Answer:
18%
Step-by-step explanation:
0.12 is 12 percent.
We also have the 0.06 percent which would just be 6 percent
We need to add up those percentages to get 18 percent, for the people surveyed that cannot swim would be 18 percent.
Our final answer is D.
Answer:
The measure of angle 2 is 52°.
Step-by-step explanation:
Consider the below figure attached with this question.
It is given that

and x=6.
From the below figure it is clear that Lines 1,2 and 3 intersect each other at a point and form 6 angles.
It is clear that angle 2 and angle 5 are vertical opposite angles because these angles created by intersection of line 2 and line 3.
If two lines intersect each other then vertical opposite angles are congruent.
(vertical opposite angles)

Substitute x=6.



Therefore, the measure of angle 2 is 52°.
To find the intersection points, you take x^2 - 4x + 9 = -2x + 17
This gives x^2 - 2x - 8 = 0,
which factorises to (x - 4)(x + 2) = 0, giving the solutions x = 4 or x = -2
From the graph, we can see that x is positive, meaning x = 4, so a = 4.
Substituting x = 4 into y = -2x + 17, we get y = -2(4) + 17 = 9, so b = 9.
a + b = 4 + 9 = 13. The answer is B.
