The average frequency of people hearing the spot on the radio station is equal to 5.
Average frequency can be defined as the average number of times an individual is exposed to an Advertising schedule.
Average frequency can be calculated by using the formula;
average frequency = total / n
As 4000 people heard the spot 6 times and 2000 people heard it three times; therefore
n = 4000 + 2000 = 6000
total = number × frequency = (6 × 4000) + (3 × 2000) = 24000 + 6000 = 30,000
Substituting these values in the equation;
average frequency = 30,000 / 6000
average frequency = 5
Hence the average frequency of people hearing the spot on the radio station wkoi is calculated to be 5.

In Salt Lake City, it is 8˚ colder than it is in Houston. What's the temperature in Salt Lake City? the Houston degree is 8
The temperature in salt lake city will be 0° Celsius.
What is temperature?
Temperature tells us about the degree of hotness or coldness of a body. According to the thermodynamics, temperature is a measure of the average kinetic energy of the atoms or molecules in the system.
Given is Salt Lake City where it is 8˚ colder than it is in Houston.
The degree of coldness on Celsius scale increase as the temperature tends to negative values and degree of hotness on Celsius scale increase as the temperature tends to positive values. The temperature in Houston is 8° Celsius. Since, the temperature is 8 degrees colder, we will subtract 8° from the temperature value in Houston. Therefore, temperature in salt lake city will be -
T[S] = + 8 - 8 = 0° Celsius
Therefore, the temperature in salt lake city will be 0° Celsius.

A father and a son go hunting. The father kills an average of 2 animals every 5 shots and the son kills one animal every 2 shots. If the two fired at the same animal at the same time, what is the probability that they will obtain kill?
The probability that the father and son will obtain a kill if they both fired at an animal the same time is 0.9
What is the probability of an event?The probability of an event is the likelihood of the occurrence of event.
The average number of animals the father kills every 5 shots he takes = 2
The average number of animals the son kills every 2 shots he takes = 1
[tex]Probability = \dfrac{Number \ of \ required \ items}{Number \ of \ possible \ outcomes}[/tex]
Which gives:
The probability that the father kills an animal = [tex]P(F) = \dfrac{2}{5} = 0.4[/tex]
The probability that the son kills an animal is; [tex]P(s) = \dfrac{1}{2} =0.5[/tex]
The probability that if the father and the son fires at the same animal, the probability that they will obtain a kill, which is the probability that the animal is killed , P(A) = The probability that the father kills the animal + The probability that the son kills the animal
P(A) = P(F) + P(s) = P(F) ∪ P(s)Which gives: P(A) = 0.4 + 0.5 = 0.9
The probability that the animal will be killed is approximately 0.9

Tommy deposited $2,000 into a savings account that earns 5% interest per year. What
equation would be used to determine how much money Tommy has after x number of years?
Answer:
7A, 8D
Step-by-step explanation:
The compound interest formula is as followed
[tex]A = P(1+\frac{r}{n} )^{nt}\\[/tex]
A = accumulated amount
P = principle
r = interest rate
n = compounding
t = time
The accumulated amount is represented by f(x).
The principle is the amount of money you start with. In this case Tommy starts with 2000 dollars. P = 2000
The interest rate is 5%. This needs to be converted into a decimal.
5% = 0.05 = r
The money is compounded annually, thus n = 1.
The time is represented by x. x = t.
thus
[tex]f(x) = 2000(1+0.05)^{x}[/tex]
After six years, you simply find f(6), or substitute 6 into x.
f(6) = 2000(1.05)^6 = $2,680.19

Suppose the sequence 28, 14, ... is geometric.
a)Determine the common ratio.
b) List the next 3 terms in the sequence. Explain your reasoning.
please help me!!
Answer:
see explanation
Step-by-step explanation:
(a)
common ratio r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{14}{28}[/tex] = [tex]\frac{1}{2}[/tex] = 0.5
(b)
to find the next term, multiply the previous term by r = 0.5
14 × 0.5 = 7
7 × 0.5 = 3.5
3.5 × 0.5 = 1.75
the next 3 terms in the sequence are 7 , 3.5 , 1.75
⇒In a geometric sequence to find the common ratio(r) we use the formula
[tex]r=\frac{T_{2} }{T_{1} }[/tex]
But in general we use the formula is [tex]r=\frac{T_{n+1} }{T_{n} }[/tex]
In this case we are going to use
[tex]r=\frac{14}{28} \\r=\frac{1}{2}[/tex]
⇒The common ratio of the sequence is [tex]\frac{1}{2}[/tex], to get the 3 consecutive terms you are going to multiply the current term by the common ratio which in this case is [tex]\frac{1}{2}[/tex]
[tex]T_{3} =T_{2} * r\\\\T_{3}=14(\frac{1}{2} )\\T_{3} =7[/tex]
[tex]T_{4} =T_{3} *r\\T_{4}=7(\frac{1}{2} )\\T_{4}=\frac{7}{2}[/tex]
[tex]T_{5}=T_{4} *r\\T_{5}=\frac{7}{2} *\frac{1}{2} \\T_{5}=\frac{7}{4}[/tex]

A company prices its tornado insurance using the following assumptions:
• In any calendar year, there can be at most one tornado.
• In any calendar year, the probability of a tornado is 0.04.
• The number of tornadoes in any calendar year is independent of the number of tornados in any other calendar year.
Using the company's assumptions, calculate the probability that there are fewer than 2 tornadoes in a 14-year period.Round your answer to 4 decimals.
The correct answer is 0.4834
There can only be one tornado every year on the calendar. This indicates that there are only two conceivable outcomes of the event: either there will be one tornado or none at all.
The likelihood of a tornado in any given year is 0.14. This indicates that an event's chance of occurring is fixed. p = 0.14
The frequency of tornadoes in one year is unrelated to the quantity in other years. This indicates that the incidents are unrelated to one another.
The likelihood that there won't be more than two tornadoes in a 12-year period has to be calculated. This indicates that the number of trials, n, is set at 12.
p = 0.14
q = 1 - p = 1 - 0.14 = 0.86
n = 12
x = 2
We need to find: P( x < 2)
Fewer than 2 tornadoes means either 1 or 0 tornado. So,
P(x < 2) = P(x=0) + P(x=1)
the likelihood of less than two tornadoes occurring in a 12-year period is 0.4834
