What I'd the equation of a line that passes through points (-2,6) and (4,-3)?

Blababa [14]

slope = (y2-y1)/(x2-x1)

m = (-3-6)/(4--2)

= -9/6

=-3/2

y -y1 = m(x-x1)

y-6 =-3/2 (x--2)

y-6 =-3/2 (x+2)

y-6 =-3/2 x -3

add 6

y = -3/2 x +3

A college sends a survey to members of the class of 2012. Of the 1254 people who graduated that year, 672 are women, of whom 124

Svetllana [295]

Answer:

a) $P(F) = \frac{672}{1254}=\frac{112}{209}=0.536$

b) $P(M) = \frac{582}{1254}= \frac{97}{209}=0.464$

c) $P(A') = 1-P(A) = 1- \frac{124}{672}= \frac{137}{168}=0.815$

Step-by-step explanation:

For this case we have a total of 1254 people. 672 are women and 582 are female.

We know that 124 women wnat on to graduate school.

And 198 male want on to graduate school

We can define the following events:

F = The alumnus selected is female

M= The alumnus selected is male

A= Female and attend graduate school

And we can find the probabilities required using the empirical definition of probability like this:

Part a

$P(F) = \frac{672}{1254}=\frac{112}{209}=0.536$

Part b

$P(M) = \frac{582}{1254}= \frac{97}{209}=0.464$

Part c

For this case we find the probability for the event A: The student selected is female and did attend graduate school

$P(A) =\frac{124}{672}=\frac{31}{168}=0.185$

And using the complement rule we find P(A') representing the probability that the female selected did not attend graduate school like this:

$P(A') = 1-P(A) = 1- \frac{124}{672}= \frac{137}{168}=0.815$

Two angles are complementary. The value of one angle is twice as that of the other one. Find the individual angle

aleksandrvk [35]

Answer:

60°

Step-by-step explanation:

Complementary angles both add up to 90°. Therefore if one angle is twice the other, then if we divide 90 by 3 then we get 30. Two parts of 30 is 60 plus the other 30 and we get 90. The individual angle is 60°and the other is 30°
