Adrian has 256 money by the end of month 4, at month 1 he had saved 4 dollars, use an exponent in an expression to represent how

ioda

Answer:

The required expression would be $4(4)^{t-1}$

Step-by-step explanation:

Since, the amount formula is,

$A=P(1+r)^t$

Where,

P = invested amount,

t = number of periods,

r = rate per period,

Given,

The invested amount at month 1, P = 4,

Number of periods from month 1 to month 4, t = 3

Amount at the end of fourth month, A = 256.

By substituting the values,

$256=4(1+r)^3$

$64=(1+r)^3$

$4=1+r$

$r = 4-1=3$

Hence, the amount of money at the end of t months.

$A=4(4)^{t-1}$

Nour and Rana are shopping for a Christmas tree. They are deciding between 222 different types of trees (real and fake) and 444

ioda

From what the statement says the question seems to be to represent the sample space of randomly choosing a type of tree and a color for the decorations

In this case, what we must do is identify the events that exist and the options that each event has, like this:

Event 1:

Tree type: real or fake

Event 2:

Colors for the ornaments: White (W), Silver (S), Gold (G) or Purple (P)

Since in an event there are 2 options and the other 4 options, the final number of options would be 2 * 4, that is, 8 options, represented below:

(real, W), (real, S), (real, G), (real, P), (fake, W), (fake, S), (fake, G), (fake, P)

The above would be the sample space of the events.

Now the probability of 1 coming out is 1 over the event total, or 1/8.
