A pair of shoes costs $52.99 and the state sales tax is 8%. Use the formula C = p + rp to find the total cost of the shoes, wher
Readme [11.4K]

The pair of shoes costs $52.99, so p = 52.99.

The state sales tax is 8%, which can be changed to decimal form by dividing by 100: 8/100 = 0.08. So r = 0.08.

Now you can plug both of these values into the formula to find the total cost of the shoes (c):

 

c = p + r*p

c = 52.99 + (0.08)*(52.99)

c = 52.99 + 4.2392

c = 57.2292

So the total cost of the shoes is $57.23

Alex777 [14]

Answer:

P(1739

(Correct to 4 decimal places)

Step-by-step explanation:

The probability of a continuous normal variable X found in a particular interval [a, b] is the area under the curve bounded by x=a and x=b and is given by:

P(a

where

f(X)=\frac{1}{\sigma \sqrt{2 \pi} }e^{-\frac{1}{2} (\frac{x-u}{ \sigma} )^2}



f(X)=\frac{1}{200 \sqrt{2 \pi} }e^{-\frac{1}{2} (\frac{x-1400}{ 200} )^2}\\=\frac{1}{200 \sqrt{2 \pi} }e^{- \frac{(x-1400)^2}{ 80000}\\

P(1739

P(1739

Using a calculator,

P(1739
