Y=12
x=6
The triangle is a 30-60-90 triangle!
Answer:
61 + 4x = y
Step-by-step explanation:
61 : starting tree height
4x : 4 times however many months pass
y : total height after x months.
Answer:
The 95% confidence interval for the percent of all coffee drinkers who would say they are addicted to coffee is between 21% and 31%.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence level of
, we have the following confidence interval of proportions.

In which
z is the zscore that has a pvalue of
.
The margin of error is:

A confidence interval has two bounds, the lower and the upper
Lower bound:

Upper bound:

In this problem, we have that:

Lower bound:

Upper bound:

The 95% confidence interval for the percent of all coffee drinkers who would say they are addicted to coffee is between 21% and 31%.
(22 x sin(65))/sin(53) =24.96604654 rounded of to nearest tenth = 25
So X = 25
F(x) = g(x) for x = 1 and x = 3. Verify that for yourself.
