Answer: 2.14 %
Step-by-step explanation:
Given : pH measurements of a chemical solutions have
Mean : 
Standard deviation : 
Let X be the pH reading of a randomly selected customer chemical solution.
We assume pH measurements of this solution have a nearly symmetric/bell-curve distribution (i.e. normal distribution).
The z-score for the normal distribution is given by :-
For x = 6.74
For x = 6.76
The p-value =
In percent, 
Hence, the percent of pH measurements reading below 6.74 OR above 6.76 = 2.14%
Answer:
33 and 34
Step-by-step explanation:
Let the integers be x and x+1 respectively.
4x = 3(x+1) + 30
x = 33
therefore, the integers are 33 and 34

Answer:
GCF(greatest common factor) of 5 is 5.
Answer:
a. 12 years
b. 30 years
Step-by-step explanation:
a) Assume Liaqat's age is x. His age would be:
5x + 10 = 70
5x = 70- 10
x = (70 - 10) / 5
x = 12
<em>Liaqat is 12 years old.</em>
b. Assume his uncle's age is y;
4y - 10 = 130
4y = 130 - 10
y = (130 - 10) / 4
y = 30
<em>Liaqat's uncle is 30 years old. </em>
The answer is A I just answered it
