Μ = x(bar) + or - 1.96(0.5)
= 5 + or - 0.98
5-0.98 =< μ =< 5 + 0.98
4.02 =< μ =< 5.98

Answer:
40 mL of 10% acid
80 mL of 25% acid
Step-by-step explanation:
x = volume of 10% acid solution
y = volume of 25% acid solution
Total volume is:
x + y = 120
Total amount of acid is:
0.10 x + 0.25 y = 0.20 (120)
Solve by substitution.
0.10 x + 0.25 (120 − x) = 0.20 (120)
0.10 x + 30 − 0.25 x = 24
0.15 x = 6
x = 40
y = 80
Answer: Probability of getting one volcano in the world on which to conduct an extensive study is
Step-by-step explanation:
Since we have given that
Number of cinder cone volcanoes = 13
Number of shield volcanoes = 18
Number of stratovolcanoes = 6
Total number of volcanoes is given by
So, Probability of selecting one volcano in the world on which to conduct an extensive study is given by
Hence, Probability of getting one volcano in the world on which to conduct an extensive study is
