Answer:
As functions of a true variable, exponential functions are uniquely characterized by the very fact that the expansion rate of such a function (that is, its derivative) is directly proportional to the value of the function.

Have a nice day hope this helps.
Answer:
8.2+/-0.25
= ( 7.95, 8.45) years
the 95% confidence interval (a,b) = (7.95, 8.45) years
Step-by-step explanation:
Confidence interval can be defined as a range of values so defined that there is a specified probability that the value of a parameter lies within it.
The confidence interval of a statistical data can be written as.
x+/-zr/√n
Given that;
Mean x = 8.2 years
Standard deviation r = 1.1 years
Number of samples n = 75
Confidence interval = 95%
z value(at 95% confidence) = 1.96
Substituting the values we have;
8.2+/-1.96(1.1/√75)
8.2+/-1.96(0.127017059221)
8.2+/-0.248953436074
8.2+/-0.25
= ( 7.95, 8.45)
Therefore the 95% confidence interval (a,b) = (7.95, 8.45) years
Answer:
Step-by-step explanation
you are able to make two squares because you can use the square root of 36 and that twill give you 6 not a decimal.
in comparison if you do the square root of 15 it will give you 3.87298335

Answer: 16 1/2
Step-by-step explanation:
It's easiest to multiply improper fractions and then to convert them back into mixed numbers, so 4 1/2 would become 9/2 and 3 2/3 would become 11/3.
= 99/6. Now just simplify to 33/2 and then convert back into a mixed number. 16 1/2
