In a survey of 250 people concerning how they obtain information about current events, 70 people read a newspaper each day, 130 watch news on television each day, and 30 read a newspaper and watch news on television each day. If a person is selected at random from the group surveyed, what is the (empirical) probability that the person does not either read a newspaper or watch news on television each day?

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35

step-by-step explanation:

assume that you have 3 different side lengths.   apply the pythagorean theorem here:   square each of the two shortest sides; call them a and b, so that their squares are a² and b².   also square the longest side, calling the result c².

now, if a² + b² = c² is true, the triangle is a right triangle; otherwise it is not a right triangle.
