Alexandra [31]

Answer:

Interest rate is 5.25% a year.

Step-by-step explanation:

r = (1/54)((22252.5/18000) - 1) = 0.004375

r = 0.004375

Convert decimal to percentage

R = 0.004375 * 100 = 0.4375%/month

Calculate annual rate

0.4375%/month × 12 months/year = 5.25% per year.

Find the interior angle of a regular polygon which has 6 sides​
AveGali [126]

Answer:

120°.

Step-by-step explanation:

The sum of all interior angles in a polygon with n sides (n\in \mathbb{Z}, n \ge 3) is equal to (n - 2) \cdot 180^{\circ}. (Credit: Mathsisfun.)

The polygon here has 6 sides. n = 6. Its interior angles shall add up to (6 - 2) \times 180^{\circ} = 720^{\circ}.

Consider the properties of a regular polygon. (Credit: Mathsisfun.)

  • All sides in a regular polygon are equal in length.
  • All angles in a regular polygon are also equal.

There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be

\displaystyle \frac{1}{6}\times 720^{\circ} = 120^{\circ}.

IRINA_888 [86]

Answer: 0.206

Step-by-step explanation: the probability of employees that needs corrective shoes are =8%= 8/100 = 0.08

Probability of employees that needs major dental work = 15% = 15/100 = 0.15

Probability of employees that needs both corrective shoes and dental work = 3% = 3/100 = 0.03

The probability that an employee will need either corrective shoes or major dental work = (Probability an employee will need correct shoes and not need dental work) or (probability that an employee will need dental work or not corrective shoes)

Probability of employee not needing corrective shoes = 1 - 0.08 = 0.92

Probability of employee not needing dental work = 1 - 0.15 = 0.85

The probability that an employee will need either corrective shoes or major dental work = (0.08×0.85) + (0.15×0.92) = 0.068 + 0.138 = 0.206 = 20.6%

The probability that an employee will need either corrective shoes or dental work = 0.206.

Please note that the word "either" implies that we must choose one of the two options (corrective shoes or dental work) and not both.
