Okay so you’re trying to get them to add up to 540 degrees.
On one side of the equation, have this, and on the other, add up your degrees on the shape.
(3x)+(10x-8)+(5x-12)+(120)+(2x)=540
Start by combining like terms on the left side.
20x+100=540
-100 -100
___________
20x=440
—— ——
20 20
x=22
(On this step, I was just solving and isolating the variable.)
Hope this helps!!
Answer:
15.90
Step-by-step explanation:
The formula for standard deviation, σ, of a population is
We can use a table to organize the calculations.
<u> x </u> <u>x - µ </u> <u>(x - µ)²
</u>
212 -18 324
249 19 361
212 -18 324
248 18 324
239 9 81
212 -18 324
216 -14 196
234 4 16
<u> 248 18 324</u>
2070 2274
Sum= 2070
N = 9
µ = Sum/N = 2070/9 = 230
The answer is B because Tom does not really want to change the possibilities that marbles that are not blue
Answer:
25:36
Step-by-step explanation:
Area of circle A = pi r^2 = pi (5)^2 = 25 pi
Circle b = 36 pi
ratio A: B = 25pi/36pi = 25:36
