Answer: A. x= -50
Step-by-step explanation:
1/5x = -10
<u> 1 </u>= -10
5x
1.1 = 5x. (-10)
- 50x
x= -50
Answer: Around 50 times.
Step-by-step explanation:
If the spinner is fair, then each number should have the same probability, that is P = 1/5 = 0.20 for each of the numbers.
Now, we know that we have 5 groups, and each group spins 50 times (so we have a total of 5*50 = 250 spins)
Then we can expect to see the number 3 around:
0.20*150 = 50
In the right triangle, one of the angles has measure 60 deg, so the remaining angle has measure 30 deg. In such a 30-60-90 triangle, the sides occur in a ratio of 1 to
to 2 (shorter leg to longer leg to hypotenuse). This means


making the answer C.
