Answer:

y = -29/19  and x = -44/19

Step-by-step explanation:

3x + 2y = -10    multiply by -2  ⇔    -6x -  4y = 20

2x - 5y = 3       multiply by 3   ⇔    <u>  6x - 15y = 9    </u>

Add the two equation                             -19y = 29

                                                                       y =  -29/19

Use equation one and solve for x

3x + 2(-29/19) = -10

3x - 58/19 = -10

3x = -10 + 58/19

3x = -190/19 + 58/19

3x = (-190 + 58)/19

  3x = -132/19

    x =  - 132/ 19 ÷3                           \frac{-132}{19} (\frac{1}{3} ) = \frac{-44}{19}

    x =  -44/19

Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of 2,250,000 and a mean
Svet_ta [14]

Answer: 0.1357

Step-by-step explanation:

Given : Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a variance of \sigma^2=2,250,000 and a mean life span of \mu=13,000 hours.

Here , \sigma=\sqrt{2250000}=1500

Let x represents  the life span of a monitor.

Then , the probability that the life span of the monitor will be more than 14,650 hours will be :-

P(x>14650)=P(\dfrac{x-\mu}{\sigma}>\dfrac{14650-13000}{1500})\\\\=P(z>1.1)=1-P(z\leq1.1)\ \ [\because\ P(Z>z)=1-P(Z\leq z)]\\\\=1-0.8643339=0.1356661\approx0.1357

Hence, the probability that the life span of the monitor will be more than 14,650 hours = 0.1357
