First, we solve to find out what percent of the population has brown eyes and black hair. There are 303 people total, and 64 people with the description. After dividing, we find that about 21% of people have black hair and brown eyes.
Next, we use the chart to see that 9 out of the total 303 people have black hair and blue eyes. We divide this and see that this is only about 3%.
Last, we subtract 3 from 21 and get 18%
So, the answer is 18%

9/303 = 0.0297029703 or 3%

64/303 = 0.2112211221 or 21%

21% - 3% = 18% as the answer.

Find the surface area of a rectangular prism measuring<br> 5 m by 8 m by 9 m.
olganol [36]
The formula of the surface area of the rectangular prism is equal:
A=2(wl+wh+lh)
where:
l - length
w - width
h - height
We have:
l = 5m
w = 8m
h = 9m
Substitute:
A=2\cdot(5\cdot8+5\cdot9+8\cdot9)=2\cdot(40+45+72)=2\cdot157=314\ m^2

Match the function to the correct parabola
Lisa [10]

Answer:

The box to the left will have the equation p(x) = 5x² and the box to the right will have the equation n(x) = \frac{1}{5} x^{2}

Step-by-step explanation:

The coefficient of the x² decides how wide or narrow a quadratic graph is. If the coefficient is a fraction of 1, the smaller the fraction the wider the graph gets. If the coefficient is a number bigger than 1, the bigger the number, the narrower the graph gets.
