Answer:
2 out of 6
Step-by-step explanation:
P( blue marble) = number of blue marbles / total marbles
= 2 /6
As we can see from the question, the pattern that emerges is that each year since the end of the second year, Alvin's account is being reduced by $3,000.
So, at the end of the third year his account is $19000-$3000=$16000
Likewise, at the end of the fourth year his account will have $16000-$3000=$13000
Thus at the end of the fifth year his account will have $13000-$3000=$10000
Therefore, from the given options, $10000 is the correct answer.
Answer:
2400 miles
Step-by-step explanation:
So the first equation is pretty straight forwards, it's in the slope-intercept form y=mx+b where m is the slope, and b is y-intercept, since as x increases by 1, the value y increases by m, which by definition is what the slope is, so m is the slope. In this context the slope is how many miles in x hours. So Space Explorer B flies 400 miles per hour. The amount of miles that Space Explorer A flies per mile can be calculated by dividing the 36400 by the 13 hours it had to travel. This gives you 2800 miles. So to find how many fewer miles Space Explorer B travels than Space Explorer A you subtract the 2 slopes. 2800 - 400 = 2400. So Space Explorer B travels 2400 fewer miles than Space Explorer A
