Kisachek [45]

Complelment adds to 90

let's say the complement is B

A+B=90
4x+2+B=90
minus (4x+2) from both sides
B=88-4x

\250 doctors from three countries in Europe meeting in a conference to decide whether to approve a new vaccine for the flu. Amon

Bezzdna [24]

Answer:

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

Step-by-step explanation:

(a) What is the probability that a randomly chosen doctor is in favor of the vaccine

75% of 115/250 = 0.46(German).

60% of 65/250 = 0.26(French).

65% of 70/250 = 0.28(Englishmen). So

$p = 0.75*0.46 + 0.6*0.26 + 0.65*0.28 = 0.683$

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine

How would I translate this algebraic expression?

FromTheMoon [43]

Answer: $\frac{5}{7} (2+\frac{6}{r} )$

Step-by-step explanation:

Since, the quotient of 6 and r = $\frac{6}{r}$

The sum of two and the quotient of 6 and r

= $(2+\frac{6}{r} )$

And, Five-sevenths of the sum of two and the quotient of 6 and r

= $\frac{5}{7} (2+\frac{6}{r} )$

Thus, the required expression is, $\frac{5}{7} (2+\frac{6}{r} )$
