Iuliana has 22 quarters and dollar coins worth a total of $10.75.

which equation can be used to find d, the number of dollar coins giuliana has?

d – 22 + 0.25d = 10.75

0.25d + 22 – d = 10.75

0.25(22 – d) + d = 10.75

d + 0.25(d – 22) = 10.75

Which ordered pair (c,d) is a solution to the given system of linear equations- c+2d=13 -9c-4d=-15

The fraction of defective integrated circuits produced in a photolithography process is being studied. a random sample of 300 circuits is tested, revealing 17 defectives. (a) calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool. round the answers to 4 decimal places. less-than-or-equal-to p less-than-or-equal-to (b) calculate a 95% upper confidence bound on the fraction of defective circuits. round the answer to 4 decimal places. p less-than-or-equal-to
