Solve by factoring: 2x2 - 5x - 12 = 0

Zepler [3.9K]

Step-by-step explanation:

$2 {x}^{2} - 5x - 12$

$2 {x}^{2} - 8x + 3x - 12$

$2x(x - 4) + 3(x - 4)$

$2x + 3 = 0 \: \: x - 4 = 0$

$x = \frac{ - 3}{2} \: \: x =4$

The probability density function of the time to failure of an electronic component in a copier (in hours) is f(x)= e^-x/100 /100

Georgia [21]

Answer:

Check the explanation

Step-by-step explanation:

The fundamentals

A continuous random variable can take infinite values in the range associated function of that variable. Consider $f\left( x \right)f(x)$ is a function of a continuous random variable within the range $\left[ {a,b} \right][a,b]$ , then the total probability in the range of the function is defined as:

$\int\limits_a^b {f\left( x \right)dx} = 1 a∫b f(x)dx=1$

The probability of the function $f\left( x \right)f(x)$ is always greater than 0. The cumulative distribution function is defined as:

$F\left( x \right) = P\left( {X \le x} \right)F(x)=P(X≤x)$

The cumulative distribution function for the random variable X has the property,

$0 \le F\left( x \right) \le 10≤F(x)≤1$

The probability density function for the random variable X has the properties,

$\\\begin{array}{c}\\{\rm{ }}f\left( x \right) \ge 0\\\\\int\limits_{ - \infty }^\infty {f\left( x \right)dx} = 1\\\\P\left( E \right) = \int\limits_E {f\left( x \right)dx} \\\end{array} f(x)≥0$

C= 5/9 (F−32)

Grace [21]

Answer:

C = 5/9 (F - 32)

This is a temperature scale change comparison.

By this we understand, that ,

1°C = 5/9°F

Which is equal to, 5/9°F = 1°C

These two statements are satisfied by I. and II.

So, the correct answers are, I. and II.

If my answer helped, kindly mark me as the brainliest!

Thank You!!
