Answer:

x = 50

Step-by-step explanation:

Given

(x + 10) + (2x + 20) = 180 ( remove the parenthesis )

x + 10 + 2x + 20 = 180, that is

3x + 30 = 180 ( subtract 30 from both sides )

3x = 150 ( divide both sides by 3 )

x = 50

Answer:

x°=50°

Step-by-step explanation:

(x+10)°+(2x+20)°=180° (remove parenthesis)

x°+10°+2x°+20°=180°

x°+2x°+10°+20°=180° (addition of variable with variable and constant with constant)

3x°+30°=180°

3x°=180°-30° (on the other side of equality 30 became negative)

3x°=150°

x°=150°÷3° (division by 3)

x°=50°

In a certain town, 22% of voters favor the construction of a new hospital. For groups of 21 voters, find the variance for the nu
mixas84 [53]

Answer:

Variance = 3.6 voteres

Step-by-step explanation:

Probability of favour voters, P = 0.22

Total number of voters, n = 21

The probability of voters who are in not favour of new hospital construction = 1  - P

The probability of voters who are in not favour of new hospital construction = 1  - 0.22

The probability of voters who are in not favour of new hospital construction, P* = 0.78

Variance = n x p* x (1 - p*)

Variance = 21 x 0.78 x 0.22

Variance = 3.6 voters
