Answer: A) The survey represents quantitative data.
Step-by-step explanation:
From the given data, we can conclude that the survey represents quantitative data (which can be calculated). Thus A) is the correct option.
Let's check other options.
B) Number of girls do not own a pet=7
total girls =20
Thus percentage of girls do not own pet=
Number of boys do not own a pet=8
total boys =15
Thus percentage of boys do not own pet=
Clearly the percentage of boys own pet is greater than percentage of girls do not own pet.
Thus B is wrong
C) The total number of girls who own 2 or more pets is 2
= girls own 2 pets+girls own more than 2 pets
=5+2=7≠2
Thus, C is wrong
D) Girls do not own a pet = 7
Girls do own a pet =Total girls -girls do not own a pet
=20-7=13
Thus, there are more girls do own a pet than do not own a pet.
Thus, D is wrong.
Answer:
Not possible.
Step-by-step explanation:
Addition of Matrix A and Matrix B is possible only if the order of matrix A is same as the order of matrix B.
Order of a matrix with rows and
columns is
.
Here, matrix A is
Matrix B is .
Multiplying a matrix by a constant doesn't change its order.
So, order of matrix A is as it has 3 rows and 2 columns.
The order of matrix 3B is as it has 2 rows and 3 columns.
Therefore, addition is not possible as the order is different.
