I believe the answer would be D, 2y+6/9y-7 x 3/2 because dividing by a fraction is the same as multiplying by its reciprocal (the fraction flipped).
Hope I helped! ;)
X^3+x and x=2
=(2)^3+2
=8+2
=10
Answer:
The answer to the given problem is provided below.
Step-by-step explanation:
She can make the conclusion at 95% confidence level that average sales have increased:
Since the sample mean, $2,984, falls outside the range of likely sample means (which has an upper bound=$2,843.44), the store owner can reject the null hypothesis that μ≤ $2,700 μ≤ $2,700 at a 95% confidence level.
Since she can reject the null hypothesis, she can essentially accept the alternative hypothesis and conclude the average daily sales have increased.
