What points are on the graph ( the function is y=-x^2+12)

1 answer:

3 0

Y=-x²+12

This is a parabola opening downward because the coefficient of x² =1 >0

The domain (the value of the input of x) is all real numbers.

to find some points (& you can extend to 1,000,000 points) that are on the graph, replace x by any value & you'll find the related value of y

Example:
f(1)= 1²+12 = 13 ==> for x=1 y=13 & this points ∈ to the parabolas
f(2) = 2²+12 =16 ===> for x=2, y=16) this points ∈ to the parabolas
and so on & so forth

Why did the delegates make changing the constitution so difficult?

erma4kov [3.2K]

The Constitution is difficult to amend because it requires a supermajority of either members of Congress or a supermajority of state legislatures to propose a new amendment for ratification. Even after acquiring the requisite two-thirds of either group to propose the amendment, it then has to be ratified by 75 percent of the states, either by their legislatures or state Constitutional conventions

You question is of two parts.
For the first part:
A group of men and women were asked what their favorite pet was, and the results of the survey were tabulated.

$\begin{center}
\begin{tabular}
{|c|c|c|c|c|}
 & Cats & Dogs & Other & Total \\ [1ex]
Male & 42 & 58 & 6 & 106 \\
Female & 52 & 48 & 2 & 102 \\ [1ex]
Total & 94 & 106 & 8 & 208
\end{tabular}
\end{center}$

Let event A be defined as randomly choosing someone who picked cats or dogs as their favorite pet. Let event B be defined as a randomly chosen person being male.
Find P(B| NOT A).

P(A) = P(choosing cat) + P(choosing dog) = $\frac{94}{208} + \frac{106}{208} = \frac{200}{208} = \frac{25}{26}$
P(NOT A) = $1- \frac{25}{26} = \frac{1}{26}$
P(B and NOT A) = P(males that did not choose cat or dog) = $\frac{6}{208} = \frac{3}{104}$

P(B | NOT A) = $\frac{P(B \, and \, NOT \, A)}{P(NOT \, A)} = \frac{ \frac{3}{104} }{ \frac{1}{26} } =\frac{3}{104}\times26= \frac{3}{4}$

For the second part of the question.
Petey is considering investing $19 in a certain company. Financial advisors forecast that there is a 30% chance that the stock will increase in value by 10%, and a 70% chance he will lose his initial investment. Determine if Petey should make the investment, and find the expected value of the investment.

If his investment increases by 10%, the value of the investment will be 1.1 x $19 = $20.90 with a probability of 30% or 0.3

The expected value of the investment is given by
$\$20.90\times0.3+(-\$19\times0.7)=\$6.27-\$13.30=-\$7.03$

Therefore, Petey should not make the investment as there is an expectation of a loss from the investment.
