Answer:
black = 0.28
white = 0.22
pink = 0.24
blue = 0.26
Step-by-step explanation:
Jason and his friend spun the spinner 100 times total. So for each time landed on a color, it can be counted as one percentage (for example, black had a 28% frequency). To transfer percentages to decimal form, simply bring the decimal point over by two spaces (28 becomes 0.28, something like 4 would become 0.04). Hope this helps! Feel free to ask any questions!

3x = 180
x = 60
12)
6x + 18 = 180
6x = 162
x = 27
To solve for the other leg, you need to use Pythagorean theory.
The theory states that C^2 = A^2 + B^2
In your case, you have to solve for B.
C = 40 (hypotenuse) A = 24 (leg 1)
The formula rewritten for B is
![b= \sqrt{c^{2}-a^{2} }](https://tex.z-dn.net/?f=b%3D%20%5Csqrt%7Bc%5E%7B2%7D-a%5E%7B2%7D%20%7D)
Now, you can solve.
![b= \sqrt{c^{2}-a^{2} } b= \sqrt{40^{2}-24^2 } b = \sqrt{1600 - 576} b = \sqrt{1024} b = 32](https://tex.z-dn.net/?f=b%3D%20%5Csqrt%7Bc%5E%7B2%7D-a%5E%7B2%7D%20%7D%0A%0Ab%3D%20%5Csqrt%7B40%5E%7B2%7D-24%5E2%20%7D%0A%0Ab%20%3D%20%5Csqrt%7B1600%20-%20576%7D%0A%0Ab%20%3D%20%5Csqrt%7B1024%7D%0A%0Ab%20%3D%2032)
Therefore, B = 32.
So the second leg is 32 feet.

Step-by-step explanation:
The average rainfall when you add all 10 years of rainfall up and divide by 10 is an average of 59.946 inches of rain each year. The equation for the data is y = -0.53x + 64.45, this means that the rainfall is getting less each year at a -0.53 inches of rain each year.
x = year (2004 would be 4, etc)
