Check the picture below.
you can pretty much just count the units off the grid.
A polynomial can only have one constant, since the constant is the one number being added or subtracted from the rest of the polynomial, and it is the only number that is not being multiplied by an x value.
When testing the differences between means, the null hypothesis suggests that any observed difference is due to random error.
What is hypothesis testing?
Hypothesis testing is a form of interference that uses data from a given data set or sample to derive meaningful results or conclusions about population distribution.
What is a Null hypothesis?
A null hypothesis is a type of assumption in statistics that proposes that for a given set of data or observations, there is no statistical significance or it shows that there is no difference.
It is a quantitative analysis. It is denoted by H0.
What is mean?
The mean is the average for a given number of samples in the sample solution. The mean can also be derived from the normal distribution graph.
Hence when testing the differences between means, the null hypothesis suggests that any observed difference is due to random error.

#SPJ4
Answer:
A, D, F
Step-by-step explanation:
A. True, because represents quadratic function (the greatest power of x is 2)
B. False, because this function is quadratic, so cannot be linear
C. False. The vertex of the parabola is at point (-7,4) (see diagram)
D. True. The axes of symmetry is the line x=-7 that passes through the vertex.
E. False. The y-intercept is at point x=0 and
F. True. The graph has the maximum at vertex, where
G. False. The graph of the parabola intersects the x-axis at two points (-9,0) and (-5,0), so x=-9 and x=-5 are two real solutions of the equation f(x)=0.
Answer:
w = -8
Step-by-step explanation:
Solve for w:
5 (w + 2) - 8 w = 34
5 (w + 2) = 5 w + 10:
5 w + 10 - 8 w = 34
Grouping like terms, 5 w - 8 w + 10 = 10 + (5 w - 8 w):
10 + (5 w - 8 w) = 34
5 w - 8 w = -3 w:
-3 w + 10 = 34
Subtract 10 from both sides:
(10 - 10) - 3 w = 34 - 10
10 - 10 = 0:
-3 w = 34 - 10
34 - 10 = 24:
-3 w = 24
Divide both sides of -3 w = 24 by -3:
(-3 w)/(-3) = 24/(-3)
(-3)/(-3) = 1:
w = 24/(-3)
The gcd of 24 and -3 is 3, so 24/(-3) = (3×8)/(3 (-1)) = 3/3×8/(-1) = 8/(-1):
w = 8/(-1)
Multiply numerator and denominator of 8/(-1) by -1:
Answer: w = -8
