There is a bag with only red marbles and blue marbles. The probability of randomly choosing a blue marble is 2/9 . There are 63
Verdich [7]

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

maxonik [38]

Assuming your question is how much farther has Horse A traveled than Horse B.

So after 5 seconds, Horse A already traveled 160 feet.

While Horse B, after 5 seconds traveled 140 feet.

So the difference is 20 feet.

Which of the following statements have the same result? Explain each step in solving each one.. . I f(3) when f(x) = 2x + 2. II
zhuklara [117]
F(x) = 2x + 2.....find f(3)
f(3) = 2(3) + 2
f(3) = 6 + 2
f(3) = 8

f(x) = (3x - 4)/5....find f^-1(4)
y = (3x - 4)/5...swap the variables
x = (3y - 4)/5 ...solve for y
5x = 3y - 4
5x + 4 = 3y
(5x + 4)/3 = y
f^-1(x) = (5x + 4)/3.....for f(4)
f(4) = (5(4) + 4)/3
f(4) = (20 + 4)/3
f(4) = 24/3
f(4) = 8

y + 10 = 2y + 1
y - 2y = 1 - 10
-y = -9
y = 9

so 1 and 2 have the same result...8
