There is a 3% chance of each light bulb being defective, and we only want 5 of them to be defective. The chance is then:

3\%^5*97\%^{25}

Or this really small number: 1.13474853e-8

Limit xtens to 0 x^2logx^2 what is the ans of interminate forms?
GarryVolchara [31]

Rewrite the limit as

\displaystyle\lim_{x\to0}x^2\log x^2=\lim_{x\to0}\frac{\log x^2}{\frac1{x^2}}

Then both numerator and denominator approach infinity (with different signs, but that's not important). Applying L'Hopital's rule, we get

\displaystyle\lim_{x\to0}\frac{\log x^2}{\frac1{x^2}}=\lim_{x\to0}\frac{\frac2x}{-\frac2{x^3}}=\lim_{x\to0}-x^2=\boxed{0}

Solve the inequality <br><br><br> what is the solution?
bija089 [108]

Answer:

The solution to the inequality is:

2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}

Please also check the graph of the solution to the inequality.

Step-by-step explanation:

Given the inequality

2\ge \frac{g}{-4}

switch sides

\frac{g}{-4}\le \:2

Multiply both sides by -1 (reverse the inequality)

\frac{g\left(-1\right)}{-4}\ge \:2\left(-1\right)

Simplify

\frac{g}{4}\ge \:-2

Multiply both sides by 4

\frac{4g}{4}\ge \:4\left(-2\right)

Simplify

g\ge \:-8

Therefore, the solution to the inequality is:

2\ge \frac{g}{-4}\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:g\ge \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:[-8,\:\infty \:)\end{bmatrix}

Please also check the graph of the solution to the inequality.

Find the area of this shape. Round your answer to the nearest tenth
MrMuchimi

Answer:

The area of this figure is 31,29.

Step-by-step explanation:

We have to find also the area of the rectangle, then we will find the area of the circle and divide by 2 because here is a half circle.

area of the rectangle = b x h

area of the rectangle = 6 x 6

area of the rectangle = 36

diameter = 6

r = d : 2

r = 6 : 2

r = 3 ft

area of the circle = π x r²

area of the circle = 3,14 x 3 ft

area of the circle = 9,42 ft

area of half of circle = 9,42 : 2 = 4,71 ft

area of this figure = area of rectangle - area of half of the circle

area of this figure = 36 - 4,71

area of this figure = 31,29

So the area of this figure is 31,29.

I hope this is helpful. :)
