The correct answer is y=2/3x
To find the slope you use rise over run so you take one dot (2,-5) and go up 2 units so that it would get one the same line as the other dot (5,-3) and then go to the right 3 units to get you to the exact spot that the dot is
Answer:
0.68 : 0.32
Step-by-step explanation:
the probability of all the outcomes of an event is always 1 .
if P(E) = 0.32,
P(E') = 1 - 0.32
= 0.68
N.B that P(E') is the same as P( not E ).
since your answer should be given in the ratio form, as the odds against E ( probability not E : probability E),
P(E') : P(E)
0.68 : 0.32

Answer:
Option A.
Step-by-step explanation:
It is given secθ = - ![\frac{4}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B4%7D%7B3%7D)
then cosθ = -![\frac{3}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B3%7D%7B4%7D)
Now we know the identity
sinθ = ![\sqrt{1-cos^{2}\theta }](https://tex.z-dn.net/?f=%5Csqrt%7B1-cos%5E%7B2%7D%5Ctheta%20%7D)
= ![\sqrt{1-(-\frac{3}{4} )^{2}}](https://tex.z-dn.net/?f=%5Csqrt%7B1-%28-%5Cfrac%7B3%7D%7B4%7D%20%29%5E%7B2%7D%7D)
= ![\frac{\sqrt{7} }{4}](https://tex.z-dn.net/?f=%5Cfrac%7B%5Csqrt%7B7%7D%20%7D%7B4%7D)
Now sin2θ = 2sinθcosθ
Now we put the values of cosine and sine in the formula
sin2θ = 2×(-
)(
)
= -![\frac{3\sqrt{7}}{8}](https://tex.z-dn.net/?f=%5Cfrac%7B3%5Csqrt%7B7%7D%7D%7B8%7D)
Therefore, option A. is the answer.
