You can’t record how clean someone’s hair is it depends on how they wash it and they probably wash it different every time. You could measure how dry their hair is after using that certain company’s shampoo.
0.84(because 20% of the observations are about 0.84)
You've found the 80th percentile! The 80th percentile of the standard normal distribution is 0.84. That's because 80% of the observations fall below 0.84. (Note: The 80th percentile of every normal distribution is 0.84 times the standard deviation above the mean.)
Answer:
The answer is x=1/2 or x=0.5
Answer:
B
Step-by-step explanation:
Using the cofunction identity
sin(90 - x)° = cosx°
Here x = 25° , then
cos25° = sin(90 - 25)° = sin65°
The 4 in the ones place is valued at 4, while the other at the tens place is valued at 40.
