Answer:
x = 33
<C = 81
Step-by-step explanation:
The sum of the angles of a triangle add to 180
x+ 2x+ 2x+15 = 180
Combine like terms
5x+15 = 180
Subtract 15 from each side
5x +15-15 =180-15
5x = 165
Divide by 5
5x/5 =165/5
x = 33
<C = 2x+15 = 2(33)+15 = 66+15 = 81
Answer:
2.5cm^2
Step-by-step explanation:
so diameter is basically radius*2...to find radius(since area of circle is pi*r^2 we need to divide diameter by 2)
so 1.8/2=0.9
now,
pi*0.9^2
pi*0.81
2.5 cm^2
Answer:
Complete the table :
Likes hamburgers Does not like hamburgers Total
Likes burritos 29 41 70
Does not like burritos 81 54 135
Total 110 95 205
54 do not like both hamburgers and burritos
Hence % = (54/205) * 100 = 26.34 %
marginal relative frequency of all customers that like hamburgers
= 110/205
= 22/41
