If the probability of flipping heads is 0.70, the probability of flipping tails is 0.30. 

To find probability, you multiply the probability of each factor together:

P = 0.7  * 0.3 

P = 0.21 <em>or</em>
<em> </em>21%

Find the value of x such that the data set 31.7, 42.8, 26.4, and x has a mean of 35.
Travka [436]

Answer:

x = 39.1

Step-by-step explanation:

To find the mean, add up all the data points and then divide by the number of data points

(31.7+ 42.8+ 26.4+ x)/4 = 35

Multiply each side by 4

(31.7+ 42.8+ 26.4+ x)/4*4 = 35*4

(31.7+ 42.8+ 26.4+ x) = 140

Combine like terms

100.9+x = 140

Subtract 100.9 from each side

x = 140-100.9

x = 39.1
