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

find the point on the terminal side of θ = negative three pi divided by four that has an x coordinate of negative 1
Mila [183]
Check the picture below, is a negative angle, thus, is going "clockwise"

\bf tan(\theta)=\cfrac{opposite}{adjacent}\qquad tan\left( -\frac{3\pi }{4} \right)=\cfrac{y}{x}\implies  tan\left( -\frac{3\pi }{4} \right)=\cfrac{y}{-1}&#10;\\\\\\&#10;-1\cdot  tan\left( -\frac{3\pi }{4} \right)=y\implies -1\cdot \cfrac{sin\left( -\frac{3\pi }{4} \right)}{cos\left( -\frac{3\pi }{4} \right)}=y&#10;\\\\\\&#10;-1\cdot \cfrac{-1}{-1}=y\implies -1

The equation of a parabola is given.
BlackZzzverrR [31]

Answer:

Directrix equation:  y = 11/2

y = k - c = 6 - 1/2 = 11/2

Step-by-step explanation:

y=(1/2) x^2+6x+24

factor this

y =  (1/2)* [  x^2  + 12x  ]  +  24

y =  (1/2)* [  x^2  + 12x  + 36  -  36]  +  24

y =  (1/2)* [  (x + 6)^2  -  36]  +  24

y =  (1/2)*   (x + 6)^2  - 18 +  24

y =  (1/2)*   (x + 6)^2  + 6

y - 6 =  (1/2)*   (x + 6)^2

2*(y - 6)  =   (x + 6)^2

4c = 2,   (h, k) = (-6, 6)

c = 1/2

Directrix equation:  y = k - c = 6 - 1/2 = 11/2
