Answer:
Step-by-step explanation:
1). ∠7 ≅ ∠ 2 (alternate exterior)
m∠7 = m∠2 = 30°
2). ∠4 and ∠1 are supplementary angles
m∠1 = 180° - 72° = 108°
Answer:
16 had the cheaper ticket
Step-by-step explanation:
Let the number of 75cents tickets be x
Let the number of $1.25 tickets be y
Since the total tickets is 40, hence;
x+y =40 .... 1
Also if some are sold at 75 cents and the rest at $1.25 with total of $42 earned, then;
0.75x+1.25y = 42... 2
From 1
x = 40-y
Substitute into 2;
0.75(40-y)+1.25y = 42
30-0.75y+1.25y = 42
30+0.5y = 42
0.5y =42-30
0.5y = 12
y = 12/0.5
y = 24
Since x = 40-y
x = 40-24
x = 16
The number of cheaper ticket are 16
Good day my friendly person, I am sorry to inform you that I will not be able to provide an answer because the picture is simply too blurry.
Answer: P(Upper E' prime) = 0.06
Step-by-step explanation:
Not happen:P(Upper E prime) = 0.94
Happen: P(Upper E' prime) = ?
P(Upper E' prime) + P(Upper E' prime) = 1
Therefore
P(Upper E' prime) + 0.94= 1
P(Upper E' prime) =1- 0.94
P(Upper E' prime) = 0.06
