Step-by-step explanation:
V=πr^2h
= 3.14 * 11^2 * 20
= 2420π or 7598.80
Answer:
0.8213
Step-by-step explanation:
-This is a binomial probability problem given by the function:

Given that n=21 and p=0.2, the probability that she experience a delay on at least 3 days is calculated as:

Hence, the probability that she experience delay on at least 3 days is 0.8213
Answer: I got 2/9 but im not sure if its right
Step-by-step explanation:
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
Let's first establish that the shape is a triangle meaning that the following formula is applicable as displayed below:
Angle sum of a triangle = 180°
As well as this, the shape is an equilateral triangle meaning that each angle of the triangle is equivalent in value. Also, the following formula is also applicable as displayed below:
Each angle of an equilateral triangle = the same value
Therefore:
Each angle of an equilateral triangle = angle sum of a triangle ÷ no. of angles in a triangle = 180° ÷ 3 = 60°
Based on this, the following is applicable:
2x - 4 = 60°
2x = 60 + 4
2x = 64
x = 64 / 2
x = 32°
ANSWER:
Therefore, the answer is:
The value of ( x ) is 32°
