Answer: 38
Step-by-step explanation:
3.8=19/5
u have to flip the reciprocal to divide by fraction so 1/10 will be just 10
Then u get 19/5 x 10
You can reduce the GCF so it would be 19 x 2
19 x 2 = 38
Or you can plug it into your calculator (3.8 x .1)
12 (don't take my answer because it's been awhile since I've fine a question like that but I'm pretty sure it's 12)
Answer: C.
Simple random sampling
Step-by-step explanation:
A simple random sample in statistics, is a subset of individuals chosen from a larger set. Each individual is chosen randomly and entirely by chance, such that each individual has the same probability for the entire larger set.
Answer:
1399 sq. feet
Step-by-step explanation:
Now, the data given is
height of front of apartment = 60 feet
Width of front of apartment = 25 feet
So total are of front of apartment is = Height x Width
= 60 x 25
= 1500 sq. yards
Now for door
Height = 7 feet
Width = 3 feet
So, total are of door
= Height x Width
= 7 x 3
= 21 sq. yards
Now for each window
Height = 4 feet
Width = 2 feet
So, total are of one window
= Height x Width
= 4 x 2
= 8 sq. yards
Now note that, for 10 windows area will be
= 8 x 10
= 80 sq. yards
Now understand that we have to find the area for bricks, but bricks will cover entire front except the door and windows. So, we have to subtract area of door and windows from total front area of apartment.
Area for bricks = Total front area - (area of door + area of 10 windows)
Area for bricks = 1500 - 21 - 80
Area for bricks = 1399 sq. yards
