Given a mean of 100, and a standard deviation of 5.3, what is the Z-score for 130?
Answers
Answer:
5.66038
Step-by-step explanation:
Given
Mean= μ=100
SD= σ=5.3
Z-score of 130= ?
The z-score of any value tells us that how many standard deviations that value is from the average or mean.
The Z-score of any data value is found by subtracting the mean from it and then dividing by the standard deviation.
z-score= (x- μ)/σ
z-score of 130= (130-100)/5.3
=30/5.3
=5.66038

Step-by-step explanation:
The division of an hexagon into 3 equal parts by Robert leaves you with three separated pieces of a whole, each one can be expressed by the fraction , since you only have one that´s your numerator, and in that part you just have to use the denominator of the number of that you divided the thing into, in this case it´s 3, so 3 it´s the denominator on the fraction.
Final answer:
The fraction that represents each equal part when a hexagon is divided into three equal parts is 1/3.
Explanation:
When a whole, in this case a hexagon, is divided into 3 equal parts, each part represents a fraction of the whole. Since there are 3 parts and each is equal, we can express each part as a fraction of the whole. The fraction is simply 1 (the part) over 3 (the total number of equal parts). Therefore, the fraction that names each part is 1/3.

Given the quadratic functions expressed as;
x² - 6x = 12
The value of p given the quadratic expression is -3
Complete the square at the left hand side of the equation.
Add the square of the half of coefficient of x to both sides.
coefficient of x = -6
Half of coefficient of x = -6/2 = -3
Square of the result = (-3)² = 9
Add 9 to both sides of the equation
x² - 6x + 9 = 12 + 9
Factoring the left hand side
(x-3)² = 21
Comparing the result with (x+p)² = q
The value of p wil be -3

Answer:
p = - 3
Step-by-step explanation:
Given
x² - 6x = 12
To obtain the required form use the method of completing the square
add ( half the coefficient of the x- term )² to both sides, thus
x² + 2(- 3)x + 9 = 12 + 9
(x - 3)² = 21
Thus p = - 3
