Step-by-step explanation:
so we're making two draws *with* replacement (this is important)
step 1: for the first draw, it wants the probability of getting a sour candy. to calculate this:
(# of sour candy) / (total # of candy)
step 2: for the second draw, it wants the probability of *not* getting a sour candy. to calculate this, you can calculate 1 - (the probability form part 1).
step 3: to find the probability of both events happening together, simply multiply the probabilities from part 1 and 2 together
side note: for step 2, you can only do this because the candy is being replaced. if there were no replacement, you'd have to re-calculate (# of non-sour candies) / (total after the first candy is drawn)
Answer:
A
Step-by-step explanation:
The side lengths must satisfy the Pythagorean Theorem to be a right triangle. The formula is
where a is the smallest side, b is the medium side, and c is the largest side. Test each set of numbers.

This satisfies the theorem. Since this is a multiple choice question, only one solution is possible. A is the solution.

Answer:
31%
Step-by-step explanation:
3/10 is the same as 30%
If 30% of the students liked English and 61% of the students like math, the difference can be found by using subtraction.
61% - 30% = 31%
C is right. She has partially completed the construction. Her next step is to use the arc markings to determine the radius to construct the circle.
