I am not sure, but I am sure that D is true
Step-by-step explanation:
Answer:
Option (d)
Step-by-step explanation:
From the given table,
Number of members in 1980 (t = 0) were 5400.
With the period of time number of members increased.
Let the number of years after 1980 = x
Therefore, line of best fit will be in the form of y = mx + b
Where b = Initial number of members = 5400
m = Increase in members in every 5 years duration
So the equation will be,
y = mx + 5400
From the given options,
Equation which matches to our equation is,
y = 310.58x + 5400
For the number of members in year 2022,
x = 2022 - 1980 = 42 years
y = 310.58(42) + 5400
y = 18445
Option (d) will be the answer.
Yes and it would give you 3,835 divided by 9
#5 is 5 days
40×5=200
200+150=250
20×5=100
100+150=250
Answer:
Step-by-step explanation:
Let the time taken by the john to get to his uncle be x.
Let the time taken by the john to get back from his uncle be y.
So,
x+y=12 ------ equation 1
According to the given velocities:
20x=30y
x=3/2y
Put the value x=3/2y in equation 1
3/2y+y =12
3y+2y/2=12
3y+2y=12*2
5y=24
y=24/5
y=4.8h
Now put the value of y in x=3/2y
x=3/2*4.8
x=14.4/2
x=7.2h ....
