S is the number of times you pick heads. The probability is 1/2 of picking heads and 1/2 picking tales. S - Bin (100, 1/2), and E(s)=100·1/2=50
Var(s)=100·1/2·1/2=25
Standard deviation of s=5

Find the values of the variables in the parallelogram. The diagram is not to scale.
Anna [14]

Answer:

  • Option C

Step-by-step explanation:

  • x = 36° as alternate interior angles are congruent
  • z = 110° as opposite angles of parallelogram are congruent
  • x + y + 110° = 180° as adjacent angles of parallelogram are supplementary
  • y = 180° - 110° - 36° =  34°

Correct choice is C

Which of the following values has 4 significant figures?
Vlad1618 [11]

Answer:

А. 13.07

Step-by-step explanation:

Significant figures are the number of digit from a number that have meanings. The higher the significant figures of a number, the higher its accuracy will be.  The only non-zero number will be count as significant figures unless the zero is between two non-zero numbers like 13.07, the zero placed between 3 and 7. Some number also doesn't count as significant figures like the leading zero.

All other option just shows 3 significant numbers, so the answer is 13.07
