Answer:
Step-by-step explanation:
StartFraction 2 Over 5 EndFraction plus p equals StartFraction 4 Over 5 EndFraction plus StartFraction 3 Over 5 EndFraction
- 2/5 + p= 4/5 + 3/5p
- p - 3/5p = 4/5 - 2/5
- 2/5p = 2/5
- 2p = 2
- p = 1
Answer is 1
Answer: A:Yes
Step-by-step explanation:
This table shows a proportional relationship between the variables x and y.
Answer:
π/4 radians
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle (in radians).
Here, r = 8 inches and s = arc length = 2π inches. We need to find the central angle, Ф. The formula given above is s = rФ, or, equivalently,
Ф = s/r.
Here, the central angle is Ф = s/r = 2π/8, or π/4 radians.
The more observations you make the closer and closer the experimental probability will approach the theoretical probability. In this case the theoretical probability is:
P(HH)=(1/2)(1/2)=1/4
So in 105 trials one would expect to get two heads:
105(1/4)=26.25 times.
