Answer:
b is the right answer for my answer
To determine the answer to this item, we first calculate the z-scores of the given data point through the equation,
z-score = (data point - mean) / standard deviation
For 5:
z-score = (5 - 7) / 1.7 = -1.176
This translates to a percentile of 11.97.
For 10:
z-score = (10 - 7) / 1.7 = 1.76
This translates to a percentile of 96.08.
The difference between the percentiles is 84.11. Thus, 84% of the students sleep between 5 to 10 hours.
Answer:
43
Step-by-step explanation:
angle sum property of quadrilateral
87+ 103 + 127+ x = 360
317 + x = 360
x= 360-317
x = 43
Answer:
In this order from top to bottom, you get -12, -8, 0, 6, and 8
Step-by-step explanation:
You simply plug in the X value into each equation where it is needed.
So for the first one
2(-5)-2 = -10-2 = -12
2(-3)-2 = -6-2 = -8
2(1)-2 = 2-2 = 0
2(4)-2 = 8-2 = 6
2(5)-2 = 10-2 = 8
