Answer:
The minimum score required for admission to the nearest whole number = 557
Step-by-step explanation:
We solve this using z score formula.
z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.
Top 30% of the candidates is a ranking that is equivalent to = 100 - 30% = 70th percentile.
The z score of 70th percentile = 0.524
Mean = 497
Standard deviation of 114.
Minimum score = raw score = ???
Hence:
0.524 = x - 497/114
Cross Multiply
0.524 × 114 = x - 497
59.736 = x - 497
x = 59.736 + 497
x = 556.736
The minimum score required for admission to the nearest whole number = 557
Given that,
The length of ribbon= 36 inch
We know, if Shelia wants to divide the ribbon in 5 equal parts, she needs to divide the length of the ribbon by 5.
So,
The length of the 5 equal parts of the ribbon= 36/5= 7.2 inch
But Shelia got each pieces length equals to 7 inches.
So, There is an error of (7.2-7) 0.2 inches in her calculation.

Answer: 29000 people went in 1981.
Step-by-step explanation:
Let x= Attendance in 1981.
Given: The average attendance of Everton football club fell by 7% in 1982.
Difference in attendance from 1981 to 1982 = 0.07x
If 2030 fewer people went to matches in 1982,
Hence, 29000 people went in 1981.
