Answer:

Option C - drawing one card after the other is the dependent event.

Step-by-step explanation:

To find : Which of the following is an example of dependent events?

Dependent Events

Definition- Two or more events are dependent if the outcome of one event affects the outcome of the other.

So, one event "depends" on another, they are dependent.

From the given examples :

a. tossing a coin and spinning a spinner - They are independent events because there is no effect of one on another.

b. tossing a coin twice - It is not a dependent event because they tossed together so event of one not effect the other.

c. drawing one card after the other - It is dependent event because drawing of one card is one event and drawing another card after the first event happened is depend on the first event.

Therefore, Option C is correct.

if a 16 ounce nectar feeder concede about 80 hummingbirds a day how many hummingbirds would you expect to be able to feed with a

tekilochka [14]

In the given question, it is already given that the 16 ounce feeder can feed about 80 humming birds. It has to be found the number of birds that a 12 ounce feeder can feed.
Now coming back to the problem.
The number of humming birds that a 16 ounce feeder can feed = 80
The number of humming birds that 1 ounce feeder can feed = (80/16) * 1
       = 5 * 1
   = 5 birds
Then
The number of humming birds that a 12 ounce feeder can feed = (12 * 5) birds
   = 60 birds
So a 12 ounce feeder can feed 60 humming birds.

Simplify a•a²•a³ of the following

professor190 [17]

Answer:

a^6

Step-by-step explanation:

when multiplying exponents, add the exponents together. you can distribute to prove it, a^2 is a•a, a^3 is a•a•a so by bringing it together you get a•(a•a)•(a•a•a) which gets a 6 times or a^6

Situation:

Arturiano [62]

Answer:

t = 6162 years

Step-by-step explanation:

Apparently you are asked to use the constant k = 0.0001 instead of the most common 0.00012. We'll answer the problem using such number you typed, but make sure that there is no omission in your typing.

The equation to use is that for carbon decay:

$N(t)=N_0\,e^{-0.0001\,\,t}$

If the skull contains 54% of its original amount of C14, then that means that :

$N(t)=0.54 \,\,N_0$

we use this to solve for the time (t) in our equation:

$0.54\,\,N_0=N_0\,e^{-0.0001\,\,t}\\\frac{0.54\,\,N_0}{N_0}=e^{-0.0001\,\,t}\\0.54=e^{-0.0001\,\,t}\\ln(0.54)=-0.0001\,\,t\\t=\frac{ln(0.54)}{-0.0001} \\t=6161.86\,\,years$

which rounded to the nearest year as requested gives :

t = 6162 years

The spinner for a board game has eight colors the arrow can land on. What are the degrees of freedom for a goodness-of-fit test

Juliette [100K]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of colors that the arrow can land on = 8

We need to find the degrees of freedom for a goodness of fit test of the fairness of this spinner.

As we know that degree of freedom is 1 less than the size of sample.

So, Mathematically, it is expressed as below:

So, Degree of freedom would be

$v=n-1\\\\v=8-1\\\\v=7$

Hence, Option 'c' is correct.
