Consider the following set of random variables: a. total number of points scored during a football game b. lifespan in hours of a halogen light bulb c. height in feet of the ocean's tide at a given location d. number of fatalities in civilian aircraft crashes in a given year e. length in inches of an adult rattlesnake which of these are continuous random variables?

B. Lifespan in hours of a halogen light bulb          

C. Height in feet of the ocean's tide at a given location      

E. Length in inches of an adult rattlesnake

Step-by-step explanation:

Continuous random variable.

A. Total number of points scored during a football game

Since these cannot be explained in the form of decimals, they cannot take any variable over an interval. thus, they are not continuous random variable.

B. Lifespan in hours of a halogen light bulb

This s a continuous random variable as this value is measured and can be expressed in the form of decimals.

C. Height in feet of the ocean's tide at a given location

This s a continuous random variable as this value is measured and can be expressed in the form of decimals.

D. Number of fatalities in civilian aircraft crashes in a given year

Since these cannot be explained in the form of decimals, they cannot take any variable over an interval. thus, they are not continuous random variable

E. Length in inches of an adult rattlesnake

This s a continuous random variable as this value is measured and can be expressed in the form of decimals.

the correct answer is semicircle

step-by-step explanation:

the answer is semicircle because the shorter arc joining two points on the circumference of a circle is known as the minor arc, the larger arc is called the major arc, and a semicircle is a half circle, formed by cutting a whole circle along a diameter line.
