Answer:

$q = 5.9$

Step-by-step explanation:

Add 3.6 to both sides.

$2.3 + 3.6 = q$

Simplify 2.3 + 3.6 to 5.9

$5.9 = q$

Hence, the answer is 5.9.

I have 3 green cubes, 4 red cubes, 2 black cubes, and 6 yellow cubes. What is the probability that I will randomly choose a blac

Strike441 [17]

Answer:

4/75 or 0.05333

Step-by-step explanation:

3+4+2+6=15 elements

2/15= probability to choose a black

6/15 = probability to choose a yellow cube

Probability to choose a black AND (*) a yellow = 2/15*6/15=12/225=4/75 or 0.05333

⦁ The population of the Tallahassee metropolitan area was 382,627 at the end of 2017 with a growth rate of 2.78%. Using the expo

a_sh-v [17]

Answer:

The exponential growth model for the population of the Tallahassee metropolitan area is $y=382627(1.0278)^t$ .

Step-by-step explanation:

The exponential formula is

$y=b(1+r)^t$

Where b is initial population, r is growth rate, (1+r) is growth factor and t is time (in years) after the initial year.

The population of the Tallahassee metropolitan area was 382,627 at the end of 2017. The growth rate is 2.78%.

Here the initial year is 2017 and rate is 0.0278

$y=382627(1+0.0278)^t$

$y=382627(1.0278)^t$

Graph of the equation is shown below. The x-axis represents the number of years after 2017 and y-axis represents the total population.

Difference between 2025 and 2017 is 8 years. Put t=8

$y=382627(1.0278)^8$

$y=476479.828188\approx 476479$

Therefore the projected population in 2025 is 476479.
