Answer:
approximately Normal with a mean of 3.2 million and a standard deviation of 0.32 million
Step-by-step explanation:
For normal distribution conditions
1) Sample size is greater than 30
2) Population standard deviation is known
3) population is normal distributed
Above any condition given problem if satisfied than it's distribution will approximately normal.
n = 40 > 30
Sample size(n) greater than 30 and population standard deviation is known.
So the distribution will approximately be normal

The solution to the system is (1, 5)
Answer:
These are all the same questions with one answer. 0.6 is greater than 0.571. Therefore, 3/5 is greater than 4/7 and the answer to the question "Is 3/5 greater than 4/7?" is yes.
Step-by-step explanation:
Answer:
Step-by-step explanation:
To find the equation of a line using slope and a point, first use the slope to create the basic line using the slope and work from there.
For instance, the base equation here is
This line passes through the point (0, 0).
You can then plug in a value for x. In this case, use the value of 3, as it corresponds with your question.
A point on the line of y = 2x would thus be (3, 6).
To make the y-value equal -3, you must then subtract from the original equation. There are 9 units between 6 and -3, so you must subtract nine units in the equation. You should get this at the end:
Answer:
$0.3 per cookie
Step-by-step explanation:
a dozen is 12 cookies. 2*12 = 24.
7.20/24 = 0.3
so each cookie costs 0.3 dollars
