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

0.683 = 68.3% probability that a randomly chosen doctor is in favor of the vaccine
<u>Answer:</u>
The money will gavin have after 5 years is 1616.59$
<u>Explanation:</u>
We know that compound interest is given by

Where A = final amount
P = Principal amount = $1500 (given)
r = interest rate = 1.5% = 0.015
n = no. of times interest applied per time period = given quarterly = 4
t = time period = 5 years
So,


= 1616.59$ which is the money will gavin have after 5 years
Still no question and you didn't even finish the statement but if you post the rest maybe I could help
x = 56°
Solution:
Part A:
Given data:
2x and 68° are adjacent angles in a straight line and their measures have sum of 180°.
Part B:
<em>Sum of the adjacent angles in the straight line is 180°.</em>
2x + 68° = 180°
Subtract 68° from 180°, we get
⇒ 2x = 112°
Divide by 2 on both sides, we get
⇒ x = 56°
The value of x is 56°.
Part C:
By part A and part B,
2x° + 68° = 2(56°) + 68°
= 112° + 68°
= 180°
2x° + 68° = 180°
Hence proved.
