Answer:
Sample data - subset of the total population from which estimates about the population can be made
Point estimate - an estimate that is a single number which is represented as a point on a line
Interval estimate - a range of values within which a true mean will fall
Hope this is correct :)
Answer:
The period is of 
units.
The horizontal shift is of 30 units to the left.
Step-by-step explanation:
The secant function has the following general format:
A represents the vertical shift.
C represents the horizontal shift. If C is positive, the shift is to the right. If it is negative, it is to the left.
The period is 
In this question:
So 
Then 
The period is of units.
The horizontal shift is of 30 units to the left.
Answer:
B. 57°F
Step-by-step explanation:
Given:
F = n/4 + 37
Where,
F = temperature in degrees Fahrenheit
n = number of times per minute crickets chirps
Find F when n = 80
F = n/4 + 37
F = 80/4 + 37
= 20 + 37
= 57
F = 57 °F
B. 57 °F
Answer:
x = 10.7775
Step-by-step explanation:
We can see that we need to use sin∅ to help solve for <em>x</em>:
sin56° = x/13
13sin56° = x
x = 10.7775
