The grades on a math midterm at Springer are roughly symmetric with \mu = 68μ=68mu, equals, 68 and \sigma = 4.5σ=4.5sigma, equals, 4, point, 5. Brandon scored 717171 on the exam. Find the z-score for Brandon's exam grade. Round to two decimal places.

yes. we do proportions in probabilities.

80π/3 or about 83.775

step-by-step explanation:

since a cone is 1/3 of a cylinder, we need to find the base's area. since area = πr^2, we get 16π. then, multiplying this by 5, we get 80π. dividing by 3, since the cone's volume is 1/3 of that of a cylinder's, we get 80π/3.

hope this !
