Manny makes the following purchases at the store:

Anna [14]

The <em>correct answer</em> is:

He paid the correct amount.

Explanation:

First we find the subtotal of Manny's items:

32.65+3(14.89)+39.99 = 32.65+44.67+39.99 = 117.31

Next, we calculate the discount. If he gets 10% off, this means he pays 100%-10% = 90% of the total. 90% = 90/100 = 0.9:

0.9(117.31) = 105.579

Next we calculate the tax. Since tax is 8%, this means he pays 100% of his subtotal after discount plus the 8% tax; 100%+8% = 108%; 108% = 108/100 = 1.08:

1.08(105.579) = 114.02532 ≈ 114.03

Since this is what he paid, he paid the correct amount.

lidiya [134]

Answer:

a.H0: μ =530mL vs. Ha: μ > 530mL

Step-by-step explanation:

-A hypothesis test will be used to provide evidence that the median is more or equal to the stated median value.

#In a normally distributed population, the mean=mode=median:

$Mean=Mode=Median=\mu$

-The null hypothesis states that the median is equal to the stated value:

$H_o:\mu=530 \ mL$

-The alternative hypothesis provides evidence that the median value is greater than the stated value:

$H_a:\mu>530\ mL$

Hence, the correct hypotheses are H0: μ =530mL vs. Ha: μ > 530mL
