Answer:
0.00084
Step-by-step explanation:
We are given that
Mean,
square feet
Standard deviation,
square feet
n=50
We have to find the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet.


Using the formula



Hence, the probability that a random sample of 50 homes in Anytown, USA has mean square footage less than 2200 square feet=0.00084
The answer is B hope this helps.
Answer:
792 ounces
Step-by-step explanation:
The equations below model the ounces of water, y, in each container after x minutes.
Container A: y = 62x + 48
Container B: y = -2x² + 80x + 120
Now, at a time when both the containers hold the same amount of water, is given by
62x + 48 = -2x² + 80x + 120
⇒ 2x² - 18x - 72 = 0
⇒ x² - 9x - 36 = 0
⇒ x² - 12x + 3x - 36 = 0
⇒ (x - 12)(x + 3) = 0
Hence, x = 12 or - 3.
But x can not be negative.
So, x = 12 minutes.
Therefore, after 12 minutes both the container will have the same amount of water and the quantity is = 62 × 12 + 48 = 792 ounces. (Answer)
In this you could say 2.5L and 3.5L for total 6L. minus the 5L drunk and get about a liter left. in actuality:
x = 2.45 + 3.65 - 4.85 = 1.25
I would say that the estimation was reasonable.
in probability, it is equally as likely that a decimal lies between x and x.5 as it is for it to lie between x.5 and x+1. therefore when given a few numbers the rounding effect would likely round overall the same amount of points down as up. this would make it likely that the estimation would have on my an error within the amount rounded to. as you can see I rounded to 0.5 and the answer was half that
