You can find the answer to that by dividing that equation or multiplying an answer you think it might be to that equation and see if you get 84
The upper number is NUMERATOR and below one is DENOMINATOR
Answer: the third one
Step-by-step explanation:Hope this is correct
Answer:
z = 1.5
Step-by-step explanation:
x - mean
standard score = -----------------
6
Substituting 74 for x, 65 for mean, we get:
74 - 65
standard score = ----------------- = 9/6 = 1.5
6
The pertinent z-score (standard score) is 1.5.
Center of circle 1 = (-4,-2)
Center of circle 2 = (5,3)
From -4 to 5 is a 9 unit move to the right.
From -2 to 3 is a 5 unit move up.
You would need to add 9 to the x value and 5 to the y value.
The transformation rule would be (x+9, y+5)
The radius of circle 2 is twice the length of circle 1, so to make the radius of circle 1 the same as circle 2 multiple it by 2, this is the scale factor.
Scale factor = 2
