Answer:
All trigonometric Ratios are
,
, 
And
.
Step-by-step explanation:
Given that,
A right angle triangle ΔABC, ∠C =90°.
Diagram of the given scenario shown below,
In triangle ΔABC :-

So, 

Now, for ∠A the dimensions of trigonometric ratios will be changed.
Here the base for ∠A is AC , perpendicular side is CB and hypotenuse will be same for all ratios.

Again, 
Then, 
And
.
Hence,
All trigonometric Ratios are
,
, 
And
.
25 ÷ (6 - 1) = 25 ÷ 5 = 5, she saved 5 nickels,
5 nickels = 5 × 5 = 25 cents = $0.25
5 + 25 = 30, she saved 30 dimes, 30 dimes = 300 cents = 3 dollars.
3 + 0.25 = $3.25, she saved $3.25 in all.
Answer:
73.4
Step-by-step explanation:
-Given that 75,511 out of 822,959 residents enrolled in the college, the probability of success is calculated as:

#We know that this is a binomial distribution with p=0.09176 and n=800, Expected value is calculated as:

Hence the expected value E(X)=73.4
The answer is 6 ....you just have to do the steps backwards and it will result faster.
6+5=11
11*2=22
22-6=16
16/2=8
