Hi there!

If Andrea bought 12 bagels and 2/3 were multigrain we can determine what the total amount of bagels that are multigrain by finding a common denominator. We can do this by multiplying 2/3 * 4 which gets us the common denominator we need.

2/3 * 4 <--- Equation
8/12 <--- Simplified from step 1.

Therefore 8 out of the 12 bagels Andrea bought were multigrain!

Answer: $32,625

Step-by-step explanation:

40,000-10,000 = 35,000 ---> how much is taxed

35,000 x .25 = 8,750 = income tax

45,000 - 8,750 = 36,250

36,250 x .1 = 3,625 ---> social security

45,000 (gross pay) - 8,750 (income tax) - 3,625 = 32, 625

Answer:

0.6568 = 65.68% probability that she would be correct.

Step-by-step explanation:

When the distribution is normal, we use the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

45000, 45500, 44500, 46000 and 44000 units. This rate of sales is considered average for the product over the last twenty years or so.

This means that:

$\mu = \frac{45000 + 45500 + 44500 + 46000 + 44000}{5} = 45000$
