Answer:
7
Step-by-step explanation:
We see that are angles are both the same so perhaps the lengths are aswell.
Answer:
12 servings
Step-by-step explanation:
Given:
Evil bunny's carrot soup calls for 5/8 cups of chopped carrots per serving.
If evil bunny has chopped 7 1/2 cups of chopped carrots.
Question asked:
How many servings of carrot soup can he make?
Solution:
<u><em>By unitary method:</em></u>
cups of chopped carrots used for = 1 serving of carrot soup
1 cup of chopped carrots used for =
=
servings
cups of chopped carrots used for = 
Thus, 12 servings of carrot soup could be made.
B ) sin² x = 1 - cos² x
sin² x + cos² x = 1 ( correct )
D ) cot² x = csc² x - 1
cos²x / sin²x = 1/sin²x - 1 = (1-sin²x) / sin²x = cos²x/sin²x
Identities are B ) and D).
Answer: Population density the United Kingdom 
A= 2.63
B= 2
Step-by-step explanation:
We know that, to calculate the population density, we will divide the population by the size of the area.
i.e. 
Given : Area of UK = 243,610 km²1
Population = 
Then, the population density the United Kingdom would be :

On comparing to
, we get
A= 2.63
B= 2
Using the z-distribution, it is found that a sample of 171 should be selected.
<h3>What is a z-distribution confidence interval?</h3>
The confidence interval is:

The margin of error is:

In which:
is the sample mean.
is the standard deviation for the population.
For this problem, the parameters are:

Hence we solve for n to find the needed sample size.





n = 170.7.
Rounding up, a sample of 171 should be selected.
