Answer:
There will be 15 ways.
Step-by-step explanation:
5 exterior designs are offered to potential home buyers.
The builder has standardized 3 interior plans that can be incorporated in any of the 5 exteriors.
So, the number of different ways in which the exterior and interior plans be offered to potential home buyers is given by:
Therefore, the answer is 15 ways.
Given inequality:
To find:
Which values are solutions to the inequality.
Solution:
Substitute the values in the x place.
Option A: 48
6.9 ≤ 7
Therefore 48 is one solution of the inequality.
It is true.
Option B: -5
We cannot compare a complex number and a real number.
Therefore -5 is not a solution of the inequality.
it is not true.
Option C: 50
7.07 > 7
Therefore 50 is not a solution of the inequality.
It is not true.
Option D: 49
7 ≤ 7
Therefore 49 is one solution of the inequality.
It is true.
Option E: 44
6.6 ≤ 7
Therefore 44 is one solution of the inequality.
It is true.
Option F: 2401
49 > 7
Therefore 2401 is not a solution of the inequality.
It is not true.
Therefore 48, 49 and 44 are solutions to the inequality.
