Step-by-step explanation: The base of the power in the original equation becomes the base of the log. So we have
.
Next, the exponent in the original equation goes on the other side of the equation and finally, the result in the
original equation goes inside the log.
So we have
which is 7³ = 343 written in logarithmic form.
Given that normally distributed data set has a mean of 55 and 99.7% of data fall between 47.5 and 62.5.
Let s be the standard deviation of data set.
Since 99.7% data fall within 3 standard deviations of mean, z-value for 47.5 and 62.5 has an absolute value of 3.
That is |z|=3
But z= 
Let us plugin x=47.5 and mean =55 and equate it to 3.
That is 

Since x is always positive ( being standard deviation), 
Hence 

We will get same value with 62.5 as well.
Hence standard deviation of data set is 2.5.
Oh okay. LOL have a great day whoever is reading this?
1 whole is the awnser because it would be 10\10 and if you simplify you get l whole
