Answer:
0.411^5 times 0.599
Step-by-step explanation:
0.599 chance of landing on heads.
0.411 chance of not landing on heads.
0.411 times 0.411 times 0.411 times 0.411 times 0.411 (for the 5 flips that do not land on heads) times 0.599 (for the time that it does land on heads).
The answer is C. because that is where the lines intersect, thus where the equations equal each other.
Answer: -4112
Step-by-step explanation:
Answer:
y = 90
Step-by-step explanation:
A direct variation is
y = kx where k is a constant
30 = k(-3) from the first set of points
30/-3 = -3k/-3
-10 = k
The equation is y = -10x
Let x = -0
y = -10 * -9
y = 90
Answer:
Center: (3,5)
Radius: 2
Step-by-step explanation:
x² + y² - 6x - 10y + 30 = 0
Put equation into center-radius form. First regroup terms:
(x²-6x) + (y²-10y) = -30
Complete the squares:
(x²-6x+3²) + (y²-10y+5²) = -30 + 3² + 5²
(x-3)² + (y-5)² = 4 = 2²
Center: (3,5)
Radius: 2
