The answer to the question is (2,-2)
Answer:
6 ounces of oil
Step-by-step explanation:
Well the first salad dressing is probably 8 ounces because 2+6 = 8
Then we must find out how large this recipe compares to the original
24/8 = 3
So we need all the ingredients to be tripled to keep the same ratio of 2:6
The new dressing has 2*3 ounces of oil and 6*3 ounces of vinegar
which equals 6 ounces of oil and 18 ounces of vinegar.
Hope this helps!

( a ) The null hypothesis, represented by 
, should be equivalent to 0.6 pounds per square inch, considering it normally is predicted to be equivalent to the population parameter, which, in this case, is 0.6 psi ( pounds per square inch. ) The alternative hypothesis on the other hand contradicts the null hypothesis, and as the manager feels the pressure has been reduced, the alternative hypothesis points that the pressure is less than 0.6 psi -
<em>stigma is represented by the sign ( σ )</em>
( b ) Now if you were to reject the null hypothesis when true, that would lead to a type I error. That would mean that to reject the fact that σ = 0.7, and accept that σ < 0.7, even though σ = 0.7 is true, would make a type I error.
_______
( c ) A type II error is quite the opposite. Accepting the null hypothesis while rejecting the alternative hypothesis would make a type II error.
Answer:
If the conclusion is false, then one or more of the premises must also have been false.
Step-by-step explanation:
One important distinguishing feature of valid arguments is that - if the conclusion is false, then one or more of the premises must also have been false.
An argument form is said to be valid, if and only if, when all premises are true, then the conclusion is true.
