Answer:
True, since 1 is 1/1, which is 100%
<em>Hope that helps! :)</em>
Step-by-step explanation:
1.
the angle should add up to 360
so
360-110-90=160
that is the answer
2.
the angle has to add up to 90
so
90-57=33
-54 because -5(9)= -45 and -9(1)=-9 so -45-9=-54
Answer:
The sample space of the game is: S = {1, 2, 3, 4, 5, 6}.
Step-by-step explanation:
Sample space is a set of all possible outcomes of an experiment.
Consider a few example:
- Consider the experiment of tossing a coin. The sample space of this experiment consists of only two outcomes, i.e. Heads (H) and Tails (T).
- Consider the experiment of rolling a fair six-sided die. The sample space of this experiment consists of six outcomes, i.e. faces 1, 2, 3, 4, 5 and 6.
- Consider the experiment of selecting a card from a pack of 52 cards. The sample space of this experiment consists of 52 distinct outcomes.
The probability of all the outcomes in a sample space always sum up to 1.
Thus, fulfilling the condition of a valid sample space.
In this case, a game is played by spinning a pointer of a spinner with six equal-sized sections.
So, the pointer has 6 possible sections to land.
The pointer lands on any of the 6 sections with same probability, i.e. .
The sample space of the experiment is:
S = {1, 2, 3, 4, 5, 6}
Answer:
Step-by-step explanation:
put x=1
1 ) 1 7 7 -15
| 1 8 15
----------------
1 8 15 | 0
so x-1 is a factor.
x²+8x+15=0
x²+3x+5x+15=0
x(x+3)+5(x+3)=0
(x+3)(x+5)=0
so x-1,x+3,x+5 are factors.
