Answer and Step-by-step explanation:
Notice that both these points are in the form of (x, y). "x" indicates that on the left-right axis (x axis), the point is x units away from the origin (0, 0). "y" indicates that on the up-down axis (y axis), the point is y units away from the origin.
In (4, 6), x = 4 and y = 6. This means that the point (4, 6) is 4 units to the right of the origin and 6 units up (see red dot on attachment).
In (6, 4), x = 6 and y = 4. This means that the point (6, 4) is 6 units to the right of the origin and 4 units up (see blue dot on attachment).
As can be seen, these two points do NOT coincide, so they are different.
Answer:
A circle is centered at the point (-3,2) and passes through the point (1,5). The radius of the circle is (5 ) units. the point (-7, -1) and point (-7, 5) lies in this circle.
Step-by-step explanation:
equation of circle is
(X-center_X)^2 + (y-center_Y)^2 = r^2
==> (x+3)^2 + (y-2)^2 = r^2
Now it passes 1,5 so
4^2+3^2 = 5^2
==> r = 5
when x = -7
y = -1 or 5
Answer:
Step-by-step explanation:
We define X the random variable that represent the heights of a population for ten year old children, and for this case we know the distribution for X is given by:
Where 
and 
We want to find this probability:
We can use the z score formula to solve this problem given by:
Using this formula we have:
And we can find this probability with this difference
We can use tables for the normal standard distribution, excel or a calculator and we got this
Answer:
K-273=C
Step-by-step explanation:
K=C+273
Subtract 273 from each side
K-273=C+273-273
K-273=C
