1. To simplify -(x-4) change the sign on each term inside parenthesis:
-(x-4) would become -x+4
The answer is B.
2. -4xy / 3x
Cancwl the common factor out
-4xy / 3x (cross out the x's)
-4y /3
The answer is C.
Answer:
Statement A and C are true about the normal distribution.
Step-by-step explanation:
We have to identify true statements for normal distribution.
A) True
The mean, median and mode for a normal distribution are same
B) False
The parameters of normal distribution are mean and the standard deviation.
C) True
According to Empirical rule for normal distribution about two-third of data lies within plus or minus one standard deviation from the mean.
D) False
Normal distribution is a continuous probability distribution.
The volume of a cube formula is v(s)=s^3. If you plug in 3 for s, you will find that v(s) would in fact equal 27. Thus the length of the sides are 3 and the volume is 27.
Hey there!!
Things to remember:
- √ = something raised to the power 1/2
Given:
... √(10000x⁶⁴)
We can write this as:
... (√10000)×(√x⁶⁴)
The root of 10000 is 100
... 100×(x⁶⁴)¹/²
... 100 × x^64/2
... 100 × x^32
Hence, the answer is :
... <em>100x³² </em>
<em>Hope my answer helps!</em>
