Answer:
B x=2 y=6
Step-by-step explanation:
For ABCD to be parallelogram, following conditions should be satisfied:
2x - 0 = x + 2 & 4y - 8 = y + 10
2x - 0 = x + 2
2x - x = 2
x = 2
4y - 8 = y + 10
4y - y = 10 + 8
3y = 18
y = 18/3
y = 6
The first hexagon: 2, 2, 3, 4, 6, 7
The second hexagon: 3, 3, a, b, c, d
The hexagons are similar. Therefore the sides are in proportion.
<em>multiply both sides by 3</em>

<em>multiply both sides by 4</em>

<em>multiply both sides by 6</em>

<em>multiply both sides by 7</em>

The perimeter:

Divide the circumference over the diameter
(circumference)/(diameter) = (15.7)/(5) = 3.14
This is approximately equal to pi
Answer: 5
Step-by-step explanation:
160/2= 80 1
80/2= 40 2
40/2=20 3
20/2=10 4
10/2=5 [5]
Answer:
probability that exactly 4 out of 9 questions are correct is 0.111
Step-by-step explanation:
Given data:
Test consist of multiple choice question which as 4 choices
Total number of answer randomly = 9
Probability of having 4 answer correctly is calculated as
p = probability of having particular question is answered in correct way
= 1/4 = 0.25
q = probability of having particular question is answered incorrectly
= 3/4 = 0.75
Binomial expansion is beneficial in various situations at which numerical variables are present that are countable or whole numbers
probability that exactly 4 out of 9 questions are correct


= 0.111
