Hi.

The answer is no/false, as long as all the dots in the scatter plot follow the generic pattern of the line, it is fine. The line does not need to touch the dots.

Giải phương trình vi phân<br> a. dy/dx<br> b. y' + 2xy = 4x
WITCHER [35]

Your first differential equation is incomplete, so I'll just look at the second one.

<em>y'</em> + 2<em>xy</em> = 4<em>x</em>

Multiply both sides by exp(<em>x</em> ²):

exp(<em>x</em> ²) <em>y'</em> + 2<em>x</em> exp(<em>x</em> ²) <em>y</em> = 4<em>x</em> exp(<em>x</em> ²)

The left side is the derivative of a product:

(exp(<em>x</em> ²) <em>y</em> )<em>'</em> = 4<em>x</em> exp(<em>x</em> ²)

Integrate both sides:

exp(<em>x</em> ²) <em>y</em> = ∫ 4<em>x</em> exp(<em>x</em> ²) d<em>x</em>

For the integral, substitute <em>u</em> = <em>x</em> ² and d<em>u</em> = 2<em>x</em> d<em>x</em> :

exp(<em>x</em> ²) <em>y</em> = 2 ∫ exp(<em>u</em>) d<em>u</em>

Solve for <em>y</em> :

exp(<em>x</em> ²) <em>y</em> = 2 exp(<em>u</em>) + <em>C</em>

exp(<em>x</em> ²) <em>y</em> = 2 exp(<em>x</em> ²) + <em>C</em>

<em>y</em> = 2 + <em>C</em> exp(-<em>x</em> ²)

Roxanne likes to fish. She estimates that 30% of the fish she catches are
padilas [110]

The estimated probability that at least one of the next four fish Roxanne catches will be a perch is 34%

<h3>What is Probability ?</h3>

Probability is the likeliness of an event to happen. It has a range of 0 to 1, where 0 indicates uncertainty and 1 indicates certainty.

It is given that

0, 1, and 2 represent trout , 3 and 4 represent bass , 5 represent perch , 6, 7, 8, and 9 represent other fish

From the data it can be observed that

Total number of single digits numbers = 80

No. of Perch , "5 " = 8

Probability of getting a perch in next fish = 8/80 = 0.1

Probability that at least one of the next four fish Roxanne catches will be a perch = 1- P(no perch)

P ( no perch) = 1 - 0.1 = 0.9

for 4 fishes

= 1 - 0.9⁴

= 0.3439

= 34.39%

≈ 34%

Therefore the estimated probability that at least one of the next four fish

Roxanne catches will be a perch is 34%.
