The numbers 1, 2, 3, 4,5, 6, 7, 8, 9 are arranged in a list so that each number is either greater than all the numbers that come
Nina [5.8K]

The lists of the numbers 1, 2, 3, 4, 5, 6, 7, 8, 9 that are possible is; 256

<h3>How to Solve Probability Combinations?</h3>

We are told that the last digit has to be either a one (1) or nine (9), then are two (2) options (>,<) for the remaining eight digits, so there are 2⁸ = 256 arraignments where each digit is either greater than or less than the preceding digits. This can be confirmed as below;

Numbers beginning with 1 = 8C0 = 1

Numbers beginning with 2 = 8C1 = 8

Numbers beginning with 3 = 8C2 = 28

Numbers beginning with 4 = 8C3 = 56

Numbers beginning with 5 = 8C4 = 70

Numbers beginning with 6 = 8C5 = 56

Numbers beginning with 7 = 8C6 = 28

Numbers beginning with 8 = 8C7 = 8

Numbers beginning with 9 = 8C8 = 1

Total lists of numbers possible = 1 + 8 + 28 + 56 + 70 + 56 + 28 + 8 + 1 = 256

GJ bisects ∠FGH and is a perpendicular bisector of FH.
Aleks04 [339]

Solution:

In \Delta FGH, As, given G J bisects ∠F G H and is a perpendicular bisector of F H.

So, F J=J H →→ G J is a perpendicular bisector of F H.

We will use angle bisector theorem to determine which statement is correct.

As, Angle bisector theorem states that , if a line segment bisects an angle, then the ratio of sides adjacent to angle, is equal to the ratio of two segments where the angle bisector cuts the third side.

So, \frac{GH}{GF}=\frac{HJ}{JF}\\\\ \frac{GH}{GF}=1\\\\ GH=GF

The option (C) which is the  \Delta F G H has exactly 2 congruent sides is true.

Did I choose the right graph?
Fudgin [204]

Answer:

Step-by-step explanation:

The - tells you that it is upside down. So that much of your choice is correct for certain.

The 1/8 squishes the graph something fierce. So of those graphs given, the one you chose is most likely correct. But you are right to be a little miffed at the question. You should never have to choose an answer with only a picture to guide you. If you have a graphing calculator, try y = -1/8 x^2 which is a good candidate for all the graphs.
