The following table shows each of Haruka's final exam scores last semester. Final exam Score on a 100100100-point scale Astronom
1 answer:
The mean calculated shows that the Chemistry score will be 87.
<h3>How to calculate the score?</h3>From the information given, the total scores will be:
= 84 × 4
= 336
The addition of the scores given will be:
= 72 + 85 + 92
= 249
The Chemistry score will be:
= 336 - 249
= 87
<u>Complete question:</u>
If the mean of the data set is 84 points, find Harukas final exam score in Chemistry.

Answer:
Orion's belt width is 184 light years
Step-by-step explanation:
So we want to find the distance between Alnitak and Mintaka, which is the Orions belts
Let the distance between the Alnitak and Mintaka be x,
Then applying cosine
c²=a²+b²—2•a•b•Cosθ
The triangle is formed by the 736 light-years and 915 light years
Artemis from Alnitak is
a = 736lightyear
Artemis from Mintaka is
b = 915 light year
The angle between Alnitak and Mintaka is θ=3°
Then,
Applying the cosine rule
c²=a²+b²—2•a•b•Cosθ
c² =736² + 915² - 2×, 736×915×Cos3
c² = 541,696 + 837,225 - 1,345,034.1477702404
c² = 33,886.85222975954
c = √33,886.85222975954
c = 184.0838184897 light years
c = 184.08 light years
So, to the nearest light year, Orion's belt width is 184 light years
