Answer:

Step-by-step explanation:

Because the lines are intersecting they are equal to 180. Therefore...

(x+23) + (2x+4) = 180

3x + 27 = 180

3x = 153

x = 51

Solutions 

1) <span>Add the whole numbers first ( 7 and 2 )

</span><span>9+<span>7/8</span>+<span>11/12

2) </span></span>Find the Least Common Denominator (LCD) of 

<span><span>7 / 8</span>,<span>11 / 12
</span></span>
Start by Listing Multiples

List out all multiples of each denominator, and find the first common one.

8 : <span><span>8,16,24</span>
</span>
12 : <span>12,24
</span>
Therefore, the LCD is <span>24 

</span>Method 2: By Prime Factors

List all prime factors of each denominator, and find the union of these primes.

8 : <span>2,2,2
</span>
12 : <span>2,2,3
</span>
Therefore, the LCD is <span>2×2×2×3=24

3) </span>Make the denominators the same as the LCD

<span>9+<span><span>7×3 / </span><span>8×3</span></span>+<span><span>11×2 / </span><span>12×2

</span></span></span>4) Simplify. Denominators are now the same

<span>9+<span>21 / 24</span>+<span>22 / 24

5) J</span></span>oin the denominators

<span>9+<span><span>21+22 / </span>24</span></span>
6) Simplify

<span>9+<span>43 / 24

7) </span></span>Convert 43 / 24 <span>to mixed fraction

</span><span>9+1 <span>19 / 24

8) </span></span>Simplify

<span><span>10 <span>19 / 24</span></span></span>

On average 20% of the calculators produced in a factory are faulty. Samples of 10 calculators are to be selected at a random eac
enyata [817]

The probability that in any one sample, two calculators or less will be faulty is; 100%

<h3>Probability and Random sampling</h3>

According to the task content;

  • A statement of fact indicates that; 20% of the calculators produced in a factory are faulty.

Hence, it follows that, when a sample of 10 calculators is selected randomly each day, 2 of the calculators are faulty by proportion.

Ultimately, the probability that in any one sample, two calculators or less will be faulty is; 100%.
