00:00:02.330 --> 00:00:06.759 A:middle L:90%
so looking at the graph can gather that the maximum
2
00:00:06.759 --> 00:00:10.949 A:middle L:90%
temperature happens in July, which is the seventh month
3
00:00:11.279 --> 00:00:15.779 A:middle L:90%
, and that maximum temperatures approximately 815. And then
4
00:00:15.789 --> 00:00:18.620 A:middle L:90%
the minimum temperature happens in January, which is the
5
00:00:18.620 --> 00:00:23.839 A:middle L:90%
first month and that minimum temperatures approximately 65. So
6
00:00:23.839 --> 00:00:27.000 A:middle L:90%
from here we can calculate the AMP acute A,
7
00:00:27.010 --> 00:00:32.600 A:middle L:90%
which is maximum temperature minus the minimum temperature divided by
8
00:00:32.600 --> 00:00:38.570 A:middle L:90%
two. So that would be 115 minus 65 divided
9
00:00:38.579 --> 00:00:43.140 A:middle L:90%
by two. And that's equal to 25 since we're
10
00:00:43.140 --> 00:00:45.490 A:middle L:90%
talking about Dempster change or a year, so the
11
00:00:45.490 --> 00:00:48.899 A:middle L:90%
period is 12. From there we can Catholic be
12
00:00:48.899 --> 00:00:51.469 A:middle L:90%
, which is to pine divided by the period.
13
00:00:51.820 --> 00:00:55.700 A:middle L:90%
So to pine, divided by 12 gives I over
14
00:00:55.920 --> 00:01:00.170 A:middle L:90%
six. Now, next thing we're gonna do is
15
00:01:00.170 --> 00:01:07.370 A:middle L:90%
calculate the mean temperature and the mean temperature is the
16
00:01:07.739 --> 00:01:14.459 A:middle L:90%
D vertical shift, which is maximum plus the minimum
17
00:01:15.540 --> 00:01:23.359 A:middle L:90%
divided by two so backward people 215 plus 65 divided
18
00:01:23.370 --> 00:01:26.540 A:middle L:90%
by two. And that's equal to 90. So
19
00:01:26.540 --> 00:01:29.680 A:middle L:90%
now we can grow. And then when does the
20
00:01:29.680 --> 00:01:34.099 A:middle L:90%
mean temperature first occur? So the mean temperature first
21
00:01:34.109 --> 00:01:44.400 A:middle L:90%
up occurs, and April and April is the fourth
22
00:01:44.400 --> 00:01:47.060 A:middle L:90%
month. So that would be teams equal to four
23
00:01:47.209 --> 00:01:49.120 A:middle L:90%
. So we can write the equation. Now.
24
00:01:49.120 --> 00:01:53.909 A:middle L:90%
Why is equal to 25 sign off high over six
25
00:01:55.489 --> 00:02:01.540 A:middle L:90%
times T minus four plus 90 Or we have why
26
00:02:01.540 --> 00:02:09.150 A:middle L:90%
is equal to 25 Sign off high over six T
27
00:02:09.310 --> 00:02:15.550 A:middle L:90%
minus two pi over fee plus 19.
