Answer:
90
Step-by-step explanation:
Length times with times height
Answer:
-21
Step-by-step explanation:
-3 * 7
Step 1:
a) Write the quadratic model
a = -15.64
b = -1.24
c = 5.23

b) t = 0.30

c) t = 0.52 seconds

d) 0.30 is more likely to be relaible.
e)
(a) P( fifth one is bad) = P( first 4 are OK) * P(5th is bad)
= (0.98)^4 * 0.02 = 0.0184 or 1.84%
(b) this will be (0.98)^10 = 81.70%
Not sure what x' means but
seems to be the reverse distributive property
normally written as
a(b+c)=ab+ac
we can see the similarity
a(x'+y)=ax+ay
distributive property
