Answer:
(0 ; 3)
Step-by-step explanation:
hello :
the midpoint of the line segment is : ((-2+2)/2 ;(-2+8)/2 )
(0 ; 3)
Answer:
- P(Yellow)=0.25
- P(Not Red)=0.65
Step-by-step explanation:
P(Red)=0.35
P(Green)=0.4
(a)Since there are three colours inside the bag
P(Red)+P(Green)+P(Yellow)=1
0.35+0.4+P(Yellow)=1
P(Yellow)=1-(0.35+0.4)
P(Yellow)=0.25
(b) In probability, the sum of an event and its complement is 1.
Therefore:
P(Red)+P(Not Red)=1
0.35+P(Not Red)=1
P(Not Red)=1-0.35
P(Not Red)=0.65
<span>We need to calculate noon sun angle. Noon sun angle is an angle at which sun-rays fall at noon on a given date.
</span>On September 22, the sun’s rays form a 90° angle at noon at the equator.
Formula for calculating noon sun angle is:
Noon_sun_angle = 90° - Zenith angle
We have complementary angles so we need to substract zenith angle from 90°.
The zenith angle is the distance between subsolar point (point where sun is at 90°) and the latitude of an observer. In our case this angle will have same value as latitude because subsolar point is at equator 0°. If our latitude and subsolar point are at same hemisphere we substract values. Otherwise we add values.
New Orleans, USA
Latitude = 30°
Noon_sun_angle = 90° - 30° = 60°
Helsinki, Finland
Latitude = 60°
Noon_sun_angle = 90° - 60° = 30°
The angle is going to be a 65° angle
