Problem 7
Time is always an independent variable because time marches on doing its own thing without depending on external forces, or other people/things. Instead, other variables depend on time. In this case, the distance d depends on the independent variable t for time.
If the time goes up by 1 hour, then the distance variable goes up by 3 miles. In short, that tells us his speed is 3 mph.
Answer: Choice A) independent = time; dependent = distance

Problem 8
Everywhere you see an x, replace it with 9. Then use PEMDAS to simplify
f(x) = 5x - 9
f(9) = 5(9) - 9 ... x replaced with 9
f(9) = 45 - 9
f(9) = 36
Answer: 36
X is between 80 and 90, if the square root of a number (x) is 9, you would do 9x9 to solve for x, x=81
The probability of 3 failures or less is about 0.83886, so that is the probability the machine will be working.
Answer:
<h3><em>
315 red flowers</em></h3><h3><em>
420 white flowers</em></h3><h3><em>
315 yellow flowers</em></h3>
Step-by-step explanation:
1050 flowers
3/10 of them are red=> 3/10 *1050=3*105=315 red flowers
2/5, (or 4/10), are white =>4/10 * 1050=4*105=420 white flowers
=> 1050-(315+420)=1050-735=315 yellow flowers
