A student will be taking a quiz he is underprepared for and will guess every answer. The quiz consists of 10 true/false questions. Find the probability that he guesses:

i say the answer is either 1/2 because true or false or 5/10 because you have a 50/50 chance but im more on the 1/2

Step-by-step explanation:

mark  brainlest please

3/4 ÷ 3/4

step-by-step explanation:

basically divide any proper fraction with itself to fit the criteria.

so if we are using 3/4, then:

3/4 ÷ 3/4 = 1

so 1 is the quotient.

and the numerators for both these fractions is 3.   and if we divide the numerators:

3 ÷ 3 = 1

we see that quotient is equal to our original quotient as well.

reduce the friction between its moving parts

step-by-step explanation:

in fact, by reducing the friction between the moving parts of the machine, it is possible to reduce the energy wasted due to this friction; therefore, more input energy is converted into useful work, and this will improve the efficiency of the machine.
