The research department of a board game company surveyed some shoppers at a local mall. The team asked shoppers how often they read the newspaper, among other questions. Then the team played a memory card game with the shoppers. They recorded how many cards each shopper remembered. 1-3 cards 4-6 cards O times a week 8 9 1-2 times a week 15 10 What is the probability that a randomly selected shopper reads the newspaper 1-2 times a week or remembered 1-3 cards? Simplify any fractions​

step-by-step explanation: given equation a = h(b 1+b 2)

also we are given values of a, h and b 1 as :

a = 16, h = 4, and b 1 = 3.

in order to solve it for b 2, we need to plug the given values of   a, h and b 1 .

therefore, plugging values of   a, h and b 1   in given equation, we get

16 = 4( 3 + b 2)

first dividing both sides by 4, we get

4 = 3 + b 2

subtracting 3 from both sides, we get

4 -3 = 3 -3 + b 2

1 = b 2.

  answer:

  write 548 as 500 + 40 + 8. multiply each addend by 5. then add the three products to get 2,740.
