From birth to 5yo = 91,200
from 5 to 18yo = 167,000
therefore from birth to 18yo will cost 91,200 + 167,000 which is 258,200
Since the question says per year and thats the total cost of 18 years ( from 0 years to 18), we divide it by 18.
258,200 ÷ 18 = 14,344
Answer a: 14,344
Compare the slopes of each line<span>. Remember, when two </span>lines are parallel<span> to each other, they will have the exact same slope. Using the equation y = mx + b where m is the slope of the </span>line<span>, you can </span>identify<span> and compare the slopes of two </span>lines<span>.</span>

Step-by-step explanation:
Answer:
the probability is 2/9
Step-by-step explanation:
Assuming the coins are randomly selected, the probability of pulling a dime first is the number of dimes (4) divided by the total number of coins (10).
p(dime first) = 4/10 = 2/5
Then, having drawn a dime, there are 9 coins left, of which 5 are nickels. The probability of randomly choosing a nickel is 5/9.
The joint probability of these two events occurring sequentially is the product of their probabilities:
p(dime then nickel) = (2/5)×(5/9) = 2/9
_____
<em>Alternate solution</em>
You can go at this another way. You can list all the pairs of coins that can be drawn. There are 90 of them: 10 first coins and, for each of those, 9 coins that can be chosen second. Of these 90 possibilities, there are 4 dimes that can be chosen first, and 5 nickels that can be chosen second, for a total of 20 possible dime-nickel choices out of the 90 total possible outcomes.
p(dime/nickel) = 20/90 = 2/9
