Answer:
2e⁻² ≈ 0.271
Step-by-step explanation:
This is actually a Poisson distribution. The probability is:
P(x; μ) = e^(-μ) (μˣ) / x!
P(2; 2) = e⁻² (2²) / 2!
P(2; 2) = 2e⁻²
P(2; 2) ≈ 0.271
Answer:
27,000 meters
Step-by-step explanation:
Okay, here we have this:
Considering the provided angle, we are going to calculate the requested cosine, so we obtain the following:
Then to obtain the cosine we will review the following image of the unit triangle:
So since pi radians is equal to 180°, we can see in the image that the cosine of 180 degrees is equal to -1, so we finally get that the cosine of the angle is -1.
The amount of paper that Lemon needs for the actual poster will be 8 square feet.
<h3>What is a rectangle?</h3>
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
The dimension of the poster is 10 cm by 20 cm.
And the scale factor will be 5 cm is equal to 1 ft.
Then the dimension of the poster will be 2 ft by 4 ft.
Then the amount of the paper that Lemon needs for the actual poster will be
Area = 2 × 4
Area = 8 ft²
