Answer:
Step-by-step explanation:
can be factored out as (-x-6)(x-6)
x-intercepts are: +6 and -6
represents the two ends of the rainbow
y-intercept: y=36
represents the highest point of the rainbow
You need to know these two formulas:
For example,
Regular Pirce = $80.
Discount = 20%
Discount = 20% x $80 = 0.2 x 80 = $16
Sale Price = 80 - 16 = $64
----------------------------------------------------
Answer: The Sale Price is $64.

He took 36 weeks to compose 12 songs.

Answer:
Probability to get tails exactly 8 times or exactly 5 times is 0.29
Step-by-step explanation:
No of ways the coins lands tails exactly 8 times
P(8) = 15C8 × ×
No of ways the coin lands tails exactly 5 times
P(5) = 15C5 × ×
Probability to get tails exactly 8 times or 5 times
P(8)+P(5) = 15C8 × + 15C5 ×
P = ( 15C8 + 15C5 )
P = ( ( ) + ( ) )
P = ( 6435 + 3003 )
P = ( 9438)
P = ( 4719)
P =
P = 0.29
