Eunice lives in indiana, which has a sales tax of 7%. She just bought a couch whose full price was $1200 but she got 20% off bc

Tcecarenko [31]

Answer:

Total amount paid by Eunice=$1,044

Step-by-step explanation:

Step 1: Determine full price of couch

Full price of couch=$1200

Step 2: Determine tax

Tax=tax rate×full price

where;

tax rate=7%

full price=$1200

replacing;

Tax=(7/100)×1,200=$84

Tax=$84

Step 3: Calculate the sale price

Sale price=Full price-20% discount

where;

Full price=$1,200

discount=(20/100)×1,200=$240

replacing;

Sale price=(1,200-240)=960

Sale price=$960

Step 4: Total amount paid by Eunice

Total amount paid by Eunice=Sale price+tax

where;

Sale price=$960

tax=$84

replacing;

Total amount paid by Eunice=(960+84)=$1,044

Total amount paid by Eunice=$1,044

A worn, poorly set-up machine is observed to produce components whose length X follows a normal distribution with mean 14 centim

Akimi4 [234]

Answer:

74.86% probability that a component is at least 12 centimeters long.

Step-by-step explanation:

Problems of normally distributed samples are solved using 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.

In this problem, we have that:

$\mu = 14$
