X = 16
x = - 16

You could do it this way
x^2 - 256 = 0
(x - 16)(x + 16) = 0
x - 16 = 0
x = 16

x + 16 = 0
x  = - 16

Flip a coin 10 times and record the observed number of heads and tails. For example, with 10 flips one might get 6 heads and 4 t
zepelin [54]

Answer:

The greater the sample size the better is the estimation. A large sample leads to a more accurate result.

Step-by-step explanation:

Consider the table representing the number of heads and tails for all the number of tosses:

Number of tosses    n (HEADS)        n (TAILS)            Ratio

            10                         3                      7                    3 : 7

           30                         14                    16                   7 : 8

          100                        60                   40                  3 : 2

Compute probability of heads for the tosses as follows:

  • n = 10 tosses

        P(\text{HEADS})=\frac{3}{10}=0.30

The probability of heads in case of 10 tosses of a coin is -0.20 away from 50/50.

  • n = 30 tosses

        P(\text{HEADS})=\frac{14}{30}=0.467

The probability of heads in case of 30 tosses of a coin is -0.033 away from 50/50.

  • n = 100 tosses

        P(\text{HEADS})=\frac{60}{100}=0.60

The probability of heads in case of 100 tosses of a coin is 0.10 away from 50/50.

As it can be seen from the above explanation, that as the sample size is increasing the distance between the expected and observed proportion is decreasing.

This happens because, the greater the sample size the better is the estimation. A large sample leads to a more accurate result.

Two times the greater of two consecutive integers is 9 less than three times the lesser integer. What are the integers?
blondinia [14]
Let the two integers be x and x + 1, then
2(x + 1) + 9 = 3x
2x + 2 + 9 = 3x
3x - 2x = 11
x = 11

Therefore, the integers are 11 and 12.
