Suppose that an instructor assigns different letter grades based on points earned on a 10-point quiz, and that all scores have been verified to be between 0 and 10 inclusive. also suppose that four possible letter grades can be assigned and that 9 or 10 points is an a, 7 or 8 points is a b, 6 points is a c, and 5 or fewer points is an f. to assign letter grades, the most efficient numeric array containing point values would contain elements. a. tenb. fivec. fourd. three

three

Explanation:

Since there are four grades to be represented, any three letter grades can correspond, with a one-to-one mapping, to the elements in the numeric array. Any point that is not represented can be given to the fourth letter grade.

This is also possible because it has been verified that all scores are between 0 and 10. Not more.

Hope this helps!

the answer to your question would be something called hertz. the unit of measurement called a hertz, which is one cycle per second, is used to measure clock speed. within one cycle, your computer processes, refreshes, or updates itself to the changes that it is going through. in the case of computer clock speed, one hertz equals one tick per second. the clock speed of computers is usually measured in megahertz (mhz) or gigahertz (ghz)
