It is like if you have two number lines. Then one has a pointer at 0, and the other one has the pointer facing at 2 then it will be lesser because the first one has 0 or if it turned around it would be greater. If it is equal then it would have the same number, but watch out if it is a negative number.
Answer:
C) P (X2 ≤ 8.2) = 0.96
Step-by-step explanation:
P value for the test is the probability of obtaining results that have been observed in the null hypothesis statement. A very small value of p indicates that there is unlikely chance of null hypothesis being true which means that we cannot accept null hypothesis based on the small p value.
Answer:
-27/5 or -5 2/5
Step-by-step explanation:
Simplify
1 2/7 to 9/7
-4 1/5 to -21/5
multiply together
(9)(-21)/(7)(5)
-189/35
u can simplify by diving by 5 to get
-27/5
we can see that the center is (-3, 3) and the radius is 9 units.

How to find the center and radius of the circle?</h3>
The general circle equation, for a circle with a center (a, b) and radius R is given by:
(x - a)^2 + (y - b)^2 = R^2
Here we have the equation:
x^2 + y^2 + 6x = 6y + 63
Let's complete squares:
x^2 + y^2 + 6x - 6y = 63
(x^2 + 6x) + (y^2 - 6y) = 63
(x^2 + 2*3x) + (y^2 - 2*3y) = 63
Now we can add and subtract 9, (two times) so we get:
(x^2 + 2*3x + 9) - 9 + (x^2 - 2*3x + 9) - 9 = 63
(x + 3)^2 + (y - 3)^2 = 63 + 9 + 9 = 81 = 9^2
(x + 3)^2 + (y - 3)^2 = 9^2
Comparing with the general circle equation, we can see that the center is (-3, 3) and the radius is 9 units.

Answer:
for a. you will first solve 5x²-2x+6 with
x=-b ± ✓b²-4ac
----------------
2a
then put the two answers you will get into a bracket then multiply it with 1/2x - 1\4
then write in form of dis :- A ×10^n
Step-by-step explanation:
b. the two products are not the same
