Answer:
we say the number of samples is 4
Step-by-step explanation:
Given data
sample = 100
total sample conduct = 4 time
to find out
What is the number of samples
solution
we know that sample size for each month is 100
4 time sample taken January, march, June and September.
so that no of people sample is = 4 × 100 = 400
so that for number is sample is 400 /100
so we say the number of samples is 4
Answer:
7m^2 - 11m - 2
Step-by-step explanation:
Subtract (-3m^2 + 10m + 4) from 4m^2 - m + 2:
4m^2 - m + 2
- (-3m^2 + 10m + 4) Now distribute the negative sign:
4m^2 - m + 2
+ 3m^2 - 10m - 4
--------------------------
7m^2 - 11m - 2 is the final answer.
Since x represents the length (in meters), the width, which is 7 meters greater, is x +7. The product of these dimensions is the area (in square meters):
x(x +7) = 170
In standard form, the quadratic is ...
x² +7x -170 = 0
