sin^{-1}\frac{1}{2}\\\frac{\pi}{6}+2\pi n

A sine function will have a value of 1/2 infinity times. However, on the interval of a single period, a sine function will have a value of 1/2 one time.

That depends on what range of angles you explore.

Through the first circle's worth (360 degrees), the sine function
has the value of 1/2 twice ... at 30 degrees and at 150 degrees.

Find five numbers that have a mean of 10 and a median of 12.
Zigmanuir [339]

Answer:

There are infinitely many solutions. Start with five data, in size order: a < b < c < d < e. Then c=11, the median. To get the mode of 12, we must have d=e=12. Thus far, we have (a+b+11+24)/5 = 10 the mean. But now we have run out of requirements, and we still have two unknowns. They satisfy a+b+35 = 50. Thus, pick any two values a not equal to b that add to 15 and are both less than 11.

The full set of solutions are points (a,b) run along a line joining the points (4,11) and (11,4) on graph paper, except (7.5, 7.5) and the endpoints. That would make competing modes. Try a=5.6 and b = 9.4 for instance!

32. You plan to purchase items for $4000 and will finance the cost with a fixed installment
Paul [167]

Answer:

Amount of finance charge = $800

Interest rate = 5% per year

Step-by-step explanation:

Given:

Cost of item = $4,000

Per month payment = $100

Number of month = 48 month = 48 /12 = 4 year

Find:

Amount of finance charge

Interest rate

Computtaion:

Total amount pay = 100 x 48

Total amount pay = $4,800

Amount of finance charge = Total amount pay - Cost of item

Amount of finance charge = 4,800 - 4,000

Amount of finance charge = $800

Interest = P x r x T

800 = 4,000 x r x 4

800 = 16,000 x r

Interest rate = 5% per year
