Answer:
C
Step-by-step explanation:
Given that (x + 8) is a factor of f(x), then x = - 8 is a root and thus
f(- 8) = 0
Answer:
The scale factor is 2/3.
Step-by-step explanation:
Given data,
The given image is (6,9)
The image after dilation is (4,6)
The scale factor is calculated by dividing the resultant image by the initial image.
For example, if the initial dimensions are (x1, y1) and the final dimensions are (x2,y2). The scale factor is calculated using x2/x1 = y2/y1 = Scale Factor
In our scenario,
x1 = 6
x2 = 4
y1 = 9
y2 = 6
Scale Factor = x2/x1
=> 4/6
=> 2/3
Similarly for y axis,
Scale Factor = y2/y1
=> 6/9
=> 2/3
Therefore, the scale factor is 2/3.
Answer: Option 'A' is correct.
Step-by-step explanation:
Since we have given that
the sample is chosen by asking people on the street.
Since every member chosen from the sample has an equal chance.
so, it is considered as simple random.
Systematic random is the method in which every n th member is selected or chosen.
Stratified random is the method of sampling in which population is divided into groups and the sample is making by choosing every member from each group
Cluster is the method of sampling in which the population is divided into groups and the sample is making by choosing every member from some of the group instead of every group.
But here, we have chosen by asking people on the street.
So, every member has equal chances.
So, it is sample random.
Hence, Option 'A' is correct.
