<span>t - (-2) = 6
t + 2 = 6
subtract 2 to both sides
t + 2 - 2 = 6 -2
simplify
t = 4</span>
Answer:
We can expect $1.7 off
Step-by-step explanation:
We are given 10 fortune cookies out of which
$1 off = 7 cookies
$2 off = 2 cookies
$6 off = 1 cookie
Probability
A = drawing $1 off cookies P(A) = 7/10
B= drawing $2 off cookies P(B) = 2/10
C= drawing $6 off cookie P(B) = 1/10
Expectation = 1*7/10 + 2*2/10+ 6*1/10
= 7/10 + 4/10 + 6/10
= 17/10 = $1.7 off
32 = 2x2x2x2x2
99 = 11x3x3
100 = 5x5x2x2
400 = 2x2x2x2x5x5
39 = 3x13
35 = 5x7
80 = 2x2x2x2x5
42 = 2x3x7
5 = 1x5
78 = 2x3x13
