To find the mean in a set of data you need to add all the numbers and divide by the number of digits.
–6 + 3 + –2 + 6 + 7 + –3 + –5+ 8 = 8
8 divided by 8 because there are 8 numbers which equals 1
So your final answer is <u>1 </u>
Answer:
570cm squared
Step-by-step explanation:
Multiply 38 by 15.
I believe x is 0 because if we assume y and x are 0 then 0=0 and 0= 5 x 0
<span>The answer is D. $12.26. The cost is $0.14 per 1 mile. The question is how much will be per 87.6 miles. Make a proportion: $0.14 per 1 mile. x per 87.6 miles. $0.14 : 1 mile = x : 87.6 miles. Cross the products: x * 1 mile = $0.14 * 87.6 miles. x * 1 mile = $12.26 per mile. x = $12.26 per mile / 1 mile. x = $12.26.</span>
Let x be the months and y be the cost.
Rate of increase of commodity A = 6/3 = $2 per month
Equation:
y = 2x + 4500
Rate of increase of commodity B = 2/4 = $0.5 per month
Equation:
y = 0.5x + 5400
Equating the costs,
2x + 4500 = 0.5x + 5400
1.5x = 900
x = 600 months
x = 600 / 12 = 50 years
