Answer: n = 63
Step-by-step explanation:
1260/20 = n/1
63/1 = n/1
n = 63
Answer: (129.12 ft^2) / (24 ft^2/can) = 5.38 cans. Round this up to 6 cans. Please undrstand that this is only an example, since I do not know the actual dimenions of the wall
The angle is 75.52 degrees
If there is a vector with the form a i + b j, the cosine of the angle between the given vector and the positive direction of the x - axis is calculated as:
cos θ = 
So, given the vector i+
, the cosine of the angle between the vector and the x-axis is:
cos θ = 0.25
Therefore, the angle θ between the given vector and the positive direction of the x-axis is:
θ = cos-1(0.25) = 75.52

Answer: Random
Step-by-step explanation:
- In statistics , a random sampling technique is a simple sampling technique in which researcher choose 'n' individuals from N population , such that the chances for each individual to get selected are equal as
.
Here , the company wants to administer a satisfaction survey to its current customers.
So , Population → All current customers
Using their customer database, the company randomly selects 80 customers , it means each customer had the same chance to get selected.
Hence, the type of sampling is used : Random sampling
Hence, the correct answer is "Random" .
