Answer:

The answer to your question is the big dog weighs 120 pounds

Step-by-step explanation:

Data

big dog = b    

medium dog = m

small dog = s

Equations

       b = 5s

       m = 12 + s

       s = 2/3 m

Process

1.- Substitute m in the last equation

       s = 2/3(12 + s)

       s = 24/3 + 2/3s

       s - 2/3s = 8

       1/3 s = 8

             s = 8(3)

             s = 24 pounds

2.- Substitute s in the first equation

        b = 5(24)

        b = 120 pounds

For the data set {14, 10, 10, 23, 14, 10, 17}, which measures of center best describe the data?
Daniel [21]
Figure out the Median if there is an odd set of numbers (like above 7) then its the number in the middle. If there is an even set of numbers then the Median is the mean of the two center numbers. (10,10,10,<14 >,14,17,23)  MEDIAN: 14 

To find the Mean add all the numbers together 10+10+10+14+14+17+23 = 98 then we divide the amount of numbers to the sum of the Mean you just added 98÷7=Mean:14The Mode is figured out by writing the numbers out from least to greatest: 10,10,10,14,14,17,23 The Mode is the number that occurs most often Mode:10



There is more than one answer we know this because of the question :Choose All and both our Median and Mean are 14   (Answer: A and B)

Snowcat [4.5K]
X * 8/100 * 1 +  9/100 * (11,000 - x) = 980
0.08 x + 0.09 (11000 - x) = 980 Now solve for x which is the amount invested at 8%

0.08x + 990 - 0.09x = 980
- 0.01x = 980 - 990 = -10
x = -10 / -0.01
x = 1000

So he invest 1000 in 8% and 10000 at 9%
