30 quarters because you times 6 by 5 and that equals 30 than you divine that by 4 and that 7.5
Hello!
You can distribute the 10
50x - 6 + 50
Combine like terms
50x = 44
Divide both sides by 50
x = 44/50
Simplify
x = 22/25 = 0.88
The answer is x = 0.88
Hope this helps!
Answer:It has to be more clear
Step-by-step explanation:
Answer:
"0.0125" is the right solution.
Step-by-step explanation:
The given values are:
Random sample,
n = 90
Claims,
p = 20%
or,
= 0.20
By using normal approximation, we get
⇒ 
On substituting the values, we get
⇒ 
⇒ 
Now,
The standard deviation will be:
⇒ 
On putting the above given values, we get
⇒ 
⇒ 
⇒ 
⇒ 
hence,
By using the continuity correction or the z-table, we get
⇒ 
⇒ 
⇒ 
From table,
⇒
