Answer:
a. yes
Step-by-step explanation:
If 16 - u = -4 and u = 20:
16 - 20 = -4
The equaton is correct, therefore the given value of u is the solution to the equation.
A chlorine nucleus will contain: Number of protons Z = 17. Number of protons + neutrons A = 35. Number of neutrons N = 35 - 17 = 18.
Answer:
-4x(5x-3)
Step-by-step explanation:
-20x^2 - 12x
-20x^2 = -4*5*x*x = -2*2*5*x*x
-12x = -4*3*x = -2*2*3*x
The common terms are -2*2*x = -4x. Whats left goes inside the parentheses
-4x(5x-3)
Answer: Standard error.
Step-by-step explanation:
If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean
[/tex] is known as standard error which depends on population standard deviation
and the sample size (n).

It measure the variability in the sample statistics that happens by chance.
Thus, the standard deviation of a sampling distribution is called the <u>standard error</u>.
