Call the mystery fraction ' F ' (for 'fraction').
12 is the mystery fraction of 30 .
12 = F x 30
Divide each side by 30 : F = 12/30 = 2/5 .
Answer:
Step-by-step explanation:
The best option is for the consultant to remove these data points because they are outliers. Unusual data points which are located far from rest of the data points are known as outliers.
Answer:
- Fresh Pond: p(t) = 854 +3t
- Strawberry: p(t) = 427·1.10^t
Step-by-step explanation:
(a) The general term of an arithmetic sequence is ...
an = a1 + d(n -1)
If we let the sequence of population numbers be modeled by this, and we use t for the number of years, we want n=1 for t=0, so n = t+1 and we have ...
p(t) = 854 +3(t+1-1)
p(t) = 854 +3t
__
(b) The general term of a geometric sequence is ...
an = a1·r^(n-1)
were r is the common ratio. Here, the multiplier from one year to the next is 1+10% = 1.10. Again, n=t+1, so the population equation is ...
p(t) = 427·1.10^(t+1-1)
p(t) = 427·1.10^t
Answer:
40 * x - 600 = 0
Step-by-step explanation:
The first thing is to identify the variable (x) of the equation and they will be the number of days that Leilah will take to read her flashcards. Now if you need to study 600 out of 2400, it is because you have read 1800. Therefore we have to:
2400 - 1800 = 40 * x
rearranging
40 * x - 600 = 0
The above would be the equation of the situation
Answer:
The mass of the block is 
Step-by-step explanation:
we know that
The density is equal to the mass divided by the volume
