The answer is not any of the letters. I got x=15/2 or x=7.5. You may have made an error in your question.
Answer:
B.
Step-by-step explanation:
First you need to figure out how many numbers there are, so with this you can simply count 10. Then use the formula to plug in the numbers: 10(22-77)/2 to get the answer.
Answer:
is correct
Step-by-step explanation:
∠BDC and ∠AED are right angles, is a piece of additional information is appropriate to prove △ CEA ~ △ CDB
Triangle AEC is shown. Line segment B, D is drawn near point C to form triangle BDC.
<h3> What are Similar triangles?</h3>
Similar triangles, are those triangles which have similar properties,i.e. angles and proportionality of sides.
Image is attached below,
as shown in figure
∡ACE = ∡BCD ( common angle )
∡AED = ∡BDC ( since AE and BD are perpendicular to same line EC and make right angles as E and C)
∡EAC =- ∡DBC ( corresponding angles because AE and BD are parallel lines)
Thus, △CEA ~ △CDB , because of the two perpendiculars AE and BD.

Answer:
probability of getting four head consecutively is 0.2
Step-by-step explanation:
in an experiment coin is flipped 4 times.
given, coin landed heads up more than two times
outcomes of coin landed heads up more than two times =
SAMPLE SPACE : [ {HHHT}{HHTH}{HTHH}{THHH}{HHHH} ]
chance of getting 4 heads = 1 (HHHH)
Probability = 
hence the probability of getting four head consecutively is 0.2
