What is 2 3/7 divided 5 1/5

Mathematics
1 answer:
DaniilM [7]3 years ago
3 0

In order to find the answer to this question you must change the mixed number into improper fractions (you do that by multiplying the denominator to the whole number then add the numerator and keep the denominator the same) then repeat the same rules you would do when dividing normal fractions. (use KCF) Then you solve.

2\frac{3}{7} \div 5\frac{1}{5}

2\frac{3}{7} = \frac{17}{7}

5\frac{1}{5} = \frac{26}{5}

\frac{17}{7} \div\frac{26}{5} =

\frac{17}{7} \times\frac{5}{26}

17 \times 5 =85

7 \times 26 = 182

= \frac{85}{182}

Therefore your answer is "85/182."

Hope this helps.

What is the center of the equation (x+12)^2 + (y-9)^2= 35
Reil [10]

Answer:

(-12,9)

Step-by-step explanation:

The equation of a circle is given by the equation (x-h)^2 + (y-k)^2 = r^2, where (h,k) is the center point on the graph.

Therefore, in the equation (x+12)^2 + (y-9)^2 = 35, the center point on the graph would be (-12,9).

1. Consider the data set 1,2,3,4,5,6,7,8,9.
ivanzaharov [21]

Answer:  a) Mean = 5, Median = 5

b) Mean = 15, Median = 5

c) Due to presence of outlier i.e. 99.

Step-by-step explanation:

Since we have given that

1,2,3,4,5,6,7,8,9

Here, n = 9 which is odd

So, Mean would be

\dfrac{1+2+3+4+5+6+7+8+9}{9}=\dfrac{45}{9}=5

Median = (\dfrac{n+1}{2})^{th}=\dfrac{9+1}{2}=5^{th}=5

If 9 is replaced by 99,

1,2,3,4,5,6,7,8,99

So, mean would be

\dfrac{1+2+3+4+5+6+7+8+99}{9}=\dfrac{135}{9}=15

Median would be same as before i.e. 5

The mean is neither central nor typical for the data due to outlier i.e. 99

Hence, a) Mean = 5, Median = 5

b) Mean = 15, Median = 5

c) Due to presence of outlier i.e. 99.
