Consider an experiment where we ask what type of car – either domestic (e.g., Chevrolet, Ford, Chrysler, etc.), foreign built ab
Nostrana [21]

Answer:

12^{20} outcomes for this sample space (under some considerations)

Step-by-step explanation:

Let's define the multiplication principle.

If a first part of an experiment can happen in n1 ways, a second part of an experiment can happen in n2 ways , . . . , a i - part of an experiment can happen in ni ways, then the total outcomes for the all the experiment are

(n1) x (n2) x ... x (ni)

In this exercise n1 = domestic

n1 is the total classes for domestic category

(Let's suppose n1 = 3 because of Chevrolet, Ford and Chrysler)

n2 = 1 (Also supposing we only have ''a Toyota built in Japan'' category for n2)

n3 = 1 (Also supposing we only have ''A Toyota built in Kentucky'' category for n3)

n4 = 4 (Also supposing we only have ''sedan,hatchback, truck or SUV'' category for n4

The possible outcomes for one person in the experiment are

(Domestic).(ForeignBuiltAbrod).(ForeignBuiltInTheU.S).(Style)

Where what it is brackets are the possible categories for that classification.

n1.n2.n3.n4=3.1.1.4=12

We have 20 different people then 12^{20} are the possible outcomes sample space

In the sample space there are 12^{20} outcomes if we consider that we have 3 types of domestic car, 1 type of foreign car built abroad,1 type of foreign car built in the U.S and 4 differents styles for this 20 different people.

Solve the system by substitution. Check your solution.
postnew [5]

Answer:

(9,126)

Step-by-step explanation:

Make sure x and y are on the same side

0.5x+0.25y=36\\16x-1y=18

Eliminate y by multiplying the first equation by 4 then adding both equations together

2x+1y=144\\16x-1y=18\\18x=162\\x=9

Plug the x value (9) into one of the equations

16(9)-1y=18

Solve

16(9)-1y=18\\144-1y=18\\144=18+1y\\126=y

x=9, y=126

MARKING BRAINLIEST!!!<br><br> PLZ answer BOTH questions!!
Alexxx [7]

Answer:

The answer to your question is:

12) C

13) AT = 29

Step-by-step explanation:

12)

Data

A (6, -3)

B (-6, 19)

midx = (x1 + x2) / 2                            midy = (y1 ´y2) / 2

midx = ( 6 - 6) / 2                               midy = (-3 + 19) / 2

midx = 0 / 2                                      midy = 16 / 2

midx = 0                                            midy = 8

               mid point = (0, 8)

13)

As A is the midpoint of CT then CA = AT

                                  2x - 19 = x + 5

                                  2x - x = 19 + 5

                                  x = 24

                AT = 24 + 5

                AT = 29
