Make n the subject of m= n² + 3
Andrej [43]

The n subject of m = n² + 3  is  n=\sqrt{m-3}

How is n made the subject of m = n² + 3 ?

m = n² + 3

n² = m- 3

n=\sqrt{m-3}

What does making n the subject mean?

  • To make n the subject of the formula or equation, we must rearrange the variables in the formula or equation to  have a single variable n that is equivalent to the other variables in the formula.
  • The equation is then rearranged such that each term containing n is placed on the same side of the equation.
  • If n appears in several words, factorization might be necessary.
  • Just one n needs to be displayed at the conclusion to make it the subject.
  • The result of square rooting a number or variable as an inverse operation may be positive or negative.

Suppose the test scores on an exam show a normal distribution with a mean of 82 and a standard deviation of
Zanzabum

Answer:

a) Between 74 and 90

b) 81.86% of the scores are between 78 and 90

Step-by-step explanation:

a) According to the Empirical Rule, in a normal distribution, 95% of the data are within 2 standard deviations of the mean. Therefore, the range that 95% of the scores fall in is between 82-4(2)=74 and 82+4(2)=90.

b) The percent of scores that are between 78 and 90 is: normalcdf(lower,upper,μ,σ) = normalcdf(78,90,82,4) = 0.8185946784 ≈ 0.8186, or about 81.86% of the scores.
