3/4 is equal to 75%, or if you were going by .25=1/4 than it would be .75
If the legs of a right triangle are a and b and the hypotnuse is c then
a²+b²=c²
so we are given
the legs are x and √7
and the hypotnuse is √19
so
x²+(√7)²=(√19)²
x²+7=19
minus 7 both sides
x²=12
sqrt both sides
x=√12
x=√(4*3)
x=(√4)(√3)
x=2√3
Answer:
400 times more likely.
Step-by-step explanation:
Converting the percents to fractions
20% = 20/100 = 0.2
0.05% = 0.05/100 = 0.0005
So required likely hood = 0.2 / 0.0005
= 400.
5 is 1/40 of 200.
Therefore, 35 is 7/40 of 200.
7/40 = (17.5)/100. Therefore, 35 is 17.5% of 200.
----------------------------------------
To make life easier. Just say that 35/200 =17.5/100.
So 35 is 17.5% of 200.
