The probability would be 1/15. 
The first draw, taking a gold coin is 3/10. 
Since we don't replace it, we draw again, but a value less- 2/9. 
We multiply that together and get 6/90, then simplify it :)<span />

The asking price for homes on the real estate market in Baltimore has a mean value of​ $286,455 and a standard deviation of​ $11
Stella [2.4K]

Answer:

c)

Step-by-step explanation:

The asking price in Baltimore has a mean value of $286,455 and a standard deviation of $11,200; this means that most houses prices fall between $275,255 and $297,655.

Similarly, the mean value in Denver is $188,468 and a standard deviation of $8,230; most houses prices fall between $180,238 and $196,698.

The problem tells us that one home sold in each city where the asking price for each home was $193,000. In the case of Denver this would be expected (values usually fall between 180,000 and 196500 approximately).

However, the house in Baltimore is relatively farther from the mean than the one in Denver because the price is more than one standard deviation away from the mean.

Therefore, the correct answer is C. The house in Baltimore is relatively farther from the mean than the house in Denver.

A guy-wire is attached to a pole for support. If the angle of elevation to the pole is 67° and the wire is attached to the groun
vovangra [49]
You have to go at this in a round-about fashion...by finding the length of the leg across from the 67 degree angle.  This is found by using the tangent ratio...Tan(67)=x/137; x=137tan(67) = 322.8. Now you can use this in one of two ways: use Pythagorean's Theorem to find the length of the hypotenuse OR you could use the sin67=322.8/x.  Up to you. Either way, make sure you have your calculator in degree mode!

Answer:

38= 2×19

39= 3×13

40= 2×2×2×5

hcf = highest common factor = 1

if you can't seen any common factor then write 1 , it's common in all.

if all the number divide by same number, then it's common in factor
