Goryan [66]

Answer:

Probabilty= 0.0015355

Step-by-step explanation:

Flaws in a carpet tend to occur randomly and independently at a rate of one every 270 square feet.

Probabilty= 1/270

Probabilty= 0.0037

carpet that is 8 feet by 14 feet

Area=8*14

Area=112 square feet

Probabilty= 0.0037*(112/270)

Probabilty= 0.0037*0.415

Probabilty= 0.0015355

the numerator of a fraction x/y is 2 less than the denominator. If 3 is added to both the numerator and denominator, then the su

Mashutka [201]

Answer:

Step-by-step explanation:

Fraction :x/y

numerator x = y - 2

Now the fraction can be written as: (y-2)/y

3 is added to both denominator and numerator.

After adding 3, the new fraction = $\frac{y-2 +3 }{y + 3 } = \frac{y+ 1 }{y +3}$

The sum of the new fraction and the original fraction is 53/35

$\frac{y+1}{y+3} + \frac{y-2}{y} = \frac{53}{35}\\\\\frac{(y+1)*y}{(y+3)*y}+\frac{(y-2)*(y+3)}{y(y+3)}=\frac{53}{35}\\\\\frac{y^{2}+y}{y^{2}+3y}+\frac{y^{2}+y-6}{y^{2}+3y}=\frac{53}{35}\\\\\frac{y^{2}+y+y^{2}+y-6}{y^{2}+3y}=\frac{53}{35}\\\\\frac{2y^{2} + 2y - 6}{y^{2}+3y}=\frac{53}{35}\\\\$

35*(2y² + 2y - 6) = 53 *(y² + 3y)

35*2y² + 2y * 35 - 6*35 = 53 *y² + 53*3y

70y² + 70y - 210 = 53y² + 159y

70y² + 70y - 210 - 53y² - 159y = 0

70y² - 53y² + 70y - 159y - 210 = 0

17y² - 89y - 210 = 0
