Answer:
Step-by-step explanation:
if r=1 perfect positive correlation.
if r=-1 ,perfect negative correlation.
r=0 ,no correlation.
r=.02 ,so D
Answer:
Square pyramid
Step-by-step explanation:
A square pyramid is a solid consisting of a square, a point not in the same plane as the square, and all points between them.
It can't be these
Triangle means the plane of the figure that is formed by connecting 3 particular points but it is not in a straight line. (B)(B) ← incorrectincorrect
Cube means the solid figure of having 6 square plane faces which that the angle between about 2 adjacent sides that is a right angle (C)(C) ← incorrectincorrect
Square Prism means the shape of a square that has approximately 3 dimensional shape that has a rectangular sides and shape, but it has about 2 that are square(D)(D) ← incorrectincorrect
Your answer is ↓
square pyramid (A)(A) ← CORRECT!CORRECT!
Good luck on your assignment and enjoy your day!

the polynomial remainder theorem states that the remainder of the division of a polynomial f(x) by a linear polynomial x-r is equal to f(r). In particular, x-r is a divisor (= a factor) of f(x), if and only if f(r)=0.
first we are dividing by x - 2.
so, r = 2.
as this is a factor, the remainder must be 0.
so,
0 = f(2) = 2³ + a2² - 15×2 + b = -22 + 4a + b
22 = 4a + b
then we divide by x + 3.
so, r = -3.
and the remainder is 75.
so,
75 = f(-3) = (-3)³ + a×(-3)² - 15×-3 + b = 18 + 9a + b
57 = 9a + b
now we have 2 equations with 2 variables to solve.
and since one term (+b) is the same in both equations, we use a little trick to subtract the first from the second equation.
57 = 9a + b
- 22 = 4a + b
---------------------
35 = 5a + 0
a = 7
22 = 4×7 + b = 28 + b
-6 = b
a = 7
b = -6
Answer:
There is a very high possibility that a green ball will be taken out of the bag. The total amount of balls in there are 14.
8 of the 14 balls are green so the answer is 8/14
