Step-by-step explanation:

35.25 / 1.50 = 23.5 donuts - you can not purchase a half of a donut  so you can buy 1 coffee and 23 donuts for $36.25

Find the unknown number 5/12+()=1/2
xenn [34]

Hello from MrBillDoesMath!

Answer:    1/12


Discussion:

We solve  5/12 + x = 1/2 for x. Begin by subtracting 5/12 from each side

5/12 - 5/12 + x  =    1/2 - 5/12

0                  +x =    6/12 - 5/12      (as 1/2 = 6/12)

So x = 1/12

RSB [31]

Hence, the standard deviation for these data is 7.1 sessions

In statistics, the standard deviation is a measure of the volatility or variance of a set of values. [1] A low standard deviation indicates that the values ​​tend to be close to the mean of the set (also known as the mean), and a high standard deviation indicates that the values ​​are more widely distributed. indicate.

Standard deviation can be abbreviated as SD, and in mathematical texts and equations, it is most commonly represented by the Greek lower σ (sigma) for population standard deviation or the Latin letter s for sample standard deviation. It is a target.

The standard deviation of a random variable, sample, population, dataset, or probability distribution is the square root of its variance. It's algebraically simple, but it's actually less robust than mean absolute deviation. A useful property of standard deviation is that, unlike variance, it is expressed in the same units as the data.

Expression

\ sigma = {\ sqrt {\ frac {\ sum (x_ {i}-{\ mu}) ^ {2}} {N}}}

\ sigma = Population standard deviation

N = size mother Population

x_i = Arbitrary value from population

\ mu = Population mean
