Select the correct answer. a number is selected at random from the set {2, 3, 4, 10}. which event, by definition, covers the entire sample space of this experiment? a. the number is greater than 2. b. the number is not divisible by 5. c. the number is even or less than 12. d. the number is neither prime nor composite. e. the square root of the number is less than 3.

C. The number is even or less than 12

Explanation:

Number 2 can be selected randomly and According to option A the number selected should be greater than 2.

B option is saying that the number is not divisible by 5 but the sample set contains { 2,3,4,5,6,7,8,9,10} . 5 and 10 can be selected and they are divisible by 5.

According to C even number can be selected or the numbers that are lesser than 12. The word "or" should be note here . Any number even or odd may be selected but it will be lesser than 12 so this will be the correct option.  

Every element of sample set is either prime or composite so the selected number can either be prime or composite

Square root of 9 is 3 and square root of 10 is greater than 3. Statement will not be correct if number 9 or number 10 got selected the

C. The number is even or less than 12. (for plato users.)

Explanation:

I took the test trust me.

a maximum–minimum thermometer. the scales are fahrenheit on the inside of the u and celsius on the outside. the current temperature is 23 degrees celsius, the maximum recorded is 25, and the minimum is 15, both read from the base of the small markers in each arm of the u tube. the bulbs are hidden by a plastic housing.

six's thermometer is a registering thermometer which can record the maximum and minimum temperatures reached over a period of time, for example 24 hours. it is used to record the extremes of temperature at a location, for instance in meteorology and horticulture. it was invented by a british scientist james six, born in canterbury, in 1780; [1] the same basic design remains in use.

it is also commonly known as a maximum–minimum, minimum–maximum, maxima–minima or minima–maxima thermometer, of which it is the earliest practical design.

the thermometer indicates the current temperature, and the highest and lowest temperatures since last reset.
