Suppose the expression a(b)n models the approximate number of people who visited an aquarium each day since an aquarium opened, where a is the initial number of people who visited, b is the rate of increase in the number of people who visited each day, and n is the number of days since the aquarium opened.
If the expression below models the number of visitors to a particular aquarium, what is the correct interpretation of the second factor?
Answers
Answer: I worked it out and got D but I'm not 100% sure.
The correct option is option B: There were 6.27 times as many people who visited the aquarium on the 7th as on the first day.
What is exponential function?The function which involves an exponent with a base so that the base is rises exponent times is called exponential function.
for example is f(x)=bˣ where b is base and x is exponent
Here it is given that
the following exponential equation:
y = A(b)ⁿ
where the following variables is defined as :
A: the initial number of customers applied
b: the rate of increase of the number of people applied every month
n: the number of months from the bank opened
Substituting values in the above exponential expression we have:
y = 64(1.3)⁷
y = 64*6.27
Therefore There were 6.27 times as many people who visited the aquarium on the 7th as on the first day.

The equation y = 14x/z represents _____________ variation.
A.
inverse
B.
direct
C.
combined
D.
joint
Answers
Answer:
D. joint variation
Step-by-step explanation:
y = 14x/z
y is directly proportional to x and inversely proportional to y
Constant of proportionality = 14
Direct variation is given as
y = kx
Where, k = constant of proportionality
Inverse variation is given as
y = k/z
Where, k = constant of proportionality
When they are jointly combined
y = kx/z

is most liked. He is trying to decide who to survey.
Which population sample does NOT produce a biased result?
A. He asks the school’s teachers
B. He asks his friends after school
C. He asks the students in his math class
D. He asks students he meets in the hallways
E. He asks every fifth student arriving at school
Answers
Answer: E is the answer
Step-by-step explanation:
The population sample that does not produce a biased result is when he asks every fifth student arriving at school. The correct option is E.
What is a survey?Surveys can be used to determine how representative each person's opinions and experiences are.
When conducted properly, surveys offer precise data about people's beliefs and actions that can be utilized to inform significant decisions.
A huge population's characteristics can be described through surveys. No other research methodology can offer such a wide range of capabilities.
This guarantees a more accurate sample to collect focused results from which to draw conclusions and make significant judgments.
Survey bias is when a question is worded or presented in a way that encourages individuals to select one response over another.
The same holds true if your queries are challenging for customers to comprehend and honestly answer.
As, when he asks every fifth student arriving at school, it can lead to an unbiased result.
Thus, the correct option is E.

How many blue pens were there to start with?
Answers
Answer:
180 blue 70 red
Step-by-step explanation:
b= blue r = red
b+r = 250
r = (250-b)
If 40% is removed the rest is 60%
If the 70% is removed the rest is 30%
0.6b + 0.3(250-b) = 129
0.6b + 75 - 0.3b = 129
0.3b = 54
divide by 0.3
b = 180
250-180 = 70
60% 0f 180 = 108
30% of 70 = 21

C. 1/7

Answer:
C correct answer is c o think do
The probability that the object is green or a cube will be 9/14. Thus, the correct option is D.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
A jar contains 2 blue cubes, 5 blue spheres, 2 green cubes, and 5 green spheres.
The total event is calculated as,
Total = 2 + 5 + 2 + 5
Total = 14
The probability that the object is green or a cube is calculated as,
P = 7 / 14 + 4 / 14 - 2 / 14
P = 1/2 + 2/7 - 1/7
P = 9/14
Thus, the correct option is D.
