The number of defective modems in the inventory is 20%⋅ 30 + 8%⋅ 50 = 10 (out of 80).
Note that the number of defectives in the inventory is fixed, i.e., we are not told that there
is 1
8 probability that a modem in the inventory is defective, but rather that exactly 1
8
of
all modems are defective. The probability that exactly two modems in a random sample
of five are defective is = 0.102
D varies directly with t means
d=kt
105=3k
divide both sids by 3
35=k
d=35t
when t=8
d=35(8)
d=280

Answer:
the answer to your question is U=2
Step-by-step explanation:
Answer:
20700 feet per hour
Explanation:
Convert 345 feet per minute to 345 feet per hour.
First find how many minutes are in an hour:
60 minutes = 1 hour.
1 minute • 60 = 1 hour
345 feet • 60 = 20700 feet per hour.
I believe for the first part x would equal -2 and y would equal -1
hope this helps!
