The total fabric used for headband and wristband of a player was: 27.84 inches
Step-by-step explanation:
The question will be solved step by step.
So,
Total ribbon used for headbands = 883.68 inches
Total number of people for whom headbands were made = 46 players + 2 coaches = 48 inches
so the headband for one person will use fabric:
Then
Total fabric used for wristbands = 433.78 inches
Total players = 46
Total fabric for one player = 18.41 + 9.43 = 27.84 inches
Hence,
The total fabric used for headband and wristband of a player was: 27.84 inches

Answer:
0.23
Step-by-step explanation:
Given the data:
____(x) __(y)__(x - m1) /s1 ___(y-m2) /s2
1 ___6 ___8__ - 0.2 _______0.625
2 __5 ___ 5__ - 0.7________ - 1.25
3 __9____6__ 1.3 ________ - 0.625
4__ 4____ 7__ - 1.2 ______ 0
5__ 8 ____9 _ 0.8 _______ 1.25
For English :
Mean score(m1) = 6.4
Standard deviation (s1) = 2.0
For Science :
Mean score (m2) = 7.0
Standard deviation (s2) = 1.6
n = number of observations = 5
Correlation Coefficient (r) :
r = 1/(n - 1) Σ[((X - m1) / s1) * ((Y - m2) /s2)]
(-0. 2 * 0.625) + (-0.7 * - 1.25) + (1.3 * - 0.625) + (-1.2 * 0) + (0.8 * 1.25) = 0.9375
r = 0.9375/(5-1)
= 0.234
= 0.23
Divide d by 2 to get r. use the formula C=(pi)d to get C. using this formula, C should equal approximately 12.57 in. and r=2
Step-by-step explanation:
