Answer:
Step-by-step explanation:
<u>The perimeters are equal:</u>
<u>Solve for x:</u>
- 12x - 24 = 4x
- 12x - 4x = 24
- 8x = 24
- x = 3

Answer:
∠A = 66.2°
Step-by-step explanation:
The sum of exterior angles of any polygon is 360°, so you have ...
(3x +10)° +(5x)° +(2x +4)° = 360°
10x +14 = 360 . . . . . . . . . . . . . . .collect terms, divide by °
x + 1.4 = 36 . . . . . . . . . divide by 10
x = 34.6
The interior angle at A is the supplement of the exterior angle there:
∠A = 180° -(3x +10)° = 180° -(3(34.6) +10)°
∠A = 66.2°
Answer:
Y= 2x - 8

Answer:
Step-by-step explanation:
Given that among employed women, 35% have never been married. Select 11 employed women at random.
a) probability for success in each trial p = 0.35 and no of trials = n =11
b) the probability that exactly 3 of the 11 women in your sample have never been married=
P(X=3) =
c) the probability that 2 or fewer women have never been married
=
