median = 30.5
lower IQR = 27.5
upper IQR = 40.5
Range IQR = 40.5 - 27.5 = 13
answer is 13
The answer is 2 two(2x2)=4
The function and the first value stated for x are confusing.
Doing some research, I found that the problem is to evaluate the function
for x = - 1 and x 2.
The solution is:
1) For x = - 1
2) For x = 2
Step-by-step explanation:
Total money paid=$110+$5.5=115.5
Cost of each shirt=$8
Therefore,
No. of T shirt req.=115.5/8=14.4
So they req. 15 T-Shirts
Answer:
540 m
Step-by-step explanation:
The building of the Blue Museum of Barcelona is triangular and each side of the building is 180 m.
This means the building is shaped as an equilateral triangle.
We need to find the total distance traveled if we go round the building, that is, its perimeter.
The perimeter of an equilateral triangle is given as:
P = 3L
where L = length of the side of the building = 180 m
The total distance traveled if we go round the building will be:
P = 3 * 180 = 540 m
We would need to go 540 m to travel around the building completely.
