Answer:
The probability is 40%
Step-by-step explanation:
a) There are ten pieces of paper with ten numbers
Probability of selecting four pieces of paper = 4/10 or 40%
Probability that the four numbers selected will have a sum greater than 82 = 82/205 = 40%
Therefore, the probability of selecting four numbers that have a sum greater than 82 out of ten numbers totalling 205 is 40%.
b) Probability is the ratio of the number of outcomes favourable for the event to the total number of possible outcomes. In other words, it is a measure of the likelihood of an event (or measure of chance).
Answer:
3
Step-by-step explanation:
21 can be divided by 3 also 36
Answer:
see explanation
Step-by-step explanation:
∠CBA = ∠BAG = 28° ( Alternate angles )
∠EAD = 90° - ∠BAG = 90° - 28° = 62° ( ∠EAG is right )
∠EDB is an external angle of ΔADE
• The external angle is equal to the sum of the 2 opposite interior angles
∠EDB = x + 4x = 5x
5x = 3x + 62 ( subtract 2x from both sides )
2x = 62 ( divide both sides by 2 )
x = 31, hence
3x = 3 × 31 = 93° and 4x = 4 × 31 = 124°
9 because the symbols around -12 and -3 so they would just become positive number 12 and 3. Subtract them and you get 9 :)
Approximately 61.
if you divide 420 by 6.82 you get 61.58 :)
