To find the answer to this you have to first look at what the question is asking. It wants to know how adding the horses weight affects the mean & median. To get this answer you would first find the mean and median of the weights of the animals WITHOUT the horse. The mean WITHOUT the horse is the average. Add all your weights up then divide by 8 since you have 8 animals. The weights of all animals without the horse equal to 285. We then divide 285 by 8, which gives us 35.625. To find the median, we just have to find the middle. The median is 17. Now to see how the original mean and median is affected we do the same procedure again, but this time adding the horses weight in. So the original weights of all animals 285 plus the horses weight 900, brings us to a total of 1,185. We then divide that by 9, since we are including the horse into the average. 1,185/9 = 131.66. The mean DRASTICALLY increases. Now we do the same procedure for median except we add the horse in. The mean is 27. Again we notice an increase in both median and mean. Therefore your answer is B. They both increase, but the mean increased more than the median. Hope this helps :)

The answer is B because the mean is 131.6 and the median is 36, and obviously 131.6 is the greater value. Hope this helps! If I am wrong, someone in the comments please correct me

Divide and answer in simplest form: 1/3 divided by 5
disa [49]

Answer:

1/15

Step-by-step explanation:

1. You can divide 1/3 by 5 by changing the division symbol to its reciprocal, multiplication, and also divide by the reciprocal of the number after the symbol, 5. The reciprocal of 5 is 1/5.

2. Now you can do 1/3 multiplied by 1/5. Multiply the numerators by the denominators. The numerators are 1 and 1, so you multiply 1 by 1 which equals 1. Now you multiply the denominators, 3 and 5, which is equal to 15. If the numerator is now 1, and the denominator is 15, the new fraction is 1/15, getting you to your answer

5 ( n - 7 ) = 2 ( n + 14 )
wariber [46]

Answer:

n=21

Step-by-step explanation:

We must find n.

Remember PEMDAS. First we must do the Parentheses. Lets do distributive property by multiplying a number that is immediately outside the parentheses with each number inside the parentheses. Lets do this one side at a time.

First lets do 5(n - 7). We get 5n - 35

Now 2(n + 14) is 2n + 28

Okay...... now we have 5n-35=2n+28

Now lets do OPPOSITES!!!! We must do the opposite of each thing to both sides.

The opposite of -35 is positive 35. Lets add 35 to both sides. We get:

5n=2n+63

Now lets do the opposite of 2n which is -2n

3n=63

this is looking quite nice isnt it..........

The opposite of 3 times n is 3 DIVIDED BY n. So lets divide both sides by 3

n=21

amazing.......
