Answer:
Last one
Step-by-step explanation:
You can simplify the first one or compare both of them if they have the same ratios! Hope this helps <3
Margin of error formula:
ME = z * (Sigma) / √ n
z = 1.96 for a 95 % confidence interval;
Sigma = 3 ( the population standard deviation )
n = 500
ME = 1.96 * 3 / √500 =
= 1.96 * 3 / 22.36 =
= 5.88 / 22.36 = 0.263
Answer:
The margin error for a 95% confidence interval is 0.263.
0.3+0.25= 0.55
1-0.55= 0.45
0.45(60)= 27
Karina has $27 left.
Probability=(number of favorable outcomes)/(number of total outcomes)
A=select the first gold fish.
P(A)=14/40
B=select the second gold fish
P(B)=13/39
A<span>∩B=select two fish gold
P(A</span><span>∩B)=P(A)*P(B)=(14/40)*(13/39)=182/1560=91/780
Answer: C. 91/780</span>
