Answer: 1/8

Step-by-step explanation: The sample space are all of the different outcomes an event can lead to. The H and T combinations at the bottom are all of the different outcomes. I think the probability of getting 3 tails for the coins (or TTT) is 1/8. This is because there are 24 total outcomes (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT). There is 3/24 TTTs (also, 1/8 if you count the groups/simplify). Therefore, it is 1/8. Hope this helps!

Answer:

<h2><em><u>3</u></em></h2>

Step-by-step explanation:

<h3><u>Given</u><u> </u><u>question</u><u>:</u></h3>

<em>To</em><em> </em><em>simplify</em><em> </em><em>-</em><em> </em>

$14 + 16 \div {2}^{3} - (12 + {3}^{2} ) \div 7 + 2 \times ( - 5)$

<h3><u>Solution</u><u>:</u></h3>

<em>According</em><em> </em><em>to</em><em> </em><em>PEMDAS</em><em> </em><em>rule</em><em>,</em>

<em>[</em><em>First</em><em> </em><em>parenthesis</em><em>]</em>

$= 14 + 16 \div {2}^{3} - (12 + 9 ) \div 7 + 2 \times ( - 5)$

$= 14 + 16 \div {2}^{3} - 21 \div 7 + 2 \times ( - 5)$

<em>[</em><em>Then</em><em> </em><em>exponents</em><em>]</em>

$= 14 + 16 \div 8 - 21 \div 7 + 2 \times ( - 5)$

<em>[</em><em>Then</em><em> </em><em>multiplication</em><em>]</em>

= 14 + 16 ÷ 8 - 21 ÷ 7 - 10

<em>[</em><em>Then</em><em> </em><em>division</em><em>]</em>

= 14 + 2 - 3 - 10

<em>[</em><em>Then</em><em> </em><em>addition</em><em>]</em>

= 16 - 13

<em>[</em><em>Then</em><em> </em><em>subtraction</em><em>]</em>

= <em><u>3</u></em><em><u> </u></em><em><u>(</u></em><em><u>Ans</u></em><em><u>)</u></em>

Find the midpoint of the line segment with the given endpoints: (-1, -6) and (-6, 5).

Vikentia [17]

Answer:

Step-by-step explanation:

First, we will find the midpoint for the x - coordinate first.

Midpoint (x) = $\frac{-1+(-6)}{2} \\=\frac{-1-6}{2} \\=\frac{-7}{2} \\=-3.5$

Now we will find the midpoint for the y - coordinate.

Midpoint (y) = $\frac{-6+5}{2} \\=\frac{-1}{2} \\=-0.5$

Therefore from these 2 values we know that the midpoint of this 2 points is (-3.5,-0.5)

Solve the inequality 4(n-3)- 6 > 18

Sonbull [250]

Answer:

n>9

Step-by-step explanation:

4(n-3)- 6 > 18

To solve this inequality we need to remove the parenthesis

distribute 4 inside the parenthesis

4n -12 - 6 > 18

Now combine like terms

4n - 18 > 18

We need to isolate 'n', so we add 18 on both sides

4n > 36

Now divide both sides by 4

n > 9

So the value of n is greater than 9
