The grades on a chemistry midterm at Loyola are roughly symmetric with μ = 67 μ=67mu, equals, 67 and σ = 5.5 σ=5.5sigma, equals, 5, point, 5. Tiffany scored 53 5353 on the exam. Find the z-score for Tiffany's exam grade. Round to two decimal places.

i leave the calculator work to you.

7. diameter 4 miles, circumference 4π miles

8. radius 0.2 miles, circumference 0.4π miles

[this is a bad problem because the actual radius of a car on the track is less than 0.2 miles so the answer is less than 0.4π miles]

9. radius 6 feet, circumference 12π feet

10. diameter 14 cm, circumference 14π cm

11. diameter 4.8 feet, circumference 4.8π feet

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
