Answer:

Step-by-step explanation:
Given the expression


Apply distributive law


so the expression becomes

∵ 




Therefore,

The event space of getting exactly one tail is {HT, TH}
The sample space is {HH, HT, TH, TT}
There are two ways to get exactly one tail, out of 4 total possible outcomes.
So 2/4 = 1/2 is the answer
Answer:
1) 4100
2) 45000
Step-by-step explanation:
Answer:
volume of old tank=20×4×10=800m³
no of shark adjust =800/25=32 sharks is adjusted in old shark tank
for new
if length=25℅0f 20+20=25m
breadth=25%of 4 +4=1+4=5m
height is same=10m
new volume =25×5×10=1250m³
total no.of shark adjust=1250/25=50 shark
50-32=18 more shark that the new tank hold.
Answer:
x=1
Step-by-step explanation
:−5x=−2x−3
Step 1: Add 2x to both sides.
−5x+2x=−2x−3+2x
−3x=−3
Step 2: Divide both sides by -3.
−3x
−3
=
−3
−3
x=1
