Step-by-step explanation: Probability indicates that the event <u><em>WILL </em></u>occur. Odds (in ratio) on the other hand indicates and reflects a prospect that there will be a non-occurrence of the events. It all depends on the connotation.
Answer:
5x²- 1.8
Step-by-step explanation:
roots are -3 and 3, put them in brackets
(x - 3)(x + 3)
x² + 3x - 3x - 9
x² - 9
5x = -9
x = -1.8
5x² - 1.8
just to check:
5x² - 1.8
x² - 9
(x - 3)(x - 3)
x = -3 and 3.
Answer:
△PQR is not congruent to △XYZ because there is no sequence of rigid motions that maps △PQR to △XYZ.
Step-by-step explanation:
We can see from the diagram that XYZ is not the same size as PQR. This means there is no series of rigid motions, which preserve segment length, that maps PQR to XYZ.
Answer:
B
Step-by-step explanation:
Using the trig. identity
cos x =
Given
secx = - , then
cos x = - × = - = - , thus
x = (- ) = → B
