Answer: $3.30
Explanation:
You set up a proportion where
9.25 X
------ = -----
2.8 1
Then you cross multiply and see that...
2.8X = 9.25
Then X = 9.25 / 2.8 = 3.30
Answer:
1.39%
Step-by-step explanation:
(21 - 32) / 5 = -2.2 z score
= 0.0139 so there is a 1.39% probability
6% de 22,26 =
6*22,26/100 =
1,3356
22,26 - 1,3356 = 20,9244
70% de 20,9244 =
70*20,9244/100 =
14,64708 ~ 14,64
-5-8
Same signs so you add and keep the sign
when you add you get -13
5z-8=32
+8. +8
5z= 40
5/5=40/5
Z=8
