A sample of 15 female collegiate golfers was selected and the clubhead velocity (km/hr) while swinging a driver was determined for each one, resulting in the following data ("Hip Rotational Velocities During the Full Golf Swing," J. of Sports Science and Medicine, 2009: 296–299): 69.0 69.7 72.7 80.3 81.0
85.0 86.0 86.3 86.7 87.7
89.3 90.7 91.0 92.5 93.0
The corresponding z percentiles are
-1.83 -1.28 -0.97 -0.73 -0.52
-0.34 -0.17 0.0 0.17 0.34
0.52 0.73 0.97 1.28 1.83

step-by-step explanation:

the diameter is 16 cm. are you a teacher?

step-by-step explanation:

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.

answer: the resulting cross section is a rectangle. solution: a plane parallel to the base of a triangular prism will intersect a cross section that is the same shape as its bases. so the cross section is a triangle.
