Symbolab has a calculator that solves problems like that and works it out for you, to help understand it better :)
The probability that if 5 tires are inspected, exactly 2 have a defect is 0.021
<h3>How to calculate the probability</h3>
The given parameters are:
--- the proportion that contains defect
--- the sample size
-- the selected sample
The probability is then calculated as:
So, we have:
Hence, the probability that if 5 tires are inspected, exactly 2 have a defect is 0.021

Answer:
first we'll have to do it in order which is Parentheses, Exponents, Multiplication and Division (from left to right), Addition and Subtraction (from left to right)
Step-by-step explanation:
(22÷2-2.5)+(4-6+6)
(11-2.5)+(4-6+6)
(8.5)+(4)
= 12.5
Answer:
x^3+9x^2-3x^2-3
Step-by-step explanation:
You can use a various of methods but when you use the box method you multiply each separately.
Like you would multiply x² by x, 8x by x, -3 by x (thats the first row)
x² by 1, 8x by 1, -3 by 1 ( for the second row)
Then you get those final variables and combine like terms getting the answer above
Answer:
-x + 6
Step-by-step explanation:
(3x + 2) + (-4x + 4)
Distribute + into the bracket (-4x + 4). When you do so, + sign becomes -
3x + 2 - 4x + 4
Rearrange the expression
3x - 4x + 2 + 4
-x + 6
