Use the distance formula:
x2 is 1 and x1 is -2
y2 is root7 and y1 is 0
Point (X1,Y1) is basically the coordinate of the centre point of the circle
Point (X2,Y2) is the point that on the circle
So if the point(1,root7) is on the circle, the final distance you get should be the radius of the circle, which is 4 units
Calculate it and you can get the answer that is 4
Therefore the point (1,root7) is on the circle
Answer:
No, because z-statistics lies within the critical region.
Step-by-step explanation:
The z value is calculated to determine whether the null hypothesis should be accepted or rejected. The null hypothesis is rejected when the z-value lies outside the critical region. The critical region is determined by the sample data.
Answer:
f-1(x) = √x. +5
Step-by-step explanation:
f(x) = (x-5)^2
x = (y-5)²
√x = y-5
√x +5 = y
3/4 of 200 is 150, so 155/200 is bigger than 3/4
