Answer:
49 red marbles
Step-by-step explanation:
There is a bag with only red marbles and blue marbles.
We are told in the question that:
The probability of randomly choosing a blue marble is 2/9 . There are 63 marbles in total in the bag
Hence: since
P(Blue marbles) = 2/9
Hence,
The number of blue marbles = 63 ÷ 9
= 7
Hence:
2 × 7/9 × 7 = 14/63
Hence, the number of blue marbles = 14 blue marbles
The number of red marbles bus calculated as:
63 - 14 blue marbles
= 49 red marbles
Answer:
Option c): Less than 50
Step-by-step explanation:
By extending the grids for the graph to the right and a bit down, by understanding that the three points shown seem to behave like a straight line, and keeping the line (represented in green in the attached image) as predictive for the future, we can say that when the look at the grid-point that represents x = '20, the value for the vertical coordinate must be between 40 and 50 - definitely below 50, as suggested by option c).
This point in question is pictured in red in the attached image.
