Answer:
This statement if FALSE
Step-by-step explanation:
This question deals with the concept of competing products and how the price of a product effects its demand
There are two competing bulbs
a) Compact fluorescent light bulbs
b) Incandescent light bulbs
The first statement exclaims that the price of the product (a) decreases and this causes the demand of product (a) to increase, this would decrease the demand of product (b) as they are competitors.
To retaliate against the loss of sales of product (b) the price of product (b) is decreased, this should increase the demand of product (b) but the statement says the the demand of product (b) further decreases.
Since we know from the statement that sales were primarily driven by the price of the products, the demand of product (b) should have increased. Hence this statement is false
In this question, each star equal to 4 students. If the people on 85 and 90 take the test again that means their number should be 14+4 people= 18 people.
If they all get 95, then it means we need to add 18 people to the 95 graph. The number of stars would be: 18 people / (4people/stars)= 4.5 stars
If you add the stars graph it will be easier. It should be clear that 85 will have 1 stars and 90 have 3.5 stars. Adding them up will be 1 stars + 3.5 stars= 4.5 stars
