By knowing the <em>blood</em> pressure and applying the <em>quadratic</em> formula, the age of a man whose normal <em>blood</em> pressure is 129 mm Hg is 40 years old.
<h3>How to use quadratic equations to determine the age of a man in terms of blood pressure</h3>
In this problem we have a <em>quadratic</em> function that models the <em>blood</em> pressure as a function of age. As the latter is known, we must use the quadratic formula to determine the former:
129 = 0.006 · A² - 0.02 ·A + 120
0.006 · A² - 0.02 · A - 9 = 0

A = 1.667 + 38.733
A = 40
By knowing the <em>blood</em> pressure and applying the <em>quadratic</em> formula, the age of a man whose normal <em>blood</em> pressure is 129 mm Hg is 40 years old.

Answer: F. The Theoretical Probability is Greater than the Experimental Probability.
Step-by-step explanation: Theoretical probability gives you the odds of every outcome. With flipping a coin, the outcome odds of tails would always be 1/2. Experimental probability is the actual outcome that results from trials. During trials, tails was flipped 8 times. We can simplify 8/20 flips to find that tails was flipped 2/5 flips. In decimal form, 1/2 simbolizes .5 or 50%. 2/5 simbolizes .4 or 40%. The theoretical probability is greater than the experimental probability.
Answer:
449,100 pounds
Step-by-step explanation:
0.2% in decimal form is 0.002
0.002 (percent lost) * 450,000 (weight) = 900 (pounds lost)
450,000 - 900 = 449,100 pounds
Answer:
8.65%
Step-by-step explanation:
We have been given that Debra earns $4740 per month. Every month she saves $410. Additionally, she has $2520 in outstanding credit cards and makes a $210 monthly payment of these cards.

Upon substituting our given values in above formula, we will get:




Therefore, Debra's approximate savings ratio is 8.65%.
Answer:
Step-by-step explanation:
- 4*3=12
- 12-1=11
- so 4*3 remander 1= 11r
