You didn't include the options, but one and only one line passes through two poins.

You can find the equation of the line that passes through two known points in this way:

[Y -Y1] / [X -X1] = [Y2 - Y1] / [X2 -X1]

in this case (X1,Y1) = (-2,2) and (X2,Y2) = (2,4)

=> [Y - (2) ] / [X - (-2) ] = [4 - 2] / [2 - (-2) ]

=> [Y -2] / [X + 2] = 2/4 = 1/2

=> 2 * (Y - 2)  = X + 2

=> 2Y - 4 = X + 2

=> 2Y = X + 2 + 4

=> 2y = x + 6

=> y = x/2 + 3

So you must look the graph of that equation.

Some of the points of that graph are:

x         y

-6       -6/2 + 3 = 0

-4        -4/2 + 3 = 1

-2         -2/2 + 3 = 2

0           0 + 3 = 3

2           2/2 + 3 = 4

4           4/2 + 3 = 5

So, you should find the correspondant graph easily.

Answer:

Attachment for graph.

Step-by-step explanation:

Given: (-2,2) and (2,4)

Two points are given and to find the equation of line passing through the points.

First we find the slope of the line.

\text{Slope }=\dfrac{4-2}{2+2}

              =\dfrac{1}{2}

Point: (2,4)

using point slope form:

y-y_1=m(x-x_1)

y-4=\dfrac{1}{2}(x-2)

y=\dfrac{1}{2}x+3

Now, we draw the graph using two given points. Plot the points on graph and join them.

Yahoo creates a test to classify emails as spam or not spam based on the contained words. This test accurately identifies spam (
Amiraneli [1.4K]

Answer and Step-by-step explanation:

The computation is shown below:

Let us assume that

Spam Email be S

And, test spam positive be T

Given that

P(S) = 0.3

P(\frac{T}{S}) = 0.95

P(\frac{T}{S^c}) = 0.05

Now based on the above information, the probabilities are as follows

i. P(Spam Email) is

= P(S)

= 0.3

P(S^c) =  1 - P(S)

= 1 - 0.3

= 0.7

ii. P(\frac{S}{T}) = \frac{P(S\cap\ T}{P(T)}

= \frac{P(\frac{T}{S}) . P(S) }{P(\frac{T}{S}) . P(S) + P(\frac{T}{S^c}) . P(S^c) }

= \frac{0.95 \times 0.3}{0.95 \times 0.3 + 0.05 \times 0.7}

= 0.8906

iii. P(\frac{S}{T^c}) = \frac{P(S\cap\ T^c}{P(T^c)}

= \frac{P(\frac{T^c}{S}) . P(S) }{P(\frac{T^c}{S}) . P(S) + P(\frac{T^c}{S^c}) . P(S^c) }

= \frac{(1 - 0.95)\times 0.3}{ (1 -0.95)0.95 \times 0.3 + (1 - 0.05) \times 0.7}

= 0.0221

We simply applied the above formulas so that the each part could come

What is the other square root of 119 + 120i?
MakcuM [25]

Answer:

\sqrt{119+120 i}=\pm (12.24+i 4.90)

Step-by-step explanation:

Given

z = 119 + 120 i

Let \sqrt{119+120 i}=p+iq

Squaring both sides

119+120 i=p^2-q^2+2ipq

Comparing real and imaginary part

Re(LHS)=Re(RHS)

119=p^2-q^2...........................(1)

comparing Im(LHS)=Im(RHS)

120=2pq

q=\frac{60}{p}

Substitute q in 1

119=p^2-(\frac{60}{p})^2

p^4-119p^2-(68)^2=0

Let x=p^2

x^2-119x-4624=0

x=\dfrac{119\pm \sqrt{119^2+4\times 4624}}{2}

x=\frac{119\pm 180.71}{2}

we take only Positive value because p^2=x

x=149.85  

p^2=149.85

thus p=\pm 12.24

q=\pm 4.90

thus,

\sqrt{119+120 i}=\pm (12.24+i 4.90)
