Answer:
• Random sampling [ Probability and statistics method ]
Step-by-step explanation:
• This method is easier and saves time.
By probability, a person whose height is to be recorded will be chosen randomly. This will be done on approximately 40% members.
By statistical step, we'll feed results into distribution table. Then we'll find the mean height.
• f of n is product of frequency and respective height bracket
• n is the number of samples.

Here we can first find the area of yard and then subtract the area of vegetable garden to get the required area.
The formula to find area is given by:
Now we find area of yard:
length is 25 ft and width is 15 ft.
Area of yard = 375 ft²
Area of vegetable garden:
length = 8ft and width =8ft
So the vegetable garden is a square.
Area = 8*8
Area of vegetable garden =64 ft²
Area of backyard to be laid with grass = Area of yard-Area of vegetable garden
Area required = 375 -64 = 311 ft²
Answer : The area of backyard in which grass is to be laid is 311 square feet.
Answer:
25.5 mi
Step-by-step explanation:
12 22.5 X
Let X be the shortest distance we are trying to find.
a units 2 b units 2 c units 2
12 units 2 + (22.5)=c units 2
144+506.25=c units 2
650.25=c units 2
=c units 2

Answer:
The equation of the line is:
Step-by-step explanation:
We know that the slope-intercept of line equation is
Where m is the slope and b is the y-intercept
Given the two points on a line
- (0, 3)
- (-2, -5)
Finding the slope between (0, 3) and (-2, -5)
We know that the y-intercept can be computed by setting x=0 and determining the corresponding y-value.
From the graph, it is clear:
at x = 0, y = 3
Thus, y-intercept = b = 3
Substituting m = 4 and b = 3 in the slope-intercept form of line equation
Therefore, the equation of the line is:
