Answer:

1/12

Step-by-step explanation:

Total sub consumed = ¼ + ⅔

= [3(1) + 4(2)]/12 (LCM is 12)

= 11/12

Left = 1 - 11/12 = 1/12

The strata are formed on the basis of the characteristics shared by members .
After the formation of strata, researcher randomly selects participants from each strata to ensure that that the participant of every group must involve in the sample to represent each character.

Solving systems of equations using substitution/elimination

Step-by-step explanation:

Step 1: Define Systems

-5x + 6y = 55

4x + 3y = 34

Step 2: Rewrite Systems

4x + 3y = 34

Multiply everything by -2: -8x - 6y = -68

Step 3: Redefine Systems

-5x + 6y = 55

-8x - 6y = -68

Step 4: Solve for x

Elimination

Combine equations: -13x = -13
Divide -13 on both sides: x = 1

Step 5: Solve for y

Define equation: 4x + 3y = 34
Substitute in x: 4(1) + 3y = 34
Multiply: 4 + 3y = 34
Isolate y term: 3y = 30
Isolate y: y = 10

The game of Scrabble has 100 tiles. The diagram shows the number of tiles for each letter and the letter's point value. One til

egoroff_w [7]

Answer:

10%

Step-by-step explanation:

In the image attached below, we can see that there are

8 tiles of letter O

2 tiles of letter V

This means that there are 10 total tiles of the letters that you want to get (O and V). Since there are a total of 100 tiles we need to divide this value by 100 to get the probability of getting one of these tiles.

10 / 100 = 0.10 or 10%

Finally, we can see that the probability of selecting a O or a V is 10%
