If it's 3 or 4 the probability is:

2/6 or 1/3

We call the outcomes in an event its "favorable outcomes". If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is .

State whether the growth (or decay) is linear or exponential, and answer the associated question.

Gekata [30.6K]

Answer:

The growth is linear.

It will be worth $124,500 in three years.

Step-by-step explanation:

The value of a house is increasing by $1500 per year.

Fixed increase, that is, each year the value increases the same. So the growth is linear.

Value after t years:

The equation has the following format:

$V(t) = V(0) + a*t$

In which V(0) is the current value and a is the yearly increase.

The value of a house is increasing by $1500 per year. It is worth $120,000 today.

Then $V(0) = 120000, a = 1500$

$V(t) = V(0) + a*t$

$V(t) = 120000 + 1500*t$

What will it be worth in three years?

This is V(3).

$V(t) = 120000 + 1500*t$

$V(3) = 120000 + 1500*3$

$V(3) = 124500$

It will be worth $124,500 in three years.

Juanita has saved 30% of the money that she needs to buy a new bicycle.

Mnenie [13.5K]

well, the bicycle costs "x" which is the 100% of its price, we know she has 30% thus far, and we also know that that is 66 bucks.

$\begin{array}{ccll} amount&\%\\ \cline{1-2} x&100\\ 66&30 \end{array}\implies \cfrac{x}{66}=\cfrac{100}{30}\implies \cfrac{x}{66}=\cfrac{10}{3} \\\\\\ 3x=660\implies x\cfrac{660}{3}\implies x=220$

What is 5,000 x 60 x 2

goldenfox [79]

Do it as simply as possible. 5000 × 2 = 10000. 60 × 10000 = 600000. Because multiplying by a factor of 10 is the easiest possible, always try to get a factor of 10 every time.
