Answer:
C. n=23; p^=0.5
Step-by-step explanation:
Normal distribution is symmetrical about the mean.
So, p should be close to ½
Answer:

Step-by-step explanation:
So we have the equation:

Add 2 to both sides. The left cancels:

Divide both sides by 6. The left cancels:

So, the value of x is -1.
And we're done!
The answer is B) -x^2-3
This is because you have an exponential graph that is flipped, hence the negative sign, and down 3.
$30 • 10%
10% = 0.10
30 • 0.10 = 3
The answer is $27. They got $3 off.
$30 - $3 = $27.
I had the similar test and got it right so it should be B
