Answer: 0.0386
Step-by-step explanation:
Given: The probability hat the frozen chickens contain enough salmonella bacteria to cause illness if improperly cooked : p= 0.30
Sample size : n = 12
Let x = Number of contaminated chickens
Here , two outcomes for any chicken (either contaminated or not) , so it follows binomial distribution.
Binomial probability formula:
The probability that the consumer will have more than 6 contaminated chickens :-

<em> (simplified)</em>
<em />
Hence, the required probability = 0.0386
B)
2x6= 12
2x7= 14
2x8= 16
2x8= 18
Given:
The expressions are:



To find:
The value of given expression by using integer tiles.
Solution:
We have,

Here, both number are positive. When we add 6 and 3 positive integer tiles, we get 9 positive integer tiles as shown in the below figure. So,

Similarly,

Here, 6 is positive and -4 is negative. It means we have 6 positive integer tiles and 4 negative integer tiles.
When we cancel the positive and negative integer tiles, we get 2 positive integer tiles as shown in the below figure. So,


Here, 6 is positive and -6 is negative. It means we have 6 positive integer tiles and 6 negative integer tiles.
When we cancel the positive and negative integer tiles, we get 0 integer tiles as shown in the below figure. So,

Therefore,
.
The answer would be 15.24cm
Answer: 380
Step-by-step explanation: Create an equation, so if 65% waved then 35% of the total (x) didn't wave, which are 133 people, so .35x=133, solve for x so x=133/.35 so x=380
