An article was marked #80.00 During clearance sales a costumer paid #60.00 for it. What was the discount percentage

Alik [6]

Subtract to find the amount of the discount:

80.00 - 60.00 = 20.00

Divide the amount of discount by original price:

20.00 / 80.00 = 0.25

Multiply by 100 to get percent:

0.25 x 100 = 25%

Answer: 25%

The random variable K has a geometric distribution with mean 16. Which of the following is closest to the standard deviation of

sdas [7]

Answer: d. 15.49

Step-by-step explanation:

Given : The random variable K has a geometric distribution with mean 16.

Formula for Mean and standard deviation in geometric distribution:

$\mu=\dfrac{1}{p}$ (1)

$\sigma=\dfrac{\sqrt{1-p}}{p}$ (2), where p is the probability of success in each trial.

Since $\mu=16$ (Given)

Then from (1) ,

$\dfrac{1}{p}=16\\\Rightarrow\ p=\dfrac{1}{16}=0.0625$

Put value of p in (2),

$\sigma=\dfrac{\sqrt{1-0.0625}}{0.0625}=\dfrac{\sqrt{0.9375}}{0.0625}$

$=\dfrac{0.968245836552}{0.0625}$

$=15.4919333848\approx15.49$

Hence, the standard deviation of random variable K is closest to 15.49.

Therefore , the correct answer is d. 15.49 .

A 0.30 kg bird flies in a horizontal curve of radius 20 m at 15 m/s. The force exerted by the air on the bird is about

monitta

Answer:

<h2>b) 3.48 N approx.</h2>

Step-by-step explanation:

<em>The bird will experience a centripetal force, this is the force exerted on a body that moves through a curve path.</em>

$F_c = \frac{mv^2}{r}$

Fc=centripetal force

m=mass

v=velocity

r=radius

Step one:

given data

mass of bird m=0.3kg

the radius of curve r= 20m

velocity v= 15 m/s

Substituting we have

$F_c = \frac{0.3*15^2}{20}\\\\F_c= \frac{0.3*225}{20}\\\\ F_c=\frac{67.5}{20}\\\\F_c=3.37N$

<u>The force is 3.37N</u>
