Hey There Baby and, Welcome to Brainly
<span>Which equation has the same solution as x²- 6x - 12 = 0
</span><span> x^2 - 6x = 12 </span>
<span>
x^2 -6x + 9 = 12+9 </span>
<span>
x^2 -6x + 9 =21 </span>
<span>
(x-3)^2 = 21
</span>
So the answer will be <span>(x-3)^2=21 </span>
Answer:
16%
Step-by-step explanation:
The Empirical Rule claims that 68% of the values in a normal distribution are within 1 standard deviation of the mean, 95% are within 2 standard deviations, and 99.7% are within 3. Using this here, we can see that 102 is exactly 1 standard deviation from the mean, as 94 + 8 * 1 = 102.
We also know that a normal distribution is symmetric, meaning that there is an equal distribution on both sides of the mean. Therefore, we can say that 50% of the values are above the mean. Next, 68% of values are within 1 standard deviation of the mean, so here, we can say that 34% of values are between the mean and 1 positive standard deviation of the mean. We want to find how many values are greater than 1 standard deviation of the mean. This is equal to (total amount of values greater than the mean) - (total amount of values greater than the mean but not greater than 1 standard deviation of the mean) = 50% - 34% = 16%

25-7.5=17.5
So the original price of Harry's three T-shirts will be $17.50
