Step-by-step explanation:
from the available data in this question,
1.
this population is applicable to those teenagers in the study who are aged 13 to 17 years and who own a smartphone
2.
from the question, this population is applicable to the the teenagers in the study within the age of 13 to 17 years who do not own a smartphone.
3. pew research conducted a sample survey and not a census to obtain their results. it would be illogical and not practical to conduct a census. A sample survey is better for this since it would cost less, save more time and also the members of the survey can easily be picked from the american teenage population.. a census would require data for the full population compared to sample survey which would only require a subgroup of the teenage population.
Answer:
B) (-∞,1)
Step-by-step explanation:
g(x)=-2f(x)+1
g(x)=-2(10^x)+1
Therefore, x can be any real number, but y can be any real number that's less than 1. This means B is correct.
m = 2p + 3
I'm going to say that is correct because you're trying to find m, which is Linda's score. And her score is 2 times + 3 more than Lisa's.
Hope this helps!!(:
(3, -7) and (-1, 1)
To find slope of a line using 2 points
we use formula
(3, -7) is (x1,y1) and (-1, 1) is (x2,y2)
Here x1= 3 and y1= -7
x2=-1 and y2=1
=-2
slope of a line using 2 points (3, -7) and (-1, 1) is -2
