Step-by-step explanation:
Number 1
180° = x + 70° + 55° + 30°
180° = x + 155°
x = 180° - 155°
x = 25°
Number 2
x° = 93°
y° = 47°
z° = 180° - 47° - 93°
z° = 180° - 140°
z° = 40°

Answer:
a=223.57
c=181.43
Step-by-step explanation:
a=405-c
substitute for a in the equation :
12a+5c=3590
12(405-c)+5c=3590
4860-12c+5c=3590
-7c=3590-4860
-7c=-1270
c=1270/7=181.43
a=405-1270/7
a=1565/7=223.57
The probability that the student chosen at random is not a male that had a A grade is 0.85.
<h3>What is the probability?</h3>
Probability determines the odds that an event would happen. The probability the event occurs is 1 and the probability that the event does not occur is 0.
The probability = (number of students - males who had a A grade) / total number of students
(59 - 9) / 59 = 50 / 59 = 0.85
