Answer:
The scanning electron microscope
Step-by-step explanation:
The scanning electron microscope can determine the proximity to a discharging firearm and/or the contact with a surface exposed to GSR
18 / 2 = 9 || 9 x 3 = 27. Therefore, 27 students are registered in Bob’s class.
Name Score
Julia 650
Andrew 550
Jason 380
Cathy 720
Jessica 710
Robert 550
Point estimate for the mean score:
Sample mean = sum of all observations / number of observations
sample mean = (650+550+380+720+710+550) / 6
sample mean = 3560 / 6
sample mean = 593.33
The point estimate for the mean score is 593.33
Answer:
B
Step-by-step explanation:
Variance can be said to be a measure of dispersion for a random sample.
Variance = pq/n
When given the variance, we can find the standard deviation.
Standard deviation = √variance
= √pq/n
Answer:
the slope is -4, b intercept is 9
Step-by-step explanation:
y=mx+b
y= (slope)x + (intercept)
