Answer:
(-2,3)
Step-by-step explanation:
When you reflect a point across the y-axis, the y-coordinate remains the same, but the x-coordinate is transformed into its opposite (its sign is changed). Notice that B is 5 horizontal units to the right of the y-axis, and B' is 5 horizontal units to the left of the y-axis. the y-axis is the point (-x,y).
Answer:
22 inches
Step-by-step explanation:
Diameter=2×Radius
Radius=11
Diameter=11×2=22
Answer:
3 pounds
Step-by-step explanation:
12/4=3 (because we need to see how much bryant ate first)
12-3=9 (original - what bryant ate)
9/3=3 (what was left after bryant finish and what 1/3 of 9 is)
Answer:
So the answer for this case would be n=22547 rounded up to the nearest integer
Step-by-step explanation:
Let's define some notation
represent the sample mean
population mean (variable of interest)
represent the population standard deviation
n represent the sample size
represent the margin of error desire
The margin of error is given by this formula:
(a)
And on this case we have that ME =+1 and we are interested in order to find the value of n, if we solve n from equation (a) we got:
(b)
The critical value for 99% of confidence interval now can be founded using the normal distribution. The significance would be and the critical value , replacing into formula (b) we got:
So the answer for this case would be n=22547 rounded up to the nearest integer
