25,600 will be the bacteria population after doubling every 30 minutes for 3 hours.
Answer: 3/10 bucket will fill the barrel completely
Step-by-step explanation: If 1/5 of the bucket is 2/3 then we want to find 1/3 of 1/5 and multiply it by 3 to find the whole of the barrell 3/3 so 1/5 divided by 2 is 1/10 and multiplied by 3 is 3/10. In math form its 1/5=.2 so .2 divided by 2 is .1 and multiplied by 3 is .3 which also equals 3/10
Answer:
Lcm=18
Step-by-step explanation:
First do prime factorization of 6 and 9
common factor of 6 is 3
and remaining factor is 2×3
Now,
C.F×R.F= 3×2×3
=18
Answer:
Mean = 78 ;
Standard deviation = 14
Step-by-step explanation:
Given that:
Mean score = 68
Standard deviation = 14
When a constant value is added to the individual value of a dataset, the new mean value will become the sum of the initial mean value and the constant term added to the values.
Constant Added score = 10
The mean of scaled test score will be:
Mean score + constant added score
68 + 10 = 78
The standard deviation remains unchanged ; Hence, standard deviation = 14
4/5th's of an hour would be the answer.
