Answer 1

Answer:

Step-by-step explanation:

14) P(two heads ) = 105 / 500

P ( one head) = 275 / 500

P ( No head) = 120 / 500

15) x + x+2/ 2 = 63

x + x+2 = 63 * 2

x + x+2 = 126

2x+2 = 126

2x = 126 - 2

2x = 124

x = 62

x= 62 + 2 = 64

OR

Mode = 12

Mean = 12+17+9+13+16+ 9+12+13+12+17 / 10

= 130/10

= 13
