Answer:

x = 17

Step-by-step explanation:

Angle A and angle B are complementary.

Therefore,

(2x + 16)° + 40° = 90°

(2x + 16)° = 90° - 40°

(2x + 16)° = 50°

2x + 16 = 50

2x = 50 - 16

2x = 34

x = 34/2

x = 17

Liono4ka [1.6K]

Answer:

a. 0.4

b. Not independent.

Step-by-step explanation:

a. We use the probability table attached below for our calculations.

-the probability that an agreement is reached on both sides is obtained from the table:

P(Agreement)=\frac{400}{1000}\\\\\\=0.4

b. To determine whether the two events are independent, we compare the probabilities P(s)\times P(i) and P(s \ and \ i) where i denotes insurance and s denotes salaries:

P(s)\times P(i)=0.5\times 0.7\\\\=0.35\\\\\\P(s \ and \ i)=0.4

Two events are considered to be independent, if and only if:

P(A).P(B)=P(A\ and \ B)\\\\=>P(s).P(i)\neq P(s\ and\  i)

Hence, the events are not independent.
