Answer:
64/200 times the spinner will land on vowel
Step-by-step explanation:
On the table, the chart says 10 times for A and 6 times for E. This means that the experimental probability for rolling a vowel in a trial of 50 rolls is 16/50.
The next step is create equal ratios. 16/50 = x/200. 50 times <u>4 </u> is 200 so 16 times <u>4 </u> is 64.
Use the substitution method
(9,90) y= 10x
90= 10(9)
90= 90

Answer:
15.0
Step-by-step explanation:
Let's start by looking at triangle ORQ. Since RQ is tangent to the circle, we know that angle ∠ORQ is 90°. Then, since OR is equivalent to the radius of 5, RQ is 5√3, and side OQ is clearly larger than RQ, we can identify this as a 90-60-30 degree triangle. This makes side OQ have a length of 10, and angle ∠QOR, opposite of the second largest side, has the second largest angle of 60°, leaving ∠OQR with an angle of 30°.
The formula for the chord length is 2r*sin(c/2), with c being the angle between the two points on the circle (in this case, ∠QOR=∠NOR).. Our radius is 5, so the length of chord NR is 2*5*sin(60/2)=5, making our answer 5(ON)+5(OR)+5(RN)
