I think the answer is 4, the earthquake is a 4 in the scale.
The answer is x=-7
8x-7x-2=-9
8x-7x=-9+2
-7
8^14 is the answer.
This is because since they both have the same base, the exponents could be added together if the numbers are multiplied together
Answer:
27(less than symbol) 5x+7
Step-by-step explanation:
5 times a number is 5x
increase means add
Calculate the mean, median, and mode of the following set of data. Round to the nearest tenth. 10, 1, 10, 15, 1, 7, 10, 10, 1, 6
klemol [59]
First order the data:
1, 1, 1, 6, 7, 10, 10, 10, 10, 13, 15
the mean is all the numbers added together divided by how many there are, 1 + 1 + 1 + 6 + 7 + 10 + 10 + 10 + 10 + 13 + 15 = 84 84/11 = 7.636364 ≈ 7.6
the median is the number in the middle of the list, count numbers from each end, until you either have one or two left, if one left then its that one, if two left then its half way between the two
the median for your set is 10
The mode is the most common number, in your set 10
