Given function is
At t= 79.5 degree.
So we can place t= 79.5 in given equation
=
=
=
So elevation equal to 625 meter at t = 79.5 degree.
91 is 130% of what number...
91 = 1.3x
91 / 1.3 = x
70 = x
so 91 is 130% of 70 <==
Answer:
he seventh angles measure is 103
Step-by-step explanation:
Interior angles = (number of side in the polygon - 2) times 180.
So Heptagon interior angles = (7-2)(180) = 900
To find the missing angles add all the given angles together (122, 153, 168, 105, 162, and 87) = 797.
Now The measure of the seventh angles = total angles measure - the six given angles,
The seventh angles measure is 103
900 - 797 = 103
Answer:
b
Step-by-step explanation:
a x (b + c) = (a x b) + (a x c)
Answer:
A sample size of at least 87 will be needed.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
In this problem, we have that:
So
A sample size of at least 87 will be needed.
