Answer:
77
Step-by-step explanation:
Total customers: 26+42+33+24+40 =
165
The number of customers that bought 5-6 = 33
The probability would be 33/165
Total customers that bought fewer than 5 = 26+42 = 68
The probability is 68/165
Answer:
72
Step-by-step explanation:
44- -28
Answer:
The rightmost figure
Step-by-step explanation:
That is the only figure where there are 4 points of intersection. It is a rhombus inscribed in a square
The slope-intercept form of the equation of a straight line:
y=mx+b
m=slope
Therefore; in this equation (y=3x+5); m=3
a)
6x+2y=12
2y=-6x+12
y=-6/2 x + 12/2
y=-3x+6 ⇒ m=-3≠3 (this line is not parallel to "y=3x+5")
b)
-3x+y=8
y=3x+8 ⇒ m=3 (this line es parallel to "y=3x+5")
c)
3y=9x
y=9/3 x
y=3x ⇒ m=3 (this line is parallel to "y=3x+5")
d)
y=-x ⇒ m=-1≠3 (this line is not parallet to "y=3x+5")
Therefore; "-3x+y=8" and "3y=9x" are parallel to "y=3x+5".
