Step-by-step explanation:
blank I don't see a shape
Answer:
Rectangle
Step-by-step explanation:
Well if point A is on (2,3) and you reflect it over the x axis point B would be located at (2,-3).
Then over the y axis point C would be located at (-2,-3), then reflecting that over the x axis point D is (-2,3)
<em><u>Points</u></em>
__________
A. (2,3)
B. (2,-3)
C. (-2,-3)
D. (-2,3)
__________
So graphing all these points we get a rectangle.
Because it has 4 sides that are 90 degrees and the sides opposite from each other are the same.

Answer is D on e2020
Step-by-step explanation:
why does vla statistics have little to no answers available for it?
We are given the following data:
Sample Size = n = 1000
Sample Mean = u = 15 hours
Population Standard Deviation = s = 2 hours
Since we know the population standard deviation, we can use z distribution to find the confidence interval about the mean. z value for 95% confidence interval is 1.96.
Formula for the confidence interval is:

Using the values in the formula, we get:

Therefore, the 95% confidence interval about the population mean is 14.88 hours to 15.12 hours. So B option is the correct answer.
Answer: 16/25 (sorry I'm not really sure bc I'm just a middle schooler)
Step-by-Step explanation:
2 2/5 km=2.4 kilometers
3 3/4 minutes=3.75 minutes
2.4/3.75=240/375
240/375=48/75=16/25=64/100=0.64
0.64 km/minute (0.64 km per minute)
you can solve the problem using the fractions...
2 2/5=12/5
3 3/4=15/4
(12/5)/(15/4)=(12/5)*(4/15)=48/75=16/25=0.64 again, or you can simplify before multiplying...
(12/5)/(15/4)=(12/5)*(4/15)=(4/5)*(4/5)=16/25...
