A sequence of numbers begins with 12 and progresses geometrically. Each number is the previous number divided by 2.Which value can be used as the common ratio in an explicit formula that represents the sequence?

2
6
12

Answers

The common ratio is the current number divided by the previous. So the ratio is 1/2

The sequence is 12, 6, 3, 3/2, 3/4 ...

You can obtain any number multiplying the previous number times 1/2.

6 = 12 *(1/2)

3 = 6*(1/2)

3/2 = 3*(1/2)

Answer:

Common ratio = $(1)/(2)$

Step-by-step explanation:

A sequence that progresses geometrically has the first term as 12.

Each number is the previous number divided by 2.

so the sequence will be 12, 6, 3, 1.5...........

Explicit formula of a geometric sequence is given by

$T_(n)=a(r)^(n-1)$

Where $T_(n)$ = nth term of the sequence

a = first term

r = common ratio

and n = number of term

In this sequence common ratio = $\frac{\text{Successive term}}{\text{previous term}}$

= $(6)/(12)$

= $(1)/(2)$

Therefore, common ratio will be $(1)/(2)$

A probability experiment consists of rolling a fair 6 -sided die. Find the probability of the event below. rolling a number greater than 4

Answers

A six sided die has a 1 in 6 probability of rolling any number.
Out of the numbers 1, 2, 3, 4, 5, and 6, two numbers , 5 and 6, are greater than four.
This mean that out of six possibilities, two will be greater than four, so there is a 2 in 6 probability of rolling a number higher than 4. This can be simplified to 1 in 3.

The probability of rolling a number greater than four on a six sided die is 1 in 3, or 1/3

Final answer:

The probability of rolling a number greater than 4 on a fair 6-sided die is 1/3, calculated by dividing the number of successful outcomes (2, as only 5 and 6 are greater than 4) by the total number of outcomes (6 as it's a 6-sided die).

Explanation:

To find the probability of rolling a number greater than 4 on a 6-sided die, we first need to identify the total number of possible outcomes. Since it's a standard 6-sided die, this would be 6. Then, we consider the number of outcomes that fulfill the condition, which in this case is rolling a number greater than 4. This leaves us with 2 successful outcomes (5 and 6). Therefore, the probability of this event is calculated as follows:

Probability = Number of successful outcomes / Total number of outcomes = 2 / 6 = 1 / 3

So, the probability of rolling a number greater than 4 on a 6-sided die is 1/3.

Ginny is studying a population of frogs. She determines that the population is decreasing at an average rate of 3% per year. When she began her study, the frog population was estimated at 1,200. Which function represents the frog population after x years?

Answers

Answer:

$y = 1200(0.97)^x$

Step-by-step explanation:

Ginny determines that the population is decreasing at an average rate of 3% per year.

So, this is an exponential decay case

Formula : $y = a(1-r)^n$

where a is the amount after n years

a is the initial amount

r is the rate of depreciate

n is the number of years

Now we are given that When she began her study, the frog population was estimated at 1,200.

So, a=1200

r = 3% = 0.03

n =x

Substitute the values in the formula:

$y = 1200(1-0.03)^x$

$y = 1200(0.97)^x$

Hence function represents the frog population after x years is $y = 1200(0.97)^x$

Hello,

$x_(0)=1200$

$x_(1)=(97)/(100)*1200$

$x_(2)=((97)/(100))^2*1200$

$x_(3)=((97)/(100))^3*1200$
...
$x_(n)=((97)/(100))^(n)*1200$

HELP FAST PLEASE What is the value of the function at X=-3?
O y = 4
O y = 0
O y = 3
0y=-3

Answers

Answer:

To determine the value of the function at x = -3, we need to substitute -3 into the given function and evaluate it. Let's go through each option one by one:

1. y = 4: If this is the function, then substituting x = -3 would give us y = 4. However, this option does not match the given function.

2. y = 0: Substituting x = -3 into this function would give us y = 0. However, this option does not match the given function either.

3. y = 30: Substituting x = -3 into this function would give us y = 30. However, this option does not match the given function.

4. y = -3: Substituting x = -3 into this function would give us y = -3. This option matches the given function, so the value of the function at x = -3 is indeed y = -3.

Therefore, the correct answer is:

y = -3
