Which statements are true about exponential functions? Check all that apply.
babunello [35]
The following statements are true about exponential functions:
-The domain is all real numbers.
- The input to an exponential function is the exponent.
- The base represents the multiplicative rate of change.

The reason why the other two options are wrong are explained below:
The range of exponential functions is not always includes negative numbers; on the contrary, the range is the set of all positive real numbers.

The graph of an exponential function does not have a horizontal asymptote at x = 0; contrarily, the equation of the horizontal asymptote of the graph of is y = 0, which is the x-axis.

a jar contains ten black buttons and six brown buttons. If nine buttons are picked at random, what is the probability that exact
Anuta_ua [19.1K]

Answer:

33.04% probability that exactly five of them are black

Step-by-step explanation:

A probability is the number of desired outcomes divided by the number of total outcomes.

The order in which the buttons are chosen is not important. So we use the combinations formula to solve this question.

Combinations formula:

C_{n,x} is the number of different combinations of x objects from a set of n elements, given by the following formula.

C_{n,x} = \frac{n!}{x!(n-x)!}

Desired outcomes:

Five black buttons, from a set of 10

Four brown buttons, from a set of 6.

D = C_{10,5}*C_{6,4} = \frac{10!}{5!(10-5)!}*\frac{6!}{4!(6-4)!} = 3780

Total outcomes:

Nine buttons, from a set of 16.

T = C_{16,9} = \frac{16!}{9!(16-9)!} = 11440

Probability:

p = \frac{D}{T} = \frac{3780}{11440} = 0.3304

33.04% probability that exactly five of them are black

Step-by-step explanation:

Assuming that they are in the same time zones, you would

Convert the 12:50pm into 12:50am by adding 12 hours

Now just add the time from 12:50 to 2:05, which is 1 hour and 15 minutes
