We have these observations in this data: 15, 18, 46, 50, 50, 50, 50, 57.
The mean of these values is 
 \frac{15+18+46+50+50+50+50+57}{8} =42

In December it snowed 2 days for every 8 days it did not snow what percent of the days in December did it snow​
sergey [27]
I think it might be 20%. If in a total of 10 days it only snowed 2, then you could take 2/10, which is .2, then multiply by 100 to make it a percentage... which would be 20%.

find all the zeros and write a linear factorization of g(x)=x^4-8x^3+27x^2-50x+50 given that 1+2i is a zero
solmaris [256]

Answer:

g(x)= (x-(1+2i)) * (x-(1-2i)) * (x-(3-i)) * (x-(3+i))

Please see attached image

Step-by-step explanation:

We can easily solve this equation by using a technical solver or a programming language such as Octave.

The linear factorization of the equation can be obtained directly by finding the zeros of g(x)

Please see attached images for the answer to your problem

g(x)= (x-(1+2i)) * (x-(1-2i)) * (x-(3-i)) * (x-(3+i))

How do u solve this need answers
Ket [755]

By splitting the shape into a semi-circle and rectangle, we can see that we have a semi-circle with a diameter of 14 cm and a rectangle with dimensions of 28 cm by 15 cm. To find the area of the entire shape, we can add the areas of the two shapes up.


We can find the area of the semi-circle using the formula \frac{\pi r^2}{2}, where r is the radius of the semi-circle. In this case, the area would be:

\dfrac{\pi (14)^2}{2} = \dfrac{196\pi}{2} = 98 \pi \,\,\textrm{cm}^2


The formula for the area of a rectangle is lw, where l is the length of the rectangle and w is the width. In this case, the area would be:

(28)(15) = 420 \,\,\textrm{cm}^2


Thus, the area of the total shape is:

98 \pi \,\,\textrm{cm}^2+ 420 \,\,\textrm{cm}^2 \approx \boxed{727.88 \,\,\textrm{cm}^2}
