Answer:

1. You have: Sin(α)=Opposite/Hypotenuse α=10° Opposite=500 m Hypotenuse=x 2. When you substitute these values into Sin(α)=Opposite/Hypotenuse, you obtain: Sin(α)=Opposite/Hypotenuse Sin(10°)=500/x 3. Now, you must clear "x": x(Sin(10°))=500 x=500/Sin(10°) 4. Then, the value of "x" is: x=2879.4 m

The number of typing errors made by a typist has a Poisson distribution with an average of two errors per page. If more than two

wlad13 [49]

Answer: 0.6767

Step-by-step explanation:

Given : Mean = $\lambda=2$ errors per page

Let X be the number of errors in a particular page.

The formula to calculate the Poisson distribution is given by :_

$P(X=x)=\dfrac{e^{-\lambda}\lambda^x}{x!}$

Now, the probability that a randomly selected page does not need to be retyped is given by :-

$P(X\leq2)=P(0)+P(1)+P(2)\\\\=(\dfrac{e^{-2}2^0}{0!}+\dfrac{e^{-2}2^1}{1!}+\dfrac{e^{-2}2^2}{2!})\\\\=0.135335283237+0.270670566473+0.270670566473\\\\=0.676676416183\approx0.6767$

Hence, the required probability :- 0.6767

Area=?????? Please help!!???

LiRa [457]

Answer:

x^2 + 11x + 30

Step-by-step explanation:

Area of a rectangle = length x width

Length = x + 6

Width = x + 5

Area = (x + 6)(x + 5)

Using the distributive property, we have

x x x + x x 5 + 6 x x + 6 x 5

x^2 + 5x + 6x + 30

x^2 + 11x + 30
