Three students are trying to find the diameter of circle C. Gregory believes the diameter is equal to the length of chord XY. Ma

ria believes chord WY can be added to create the right triangle WZY. She also thinks the hypotenuse of ΔWZY has a length equal to the radius of the circle.
Jordan believes segment WZ lies on the diameter of the circle, and that if the diameter is drawn, he can make an equation relating the pieces of that diameter of the circle to the pieces of .

The student with the correct approach to finding the diameter is . The diameter of the circle is units.

Graph the line whose y-intercept is - 9 and whose x-intercept is 5.
Nostrana [21]

Answer:

y=1.8x-9

Step-by-step explanation:

if they are intercepts so the x/y will be zero, so in y intetceot the x is zero, and in the x itercept the y is zero.

0,-9

5,0

we calculate the slooe / rise

-9-0/0-5 = 1.8

we then use this formula

y-y1=rise(x-x1)

y-0=1.8(x-5)

y=1.8x-9

Software to detect fraud in consumer phone cards tracks the number of metropolitan areas where calls originate each day. It is f
pashok25 [27]

Answer:

0.999987

Step-by-step explanation:

Given that

The user is a legitimate one = E₁

The user is a fraudulent one = E₂

The same user originates calls from two metropolitan areas  = A

Use Bay's Theorem to solve the problem

P(E₁) = 0.0131% = 0.000131

P(E₂) = 1 - P(E₁)  = 0.999869

P(A/E₁) = 3%  = 0.03

P(A/E₂) = 30% = 0.3

Given a randomly chosen user originates calls from two or more metropolitan, The probability that the user is fraudulent user is :

P(E_2/A)=\frac{P(E_2)\times P(A/E_2)}{P(E_1)\times P(A/E_1)+P(E_2)\times P(A/E_2)}

=\frac{(0.999869)(0.3)}{(0.000131)(0.03)+(0.999869)(0.3)}

\frac{0.2999607}{0.00000393+0.2999607}

\frac{0.2999607}{0.29996463}

= 0.999986898 ≈ 0.999987

sesenic [268]

9514 1404 393

Answer:

  x = 12

Step-by-step explanation:

The square of the length of the tangent segment is equal to the product of lengths from the external common point to the two circle intersections of the secant.

  x^2 = (2)(70+2)

  x^2 = 144

  x = √144

  x = 12

Which parabola has the graph shown?<br><br> I think the answer is C. however, I'm not 100% sure.
NemiM [27]

x=m(y-k)^2+h\\\\(h,\ k)-the\ vertex

We have the vertex (-4, -1), therefore we have:

x=(y-(-1))^2-4\ \ \ |+4\\\\(x+4)=(y+1)^2
