Since the problem is quite vague because the number of
choice per question is not written here. I’ll just put for 4 choices and 5
choices each.
To compute for the 5 choices each:
Mean = np = 20 (1/5) = 4
Standard deviation = sqrt(npq) = sqrt (4*(4/5) = 1.79
To compute for the 4 choices each:
Mean = np = 20 (1/4) = 5
Standard deviation = sqrt(npq) = sqrt (5*(4/5) = 2
Step-by-step explanation:
f ( - 4) = 3 ( - 4) ² - 2( - 4)
=. 3 ( 16) + 8
=. 48 + 8 = 56

B=Billionths
Answer:
First statement correct
Second statement not correct
You did it correctly though
Step-by-step explanation:
Since the lines have have same slope they would be parallel lines and never intersect each other hence inconsistent solution hence the first statement is correct.
A system of linear equations in which the two equations represent the same line; there are an infinite number of solutions to a dependent system, but these lines don't overlap each other hence no infinitely many solution thus not a dependent system and hence not correct
