Answer:
Median =17
Step-by-step explanation:
Given that the mean height of an adult giraffe is 17 feet. Suppose that the distribution is normally distributed with standard deviation 0.9 feet.
Let X be the height of a randomly selected adult giraffe.
X is a random variable.
a) X is N(17, 0.9)
b) Median giraffe height = 17 ft since in normal distribution mean = median
c) When x = 18.5, Z = 
d) 
e) 
f) 75th percentile for z is 0.675
Answer: Hello welcome to brainly btw, But it say d dollars dome imaa just help you with one expression cause 8 times 3 months equls 24 dollars for 3 months
Step-by-step explanation:
Here's the sum rule for the tangent function:
In the special case a=b, this becomes the double angle formula:
In your case, you case use the sum rule once:
And use it again, in the special case of the double angle:
We can obvisouly simplify this expression a lot: let's deal with the numerator and denominator separately: the numerator is
and the denominator is
So, the fraction is
Use Pythagoras theorem：
It can be used in any right triangle
