Y - 3 = -1/4(x - 4)
y - 3 = -1/4x + 1
y = -1/4x + 1 + 3
y = -1/4x + 4
ok....the y int is (0,4)....the slope is -1/4...
x int can be found by subbing in 0 for y and solving for x
y = -1/4x + 4
0 = -1/4x + 4
1/4x = 4
x = 4 * 4
x = 16....so ur x int is (16,0)
so first plot ur points (0,4)....and since ur slope is -1/4, go down 1 space and to the right 4 spaces, then down 1, and to the right 4....keep doing this and u will cross the x axis at (16,0)
Answer:
4
Step-by-step explanation:
We can see that 9 households are represented in the data, 4 of them are zeros. This means 4 households in Cam's neighborhood have 0 children.
Each little square is 1 inch high and 1 inch wide, so
the area of each little square is 1 square inch.
The bug figure is made of 23 little squares, so the area
of the big figure is 23 square inches.
By using a sampling technique we ensure that we choose a sample of students that is representative of all 8:00 am classes.
There are varieties of sampling strategies: chance sampling includes random selection, permitting you to make sturdy statistical inferences approximately the complete organization. Non-opportunity sampling entails non-random selection primarily based on convenience or different standards, permitting you to without problems gather records.
Random sampling is part of the sampling technique wherein every sample has an same possibility of being chosen. A sample chosen randomly is meant to be an unbiased representation of the overall population.
explanation;
we conclude the
- 6 buildings in the college
- 4 lecture halls in each building
- 100 students in each lecture hall
Since the students' lecture hallsare on different building the samples are
Dividing the students into groups, the students will be grouped by the buildings of their lecture halls.
The number of students in each building is:
There are 100 students in each building
Then select at random an equal proportion of student from each building let 20 students in each building.
