if y=2x then the y for -1 would be -2

so your first coordinates are )-1, -2) and so on so forth

second coordinates are (0,0) third are (1,2) fourth are (3,6) fifth are (4,8)

not sure if that's what you had or not but that should be about right.

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 greatest number of right angles a hexagon can have?

finlep [7]

So hexagon is 6 sides and 6 angles
it can have a max of 2 right angles
if you make an irregular hexagon with one of the lines going into the figure then the answer is 4

if you have all the lines outside of the hexagon then the max is 2

There are five boys to every nine girls in an introductory engineering course .if there are 364 students enrolled in the course

Nadusha1986 [10]

Answer:

234

Step-by-step explanation:

So what we know is that

5x+9x= students

This equation is saying that for every 5 boys there are 9 girls

we can then plug in 364 for the number of students and add like terms

This means that 14x=364

this means that x=26

This means that there are 26 sets of 5 boys and 9 girls

this means that there are

130 boys

234 girls
