Answer:
{ 3 }
Step-by-step explanation:
-30+9x=-0.5 |x-1| -2
from the graph, we can see that both curves intersect at (3,-3)⇒x=3
put x=3 in LHS&RHS
⇒LHS=-30+9(3)=-3
RHS=-0.5 |3-1|-2=
-1/2×2-2=-1-2=-3
so the answer will be 3..
hope it helps..
have a great day!!
Answer:
1 is biased, 2 isn't, 3 is biased, 4 isnt
Step-by-step explanation:
If you ask a question to people in a group who are already clearly for a certain topic then it is biased. For survey to not be biased, the people need to be chosen at random. Ask students what their favorite class is, or ask flight attendants where their favorite destination to travel to is. Dont use a group who has any relation to the survey at hand. Asking band students about funding for band is biased, as well as asking people who are at a SOCCER GAME what their favorite sport is.

Step-by-step explanation:
vertical angles are the opposite angles created by intersecting lines and are congruent. Vertical angles share only a vertex
Answer:
10
β
Step-by-step explanation:
We can find this two ways, first by seeing in the step after it, cosines are canceled out. Since you already have 10β on the next step, you can assume that (since only the cosines changed and the cosine next ot the blank was removed), the value is 10β.
You can also use double angle formulas from the previous step:
(sin(2β) = 2 sin(β) cos(β))and find that:
5 sin (2β) sin(β) = 5 * (2 sin(β) cos(β)) sin(β)) = (10 sin(β) sin(β)) cos(β) =
10β cos(β)
But since cos(β) is already present, we can see that the answer is 10β
6+10+3+8 = 27, so they played a total of 27 games
6/10 reduces to 3/5 for home games
