Answer:
x = 10°
y = 35°
Step-by-step explanation:
9x + 20 + 7x = 180 (supplementary angles)
16x = 180 - 20
16x = 160
x = 10°
2y = 7x (
opposite angles)
2y = 70
y = 35°
3.8+7.6+9.3+31+43+54+62+89+107+119+123+127=775.7
775.7/12=64.64166666666667
So the mean is 64.64

Answer:
x = 11
Step-by-step explanation:
The Frequency column has to total 50 ( number of rolls on dice )
Thus total the given frequencies and equate to 50, that is
12 + 8 + 7 + 3 + 9 + x = 50
39 + x = 50 ( subtract 39 from both sides )
x = 11
