A data set has a mean 25 and standard deviation 5 find the z score of 39

Step-by-step explanation:

The z-score helps describe a value's relationship to the mean. It tells us how many standard deviations a value is from the mean. The formula is:

where x is the value, x-bar is the mean, and s is the standard deviation.

We know the data set has a mean of 25 and a standard deviation of 5. The value we are finding the z score for is 39.

Substitute the values into the formula.

Solve the numerator.

The z-score for 39 is 2.8. This means a value of 39 is 2.8 standard deviations greater than the mean.

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

step-by-step explanation:

consider an orange peel: if you want to try and lay it flat, you have to stretch it, we know exactly how things are being stretched or squashed at any given point. we have many different map projections because each has different patterns of some projections can even preserve certain features of the earth without
