1. Mean is the number you get when you add all these numbers and then divide by the number of numbers. So, (31 + 28 + 30 + 31 + 30) / 5 = 150 / 5 = 30
2. The median is the middle number in the list of numbers, so, the answer is 30 as well.
3. Mode is the number that appears most often, so here it is 30 and 31 because they both appear 2 times.
4. Range is the difference between the largest and smallest number, so 31 - 28 = 3.
x = 1 because -7(3x + 4) must be -49 so 3x + 4 must me 7 so x = 1
Answer:
810
Step-by-step explanation:
Answer:
rectangular tables
Step-by-step explanation:
x: how many tables
a) 49x/49=800/49
x=16.3
so roughly 16 tables
b) 64x/64=800/64
x= 12.5
so roughly 12(you round to nearest even number when it is .5)
c) Now we will calcuate how many people will fit using the number of fitting capacity
=16 (8)
128
=12(12)
=144
Therefore, the rect tables will fit more people
