Answer:
The required probability is 0.3717.
Step-by-step explanation:
Consider the provided information.
There are approximately 100 species of venomous snakes, but only about 12 have a deadly bite.
zoo randomly selects one snake from each of five different species to show visitors.
The total number of ways to select 5 different species out of 100 are:
We need to find the probability that exactly one of the five snakes shown is deadly.
That means out of 12 deadly bite we need to select only 1.
Thus, the number of ways are:
Hence, the required probability is:
The required probability is 0.3717.
33% of 15 is 5. If 5 = 33%, that means that x/3=5. so multiply both sides by 3 to get x=15.
It is asking what number can you take 33% of and get 5? So you are not dividing 5 by 3, you are multiplying it by 3
Answer:
first one: B and C
Second one: x=12, y=10 so the answer is B.
Step-by-step explanation:
First one: Irrational numbers are any numbers that go on forever in the decimal without ever repeating. Any square roots of numbers that aren't perfectly square, such as 4 and 9, are irrational. And anything with pi, or 
, is always irrational.
Second one: 144 and 100 are perfect squares, meaning it can be created by multiplying the same number by itself, in this case 12 and 10. Subtract those and you get 2.
1) 180 square cm
Answer:
2) 41 cubic cm
Step-by-step explanation:
1)
Area of pool = 12 * 15 = 180 square cm
2) Volume of water = 1/3 * Volume of pool
= 1/3 *123
= 41 cubic cm
Answer:
a=2
b=10.5
c=4
d=17.5
Step-by-step explanation:
so 3.5 miles per hour and the columns are miles and then hours
so an equation can be 3.5 (mi/hr) * t (time) = distance
so for a): 3.5*t=7
t=2
b) 3.5*3=distance
distance is 10.5
c) 3.5*t=14
t=4
d) 3.5*5=d
d= 17.5
