Eitan randomly selected volcanoes to travel to and study. After traveling, he had seen 13 cinder cone volcanoes, 18 shield volca

noes, and 6 stratovolcanoes. Use the observed frequencies to create a probability model for Eitan randomly selecting one volcano in the world on which to conduct an extensive study.

Answer:

Probability of selecting one volcano in the world on which to conduct an extensive study is given by

\frac{1}{37}

Step-by-step explanation:

Since we have given that

Number of cinder cone volcanoes = 13

Number of shield volcanoes = 18

Number of strato volcanoes = 6

Total number of volcanoes is given by

13+18+6\\\\=37

So, Probability of getting one volcano in the world on which to conduct an extensive study is given by

\frac{\text{Number of favorable outcomes}}{\text{ Total number of outcomes}}\\\\=\frac{1}{37}

Hence, Probability of selecting one volcano in the world on which to conduct an extensive study is given by

\frac{1}{37}

Answer:

P( cinder cones ) =  13/37

P ( shield ) =  18/37

P ( stratovolcanoes) =  6/37

Step-by-step explanation:

We need to find the total number of volcanoes

13 +18 + 6 = 37

P( cinder cones ) = number of cinder cones/ total = 13/37

P ( shield ) = number of shield /total = 18/37

P ( stratovolcanoes) = number of strato /total = 6/37

Answer: Choice C) Multiplication property of inequality

The rule basically says that if you start with a < b and you multiply both sides by some positive number c, then a*c < b*c. The sign doesn't flip if you multiply both sides by a positive number.
The sign will flip if c is negative. So we'll go from a < b to a*c > b*c if c is negative.

Example 1:
1 < 5
-2 > -10 ... multiplied both sides by -2; sign flips

Example 2: 
3 < 7
9 < 21 ... multiplied both sides by 3; sign does not flip

Similar rules apply to a > b, a \le b and a \ge b
