Answer:
Step-by-step explanation:
P(2 heads) = P(first flip = head)*P(second flip = head)
=> 
= 
P(1 head) = P(first flip = head)*P(second flip = tail) + P(first flip = tail)*P(second flip = head)
= 
P(no heads) = P(first flip = tail)*P(second flip = tail)
=

y-interceptAnswer:
x=0, y=1
x=1, y=5
Step-by-step explanation:
slope is 4
y intercept is (0,1)
Step-by-step explanation:
By Factor Theorem, we have:
(x - 1)(x - 2)(x - 3)(x + 3)
= (x² - 3x + 2)(x² - 9)
= x⁴ - 3x³ - 7x² + 27x - 18.
Answer:
x=29. Angle C= 93
Step-by-step explanation:
3(x+2)= 3x+6.
3x+6+52+35= 3x+93.
180-93=87.
87/3= 29. So that means x=29.
for proof you can do 3(29)+93 and you'll get 180.
For angle C; 3(29+2)= 3x31. 31x3= 93.
Angle C= 93 degrees.
Answer:
20% chance
Step-by-step explanation:
20 is the whole
5 times 20 is 100
5% = 1 ticket
5% times 4 is 20%
