Answer: 12 hours a week

Step-by-step explanation:

60/5 = 12

Since he plays chess 5 times the amount of time he sleeps, simply divide the amount of time he sleeps by 5.

Correct me if I am incorrect.

Mario claims that if the dinominator of a fraction is a prime number, then its decimal form is a repeting decimal. Do you agree?
vodomira [7]

Answer:

I do not agree because Mario's claim is not general.

Step-by-step explanation:

Prime numbers: These are a set of numbers that are divisible by 1 and itself only. Examples are: 2, 3, 5, 7. 11 etc.

And a  denominator is the divisor in a given fraction.

Considering the following fractions whose denominators are prime numbers:

\frac{2}{3} = 0.66666666...

\frac{1}{7} = 0.142857142

\frac{5}{11} = 0.45454545...

\frac{3}{13} = 0.23076923

\frac{1}{7} = 0.142857142

It could be observed that Mario's claim is not a general principle which is applicable to all fractions with a prime denominator. Thus, I do not agree with his claim.

Craig examines the effect of different genres of music, such as jazz, rock, rap, on task performance. Which type of measurement
ryzh [129]

Answer:

Nominal

Step-by-step explanation:

Data can be divided into 2 types:

  • Qualitative Data
  • Quantitative Data

Qualitative data represent some attribute or characteristic and cannot be measured or calculated. This type of data uses Nominal or Ordinal level of measurement.

Quantitative data is the data which can be measure or calculated. This type of data is expressed in Ratio or Interval scale.

Different genres of music represent an attribute, hence the data is Qualitative.  Qualitative data which can put into some order is at Ordinal scale of measurement, while if the data simply represent the name or attributes it would be at Nominal Level.

Different genres of music cannot be put into some order and are just names, hence the measurement scale would be Nominal.
