In a multiple-choice question with four alternatives, if the null hypothesis is correct, the probability of a person choosing the correct answer is approximately

25%,

This is because there are four choices to choose from, meaning each choice has a 25% chance of being chosen at random.

Assuming there is only one correct answer, that means that there is a 25% chance of it being chosen at random.

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.

step-by-step explanation:

the given radical expression is:

we can rewrite this as:

we express as square numbers to get;

the exponents will now cancel out to give.

the correct answer is d
