Answer:

it's only 2pi/B because the period of sin and cos is 2pi. If we were dealing with tan it'd be pi/B, since the period of tan is just pi.

5w=5×10 to the second power

torisob [31]

Hey there!

5 x w = 10 to the second power . . .

10 x 10 = 100

5 x 100 = 500

5 x w = 500

500 = 5w

w = 100 <-------

Hope this helps you.
Have a great day!

The lengths of nails produced in a factory are normally distributed with a mean of 4.634.63 centimeters and a standard deviation

dmitriy555 [2]

The prbability that a normally distributed dataset with mean, μ, and standard deviation, σ, is between two values a and b is given by:

$P(a\ \textless \ X\ \textless \ b)=P(X\ \textless \ b)-P(X\ \textless \ a) \\ \\ =P\left(z\ \textless \ \frac{b-\mu}{\sigma} \right)-P\left(z\ \textless \ \frac{a-\mu}{\sigma} \right)$

Given that the lengths of nails produced in a factory are normally distributed with a mean of 4.63 centimeters and a standard deviation of 0.06 centimeters.

To find the two lengths that separate the top 7% and the bottom 7%, Let the two required lengths be a and b, because of the symmetry of the normal curve, the probability that the length of a randomly selected nail is between these two lengths is given by:

$P(a\ \textless \ X\ \textless \ b)=1-(0.07+0.07) \\ \\ 2P(X\ \textless \ a)-1=1-0.14 \\ \\ 2P\left(z\ \textless \ \frac{a-4.63}{0.06} \right)-1=0.86 \\ \\ 2P\left(z\ \textless \ \frac{a-4.63}{0.06} \right)=1.86 \\ \\ P\left(z\ \textless \ \frac{a-4.63}{0.06} \right)=0.93=P(z\ \textless \ 1.476) \\ \\ \frac{a-4.63}{0.06}=1.476 \\ \\ a-4.63=0.06(1.476)=0.08856 \\ \\ a=4.63+0.09=4.72 \ and \ b=4.63-0.09=4.54$

Therefore, the two lengths that separate the top 7% and the bottom 7% are 4.54 and 4.72.

A carton of paper is priced at $27.00 now. If the papergoes on sale for 25% off the current price, what will be the sale price o

Alenkinab [10]

Divide the 27 by 4 and that will give you 6.75. Subract the 6.75 from the 27 and theres your answer (20.25) so the sale price is $20.25
