Complete Question
A population has a mean of 25, a median of 24, and a mode of 26. The standard deviation is 5. The value of the 16th percentile is _______. The range for the middle 3 standard deviation is _______.
Answer:
The value of the 16th percentile is
The range for the middle 3 standard deviation is
Step-by-step explanation:
From the question we are told that
The mean is
The median is
The mode is
The standard deviation is
Generally the 16th percentile is mathematically represented as
So
Now from the normal distribution table the z-score of 0.16 is
z = -1
=>
=>
=>
=>
The range for the middle 3 standard deviation is mathematically represented
Answer:
sin(x)=1/
Step-by-step explanation:
The trigonometric identities involve trigonometric functions. Here we will be using Trigonometric identity
sin²x = 1 /( 1+cot²x )
now cot(x)= -3
⇒ cot²x= (-3)²
⇒ cot²x= 9
sin²x= 1/( 1+9)
⇒ sin²x = 1/10
taking under root on both the sides we get
√sin²x=/
⇒ sin(x)=± 1/
