A). They are supplementary angles meaning they add up to 180
So
B) (12x+8)+(3x+7)=180
12x+8+3x+7=180
15x+15=180
-15 -15
15x=165
15/15x=165/15
x=11

Angle 1 is
12x+8
12(11)+8
132+8
140
Therefore measure of angle 1 is 140°

Angle 2
3x+7
3(11)+7
33+7
40
Measure of angle 2 is 40°

ExtremeBDS [4]

Answer: 0.49668352

Step-by-step explanation:

Given : The unemployment rate : p = 20%= 0.20

Sample size : n =8

Let x be the binomial variable that represents the number of unemployed residents.

Binomial probability distribution formula : ^nC_xp^x(1-p)^x

The probability that at least two of the residents were unemployed :

P(x\geq2)=1-P(x

1-(^8C_0(0.2)^0(0.8)^8+^8C_1(0.2)^1(0.8)^7)

1-((1)(0.16777216)+(8)(0.2)(0.2097152))

1-(0.16777216+0.33554432)

1-(0.16777216+0.33554432)=1-0.50331648=0.49668352

Hence, Required probability =0.49668352
