We are given the following statement; A number raised to a negative exponent is negative. We can go through experimental points. In this case, when the number is positive, the result is also positive. If the number is negative, we can say the result is negative.

Sometimes...

2^-3 = 1/(2^3) = 1/8

-2^-3 = 1/(-2^3) = -1/8

Which of the following can be modeled with an exponential function? Select all that apply.

bogdanovich [222]

Answer: The answers are

(ii) The cost to attend Universal Studios increases by 1% each year,

(iii) An endangered species population is decreasing by 12% each year,

(iv) The population of a town that is growing by 5% each year.

Step-by-step explanation: We are given five functions and we are to select those which can be modelled with an exponential function.

(i) Here, height is varying with respect to time, so it will be a linear function.

(ii) Here, the cost to attend Universal Studios is increasing by 1% every year, so this will be an exponential function.

(iii) Here, an endangered species population is decreasing by 12% each year.

So, this will also be an exponential function.

(iv) Since we are considering the distance travelled by the bicycle at a constant speed of 25 mph, so this will be a linear function.

(v) Here also the population is growing by 5% each year. So, the function will be exponential.

Thus, the correct answer is second, third and fifth.

"What is the probability that the next two employees that join the office staff will take the bus"

castortr0y [4]

Answer:

The correct option is A.

Step-by-step explanation:

Consider the complete question is "The table shows the transportation method used by the employees in an office.

Transportation Number of employees

Car 18

Bus 6

Walk 6

what is the probability that the next two employees that join the office staff will take the bus? A.0.04, B.0.12, C.0.33, D.0.36.

Total number of employees = 18 + 6 + 6 = 30

The probability that the employees take the bus = $\frac{6}{30}=0.2$

The probability that the employees that join the office staff will take the bus is

$Probability=(0.2)\times (0.2)=0.04$

Therefore, the correct option is A.
