Answer:
<u>96 cm ²</u>
Step-by-step explanation:
A = bh (12 x 8)
12 x 8 = 96
Answer:
The mean absolute deviation = 3.5°F
Step-by-step explanation:
The sum of the given temperatures, ∑T, is found as follows;
∑T = 66°F + 57°F + 61°F + 65°F + 54°F + 62°F + 59°F + 56°F = 480°F
The number of days, n, over which the temperature was tracked = 8 days
Therefore, the mean, , of the data set = ∑T/n = 480°F/8 = 60°F
The mean absolute deviation is given by the following formula;
Therefore, we have;
66 - 60 = = 6
57 - 60 = = 3
61 - 60 = = 1
65 - 60 = = 5
54 - 60 = = 6
62 - 60 = = 2
59 - 60 = = 1
56 - 60 = = 4
The mean absolute deviation is therefore;
The mean absolute deviation = (6 + 3 + 1 + 5 + 6 + 2 + 1 + 4)/8 = 3.5°F.
Ok,
divide by 2 on both sides...
So X = 3/8!
Answer:
Step-by-step explanation:
<u>Possible roots from point F to Ball 3 are:</u>
- F ⇒ Ball2 ⇒ F ⇒ Ball1 ⇒ Ball3
- F ⇒ Ball2 ⇒ Ball1 ⇒ Ball3
- F ⇒ Ball1 ⇒ Ball2 ⇒ Ball3
Its not difficult to see the shortest root the the last one.
<u>Let's find each part of the total distance:</u>
- F ⇒ Ball1 = 9 yds
- Ball1 ⇒ Ball2 = yds
- Ball2 ⇒ Ball3 = yds
<u>Total distance is:</u>
