Answer:

Radius matches with option F.

Arc matches with option D.

Chord matches with option C.

Secant matches with option E

Tangent matches with option A

Circumference matches option B

Step-by-step explanation:

Given the diagram in which chord is given, arc is given and secant is given.

we have to match the terms with their characteristics.

Radius is a segment between the centre of a circle and a point on the circle where the distance is same from each point of circumference to center.

Radius matches with option F.

Arc is the portion of the circle between points B and C is darkened represented in figure 2.

Arc matches with option D.

Chord of a circle is a line segment connecting points B and C which are on the circle shown in circle 1.

Chord matches with option C.

Secant is a line segment connecting points B and C which are on the circle shown in circle 3.

Secant matches with option E

Tangent that is a line intersects a circle in exactly one point.

Tangent matches with option A

Circumference is the distance around a circle.

Circumference matches with option B

Answer:

jyyj

Step-by-step explanation:

From the figure,

Radius matches with (F) that is a segment between the centre of a circle and a point on the circle.

Arc matches with (D) that is Circle A and the portion of the circle between points B and C is darkened.

Chord matches with (C) Circle A and a line segment connecting points B and C which are on the circle.

Secant matches with (E) that is Circle A and a line segment connecting points B and C which are on the circle.

Tangent matches with (A) that is a line intersects a circle in exactly one point.

Circumference matches (B) that is the distance around a circle.

Answer:

45.8

Step-by-step explanation:

We need to find the surface area for this entire figure!

We can see that this is a pyramid here - we must find the area of the 3 triangles and the base triangle at the bottom.

The 3 triangles building up the pyramid are all equal to each other.

To find the area of a triangle, use $Area = base*height/2$

$Area=3(\frac{5*7}{3} )+(\frac{5*4.3}{2})\\Area=35+10.75=45.75$

Round to the nearest tenth: 45.75 -> 45.8

On any given day, the probability that a large local river is polluted by carbon tetrachloride is 0.12. Each day, a test is cond

babymother [125]

Answer:

a) 0.2416

b) 0.4172

c) 0.0253

Step-by-step explanation:

Since the result of the test should be independent of the time , then the that the test number of times that test proves correct is independent of the days the river is correct .

denoting event a A=the test proves correct and B=the river is polluted

a) the test indicates pollution when

- the river is polluted and the test is correct

- the river is not polluted and the test fails

then

P(test indicates pollution)= P(A)*P(B)+ (1-P(A))*(1-P(B)) = 0.12*0.84+0.88*0.16 = 0.2416

b) according to Bayes

P(A∩B)= P(A/B)*P(B) → P(A/B)=P(A∩B)/P(B)

then

P(pollution exists/test indicates pollution)=P(A∩B)/P(B) = 0.84*0.12 / 0.2416 = 0.4172

c) since

P(test indicates no pollution)= P(A)*(1-P(B))+ (1-P(A))*P(B) = 0.84*0.88+ 0.16*0.12 = 0.7584

the rate of false positives is

P(river is polluted/test indicates no pollution) = 0.12*0.16 / 0.7584 = 0.0253
