If one of the 50 states is chosen at random, then a standard die is rolled, Find the probability of getting a state that starts
Black_prince [1.1K]

Answer:

The final answer is 2/15 or 0.133

Step-by-step explanation:

The US States that start with an "N" are:

  1. Nebraska
  2. Nevada
  3. New Hampshire
  4. New Jersey
  5. New Mexico
  6. New York
  7. North Carolina
  8. North Dakota

The probability of selecting a state that starts with an N is 8/50

The probability of rolling at least a two is 5/6.

If we multiply the two probabilities together, we get 2/15.

Wally wants to determine the height of a statue that casts a 164-inch shadow by comparing it to his own height and shadow length
nataly862011 [7]

We have been given that Wally wants to determine the height of a statue that casts a 164-inch shadow by comparing it to his own height and shadow length. Wally is 68 inches tall, casts a shadow that is 41 inches in length.

We will use proportions to solve for the height of the statue because proportions state that ratio between two proportional quantities is same.

\frac{\text{Height of statue}}{\text{Shadow of statue}}=\frac{\text{Height of Wally}}{\text{Shadow of Wally}}

Upon substituting our given values in above equation, we will get:

\frac{\text{Height of statue}}{\text{164 cm}}=\frac{\text{68 inch}}{\text{41 inch}}

\frac{\text{Height of statue}}{\text{164 cm}}\times \text{164 cm}=\frac{\text{68 inch}}{\text{41 inch}}\times \text{164 cm}

\text{Height of statue}=\frac{\text{68 inch}}{1}\times 4

\text{Height of statue}=272\text{ inches}

Therefore, the height of the statue is 272 inches.
