Answer:
7.1
Step-by-step explanation:
write pythagorean theorem 
+ = 
2
= 100
divide 2 both side:
= 50
= 
=
= 7.07106781
round to nearest tenth:
= 7.1
X - 27
The coefficient is a number used to multiply a variable. The variable is x. The coefficient is : (understood but not written)...it is 1.
ur problem is actually 1x - 27.....however, the 1 is not usually written.
First divide 14 by 2 which brings you to 7. Now multiply 7 by 5 and your total number would be 35. Hope I helped!
Answer:
0.3667
0.2727
Step-by-step explanation:
a)
P (Blue) = P (large and Blue) + P (mid and Blue) + P (small and Blue)
P (Blue) = (0.5 * 0.2) + (0.4*7 / 12) + (0.1* 1 / 3)
P (Blue) = 0.3667
b)
Conditional Probability:
P (Large / Blue ) = P (large and Blue) / P ( Blue)
P (Large / Blue ) = 0.5*0.2 / 0.36667
P (Large / Blue ) = 0.2727
