The value of young's modulus (gpa) was determined for cast plates consisting of certain intermetallic substrates, resulting in the following sample observations.
115.8 116.5 116.1 115.5 114.8
(a) calculate x and the deviations from the mean.
(b) use the deviations calculated in part (a) to obtain the sample variance and the sample standard deviation. (enter your answers to three decimal places.)
c) calculate s2 by using the computational formula for the numerator sxx. (enter your answer to three decimal places.)

step-by-step explanation:

so first find out how much each is worth.

quarter= 25 cents

dime= 10 cents

pennies= 1 cent

then multiply each by how much each is worth.

200                     150                   300

x                         x                     x   1

  25                       10              

                                  300

1000                     1500

+                          

4000                                      

5000                                  

then count 2 from the back and add a period.

$50.00

$15.00

$3.00

and then add them

  $50.00

+

  $15.00

+

    $3.00

$68.00

so sunghee has $68.00
