A popular game requires the player to select the same five numbers out of a set of allowed numbers that will be drawn at random

by the lottery commission. For the next game, if you select the five numbers that won in the most recent prior drawing, your chances of winning will:

Options:

A.) decrease because the same five numbers are not likely to occur again so soon.

B.) Increase because those five numbers must be lucky.

C.) be unaffected because every set of five numbers is equally likely on every attempt.

D.) be unknown because it depends on how many times those five numbers have won in the last several drawings.

Answer:

be unaffected because every set of five numbers is equally likely on every attempt.

Step-by-step explanation:

Number selection in the lottery is randomized with each set of number having equal chances of being selected. This means that each and every selection attempt is independent and the outcome of each attempt does not depend on any prior outcome or event. This means that if the numbers drawn from the most previous prior drawing are selected on the next attempt, the probability of winning on the next attempt Neither increases nor decreases. Hence , the probability of winning on the next attempt with this selection is unaffected.

Answer:

y-1=\frac{1}{8}\left(x-7\right) is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

Step-by-step explanation:

The endpoints:

  • B(6,9)
  • C(8,−7)

Calculating the Midpoint M of BC:

\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)

\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)

The Midpoint M of BC =\left(\frac{8+6}{2},\:\frac{-7+9}{2}\right)

                                     =\left(7,\:1\right)

Calculating the slope of BC:

\mathrm{Slope\:between\:two\:points}:\quad \mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}

\left(x_1,\:y_1\right)=\left(6,\:9\right),\:\left(x_2,\:y_2\right)=\left(8,\:-7\right)

m=\frac{-7-9}{8-6}

m=-8

Given a line with slope m then the slope of a

line  perpendicular to it is:

m_{prependicular}=-\frac{1}{m}=-\frac{1}{-8}=\frac{1}{8}

Equation of line using point-slope form

y-y_1=m\left(x-x_1\right)

y-1=\frac{1}{8}\left(x-7\right)        

     

Therefore, y-1=\frac{1}{8}\left(x-7\right) is the equation in point-slope form for the perpendicular bisector of the segment with endpoints B(6,9) and C(8,−7).

What numbers multiply to equal -9 but add up to 12?
Elan Coil [88]
I don't think this is possible.

The factors of -9 are:
-1 x 9
-9 x 1
-3 x 3

And when you add them together you get:
-1 + 9 = 8
-9 + 1 = -8
-3 + 3 = 0

Sorry but there is not an answer. :(

At a grocery​ store, you want to buy 3 3/5 lb of . What decimal should the digital scale​ show?
nasty-shy [4]

Answer:

3.6 lb

Step-by-step explanation:

to find the decimal of a fraction, you simply divide the numerator by the denominator. 3 divided by 5 equals 0.6, which is added to the end of your whole number.
