Answer:

The statement is not reasonable.

Step-by-step explanation:

Josefina gave away 130% of her stamp collection.

We cannot give more than what we have.

lets understand it mathematically.

suppose i have x stamp.

according to question, i have to give 130% of my stamp collection

130% of x = 130/100 x = 1.3x

so, i have to given 1.3x stamp while i do have only x stamp which does not make any sense.

maximum i can give is x stamp.

x stamp in percentage of my total stamp collection which is also x will be

= x/x*100 = 100%

Thus, maximum one can give is 100% of what he has.

Thus, we can say that Josefina gave away 130% of her stamp collection is not reasonable.

You and your friend are playing a game where you spin a circular spinner with nine numbered sections of equal size. In this game

Phoenix [80]

Answer:

a) The subset consists of all the outcomes where your friend loses or there is a tie.

d) The subset consists of all the outcomes where you do not lose.

Both are correct.

Step-by-step explanation:

The subset A= { 1,3,4,6,7,9} removes 2,5 and 8 from the sample space of the game. Those three numbers are the ones for which your friend wins, therefore, the subset consists of all outcomes for which you either win (your friend loses) or there is a tie.

Checking the given alternatives, there are actually two correct ones. Alternatives a) and d) describe the same sample space (you not losing = your friend not winning).

Therefore, the two possible answers are:

a) The subset consists of all the outcomes where your friend loses or there is a tie.

d) The subset consists of all the outcomes where you do not lose.

Find the length of the third side of each triable 39 80

MArishka [77]

The Pythagorean theorem states:

$c^2=a^2+b^2$

where a and b are the lengths of the legs and c is the length of the hypotenuse of a right triangle.

Substituting with a = 80 and b = 39, we get:

$\begin{gathered} c^2=80^2+39^2 \\ c^2=6400+1521 \\ c^2=7921 \\ c=\sqrt[]{7921} \\ c=89 \end{gathered}$
