If one doctor warns 3 out of 10 people who are not vaccinated will suffer from flu like symptoms then, that means 30% of the people who are not vaccinated will suffer from flu symptoms. So in a study of 1 million unvaccinated inhabitants we would take 30% of 1 million which is 300,000. If 12,000 unvaccinated people suffer from the flu that means the amount of people who were unvaccinated and also do not experience the flu like symptoms would be I believe 70% of 12,000 which is 8400

Answer:

1-for the first part of this its truly simple...

basically the doctor warns that 3 out of 10 people will suffer from the flu(unvaccinated) which in percentage form equates to 33.3%...therefore in city full of (unvaccinted) people only 333000 people will get infected with the flu

2-in this case its simple...In this particular question the 12,000 people refers to the 3 people out of 10 who were not vaccinated and contracted the flu...now if in this case once again in a city of 1000000 people if 12,000 is infected the rest is obviously not vaccinated therefore it will be 1,000,000-12000=988000 people who did not suffer from the flu

just remember this answer may not ne right...I do not wish to take responsibility if this answer is wrong...this question may also be typed wrong...but anywho's

it's my pleasure to assist

Two column proof:

gulaghasi [49]

Answer:

Given : BRDG is a kite that is inscribed in a circle,

With BR = RD and BG = DG

To prove : RG is a diameter

Proof:

Since, RG is the major diagonal of the kite BRDG,

By the property of kite,

∠ RBG = ∠ RDG

Also, BRDG is a cyclic quadrilateral,

Therefore, By the property of cyclic quadrilateral,

∠ RBG + ∠ RDG = 180°

⇒ ∠ RBG + ∠ RBG = 180°

⇒ 2∠ RBG = 180°

⇒ ∠ RBG = 90°

⇒ ∠ RDG = 90°

Since, Angle subtended by a diameter or semicircle on any point of circle is right angle.

⇒ RG is the diameter of the circle.

Hence, proved.

2. Given a quadrilateral with vertices (−1, 3), (1, 5), (5, 1), and (3,−1):

zlopas [31]

<h2>Explanation:</h2>

In every rectangle, the two diagonals have the same length. If a quadrilateral's diagonals have the same length, that doesn't mean it has to be a rectangle, but if a parallelogram's diagonals have the same length, then it's definitely a rectangle.

So first of all, let's prove this is a parallelogram. The basic definition of a parallelogram is that it is a quadrilateral where both pairs of opposite sides are parallel.

So let's name the vertices as:

$A(-1,3) \\ \\ B(1,5) \\ \\ C(5,1) \\ \\ D(3,-1)$

First pair of opposite sides:

<u>Slope:</u>

$\text{For AB}: \\ \\ m=\frac{5-3}{1-(-1)}=1 \\ \\ \\ \text{For CD}: \\ \\ m=\frac{1-(-1)}{5-3}=1 \\ \\ \\ \text{So AB and CD are parallel}$

Second pair of opposite sides:

<u>Slope:</u>

$\text{For BC}: \\ \\ m=\frac{1-5}{5-1}=-1 \\ \\ \\ \text{For AD}: \\ \\ m=\frac{-1-3}{3-(-1)}=-1 \\ \\ \\ \text{So BC and AD are parallel}$

So in fact this is a parallelogram. The other thing we need to prove is that the diagonals measure the same. Using distance formula:

$d=\sqrt{(y_{2}-y_{1})^2+(x_{2}-x_{1})^2} \\ \\ \\ Diagonal \ BD: \\ \\ d=\sqrt{(5-(-1))^2+(1-3)^2}=2\sqrt{10} \\ \\ \\ Diagonal \ AC: \\ \\ d=\sqrt{(3-1)^2+(-5-1)^2}=2\sqrt{10} \\ \\ \\$

So the diagonals measure the same, therefore this is a rectangle.
