Answer:

  6. 15/22

  7. 1/12

  9. 1/16

  10. 0

Step-by-step explanation:

6. 10 of the 12 tiles are "not P", so the probability of a "not P" on the first draw is 10/12 = 5/6. After drawing a "not P" on the first draw, 9 of the remaining tiles are "not P". The probability of drawing one of those is 9/11. So, the joint probability of drawing two "not P" tiles is ...

  (5/6)(9/11) = (5·9)/(6·11) = 15/22

__

7. The probability of drawing a tile worth 3 points is 3/12 = 1/4. The probability of drawing a tile worth 1 point is 4/12 = 1/3. So, the joint probability of drawing a 3-point tile, then a 1-point tile is ...

  (1/4)(1/3) = 1/12

__

9. There are 3 of the 12 tiles worth more than 4 points. The probability of drawing one of them  is 3/12 = 1/4. The probability of doing it again is also 1/4, so the probability of doing it twice is ...

  (1/4)(1/4) = 1/16

__

10. The probability of drawing a Z is 1/12. Having drawn a Z, the probability of drawing a 10-point tile is 0/11. The joint probability of drawing a Z twice is ...

  (1/12)(0/11) = 0

What is geometrical series?

A geometric series is the sum of an unlimited number of terms with a fixed ratio between them.

Option A: You receive 1¢ on the first day, 3¢ on the second day, 9¢ on the third day, 27¢ on the fourth day, and so on, tripling each day.

The sum of money till the 10th day will be

Answers

Given the inequality expression 4 + x > 6, we need to solve for x and graph the equivalent graph of the function;

Given

4 + x > 6

Subtract 4 from both sides of the inequality

4 + x - 4 > 6 - 4x > 6 - 4x > 2

Next is to graph the solution x > 2 on the number line.

Since the inequality sign is greater than sign, the line arrow will point towards the right of the number line and the circle will be an open circle.

the answer to the first one is $7.60 because when you add $0.40 with $0.90, you get $1.30. because you have to add this to the money in the piggy bank, you would get $7.60; $6.30 + $1.30

Answer:

1.) 7.60

2.) 3.70

3.) 7.20

4.) 9.20

Step-by-step explanation:

6.30 + 0.40 + 0.90 = 7.60

Barrys has $7.60 total

3.20 + 1.60 = 4.80

8.50 - 4.80 = 3.70

Henrys change is $3.70

1.20 + (1.20 × 5)

1.20 + 6 = 7.20

The bouncy ball and pen cost $7.20 together

Monday: $2.30

2.30 × 3 = 6.9

Tuesday: $6.90

6.90 + 2.30 = 9.20
