Answer:
216 in2
Step-by-step explanation:
the area of the rectangle is
20(12)=240
area of the triangle is
4(6)= 24
so now we subtract, 240-24= 216 in2
y = 23/8
Please correct me if I'm wrong!! :)
Answer:
(a) $54
(b) $60
(c) $30
(d) $6.3
Step-by-step explanation:
Suppose a month has 30 days. Then the expected expense for the whole month is 30 times the expected expense at each day
(a) E[F] = 30*30%*$6 = 30*0.3*6 = $54
(b) E[T] = 30*50%*$4 = 30*0.5*4 = $60
(c) E[C] = 30*4%*$25 = 30*0.04*25 = $30
(d) Suppose all events are independent, the probability that she would spend on all 3 items on the same day is
P[F+T+C] = 0.3*0.5*0.04 = 0.006
So the expected expense she would make on all 3 items is
E[F+T+C] = 30*0.006*(6+4+25) = $6.3
1. (8x)/(7y) Letter C
2. let x = apples; let y = oranges;
x + y = 12
x = 2y
2y + y = 12
3y = 12
y = 4
oranges = 4
apples = 2* 4 = 8
3. B all real numbers
4. I did this already
5. t + h = 39
t = 2h
2h + h = 39
3h = 39
h = 13
2h = 26 LETTER D
6. Letter B
Answer:
B) 12p - 10
Step-by-step explanation:
J = 3p
A = 2(3p) = 6p
S = 3p - 10
add together:
3p + 6p + 3p - 10 = 12p - 10
