To find the probability that she develops lung cancer given that she smokes, multiply the two probabilities together:
4/9 x 3/10 = (4 * 3) / (9*10) = 12/90 = 2/15
That's not a good question at all. It's a lot like asking
"What are the statements for News and President Obama ?"
There are at least a hundred formulas that are useful in trigonometry.
One of the most useful is:
In a right triangle, the square of the length of the hypotenuse
is equal to the sum of the squares of the two short sides.
Pythagoras is the name of the ancient Greek mathematician who
discovered that formula. The formula is so useful that it's known
by his name, in his honor.
C(12/15) because the other 3 all equal 0.666666666666667 but 12/15 equals 0.8
Hi There!
--------------------------------------------
Remember to follow PEMDAS.
--------------------------------------------
Problem #1:
= (25 - 6.25) + (5 · 3)²
= (18.75) + (15)²
= 18.75 + 225
= 243.75
--------------------------------------------
Problem #2:
= (8 + 3)² + 10 · (-4)
= (11²) + 10 · (-4)
= 121 + 10 · (-4)
= 121 + (-40)
= 81
--------------------------------------------
Hope This Helps :)
