Planet A: Jupiter
778,600,000km from the sun
Planet B: Neptune
4,495,100,000km from the sun
Planet C: Saturn
1,433,500,000km from the sun
Planet D: Uranus
2,872,500,000km from the sun
Answer:
3
Step-by-step explanation:
area = side length times side length
therefore x * x = 9
therefore x^2 equals 9
square root both and x = 3.
A) The area of a square of side 1 that is outside a circle of radius 1 is (1 -π/4), so the probability of interest is
.. p(outside unit circle) = 1 - π/4
b) The sets of numbers such that 3y>x is fill an area that is 5/6 of all sets of numbers (x, y) in the interval [0, 1].
.. p(3y > x) = 5/6
Answer:
E. The sample size is the same for X and Y, and the confidence level used for the interval constructed from X is greater than the confidence level used for the interval constructed from Y
Step-by-step explanation:
Confidence interval formula is given as
CI = \bar{x} \pm z*(\sigma/\sqrt{n})
Here, we can see that the width of confidence interval is z*(\sigma/\sqrt{n}) , which is dependent only on z critical value, standard deviation (sigma) and sample size (n)
This simply entails that either z or n or both are greater for x as compared to y.
Option E is correct answer because x and y can have sample sizes, but if the z critical is greater for x, then the width will be larger.
