What is the logarithmic function of the graph? show work

Mathematics
1 answer:
tatiyna1 year ago
6 0

If the function of the logarithmic graph is written as

y=\log _ax^b

Since the graph has been shifted to the right from the origin by 5 units

Then

y=b\log _a(x-5)

a is base, b is coefficient, y and x are coordinates on the line

Taking a point on the line, say (21, 2)

x= 21 and y = 2

\begin{gathered} y=\text{ }\log _a(x-5)^b \\ 2\text{ = }\log _a(21-5)^b \\ a^2=(16)^b \\ (a^2)^1=(4^2)^b \\ \text{Equating the base and the power} \\ a\text{ = 4 and b= 1} \end{gathered}

If the base is 4 and the coefficient is 1

The logarithmic function of the graph is

y=\text{ }\log _4(x-5)

6. Describe how we could conduct a simulation to decide whether a simple random sample from this population could produce a samp
BigorU [14]

Step-by-step explanation:

We have proportion p = 50/100 = 0.50

Probability of success = 1-0.50 = 0.50

To conduct simulation, let's assume experiment is to be done 10 times

1. Use binomial parameters n, number = 10, p = 0.50. we then get the necessary size of population To carry out the sampling.

2. We get a random sample and get the size of people who support an against smoking with kids in the car.

3. We repeat this process after drawing sample and also get the number of those in support of ban.

4. After getting n, we find proportion.
