For this case what you should do is observe the classic graph of supply and demand.
In this graph, we are going to visualize only the demand curve.
Two facts are met for the claim:
1) If the price is high, the quantity demanded decreases.
2) If the price is low, the quantity demanded increases.
Answer:
The lower prices imply an increase in the quantity demanded.
The theorical probability is 1/4, because there are 4 possible outcome, and they are equally likely to be picked (the sectors have the same area)
The experimental probability is 3/20, becuase the red sector was picked 3 times in 20 trials.
Answer:
23 students
Step-by-step explanation:
6 boys: 11 girls
x boys: 15 girls Add in the new equation
15/11 is about 1.36 Find the scale factor used
6 x 1.36 is about 8.18 Multiply the scale factor by the known amount of boys
Since we are adding students, there can't be part of a student.
6 boys: 11 girls
8 boys: 15 girls
There is a total of 23 students in the school play.
-5 and 21
21 - 5 = 16
21 × (-5) = -105
