Answer:
Null hypothesis:
Alternative hypothesis:
And based on this the best option for this case is:
Ha: μregular > μspecial H0: μregular = μspecial
Step-by-step explanation:
For this case the interest is verify if the true average amount of warpage for that laminate is less than for the regular laminate.
Let's put notation:
represent the true mean for the amount of warpage for the regular laminate
represent the true mean for the amount of warpage for the special laminate
And based on the claim, the correct system of hypothesis are:
Null hypothesis:
Alternative hypothesis:
And based on this the best option for this case is:
Ha: μregular > μspecial H0: μregular = μspecial
Answer:
x= -2, x= +11
Step-by-step explanation:
I hope this is right!
To factorise, we need two numbers that add to make -9 and multiply together to make -22.
2 - 11 works, so we put it in the brackets in this order.
(x + 2) (x - 11)
so x + 2 = 0 and x - 11 =0
but we could also simplify this to say that x could be either -2 or + 11.
I hope this helps.
Have a lovely day.
