14 = 3x - 7
Subtract 7 from both sides.
7 = 3x
Divide both sides by 3
2.333333 = x
4.75 = 4 75/100 =
= 475/100 = ( we can divide numerator and denominator by 25 ) = 19/4
Answer:
4.75 as an improper fraction in simplest form is 19/4.
Answer:
0.9127
Step-by-step explanation:
We solve using this z score formula
z = (x-μ)/√n
where x is the raw score
We are told that:
The sample mean would differ from the population mean by less than 231 miles
μ is the population mean = 49360
Hence,
(x-μ) = 231 Miles
σ is the population standard deviation.
We were given variance = 6,568,969
Standard deviation = √variance
= √6,568,969
= 2563
n = random number of tires = 247 tires
z = 231/256/√247
z = 1.41648
Probability value from Z-Table:
P(x < 49591) = 0.92168
≈ 0.9217
The probability that the sample mean would differ from the population mean by less than 231 miles in a sample of 247 tires if the manager is correct is 0.9127
That would be Option C (Answer).
The translation to an equation of the mathematical statement given as The area A of a square is the length of a side L squared is A = L^2
<h3>How to translate the statement to an equation?</h3>
The mathematical statement is given as:
The area A of a square is the length of a side L squared
The above expression can be rewritten as:
The area A of a square = the length of a side L squared
Squared is represented as ^2
So, we have:
The area A of a square = the length of a side L^2
The above expression can be rewritten as:
The area A of a square = L^2
Lastly, the above expression can be rewritten as:
A = L^2
Hence, the translation to an equation of the mathematical statement given as The area A of a square is the length of a side L squared is A = L^2
