Answer:
0.00939495805 about 0.01
Step-by-step explanation:
basically solving for arccos(8.5/9.9) in degrees, had to run through calculator
4/9*3/9= 12/81=4/27
You have a 4 in 27 chance of drawing a red then a blue.
Answer:
-7/25
Step-by-step explanation:
Could be in fraction:
-7/25
or in decimal expression:
-0.28
The answer should be f(x)=20(2.5)^x
How?
the graph crosses the f(x) axis at 20 but that's common in all 4 equations. However, when x=1, f(x)=50. We have to know try all the equations by substituting these values in ( both sides are equal).
f(x)=20(2.5)^x
substitute f(x)=50, x=1
50=20(2.5)^1
50=20*2.5
50=50
