The Z-score (z) is calculated according to the formula: z = (x - μ) / σ
Where: x is the raw score value, μ is the mean of the population, σ is the standard deviation of the population.
x = 80, μ = 5, σ = 4
z = (80 - 5) / 4
z = 75 / 4 = 18.7500
Z-score is 18.7500
Answer:
Parallelograms
Step-by-step explanation:
Opposite sides are parallel by definition. Opposite sides are congruent. Opposite angles are congruent.
Answer:
(-2,3)
(-2,-2)
(4,-2)
Step-by-step explanation:
When moving a shape 5 units to a direction you usually just add or subtract. In this case you would add since it is going right. You only add the x coordinate cause that is the motion of going left to right. If it said up or down then you would add or subtract the y coordinate.
(-7,3) → (-2,3)
(-7,-2) → (-2,-2)
(-1,-2) → (4,-2)
Answer:
x = 10 and x = 2
Step-by-step explanation:
x² - 6x + 20 = 6x
x² - 12x + 20 = 0
We should have values of p and q that multiply and give the answer as 20 and if added give -12.
=> p * q = -10 * -2 = 20
=> p + q = -10 + (-2) = -12
Therefore, we can factor it now:
(x - 10) (x - 2) = 0
We can say:
x - 10 = 0, and x - 2 = 0
=> x = 0 + 10, and x = 0 + 2
=> <u>x = 10 and x = 2</u>
