Answer:

1/3

Step-by-step explanation:

Simplify the following:

1 - 2/3

Put 1 - 2/3 over the common denominator 3. 1 - 2/3 = 3/3 - 2/3:

3/3 - 2/3

3/3 - 2/3 = (3 - 2)/3:

(3 - 2)/3

3 - 2 = 1:

Answer:  1/3

Answer: 0.0548

Step-by-step explanation:

Given, A research study investigated differences between male and female students. Based on the study results, we can assume the population mean and standard deviation for the GPA of male students are µ = 3.5 and σ = 0.05.

Let \overline{X} represents the sample mean GPA for each student.

Then, the probability that the random sample of 100 male students has a mean GPA greater than 3.42:

P(\overline{X}>3.42)=P(\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}>\dfrac{3.42-3.5}{\dfrac{0.5}{\sqrt{100}}})\\\\=P(Z>\dfrac{-0.08}{\dfrac{0.5}{10}})\ \ \ [Z=\dfrac{\overline{X}-\mu}{\dfrac{\sigma}{\sqrt{n}}}]\\\\=P(Z>1.6)\\\\=1-P(Z

hence, the required probability is 0.0548.

253. First, I squared 8, to get 64, then multiplied that by 12. I subtracted 9 from this because 3x3 is 9 to get 759. Then, divide this by 3 to get 253. Hope this helped!

Suppose the number of gallons of gasoline per day used by a car is normally distributed with a mean of 2.2 gallons and a standar
const2013 [10]
The difference in gallons per day used is 3.6.

The formula to calculate a z-score is:
z=\frac{X-\mu}{\sigma},

where X is the value used to calculate the score, μ is the mean and σ is the standard deviation.  We have the z-scores so we must work backward:

3=\frac{X-2.2}{1.2}\text{ and }0=\frac{X-2.2}{1.2}

For both equations, we will cancel the 1.2 by multiplying both sides:
3\times1.2=(\frac{X-2.2}{1.2})\times1.2\text{ and }0\times1.2=(\frac{X-2.2}{1.2})\times1.2
\\
\\3.6=X-2.2\text{ and }0=X-2.2

Now we will cancel 2.2 from both equations by adding it to both sides:

3.6+2.2=X-2.2+2.2     and       0+2.2=X-2.2+2.2
5.8=X     and       2.2=X

The difference in gas used per day would be given by
5.8-2.2 = 3.6.
