Answer:
c. 8.25
Step-by-step explanation:
The given scenario corresponds to binomial experiment because
1. There are two possible outcomes i.e. each number can be working or not working.
2. On each dialing the probability of getting working cell number is p=0.55.
3. Cell phone numbers are randomly dialed so these are independent.
4. A pollster dialed 15 cell numbers i.e. n=15.
The mean number of calls that reach a working cell number can be calculated by computing mean of binomial distribution using the given information.
Mean of binomial distribution=E(x)=np
The mean number of calls that reach a working cell number=15*0.55=8.25
Thus, the mean number of calls that reach a working cell number=8.25
Answer:

Step-by-step explanation:
The sinusoidal function has a general form of:

The period is given by:

Y is the y-intercept, thus y = 3.
At the maximum value:

At the minimum value:

Therefore, the equation of the function described is:

Answer:
both problems are proportional
Answer:
B. 4
Step-by-step explanation:
To undo multiplication (which is what is being asked of us) you must divide. 28 divided by 7 is 4
so
4 x 7 is 28
If Brianna is taking care of 7 chickens, Tamara is taking care of 4 times the number of chickens because she is taking care of 28
