Suppose a large shipment of telephones contained 21% defectives. If a sample of size 498 is selected, what is the probability th
grandymaker [24]

Answer:

P(-3\% < x < 3\%) = 0.901

Step-by-step explanation:

Given

p = 21\%

n = 498

Required

P(-3\% < x < 3\%)

First, we calculate the z score

z = \sqrt{p * (1 - p)/n}

z = \sqrt{21\% * (1 - 21\%)/498}

z = \sqrt{21\% * (79\%)/498}

z = \sqrt{0.1659/498}

z = \sqrt{0.000333}

z = 0.0182

So:

P(-3\% < x < 3\%) = P(-3\%/0.0182 < z

P(-3\% < x < 3\%) = P(1.648 < z

From z probability, we have:

P(-3\% < x < 3\%) = 0.901

The world’s largest round pizza was set in December 2012 by five Italian chefs. The diameter of this pizza was 131 feet. If this
Tems11 [23]

First find the area of the whole pizza.

The formula for area of a circle is Area = PI x r^2

The diameter is given as 131 feet, so r would be 131/2 = 65.5 feet.

I will use 3.14 for PI since the problem doesn't say what value to use.


Area = PI x 65.5^2

Area = 3.14 x 4290.25

Area = 13,471.39 square feet


Divide the total area by the number of pieces:

13,471.39 / 50 = 269.43 square feet


To find the length of the crust first find the circumference of the whole pizza:

Circumference = PI x diameter

Circumference = 3.14 x 131 = 411.34 feet

Now divide the total by the number of pieces:

411.34 / 50 = 8.23 feet


Each slice has an area of about 269.43 square feet and a crust length of 8.23 feet.

Can someone how to get the answer? Thanks! PLEASE HELPpppppppppppppppppppppppp

\mathrm{If\:}f\left(x\right)=g\left(x\right)\mathrm{,\:then\:}\ln \left(f\left(x\right)\right)=\ln \left(g\left(x\right)\right) \ \textgreater \  \ln \left(6^x\right)=\ln \left(21\right)

\mathrm{Apply\:log\:rule}:\ \log _a\left(x^b\right)=b\cdot \log _a\left(x\right) \ \textgreater \  \ln \left(6^x\right)=x\ln \left(6\right)

x\ln \left(6\right)=\ln \left(21\right) \ \textgreater \  \mathrm{Divide\:both\:sides\:by\:}\ln \left(6\right) \ \textgreater \  \frac{x\ln \left(6\right)}{\ln \left(6\right)}=\frac{\ln \left(21\right)}{\ln \left(6\right)}

Therefore \: x=\frac{\ln \left(21\right)}{\ln \left(6\right)}

In your case ln means \frac{log 21}{log 6}
