The base of the exponential function is 3.
<h3>How to identify the base?</h3>
Here we have the graph of an exponential function of the form:
f(x) = b^x
We want to find the value of b.
Remember that any number with an exponent of 1 is equal to the number:
a^1 = a
Then, we will have:
f(1) = b^1 = b
If you look at the graph, you can see that when x = 1, the function is equal to 3.
Then:
f(1) = 3 = b
From this, we can conclude that the base is equal to 3.

The sample size is n = 25
The sample mean is
Generally
The null hypothesis is : That the mean of the Arsenic blood concentrations in healthy individuals is
i.e
The null hypothesis
The alternative hypothesis is : That the mean of the Arsenic blood concentrations in healthy individuals is greater than
The alternative hypothesis
Answer: 207 over 16 or in decimal form 12.9375
Step by step explanation:
Add 15 and 3 to get 18
9+ 7x18 over 32
Multiply the 7 and 18 to get 126
9+ 126 over 32
Reduce the fraction 126 over 32 to get the lowest terms by extracting and cancelling out the 2
9+ 63 over16
Convert 9 into the fraction 144 over 16
144over16 +63over16
Both of the fractions have the same denominator, therefore you should add them by using their numerators.
144+16over16
Add 144 and 63 to get the final number.
207over16

Answer:
12.48
Step-by-step explanation:
Judging by the answers, the meaning of S4 is the sum of the first 4 terms of the series. That would be
10 + 2 + .4 + .08 = 12.48
5.1 = m/0.3
1.53 = m
Hope this helps!
