Answer to Problem 11PPS
D’s mean practice time is 21 mins 54 secs.
Explanation of Solution
Given information:D’s practice times (m: s),
20:45, 21:30, 21:15, 22:32, 21:40
Formula used:Mean formula is,
Mean=
Where, n=total number of terms,
Calculation:
Convert time in seconds,
Now, Practice time is 1245,1290, 1275, 1352, 1300
Substituting the values in mean formula,
So,
On solving,
Hence, the timing of D’s practice is 1292.4 seconds.
Converting seconds into minutes,
Cross multiplying,
For 1292.4 seconds,
On solving,
That is, 21 mins 54 secs.
Hence, D’s mean practice time is 21 mins 54 secs.
b.
To calculate D’s race time.

Answer to Problem 11PPS
D’s race time is 1260 seconds
Explanation of Solution
Given:
Completion time of race was 30secs less than her median time.
Formula used:Median’s formula is,
Median=
Calculation:
Re-arranging her practice time in ascending order,
1245, 1275, 1290, 1300, 1352
Number of terms (n) =5
Substituting the values in median formula,
So,
On solving,
Substituting the value of 3rd term,
Hence, her race timings are,
Substituting the value,
On solving,
Hence, D’s race timings are 1260 seconds

Enterarrow_forwardYou are given a plane Π in R3 defined by two vectors, p1 and p2, and a subspace W in R3 spanned by twovectors, w1 and w2. Your task is to project the plane Π onto the subspace W.First, answer the question of what the projection matrix is that projects onto the subspace W and how toapply it to find the desired projection. Second, approach the task in a different way by using the Gram-Schmidtmethod to find an orthonormal basis for subspace W, before then using the resulting basis vectors for theprojection.
