Cash is always king. It will cost you more if you pay interest, but you may not have enough money to buy this very over priced $13,499 TV. I say shop around for a cheaper TV.

question number 36 the answer is always true because rational numbers are numbers that can be turned into fractions or simple fractions easily and any integers that is positive added together will provide a positive answer.

37. the answer is always true because and a negative integer and a negative integer added together will give a negative answer.

38. sometimes true. a positive intergee plus a negative interger can give a positive or negative answer. eg -3+2=-1 but -4+8=4

39. always true. + multiply + =+

40. never true. - multiply - = +

The formula κ(x)= f′′(x) 1+f′(x)23/2 expresses the curvature of a twice-differentiable plane curve as a function of x. Use thi

Katyanochek1 [597]

Answer:

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Step-by-step explanation:

considering the Given function

F(x) = $-5x^2$

first Determine the value of F'(x)

F'(x) = $\frac{d(-5x^2)}{dy}$

F'(x) = -10x

next we Determine the value of F"(x)

F"(x) = $\frac{d(-10x)}{dy}$

F" (x) = -10

To find the curvature function we have to insert the values above into the given formula

K(x) $= \frac{|f"(x)|}{[1 +( f'(x)^2)]^{\frac{3}{2} } }$

K(x) = $\frac{-10}{[1 + (-10x)^2]^{\frac{3}{2} } }$ ( curvature function)

Answer:

A. The true proportion is within 3% of her estimate, with some degree of confidence.

Completed question:

A TV newscaster reports the results of a poll of voters, and then says, "The margin of error is plus or minus 3%." Explain carefully what that means.

A. The true proportion is within 3% of her estimate, with some degree of confidence.

B. The proportion of the population who voted for one candidate is 3% less than the percent of the population who voted for the other candidate.

C. The sample proportion is within 3% of her estimate, with some degree of confidence.

D. It means that 3% of the polls are invalid.

Step-by-step explanation:

Margin of error can be defined as the maximum expected difference between the true value of a parameter and the estimated value.

In the case above, a tv newscaster reports the results of a poll of voters, and then says, "the margin of error is plus or minus 3%", according to the definition of margin of error, the maximum expected difference between the true proportion and the estimated proportion is 3%. Which means that the true proportion is within 3% of her estimate, with some degree of confidence

Solve for x <br> 7/9(6 − 36) + 9 = 23

Leona [35]

Simple...

you have:

$\frac{7}{9} (6-36)+9=23$

$\frac{7}{9} (-30)+9=23$

$-23 \frac{1}{3} +9=23
$

We can immediately see this is false.

Thus, your answer.
