Which integer is closest to 0 on the number line?
IrinaVladis [17]

An integer is close to zero if it is "small".

By small, we mean that it is small in absolute value. In fact, for any given distance d, there are two integers that are d units away from zero: d and -d.

So, for example, -6 is close to zero than 8, because -6 is six units away from zero, while 8 is eight units away from zero.

So, the answer is B, -8, because it is 8 units away from zero. The other options A, C and D are, respectively, 12, 10 and 14 units away from zero.

2. What is the external probability of rolling a 4
Nataly_w [17]

Answer:

2. 1- Experimental probability of rolling a 4 = 40%

3. 2- Theoretical probability is 3%  greater than experimental probability.

Step-by-step explanation:

Experimental probability of rolling a 4 = 100 × \frac{8}{20}

                                                                  = 100 × 0.4

                                                                  = 40%

Experimental probability of getting at least one tail  = \frac{72}{100}

                                                                                    = 0.72

Theoretical probability of getting at least one tail  = \frac{3}{4}

                                                                                  = 0.75

Theoretical probability is 3%  greater than experimental probability.
