A Jar Contains 8 Red Marbles, 6 Blue Ones, And 6 Yellow Ones. One Marble Is Chosen At Random. The Color

Answers

Answer 1

Answer:

Step-by-step explanation:

Comment

The theoretical probabilities are

Red: 8/20 = 0.4

Blue:6/20 = 0.3

yellow:6/20 = 0.3

The experimental Probabilities are

Red: 11/40 = 0.275

blue: 11/40 = 0.275

Yellow: 18/40=0.45

Both probabilities add to 1 as they should

The yellow is the highest disproportionate answer and it really shouldn't be. If anything it should be red. (0.45 > 0.4 comparing yellow experimental with red theoretical. The yellow is way more than it should be)

The number of trials is double the number of marbles in the jar. The number of trials would be double for each color in the jar. Both blanks are double.

MEDA

Answers

The expression that expresses all possible lengths of segment AB is 27 < AB < 81. The correct option is the second option 27 < AB < 81

Properties of a triangle

From the question, we are to determine the expression that expresses all possible lengths of segment AB

From one of the properties of a triangle,

The third side of any triangle is greater than the difference of the other two sides; and the third side of any triangle is lesser than the sum of the two other sides

Then, we can write that

AB < 27 + 54

and

AB > 54 - 27

Putting the two inequalities together, we get

54 - 27 < AB < 27 + 54

27 < AB < 81

Hence, the expression that expresses all possible lengths of segment AB is 27 < AB < 81. The correct option is the second option 27 < AB < 81

Answer:

Step-by-step explanation:

Givens

Number of cookies = 16

Deduction =  7

Final Cost = 13.31

Equation

16c - 7 = 13.31

Solution

You are not asked for a solution but I'll put it here anyway.

16c - 7 = 13.32                      Add 7 to both sides

16c -7+7 = 13.32+ 7              Combine

16c = 20.32                          Divide by 16

16c/16 =  20.32/16

Multiply 1080 by 0.25 for the 25% which then should equal $810. 810 times 0.08 would equal 64.8. Add the 64.8 to the 810 and it should be $874.80. Hope it helps and is not wrong. :)
