Answer:
36
Step-by-step explanation:
The answer would be 36 :)
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= 
Step-by-step explanation:
−(7−2x)+7=−7
To find the opposite of 7−2x, find the opposite of each term.
−7−(−2x)+7=−7
The opposite of −2x is 2x.
−7+2x+7=−7
Add −7 and 7 to get 0.
2x=−7
Divide both sides by 2.
Fraction −7/2 can be rewritten as −2/7 by extracting the negative sign.
Answer:
21cm
Step-by-step explanation:
<em>Solution,</em>
<em>Length of fish=40mm=40/10=4cm</em>
<em>Length of pig=25cm</em>
<em>Now, </em>
<em>Difference of their length=25cm-4cm=21cm</em>
<em />
<em>Hence,the pig is 21cm long than the fish</em>
