Over x-axis = negative y value
Over y-axis = negative x value

Reflection around x-axis = (4, -5)
Reflection around y-axis = (-5, 4)

Solve the quadratic equation by factoring 9x2+24+20=4
AnnyKZ [126]

Answer:

Final answer is x=-\frac{4}{3} and x=-\frac{4}{3}.

Step-by-step explanation:

Given equation is 9x^2+24x+20=4.

Now we need to solve that by factoring.

9x^2+24x+20=4

9x^2+24x+20-4=0

9x^2+24x+16=0

9x^2+12x+12x+16=0

3x(3x+4)+4(3x+4)=0

(3x+4)(3x+4)=0

(3x+4)=0, (3x+4)=0

3x+4=0, 3x+4=0

3x=-4, 3x=-4

x=-\frac{4}{3}, x=-\frac{4}{3}

Hence final answer is x=-\frac{4}{3} and x=-\frac{4}{3}.

Suppose a brand of light bulbs is normally​ distributed, with a mean life of 1400 hr and a standard deviation of 150 hr. Find th
Mariulka [41]

Answer:

The probability that a light bulb of that brand lasts between 1175 hr and 1610 hr is 0.8524.

Step-by-step explanation:

Given : Suppose a brand of light bulbs is normally​ distributed, with a mean life of 1400 hr and a standard deviation of 150 hr.

To find : The probability that a light bulb of that brand lasts between 1175 hr and 1610 hr ?

Solution :

Applying z-score formula,

z=\frac{x-\mu}{\sigma}

where, \mu=1400 is population mean

\sigma=150 is standard deviation

For x=1175 hour,

z=\frac{1175-1400}{150}

z=\frac{-225}{150}

z=-1.5

For x=1610 hour,

z=\frac{1610-1400}{150}

z=\frac{210}{150}

z=1.4

The required probability is,

P(1175< X

P(1175< X

Using z table, the values are

P(1175< X

P(1175< X

The probability that a light bulb of that brand lasts between 1175 hr and 1610 hr is 0.8524.
