The answer is z score of 2.00 is most desirable because it is 2.00 standard deviations beyond the mean and would agree to the highest of the five diverse likely test scores. In addition, the number of standard deviations that a given value x is above or below the mean is the z score or as called as standardized value. The negative z score agrees to an x value less than the mean while a positive z score agrees to an x value larger than the mean. The more negative the z score the more the x value is under the mean and the further positive the z score the more the x value is below the mean.
You have to use a proportion.
3.5/18= 1.5/x
3.5x=27
x= 7.7 cm
Answer:
Therefore, x = -2m+4/-n-1
Answer:
x=√16
Step-by-step explanation:
-3x^2=48
First, we divide by -3 on both sides of the equation.
x^2=16
Then we find the square root of both sides.
x=√16
