Answer:
down
Step-by-step explanation:
Assuming this is for a parabola
a>0 the graph opens up
a < 0 the graph opens down
( negative is a frown)
Considering it's concept, it is found that the number of outcomes in the sample space is of 9.
<h3>What is the sample space of an experiment?</h3>
The sample space is the <u>set that contains all possible outcomes for an experiment</u>.
In this problem, there are 2 trials, each with 3 possible outcomes(red, blue or green), hence the <u>number of possible outcomes</u> is given by:
N = 3² = 9.

Answer:
See below
Step-by-step explanation:
the common ratio, r <1 so it CONVERGES (r = 1/2 in this series)
sum = a1 ( 1-r^n) / (1-r) = 1000(1-.5^10)/(1-1/2) = ~1998
for n= 30 this results in ~~2000
As it continues, the terms get smaller and smaller and the SUM converges on 2000.
Answer:
Graph C
Step-by-step explanation:
It is Graph C because the points are majorly curved, while the rest of the lines are linear because they are straight.
Hope this helps! :D

Answer:
Step-by-step explanation:
Given that angle A is in IV quadrant
So A/2 would be in II quadrant.
sin A = -1/3
cos A = 
(cos A is positive since in IV quadrant)
Using this we can find cos A/2
