Answer:
11) mean=2 12) median=2 13)range =4
Step-by-step explanation:
11) the set is
0,0,1,1,1,2,2,2,2,2,3,3,3,4,4
so add all these which will give you 30 and then divide that by how many numbers are there in the set which there are 15, so 30 divided 15 =2
12) arrange numbers from smallest to largest and the number exactly in the middle is the median
13)biggest number-smallest number

Answer:
(d) Infinitely Many Solutions
Step-by-step explanation:
Each point of intersection between the lines is a solution. When the lines lie on top of each other, there are infinitely many points of intersection, hence ...
Infinitely Many Solutions
Assume that the length of the rectangle is "l" and that the width is "w".
We are given that:
(1) The length is one more than twice the base. This means that:
l = 2w + 1 .......> equation I
(2) The perimeter is 92 cm. This means that:
92 = 2(l+w) ...........> equation II
Substitute with equation I in equation II to get the width as follows:
92 = 2(l+w)
92 = 2(2w+1+w)
92/2 = 3w + 1
46 = 3w + 1
3w = 46-1 = 45
w = 45/3
w = 15
Substitute with w in equation I to get the length as follows:
l = 2w + 1
l = 2(15) + 1
l = 30 + 1 = 31
Based on the above calculations:
length of base = 31 cm
width of base = 15 cm
