Answer: 9/25
Step-by-step explanation: .36 equals 36/100 in decimal form.
Reducing it into its simplest form:
Both numbers are divisible by 4-
36/100 = 9/25 - which is the simplest form.
Answer: 0.1310
Step-by-step explanation:
Given : Mean :
Standard deviation :
Sample size :
To find the probability that the sample mean would differ from the population mean by more than 1.9 millimeters i.e. less than 129.1 milliliters and less than 132.9 milliliters.
The formula for z-score :-
For x = 129.1 milliliters
For x = 132.9 milliliters
The P-value=
Hence, the required probability = 0.1310
The answer is the first option.
141 = (13x + 4) + (10x - 1)
141 = 23x + 3 <--- Combine like terms
141 = 23x -3
+3 +3 <--- Simplify by adding 3 to each side
-------------------
138 = 23x
/23 /23 <--- Simplify by dividing each side by 23
------------------
x = 6
