30=42+5x\implies 5x=-12\implies x=-\dfrac{12}5=-2.4

So a 30 year old professor would be 2.4 standard deviations less than the mean.

The graph of which function has an axis of symmetry at x = 3?
USPshnik [31]
You do this by converting to vertex form a(x - b)^2 + c   where the axis of symmetry  is x = b

the correct function to have a symmetry x = 3 will be the one which includes -6x
which is the last one 

x^2 - 6x - 1 =  (x - 3)^2 -9-1

the last option is the correct one

BlackZzzverrR [31]

Answer:

the answer is b(-7/4)

Step-by-step explanation:

2(x+5)-3=(2x=1)+1

2x+10-3=-(2x+1)+1

2x+7=-(2x+1)+1

2x+7-2x-1+1

2x+7=2x

2x+7-7+2x-7

x=-7/4

Terrance wants to earn a least a B in science. His scores so far are: 91,75,68,84 is it possible for him to earn a B
MaRussiya [10]

Hi,

As of right now it is not likely for him to get a B. This is because his average is 63.6% so unless he gets better scores, he's stuck with an F.

Help Please (n^2-6n+3) and -4n
Rina8888 [55]
-4n*(n^2 -6n +3)
= (-4n)*n^2 +(-4n)*(-6n) +(-4n)*(3)
= -4n^3 +24n^2 -12n . . . . . . . . . . . . corresponds to selection B

Note that the signs alternate. For the first question the signs of the answer are the reverse of those of the original trinomial.

For the second question, multiplying by -n changes the signs back to those of the original trinomial. Only one answer has the signs correct, selection A.
