Answer:
Check the explanation
Step-by-step explanation:
From the given differences of SAT scores
find the mean and standard deviation of difference.
Kindly check the attached image below to see the step by step explanation to the question above.
Given function : 
We need to identify a " initial amount", b "growth factor", r " rate of growth".
We know, exponential growth formula
, where a is initial amount, b is growth factor. On comparing with given function let us find values of a and b.
⇔
.
We can see a= 1.05 and b = 1.46.
Now, b=1+r.
Therefore, 1+r =1.46.
Subtracting 1 from both sides, we get
1+r-1 =1.46-1
r = 0.46.
On converting 0.46 into percentage, we get
0.46 × 100 = 46.
Therefore, intial amount a = a= 1.05 , growth factor b = 1.46, and the rate of growth r= 46%.
Answer:
27
Step-by-step explanation:
3 : 8 cannot be simplified into integers
neither can 6 : 11
because decimals are not integers
so 3 + 8 + 6 + 11 = 27
Im not sure why there are two b's so I added both of them
if you dont need both b's then the answer is 25
