Answer:
Step-by-step explanation:
area=π r²
=π×15²
=225 π cm²
Given:
In a parallelogram ABCD, AB=(9x-14) inches and DC=(3x+4) inches.
To find:
The measure of DC.
Solution:
We know that opposite sides of a parallelogram are equal.
In the parallelogram ABCD, AB and DC are opposite sides. So,
Divide both sides by 6.
Now,
inches
inches
inches
inches
The measure of DC is 13 in.
Therefore, the correct option is C.
( 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: B, D, E
Step-by-step explanation:
Statement 1 cannot be true because f(1)<0.
Statement 2 might be true.
Statement 3 cannot be true because if f is continuous, then for some value between -1 and 0, f(x) is positive by the Intermediate Value Theorem.
Statement 4 might be true.
Statement 5 might be true
