Answer: 
Step-by-step explanation:
The quadratic equation in its standard form is:

Now, we are given 5 points of the parabola (if you graph a quadratic equation you will have a parabola), however we only need to choose three points to find the coeficients
,
and
in the quadratic equation.
So, let's choose the first three points:
(-1,14):

(1)
(0,7):

(2)
(1,4):


(3)
Substituting (2) in (1) and (3):
(4)
(5)
At this point we have a system with two equations.
Adding (4) to (5):
(6)
Isolating
:
(7)
Substituitng (7) in (3):
(8)
Isolating
:
(9)
Now we have the three coeficients and we can write the quadratic equation:

Answer:
p ≥ -10
Step-by-step explanation:
first, subtract one from each side to get:
p/5 ≥ -2
lastly, multiply each side by 5
p ≥ -10
Answer:
6x +3w
Step-by-step explanation:
3(2x + w)
Distribute
3*2x +3*w
6x +3w
Answer:
A
Step-by-step explanation:
B,.C and D are wrong because
B states all. The hypothesis stated above does not mention all samples
.
C. Mentions a mean. Per the hypothesis, the percentage of defective screens was an actual number and not a mean.
D. The question is not referring to a standard deviation
