___________________________________________
Explanation:
_________________________________

(20/100) x = 14; solve for "x".

(20/100) = 2/10 = 1/5 ;

(1/5) x = 14

x/5 = 14 ;

x = 14 * 5 ;

Doss [256]

Answer:

Step-by-step explanation: First you would do this 1260.90 divided by 6 = 210. So then you would multiply 210 x 2 = 420. $420 is how much the people who are staying for 6 days. Then since we know it’s $210 per day, we would subtract $420 from 1260.90 and we would get 840.90. Divide that by 6 and get 140. 140 is how much those two people are paying for 2 nights.

Find the terminal point on the unit circle determined by pi radians.

svet-max [94.6K]

Answer:

Terminal points

$(x,y) = (\frac{1}{\sqrt{2} }) , (\frac{-1}{\sqrt{2} })$

Step-by-step explanation:

According to the question, it is provided that

$\theta = \frac{7\pi}{4}$

Now

$x = 1. cos (\frac{7\pi}{4})\\\\ = cos (2\pi - \frac{\pi}{4})\\\\= cos \frac{\pi}{4} \\\\= \frac{1}{\sqrt{2} }$

$y = 1. sin (\frac{7\pi}{4})\\\\ = sin (2\pi - \frac{\pi}{4})\\\\= -sin \frac{\pi}{4} \\\\= \frac{-1}{\sqrt{2} }$

Now

$(x,y) = (\frac{1}{\sqrt{2} }) , (\frac{-1}{\sqrt{2} })$

These two represents the terminal points

We simply applied the above equations and then equate these two equations to determine the terminal points and therefore the same is to be considered

It could be figure out by using the x and y points

Therefore the two shows the terminal points

Home sizes in Anytown, USA have a mean of 2400 square feet and a standard deviation of 450 square feet. What is the probability

lesya [120]

Answer:

0.00084

Step-by-step explanation:

We are given that

Mean, $\mu=2400$ square feet

Standard deviation, $\sigma=450$ square feet

n=50

We have to find the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet.

$P(x$

$P(x$

Using the formula

$z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}$

$P(x$

$P(X$

Hence, the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet=0.00084
