Well, for number 15, this is what I came up with, I hope it is what your teacher is looking for: 
So it starts out with 3 butterflies, and it doubles every minute: 
3x2 = 6  That is for the first minute 
6x2 = 12 That is for the second minute 
12x2 = 24 That is for the third minute 
24x2 = 48 That is for the fourth minute

So, It asks for using the power of 2 in your answer, that is what I came up with for part A. 

For part B I would say something like this: 

X represents the number of butterflies left. 
The equation, using the information above would be this:

48-7 = X
Then simplify, which would leave you with 41 butterflies. 

I hope this helps! :)

Answer:

6:

S1: 8 = 11x + 8

S2: 0 = 11x

S3: x = 0

8:

S1: 6x = 2x + 24

S2: 4x = 24

S3: x = 6

Step-by-step explanation:

6:

S1: Add like terms (5x+6x)

S2: Subtract 8 from both sides to get x by itself

S3: divide by 11 (anything that divides/is divided by 0 is 0)

8:

S1: Add 7 to the other side

S2: Subtract 2x to the other side

S3: divide 24 by 4

Sales prices of baseball cards from the 1960s are known topossess a skewed-right distribution with a mean sale price of $5.25and
Serga [27]

Answer:

c. Skewed-right with a mean of $5.25 and a standard error of$0.28

Step-by-step explanation:

As we have given that Sales prices of baseball cards have a right-skewed distribution with a mean $5.25 and a standard deviation is $2.80.

Now, We know that if standard deviation = σ

then, standard error = \frac{\sigma}{\sqrt{n}}

As, we have standard deviation = $2.80

then standard error will be \frac{2.80}{\sqrt{100}}

⇒ Standard error = $0.28

Hence, Option (c) is the correct option.
