Answer:

<em>The sum of 4 consecutive odd number is 80</em>

<em>Let X be the first of these numbers</em>

<em>Then the next odd number is X+2</em>

<em>The third is X+4The fourth is X+6</em>

<em>All of these add up to 80</em>

<em>(X) + (X+2) + (X+4) + (X+6) = 80</em>

<em>Using the commutative and associative laws, let's transform this equation into</em>

<em>(X + X + X + X) + (2 + 4 + 6) = 804X + 12 = 80</em>

<em>Subtract 12 from both sides of the equation gives4X = 68</em>

<em>Divide both sides by 4 gives</em>

<em>X = 17</em>

<em>Going back to the original question:What are the 4 consecutive odd numbers: 17, 19, 21, 23Checking our answer:17 + 19 + 21 + 23 = 80 Correct!</em>

What is the chance of drawing a yellow ball then a red ball from a bag containing 3 yellow balls and 7 red balls?
Ainat [17]
Talking as if the balls do not get put back into the bag, the first probability is 3/10 for yellow. For red it will be 7/9 because there is one less ball (yellow) in the bag.

solong [7]

The percent increase in population is: 87%

Further explanation:

The percent change is given by:

Percent\ increase=\frac{Increase}{Original\ number}*100

Population before 10 years = 25800 people

Population after 10 years= 48200 people

Increase=48200-25800=22400\ people

Putting the values in the formula:

Percent\ Increase=\frac{22400}{25800}*100\\=0.8682*100\\=86.82\%\\Rounding\ off\ to\ nearest\ percent\\87\%

The percent increase in population is: 87%
