Answer:
First table (far left)
Step-by-step explanation:
The far-left table is the only function with a constant rate. All other tables do not contain this.
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.
X - 2x =6
X= - 6
Let x = −6
−6=2×−6+6
Simplify
2 ×−6 to −12
−6=−12+6
Simplify -12+6 to -6
-6= -6
Answer:
2
Step-by-step explanation:
The slope of a line can be found by finding the change in change in the y values over the change in the x values:
Where y2 is the second y point and y1 is the first point, same the with x values
So:
7-3 = 4
5-3 = 2
4/2 = 2
So the slope is 2
Second side= x
First side = 2x
Third side = x+5
x+2x+x+5=49
4x=44
x=11
1st side= 22
2nd side = 11
3rd side = 16
