Answer:
600 ft in one minute
i don't know if my answer is correct or not
Step-by-step explanation:
Object 1 280 ft/min => 85 m/min => 85/60 m/sec
sim.
Object 2320 ft/min => 98 m/min => 98/60 m/sec
when two bodies move in opp. direction there speeds are added
so
resultant speed is object 1 + object 2
the resultant comes out as 183/60 m/sec
time is given 1 minute
and we know Distance = time * speed
distance = 183/60 * 60 (183/60 is the speed and 60 is the time in sec as 1 min. = 60sec)
so the distance comes out as 183 m
convert it into ft
1m = 3.2 ft
so 600 ft in one minute
There are many ways to solve number 5 as it is just an reduce/enlargement of equidistant fractions
The first method that came up to my mind is just dividing denominators.
For A) you can do 72 divided by 18 which would give you 4. Then you can divide the given numerator with the answer you got from dividing the denominators. This would be 8 divided by 4 which would give you two. This means that 2/18 is equal to 8/72. You can check by simplifying the fraction. Both 2/18 and 8/72 equal 9 when simplified, therefore correct.
You can use this method for b, either use a calculator because of the decimals or just remove the decimals and replace them later. Make sure when you use this method, you are always dividing the bigger number. So in B you would do 40.3 divided by 12.4
The common difference is the constant that you get when you get the difference between any term and the one preceding it. In this case:
(3--4)=(10-3)=(17-10)=d=7
The answer will be 8 cause it’s counting by number
Answer:
True
Step-by-step explanation:
When sampling is done with replacement, then events are considered to be independent, meaning the result of the first pick will not change the probabilities for the second pick. Without replacement: When sampling is done without replacement, each member of a population may be chosen only once.
