Answer:

x=(-1/2) y=(3/2)

Step-by-step explanation:

y=x+2 Given

-3x=x+2 Substitute (-3x) for y

-2-3x=x Subtract 2 from both sides

-2=4x Add 3x to both sides

(-1/2)=x Divide both sides by 4.

y=x+2 Given

y=(-1/2)+2 Substitute (-1/2) for x

y=1 1/2

y=3/2

Given the differential Equation y'+2y=2e^x ;solve this equation using the integration factor; solve for y to get the general sol

SCORPION-xisa [38]

$y'+2y=2e^x\Longrightarrow y'=2e^x-2y$

If $f'(x)=g(x)$ then $y=\int{g(x)dx}$

So we extract,

$y=\int{2e^x-2x}dx$

Which becomes,

$y=2e^x-x^2+C$

Hope this helps.

A continuous random variable may assume :

vova2212 [387]

Answer:

Option A) any numerical value in an interval or collection of intervals

Step-by-step explanation:

Continuous Random Variable:

A continuous random variable can take any value within an interval.
Thus, it can take infinite values since there are infinite numbers in an interval.
A continuous variable is a variable whose value is obtained by measuring.
Examples: height of students in class , weight of students in class, time it takes to get to school, distance traveled between classes.
Thus, the correct meaning of continuous random variable is explained by Option A)

Option A) any numerical value in an interval or collection of intervals

The probability of something can be expressed as a decimal or as a percent. We know that the probability of something happening

Firdavs [7]

Answer: The probability lies between 0 and 1

Step-by-step explanation:

As from the given information probability of an event lies between 0% to 100% .

To convert percent into integer or fraction we have to divide it by 100

$0\%= \frac{0}{100} = 0$

And

$100\% = \frac{100}{100} = 1$

From the above the probability of an event lie between integers 0 to 1.
