Answer: , where d= distance that Kiran walks in t minutes.
Step-by-step explanation:
Given: Kiran walked at a constant speed.
He walked 1 mile in 15 minutes.
The, distance walked by Kiran in 1 minute = mile
The distance that Kiran walks in t minutes = miles
If d= distance that Kiran walks in t minutes
The required equation:
Answer:
Standard deviation = 14.064
Step-by-step explanation:
We are given the following data;
X X -
20 20 - 46 = -26 676
23 23 - 46 = - 23 529
32 32 - 46 = -14 196
36 36 - 46 = -10 100
41 41 - 46 = -5 25
43 43 - 46 = -3 9
44 44 - 46 = -2 4
45 45 - 46 = -1 1
47 47 - 46 = 1 1
54 54 - 46 = 8 64
55 55 - 46 = 9 81
59 59 - 46 = 13 169
61 61 - 46 = 15 225
63 63 - 46 = 17 289
66 66 - 46 = 20 <u> 400 </u>
<u>= 2769 </u>
Firstly we will calculate Mean, =
= 45.93 ≈ 46
Now, Standard deviation formula is given by;
s = =
= 14.064 .
Answer:
C
Step-by-step explanation:
using the cosine ratio to find p
cos 45° = =
cross- multiplying gives
p × cos45° = 6 → [ cos 45° = ]
p × = 6
multiply both sides by
⇒ p = 6 ( third option on list )
