ver the past three years, the mean score on the Graduate Management Admission Test (GMAT) for the population of 782,462 students who took it was 547.35 with a standard deviation of 121.08. a. Suppose that every possible sample of size 85 was taken from the population of 782,462 students and the sample mean test score was computed for each of these samples. What value should we expect the average of these sample mean test scores to equal
We should expect the average of these sample mean test scores to equal 547.35, using the Central Limit Theorem.
Central Limit TheoremThe Central Limit Theorem defines the distribution of the sampling distribution of sample means with size n of a normally distributed variable with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex].
For the sampling distribution, the mean and the standard deviation are given as follows:Mean: [tex]\mu[/tex], that is, the same as the population mean.Standard deviation: [tex]s = \frac{\sigma}{\sqrt{n}}[/tex], which is the population standard deviation divided by the square root of the sample size.For a skewed, that is, a non-normal variable, the sampling distribution is also approximately normal, as long as n is at least 30.
Hence, we should expect the average of these sample mean test scores to equal the population mean of 547.35.

-6 or 7 ( < or >) which describes the relationship between the numbers?
Answer:
<
Step-by-step explanation:
-6 is smaller than 7 while 7 is greater than -6, denoted by <.
-6 < 7.
On a number line, -6 comes to the left side of 0, six places after 0, denoting that -6 is smaller than 0. We know that 7 is greater than 0 and comes to the right side of 0. This shows that -6 is smaller than 7.

“Is it better to buy two 4” pizzas for ten dollars or one 7” pizza for the same price?” Use a mathematical strategy of your choice to discover the answer. Then, explain why it is better to buy either two 4” pizzas or one 7” pizza.
Answer:
It's better to buy 2- 4"
Step-by-step explanation:
2 x 4" = 8"
So if you buy 2-4" pizzas, you get a total of eight inch pizzas if you add them together. SO you would get 2-4" pizzas for 10$. Which is the same price as a 7" pizza
Write an equation of the line that passes through (-2, 0) and is perpendicular to the line y=-1/3x+3
Slope of y = -⅓x + 3 is -⅓ (on comparing with m of y = mx + c)
As the required line is perpendicular to this, slope of the required line = - 1 / (-⅓) = 3
Equation:
=> y - y1 = m(x - x1)
=> y - 0 = (3)(x - (-2))
=> y = 3(x + 2)
=> 3x - y + 6 = 0

After serving out 24 gallons, a milk tank had 24 pints left. How much milk was in the tank to begin with?
Answer:
216 pints or 27 gallons
Step-by-step explanation:
Basically you have to convert the gallons into pints to make it easier to add.
1 gallon = 8 pints
To turn 24 gallons into pints, multiply 24*8= 192.
So, now you just add 24+192 which is 216.
To convert into gallons, divide by 8 so it is 27.
216 pints or 27 gallons
Hope this helps!!

(Can I get brainliest?)
The amount of milk initially in the tank is 27 gallons.
After serving out 24 gallons, the number of pints left =24 pints
How many pints is equivalent to 1 gallon?1 gallon equals 8 pints.
So, 8 pints =1 gallon
1 pint = 1/8 gallon
24 pints =1/8 *24 = 3 gallons
So, the amount of milk initially in the tank = 24 gallons + 3 gallons
Amount of milk initially in the tank = 27 gallons.
Thus, the amount of milk initially in the tank is 27 gallons.
