Answer:
5. 540°
Step-by-step explanation:
m<a + m<c = 180°
m<h + m<f = 180°
m<k + m<m = 180°
Then m<a + m<c + m<h + m<f + m<k + m<m = 180° x 3 = 540°
1. 1/3
2.1/3
3.3/36
this is because probability is equal to favourable outcome/total outcome. in this case, favourable outcome is the outcome that is asked in the question and total outcome is all the possibilities
At most means less than or equal to:
7 + x ≤ 20
you must substitute x in the equation given :)
examples:
when x is -2
therefore, y = 2(-2) + 3
y = -1
when x is 0
therefore, y = 2(0) + 3
y = 3
when x is 1
therefore, y = 2(1) + 3
y = 5
when x is 3
therefore, y = 2(3) + 3
y = 9
for (b) you only have to plot based on the table ;)
hope this helps
