Answer:

c The expansion of (x + y)^6 will yield 7 terms

Step-by-step explanation:

(x + y)^6 =

x^6 +6x^5y + 15x^4y^2 + 20x^3y^3 + 15x^2y^4 + 6xy^5 + y^6

so its a no on A

its a no on B because its missing a 20

its a yes on c

its a no on d because the sum is 6

so c

GIVING 100 POINTS FOR THESE 3 PROBLEMS

mart [117]

Answer:

Step-by-step explanation:

$A=\frac{a+b}{2}*h=\frac{4+7}{2}*3=16.5cm^2$

$A=\frac{ab}{2} =\frac{4*6}{2} =12in^2$

$A=wl=6*5=30in^2$

$12+30=42in^2$

$A=\frac{a+b}{2}h=\frac{28+40}{2}*30=1020ft^2$

Wall = A= $\frac{ab}{2} =\frac{6*30}{2}=90ft^2$

What are the values of a, b, and c in the quadratic formula given the equation 2x^2 + 6x= -8 ?

AlladinOne [14]

It should be written in the form ax²+bx+c=0,
so you meed to move -8 to the left side
2x²+6x+8=0
the number in front of x² is a
the number in front of x is b
the number without x is c,
so a=2, b=6,c=8

inysia [295]

Answer:

B. There is sufficient evidence that the mean of the pressure required to open a certain valve has changed.

Step-by-step explanation:

We make this conclusion based on these reasons:

We are told that the "null hypothesis was rejected" after the "manager feels that the pressure variability has changed., meaning the null hypothesis was the opposite of what occurred; that is to say, it is the alternate hypothesis that proved true instead.
"changes in the manufacturing process" form what can be called "sufficient evidence" that the mean of the pressure required to open the valve has changed, thereby going against the null hypothesis.

It is based on the above reasons that the null hypothesis was rejected.
