Answer:
36x
Step-by-step explanation:
18x / 19 = ? / 57
(18x * 3) / (19 * 3) = ? / 57
You multiply by 3 in both the numerator and the denominator.
36x / 57 = ? / 57
After you multiply, your answer equals 36x.
? = 36x
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.
