling any particular number, 1 through 6, is 1 out of 6. So the chance of rolling a 4 is 1/6.

On the second roll, your probability of rolling a 2 is 1/6.

The 'trick' is knwoing what to do with those two numbers.

Here's the rule: If events are dependent on one another, you multiply the probabilities.

Any time you see a scenario where X has to happen <u>and then </u>some other thing (X, Y, or whatever) has to happen, the events are dependent.

Probability of rolling a 4 <u>and then</u> rolling a 2 = 1/6 * 1/6 = 1/36

Hope this helps.

Zoe has $24 in a savings account. The interest rate is 5% per year and is not compounded. How much will she have to save in 4 ye
umka2103 [35]

Answer:

$28.8

Step-by-step explanation:

First we need to get the interest on the savings for the 4years. Since it is not compounded, we will use the simple interest (SI) formula.

According to the simple interest formula, SI = Principal × Rate × Time/100

Give principal = $24 rate = 5℅ time = 4years

SI = 24×5×4/100

SI = 480/100

SI = $4.8

Zoe interest for four years will be $4.8.

Amount she has saved for 4years = principal + interest = $24+$4.8

= $28.8
