25 points is the same integer
The answer is 75%. This is because the 'or' rule for probability, the one we use when trying to determine P(A) or P(B), is to add the two probabilities. This means that we just need to add 30% and 45%, which gives us 75%.
I hope this helps!

Step-by-step explanation:
Using the tangent ratio in the right triangle
tan A = 
= 
= 
, then
∠ A = 
( ) ≈ 41° ( to the nearest degree )
The sum of the angles in the triangle = 180° , then
∠ B + 41° + 90° = 180°
∠ B + 131° = 180° ( subtract 131° from both sides )
∠ B = 49°
Using Pythagoras' identity in the right triangle
AB² = BC² + AC² = 7² + 8² = 49 + 64 = 113 ( take square root of both sides )
AB = 
≈ 10.6 ( to the nearest tenth )
Calculate 16% of 850.
The way I do this is by breaking it up into smaller pieces.
First I would find 10% of 850. To do this I need to divide 850 by 10, as 100%/10 gives us 10%, which is what we need.
So 10% = 85
Then we need 5%, which is half of 10%, therefore half of 85,
So 5% = 42.5
Then we need 1% which is 10%/10, so 85/10.
So 1% = 8.5
Then we add all these together to get 16%.
So 16% = 136
They predict that 102 people will come back, which is less than the 16% that should come back to stay again, so their prediction is too low.
Step-by-step explanation:
Ok, so, to find this, remember- to find the true price of an item, remember the equation (PRICE DIVIDED BY QUANTITY), this will give you true price. So, for the individual, its $3.99 for one pound. In bulk, to find the true price, do price divided by quantity. $17.45/5= 3.45. So thats the better deal. Anyways, to find out how much cheaper it is, subtract 3.45 from 3.99. The answer is .54, however, since you need to round to the nearest tenth place, the answer would be .50
