The correct answer is B. Most patients who have a poor dental experience also have post-extraction complications. This can be shown through the fact that of everyone who had a poor dental experience, 94% said they had post-extraction complication. 94% is obviously <em>most</em>. We can not confidently say that poor dental experiences cause post-extraction problems because we do not know how many people who had a normal or good experience also had problems.
Ok so first off understand what they are saying. there is a movie on sale for $22.10 which is 15 percent of the original price. So now what you do is set up the problem.
22.10 is = 15% of the price
x = 100% of the price (original price)
<u> 15 </u> = <u>22.10
</u>100 x
<u>
</u>now just use cross multiplication.
15x = 22.10 · 100
solve for x.
<u>15x</u> = <u>2210</u>
<u /> 15 15
x = 147.33333333 since the 3's go on forever you can simply put it into a fraction
x = 147 <u>3
</u> 9
<u>
</u>whenever there is a repeating number you can put it into a fraction but putting the repeating number over a 9
Answer: I am also not knowing this answer I am confused about the question.
Step-by-step explanation:
I'm assuming this is what that looks like
. We need to work inside those brackets first since the base is the same on both those expressions. The base is a 3. When we multiply like bases the rule is that we add the exponents, so what we have after that is
. Now the rule is power to power. Multiply them.
is your answer if you leave the exponent as a negative,
if you need it positive.
