Ted tossed a coin several times and recorded the number of heads and tails in the following table: Coin Experiment Side of Coin Number of Tosses Heads 18 Tails 22 What is the experimental probability of getting heads? 0.18 0.22 0.35 0.45

answer:

Correct answer is "D"0.45

Step-by-step explanation:

The results of the experiment are given as follows:

Coin Experiment Side of Coin Number of Tosses

                             Heads                           18

                              Tails                             22

This means that total 40 experiments were performed.

( Since 18+22=40)

Also, the number of times head turn up=18

Hence, the experimental probability of getting heads is:

Ratio of number of times head turn up to the total number of experiments performed.

Hence,

  Hence, the experimental probability of getting head is:

                                        0.45

*Hope this help

Have a nice day*

answer:

18 + 22 = 40 tries. 18 of those are heads so 18÷40=0.45

Step-by-step explanation:

answer: standard form is ax^2 + bx + c = 0

step-by-step explanation:

standard form is ax^2 + bx + c = 0

(2x + 1)(x - 2) = 0

distribute to get into standard form

2x^2 - 4x + x - 2 = 0

2x^2 - 3x - 2 = 0

a = 2, b= -3, c = -2

a is your answer

b). 4320 have a nice day
