The required probability that a patient had surgery and experienced a major improvement 31% and that a patient received nonsurgical treatment 14.5%.
<h3>What is probability?</h3>
Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Number of patients who got surgery = 398,
63% of percent said they had a major improvement in their condition,
= 0.63 * 398 ≈ 250
29% among those who received nonsurgical treatment,
= 0.29 * (803 - 398)
= 0.29 * 405
≈ 117
Now,
The probability that a patient had surgery and experienced a major improvement in his or her condition.
= 250 / 803
= 31%
The probability that a patient received nonsurgical treatment and experienced an improvement in his or her condition.
= 117 / 803
= 14.5%
Thus, the required probability is 31% and 14.5%.

Answer: x=-1, y=7. 1st eqaution=-1+7=6, 2nd eqaution=7+-3=4
Leftover fraction is 1 - (1/3 + 1/4 + 1/6) = 1 - 3/4 = 1/4 Answer
B. First pizza:- 1 - 1/3 = 2/3 had been eaten.
Second pizza:- 1 - 1/4 = 3/4 was eaten.
Third pizza:- 1 - 1/6 = 5/6 was eaten.
C.
Total amount of pizza eaten = 3 - 3/4 = 9/4 = 2 1/4
Amount eaten per person = 9/4 / 6 = 3/8 of a pizza
Answer:
B
Step-by-step explanation:
Use the formula for radius and circle circumference.

Since we know the diameter, if we divide that by 2, we can get the radius.

Now we can plug that value into the circumference formula to get the circumference.

*Since we're rounding to the nearest inch.
