Scores from an exam are normally distributed with a mean of 85 and a standard deviation of 5. Suppose 188 students take the exam
charle [14.2K]

The mean is \mu=85 and standard deviation is \sigma=5. Then the variable X\sim N(85,5).

Use substitution Z=\dfrac{X-\mu}{\sigma}=\dfrac{X-85}{5}, then the variable Z\sim N(0,1).

The probability Pr(X>80) can be calculated in the following way:

for X=80, Z=\dfrac{80-85}{5} =-1 and Pr(X>80)=Pr(Z>-1). From the diagram Pr(Z>-1)=0.34+0.34+0.135+0.025=0.84.

Conclusion: if 188 students take the exam, then 188·0.84=157.92 (157) would receive a score above 80

We have to determine the constant in the equation, which shows how Eric can calculate his profit ( y ). He sells each shirt for $4 and he has total expenses: $100 + $10 = $110. So the equation for profit is: y = 4 x - 100. In this equation y is dependent variable, x is independent variable, 4 is coefficient and - 100 is the constant. A constant is a number ( a quantity that does not vary ). Answer: D ) - 110<span>.</span>
