For which data sets is the median a better measure of center than the mean?
vaieri [72.5K]
<span>The median is a better measure of center when there is an outlier which will make the mean not be a good estimate of the center. Option B has $1075 as an outlier (i.e. it is far away from the other data sets). Hence, the median will be a better estimate of the center. Similarly, 94 is an outlier in option C and hence, the median is a better estimate. Options A and D has no outliers, making the mean a good estimate of the centre.</span>

Step-by-step explanation:

\frac{4}{5}  \div  \bigg[  {\bigg( \frac{4}{5} \bigg)}^{7} .{\bigg( \frac{4}{5} \bigg)}^{0}\bigg]  \\  \\  =  \frac{4}{5}  \div  \bigg[  {\bigg( \frac{4}{5} \bigg)}^{7} .1\bigg] \\  \\  =  \frac{4}{5}  \div    {\bigg( \frac{4}{5} \bigg)}^{7}\\  \\  =  \frac{4}{5}  \times    {\bigg( \frac{5}{4}\bigg)}^{7} \\  \\  = {\bigg( \frac{5}{4}\bigg)}^{6}

Explain how to solve 4^x+3 = 7 using the change of base formula log base b of y equals log y over log b. Include the solution fo
Masja [62]

The value of x is 1

Explanation:

The equation is 4^x+3=7

Subtracting both sides by 3, we get,

4^x=4

Taking log on both sides, we get,

\log 4^{x}=\log 4

Rewriting the equation by 4^{x}=u

Thus, we have,

\log u=\log 4

Applying log rule, if \log f(x)=\log g(x), then f(x)=g(x)

Thus, u=4

Substituting u=4 in 4^{x}=u, we get,

4^x=4

Also, since, a^{f(x)}=a^{g(x)}, then f(x)=g(x)

Thus, x=1

Hence, the value of x is 1
