7. Lauren has a purse full of dimes and quarters. She has 25 less dimes than
quarters. If she has a total of $10.45,
which system of equations would she
write to find the number of dimes, d
and quarters, ?
d + 9 = 25
.10d +.259 = 10.45
A. REI.6-1 - So
by Graphing
d + 9 = 25
.25d +.107 = 10.45
Show Step-
9 -d = 25
.10d +.259 = 10.45
o
d- 9 = 25
.100 + 259 = 10.45
O

An optical inspection system is used to distinguish among different part types. the probability of a correct classification of any part is 0.92. suppose that three parts are inspected and that the classifications are independent. let the random variable x denote the number of parts that are correctly classified. determine the probability mass function of x. round your answers to four decimal places (e.g. 98.7654). x f(x) 0 1 2 3

What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )
