Probability.
It has been estimated that about 30% of frozen chickens contain enough salmonella bacteria to cause illness if improperly cooked. A consumer purchases 12 frozen chickens. What is the probability that the consumer will have more than 6 contaminated chickens.
Answers
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:
[tex]P(X=x) = \ ^nC_x p^x(1-p)^{n-x}[/tex]
The probability that the consumer will have more than 6 contaminated chickens :-
[tex]P(X>6)=P(X=7)+P(X=8)+P(X=9)+P(X=10)+P(X=11)+P(X=12)\\\\=^{12}C_6(0.3)^6(0.7)^6+^{12}C_7(0.3)^7(0.7)^5+^{12}C_8(0.3)^8(0.7)^4+^{12}C_9(0.3)^9(0.7)^3+^{12}C_{10}(0.3)^{10}(0.7)^2+^{12}C_{11}(0.3)^{11}(0.7)^1+^{12}C_0(0.3)^{12}(0.7)^0[/tex]
[tex]=0.03860084306\approx0.0386[/tex] (simplified)
Hence, the required probability = 0.0386

The half-life of carbon 14 is 5, 730 years. How much would be left of an original 50-
gram sample after 2, 292 years?
Answers
Given :
The half-life of carbon 14 is 5,730 years.
To Find :
How much would be left of an original 50- gram sample after 2, 292 years.
Solution :
We know, rate law for first order reaction is given by :
[tex][A] = [A_o]e^{-kt}[/tex] ...1)
Here, [tex]A_o[/tex] is initial amount and [tex]A[/tex] is final amount.
And [tex]k = \dfrac{ln\ 2}{t_{0.5}}[/tex]
Putting value of half time in above equation, we get :
[tex]k = \dfrac{ln\ 2}{5730}\\\\k = 1.21\times10^{-4} \ /s[/tex]
Putting value of k in equation 1) , we get :
[tex][A] = 50\times e^{-1.21\times 10^{-4}\times 2292} = 37.89\ gm\\\\[/tex]
Hence, this is the required solution.

Find the measure of the missing angle.
Answers
Answer:
23º = x
Step-by-step explanation:
One straight line is ALWAYS 180º
(called a linear pair)
So your equation is
157º + x = 180
subtract x on both sides
and you get
23º
That is a question about angles.
The first thing that we should to note is that a line do a straight angle. A straight angle is an 180° angle.
So, we can say that the sum of the angle a and the angle of 157° is equal to a straight angle. Let's make and solve a equation:
[tex]a + 157 = 180\\a = 180 - 57\\a = 23[/tex]
Therefore, the missing angle is 23°.
I hope I've helped. :D

Answers
Answer:
change it into slope intercept form: y=3/2x-5
Step-by-step explanation:
the slope is 3/2
Answer:
m = [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
This is the answer because:
1) Use the slope-intercept form: y = mx + b to find the slope
1. The slope intercept form is y = mx + b where m is the slop and b is the y-intercept.
2. Subtract 3x from both sides of the equation:
-2y = 10 - 3x
3. Divide each term by -2 and simplify:
[tex]y=\frac{3}{2} -5[/tex]
4. Using the slope-intercept form, the slope is [tex]\frac{3}{2}[/tex]
Therefore, the answer is [tex]\frac{3}{2}[/tex]

A and B
Step-by-step explanation:
Basically all you have to do is combine those equations. How do you do that? You add/subtract the equations from each other, OR use substitution. It's hard to explain I recommend searching it up.
However, in this equation this is not what they are asking for. Only ONE equation has a solution when combined/substituted. Some have false solutions such as 3=0, which is not true. Some have infinite solutions where every number works.
Solving A:
This works because it actually gives us the value of y and x instead of giving us an incorrect statement.
Solving B:
This works as well!
Solving C:
This has no solution. It doesn't work and it ends up with 0 = -6, which is not true.
Solving D:
This has more than 1 solution.
Solving E:
This does not work, it has no solutions. It ends up with 0 = -2.
