Answer:Its been 5 hours. so 85 - 82 = X. X times 0.6 = 5 then translate to 5 hours.
Step-by-step explanation:
<span>In real world variables can be used to represent variable quantities in situations and in patterns.
Example: fishing. When we are fishing and we catch a fish, the fish can be represented with a variable. </span><span> It is particular fish, and we know some facts (the fish swims, it has gills, its size) , but we do not know other details about the fish (exactly which type of fish it is).</span>
48 marks. Because 80/10 is 8. 8x6 =48
Answer: Bradley would expect 94 times to get a blue or green gumball.
Step-by-step explanation:
Since we have given that
Number of blue gumballs = 15
Number of yellow gumballs = 12
Number of green gumballs = 2
Number of purple gumballs = 16
Total number of all gumballs = 45
Probability of getting either a blue gumball or green gumball be
So, Expectation of getting a blue gumball or green gumball if a gumball was taken out 250 times :
Since we know that it must be less than 94.4.
So, the nearest smallest integer will be 94 times .
Hence, Bradley would expect 94 times to get a blue or green gumball.
Use pythagoras.
sqrt((6--12)^2 + (8--4)^2) = 6*sqrt(13) = 21.63 (2 d.p.)
