Hence, write as single<br> frachon in its lowest terms.<br> 2/y-1 - 4/y^2-1
sleet_krkn [62]

Answer:

\frac{2}{y+1}

Step-by-step explanation:

Factorise the denominator of the second fraction

y² - 1 = (y - 1)(y + 1) ← difference of squares

To obtain a common denominator

multiply numerator/ denominator of first fraction by (y + 1)

= \frac{2(y+1)}{(y-1)(y+1)} - \frac{4}{(y-1)(y+1)} ← subtract numerators leaving the common denominator

= \frac{2y+2-4}{(y-1)(y+1)}

= \frac{2y-2}{(y-1)(y+1)}

= \frac{2(y-1)}{(y-1)(y+1)} ← cancel common factor (y - 1) on numerator/denominator

= \frac{2}{y+1}

3. A company manufactures light bulbs. The average lifetime for these bulbs is 4,000 hours with a standard deviation of 200 hrs.
Kisachek [45]

Answer: the company should promote 4412 hours for these bulbs.

Step-by-step explanation:

Assuming that the lives of the bulbs are normally distributed, we would apply the formula for normal distribution which is expressed as

z = (x - µ)/σ

Where

x = lifetime of the bulbs in hours.

µ = mean hours

σ = standard deviation

From the information given,

µ = 4000 hours

σ = 200 hours

If only 2% burn out, then the company would promote 98% would meet the claimed lifetime. Looking at the normal distribution table, the z score corresponding to a probability of 0.98 is 2.06. Therefore,

2.06 = (x - 4000)/200

Cross multiplying, it becomes

200 × 2.06 = (x - 4000)

412 = x - 4000

x = 4000 + 412

x = 4412 hours
