An arc is 6.5 cm long and it subtends a central angle of 45 degrees. Find the radius of the circle.
Orlov [11]
Arc length = radius * central angle (measured in radians)
There are <span> <span> <span> 57.2957795131 </span> </span> </span> degrees per radian so
45 degrees = (45 / <span> <span> <span> 57.2957795131) = </span></span></span> <span> <span> <span> 0.7853981634 </span> </span> </span> radians<span><span> </span> </span>
radius = arc length / central angle (radians)
radius = 6.5 / <span> <span> 0.7853981634 </span> </span> radians = <span> <span> <span> 8.2760570408 </span> </span> </span> cm

A binomial event has n = 50 trials. The probability of success for each trial is 0.60. Let x be the number of successes of the e
babunello [35]

Answer:

30 and 3.4641

Step-by-step explanation:

The mean of a binomial distribution is:

μ = np

And the standard deviation of a binomial distribution is:

σ = √(npq)

Here, n = 50, p = 0.60, and q = 0.40.

μ = np = 50 × 0.60 = 30

σ = √(npq) = √(50 × 0.60 × 0.40) = 3.4641
