Let's go shape by shape!

The area of a rectangle can be calculated as follows:

$L * W = area$ where L = length and W = width

The area of a trapezoid can be calculated as follows:

$\frac{( b_{1} + b_{2})*H}{2} = area$
where b1 and b2 = lengths of the base and H = height of the shape

The area of a parallelogram can be calculated as follows:

$B * H = area$ where B = length of the base and H = height of the shape

A $500 television is on sale for 20% off. However, you must pay 6% in sales tax. What is the final price of the television after

GrogVix [38]

20% off means you are paying 80% of the original price ( 100% - 20% = 80%)

Multiply the price of the tv by 80% to find the sale price:

500 x 0.80 = 400

Now multiply the sales price by 1 plus the tax rate to find final cost:

400 x 1.06 = 424

Final price including tax is $424

Answer:

$Z = 1$

Step-by-step explanation:

Z - score

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:

$\mu = 61, \sigma = 4$
