Normal Distribution
MariettaO [177]

Answer:

No

Step-by-step explanation:

<u>Explanation</u>:-

  • The graph of the normal distribution y = f(x) in the x y- plane is known as normal curve.The curve is bell shaped and symmetrical about the line x = μ

        So The first statement is not true because symmetrical about the line        x = μ not 'm'

  • Area under normal curve represents the total population

so the total area under the curve is 100 or one so  The second statement is true

  • The normal distribution for mean is zero and standard deviation is one is known as standard normal distribution.
  • 95 percentage within two standard deviations
  • 99.7 percentage of the data are within three standard deviations of the mean.
  • 68 percentage of the data are within one standard deviation

All above points are true so In given data the third statement is not true

95 percentage within two standard deviations not one

  • The fourth statement is false because 68 percentage of the data are within one standard deviation not 34 percentage.
  • All data sets are normally distributed its depend on given data

A retailer buys a coat in bulk at a unit price of $45. The coat is marked up to 28% to sell in the store. What is the price of t
Lostsunrise [7]

Answer:

57.60

Step-by-step explanation:

If the coat is marked up 28%, then the cost is increased by 28% to produce the selling price.

SP = 45 + 28/100 * 45

SP = Selling Price

SP = 45 + 28*45 / 100

SP = 45 + 1260 / 100

SP = 45 + 12.60

SP = 57.60

Answer: The selling price is 57.60

Been a while since I’ve needed to not use a calculator. Why is -2X10^-18 (3/16) = 4.09X10^-19?
Anestetic [448]

Answer:

see the explanation

Step-by-step explanation:

we have

2.18*10^{-18}(\frac{3}{16})

we have that

\frac{3}{16}=0.1875

Convert to scientific notation

0.1875=1.875*10^{-1}

substitute

2.18*10^{-18}(1.875*10^{-1}})

Remember that

To multiply two numbers in scientific notation, multiply their coefficients and add their exponents

2.18*10^{-18}1.875*10^{-1}}=(2.18*1.875)*10^{(-18-1)}=4.0875*10^{-19}

Round the number 4.0875 two decimal places

so

4.0875*10^{-19}=4.09*10^{-19}
