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

Fill in the missing parts. Then determine which bowl contains more sodium.
san4es73 [151]

Answer:

Soup B

Step-by-step explanation:

Given :

Soup A:

Sodium(mg) 720

Ounces 6 1

Soup B :

Sodium(mg) 600

Ounces 4 1

To Obtian the amount of sodium per ounce in each of soup A and B

Soup A :

Sodium per ounce = 720 mg / 61 = 11.803 mg / ounce

Soup B:

Sodium per ounce = 600 mg / 41 = 14.634mg / ounce

Hence. SOUP B contains more soudiun per ounce

LMN≅PQR
tresset_1 [31]
<span>LMN≅PQR means that point L is equal to P, point M is equal to Q, and point N is equal to R. All lines are the same.

Point Q has an angle of 72, which means that point M also has an angle of 72.

Now you have two angles to find x. All interior angles of a triangle add up to 180, so you can set up the following equation to find x:

72 + 36 + x = 180

Subtract 36 from both sides.

72 + x = 144

Subtract 72 from both sides.

x = 72

The angle of point L, x, is 72.

LenaWriter [7]
Make two equations. Then solve. Let t and b represent the numbers of pages in the Tax Code and Bible, respectively.
  t - b = 18,528 . . . . . tax code exceeds Bible by 18,528 pages
  t + b = 21,472 . . . . .together, they total 21,472 pages

Add the two equations.
  2t = 40,000
  t = 20,000

The number of pages in the tax code is 20,000.
