Answer: 0.00923521

Step-by-step explanation:

Given : The probability U.S households play video or computer games=69%=0.69

here, the probability of each U.S household play video or computer games is fixed as 0.69

Then, the probability of each U.S household not play video or computer games= 1-0.69=0.31

For independent events the probability of their intersection is product of probability of each event.

Now, the probability that none play video/computer games will be :-

(0.31)^4=0.00923521

05.02)In the figure below, angle y and angle x form vertical angles. Angle y forms a straight line with the 60° angle and the 70
lesya692 [45]

Considering the situation described, the measure of angle x is of 60º.

<h3>What is the measure of angle x?</h3>

Researching this problem on the internet, we have that a 180º ray is bisected into two parts, each of 90º.

  • The first part has angles of 70º and y.
  • The second part has angles of 60º and x.

Due to the bisection, angles 60º and x are complementary, that is, they add up to 90º, hence:

60º + x = 90º

x = 30º.

The measure of angle x is of 60º.
