Darina [25.2K]

Answer:

The answer to your question is  0.83 or 83%

Step-by-step explanation:

Data

5 red marbles

10 blue marbles

14 yellow marbles

Process

1.- Calculate the total amount of marbles

    Total amount = 5 red + 10 blue + 14 yellow

     Total amount = 29 marbles

2.- Calculate the amount of marbles that are not red

     No red marbles = 10 + 14

                                = 24 marbles

3.- Calculate the probability

Probability of not pulling a red marble = \frac{no red marble}{total amount of marbles}

Probability of not pulling a red marble = \frac{24}{29} = 0.83 or 83%

madam [21]
The first side is 10 inches
the side parallel to this is (10×2)= 20 inches
Height is half the length=1/2×20=10 inches
The area of trapezium is given by:
Area=1/2×h×(a+b)
where a and b are the sides, h is the height. Thus the area will be:
Area=1/2×10×(20+10)
=1/2×10×30
=150 sq. inches

A) .10 * 15 d + .25 * 25 = 7.75
A) 1.50 + 6.25 = 7.75

Correct!!
