Answer:
D
Step-by-step explanation:
means the inverse. The inverse is the function reflected over the y=x line. This means the values have been reversed. (x,y)-->(y,x). We are looking for a point that has reversed values from the table.
The table has (1.-5) so the inverse is (-5,1) or D.

Step-by-step explanation:
for an AP
where
a
1
=
the first term
d
=
the common difference
then we have
a

)
,
(
a

2
d
)
,
...
,
a

we are given the third term

d
−

and the fifth term
26
=
a

subtract

d
⇒
d

sub into
(

10
=

×
8
⇒
a

so the nth term

Answer:
about 48.6%
Step-by-step explanation:
20 women's shoes are athletic.
35 women's shoes are formal.
52 women's shoes are casual.
The total number of women's shoes is 107. So the probability that a randomly selected one is casual is:
P = 52/107
P ≈ 48.6%
Unit cost to sales price is 1:4.....or 1/4
1 / 4 = 33.85 / s.....1 unit cost to 4 sales price = 33.85 unit cost = s sales price
cross multiply
(1)(s) = (4)(33.85)
s = 135.40 <=== selling price
