The answer is c, 8/3 (6) - 16 = 0 therefore 6 is the zero
Answer:
n = 484
Step-by-step explanation:
If Confidence Interval CI = 95 % then α = 5% and α/2 = 2,5 %
α/2 = 0,0125
MOE for normal distribution is:
MOE = z * σ/√n
For α/2 = 0,0125 ⇒ z(score) = -2,2
MOE = |-2,2| * 4/√n
0,4*√n = 8,8
√n = 8,8 / 0,4
√n = 22
n = 484
Answer:
Step-by-step explanation:
13=3x+4
subtract 4 from both sides
9=3x
divide by 3
x=3
Answer:
i really feel bad cause i had this question and got it right but know i do not the answer
Step-by-step explanation:
Answer:
x = -1
Step-by-step explanation:
Let the mystery number be x
Equation:
60 - 4x = 8x + 72
Subtract 60 from both sides
-4x = 8x + 12
Subtract 8x from both sides
-12x = 12
x = -1
