The probability of selecting an odd number given that a green disk is selected is 75%.

There are only 4 green disks. Three of them have odd numbers: 3, 5, 7.

Therefore, there is a 3/4 chance that you select an odd number given that you have already selected a green disk.

Integers are any whole number(not fraction) that can be possitive or negative however she can not buy a negative amount of tickets so that is not the answer

1/2(-9 + y)=2.5 solve for why. Please show me your steps
Oksi-84 [34.3K]

Answer:

Y = 14

Step-by-step explanation:

1/2(-9 + y) = 2.5

1/2 * -9 = -4.5

1/2 * y = 0.5y

-4.5 + 0.5y = 2.5

+4.5             +4.5

0.5y = 7

/0.5   /0.5

y = 14

Mathematics 13 don’t understand
UNO [17]

Answer:

  1/6^3

Step-by-step explanation:

The applicable rules of exponents are ...

  a^-b = 1/a^b

  (a^b)(a^c) = a^(b+c)

__

Your expression can be simplified as follows:

  \dfrac{6^{-5}}{6^{-2}}=\dfrac{1}{(6^{-2})(6^5)}=\dfrac{1}{6^{-2+5}}=\boxed{\dfrac{1}{6^3}}

_____

<em>Additional comment</em>

If you think of an exponent as signifying repeated multiplication, the rules of exponents may be easier to remember. The exponent tells you how many times the base is a factor in the product.

Consider multiplication:

  (x\cdot x\cdot x)\cdot(x\cdot x)=x^3\cdot x^2=x^{3+2}=x^5\\\\(x\cdot x\cdot x)\cdot(x\cdot x\cdot x)=(x^3)^2=x^{3\cdot2}=x^6

Consider division:

  \dfrac{x\cdot x\cdot x}{x\cdot x}=x\quad\Longleftrightarrow\quad\dfrac{x^3}{x^2}=x^{3-2}=x^1\\\\\dfrac{x\cdot x}{x\cdot x\cdot x}=\dfrac{1}{x}\quad\Longleftrightarrow\quad\dfrac{x^2}{x^3}=x^{2-3}=x^{-1}

This may help you see that a positive exponent in the denominator is equivalent to a negative exponent in the numerator (and vice versa).

If you have 1 /18 profit out of 75 boxes how many more to make 180 dollars
krek1111 [17]
Assuming that means you make $0.06 per box (1/18 dollars per box) then you've made $4.17 off of the 75 boxes. 180-4.17 = 175.83 / .06 = 3165 more boxes.

You'd need to sell 3,165 more boxes.

a positive real number is 4 less than anther of the sum of the squares of the two numbers is 72 then find the numbers.​
ZanzabumX [31]

Answer:

3.657 and 7.657 to the nearest thousandth.

Step-by-step explanation:

x - y = 4

x^2 + y^2 = 72

From equation 1

x = y + 4 so

(y + 4)^2 + y^2 = 72

y^2 + 8y + 16 + y^2 - 72 = 0

2y^2 + 8y - 56 = 0

y^2 + 4y - 28 = 0

y = 3.657.

so x = 7.657.
