Probability of compound events:
P ( A and B ) = P ( A ) · P ( B )
P ( A ) = 0.6
P ( B ) = 0.3
P ( A and B ) = 0.6 · 0.3 = 0.18  ( or 18 % )

type the correct answer in the box. if the measure of angle θis 7⁢π6. the equivalent measurement in degrees is °.
Travka [436]

If the measure of an angle "θ" is 7⁢(π/6), then it's equivalent measurement in degrees is 210°.

As per question statement, we have an angle "θ" whose measurement in radians is 7⁢(π/6). We have to convert this radians into its equivalent measurement in degrees. Thus, to solve this question, we will have need to know the relation between radians and degrees, which goes as,

("π" Radian = 180°).

Then, we will apply unitary method to our provided data and use the above-mentioned relation to obtain our desired answer, i.e.,

π Radian = 180°,

then, 7π Radian = (180*7)°,

Then, 7⁢(π/6) Radian = \frac{(180*7)}{6} =(30*7)=210°.

  • Radian: This is an unit of angle, equal to an angle at the center of a circle whose arc is equal in length to the radius.
  • Degrees: This is another unit of measurement of angles, one unit of this being equal to one three-hundred-and-sixtieth of the circumference of a circle.

3. The following data was collected from a simple random sample from a process (an infinite population). 13 15 14 16 12 a. The p
SVETLANKA909090 [29]

Answer:

14

Step-by-step explanation:

Given the data:

13 15 14 16 12

The point estimate of the population mean will be :

ΣX/ n

X = Given data points

N = sample size

ΣX = (13 + 15 + 14 + 16 + 12) = 70

N = 5

Hence,

ΣX/ N = 70 / 5

Point estimate of population mean = 14
