Answer:
The 315 hours is the value of a: statistic
Step-by-step explanation:
A random sample of 650 power cells is tested and the average lifetime of this sample is found to be 315 hours.
The 315 hours is the value of a: statistic
A statistic is defined as a characteristic of a sample. It is used to estimate the value of a population parameter.
Just like here where a random sample of 650 power cells were taken for a test. And 315 hours is an example of a statistic.
Answer:
x > 0
Step-by-step explanation:
6x -12 > -12
6x > -12 +12
6x > 0
x > 0/6
x > 0
See attachment for math work.
(-3,-4) (3, 0)
slope = (0 +4) / (3 + 3) = 4/6 = 2/3
perpendicular so slope = -3/2
line on graph
y = mx + b
0 = 2/3 (3) + b
0 = 2+ b
b = -2
y intercept (0,-2)
answer
<span>The slope is -3/2 and contains the point (0, −2). </span>
