The security system in a house has two units that set off an alarm when motion is detected. Neither one is entirely reliable, but one or both always go off when there is motion anywhere in the house. Suppose that for motion in a certain location, the probability that detector a goes off and detector b does not go off is 0. 25, and the probability that detector a does not go off is 0. 35. What is the probability that detector b goes off?.
Answers
The probability that detector B goes off is 0.75
The probability of an event is known to be the likelihood or chance for an event to occur.
From the given information let consider:
A = the time when detector A goes off, andB = the time when detector B goes offSince one or both of them always goes off, then:
P(A or B) = 1∴
Their complements will be zero, i.e.
P(A' and B') = 0Similarly, we are given that:
P(A and B') = 0.25Then;
P(A') = 0.35∴
The set probability for A will be:
P(A) = 1 - P(A')
P(A) = 1 - 0.35
P(A) = 0.65
Finally, the probability that detector B goes off can be computed as:
P(B) = P(A) P(B|A) +P(A') P(B|A')
P(B) = P(A) (1 - P(B|A')) + P(A') (1 - P(B'|A')
[tex]\mathbf{P(B) = P(A) (1-\dfrac{P(A \ and \ B')}{P(A)}) +P(A') (1 - \dfrac{P(A' \ and B')}{P(A')})}[/tex]
[tex]\mathbf{P(B) = 0.65 (1-\dfrac{0.25}{0.65}) +0.35 (1 - \dfrac{0}{0.35})}[/tex]
P(B) = 0.75

What are Parents?
It would seem simple to define the term "parenting" as follows: Parenting is the act of nurturing, supporting, encouraging, directing, guiding, and loving a child or children from infancy to adulthood.
Consistency and routine are key components of good parenting, which provides kids with a sense of control. Redundancy becomes the goal for parents because good parenting emphasizes helping children become independent. A style of parenting that takes into account the age and developmental stage of the kid is good parenting.
The biological parents of a kid are typically the father and mother whose DNA the child carries. Although they do not need to be blood relatives, legal parents have a family link to the kid by law, such as in the case of an adopted child.
Hence, He would be beaten if he was ever late to work.

Explanation:
Two numbers differ by 8 if their product is 713 then the sum of the two numbers is.
Answers
The sum of the two numbers is equal to 70.
Let the first number be x.Let the second number be y.In this exercise, you're required to find two numbers by translating the word problem into an algebraic expression and then solving for the unknown variables (x and y).
Translating the word problem into an algebraic expression, we have;
Two numbers differ by 8:
[tex]x-y=8[/tex] ....equation 1.
The product of the two numbers is 713:
[tex]xy=713[/tex] ....equation 2.
To calculate the sum of the two numbers:
First of all, we would solve for each of the unknown variables (x and y).
From eqn. 1, we have:
[tex]x=8+y[/tex] ....equation 3.
Substituting eqn. 3 into eqn. 2, we have:
[tex]y(y+8)=713\\\\y^2+8y=713\\\\y^2+8y-713=0[/tex]
Solving the quadratic equation by factorization, we have:
[tex]y^2-31y +23y-713=0\\\\y(y-31)+23(y-31)=0\\\\(y+23)(y-31)=0[/tex]
y = -23 or 31.
For the value of x, when y = 31:
[tex]x=8+31[/tex]
x = 39
Now, we can calculate the sum of the two numbers:
[tex]x+y=39+31=70[/tex]

Select the correct answer. Consider these functions. F(x) = -2x − 5 g(x) = x − 2 which graph shows the composite function (f ◦ g)(x)? a. B. C. D.
Answers
Composite functions are functions formed by combining multiple functions that may or may not be the same.
The composite function (f o g)(x) is -2x - 1
The functions are given as:
[tex]f(x) =-2x - 5[/tex]
[tex]g(x) = x - 2[/tex]
The composite function (f o g)(x) is calculated using:
[tex](f\ o\ g)(x) = f(g(x))[/tex]
Given that:
[tex]f(x) =-2x - 5[/tex]
Substitute g(x) for x in the above equation
[tex]f(g(x)) =-2g(x) - 5[/tex]
Substitute [tex]g(x) = x - 2[/tex]
[tex]f(g(x)) =-2(x - 2) - 5[/tex]
Expand
[tex]f(g(x)) =-2x + 4 - 5[/tex]
So, we have:
[tex]f(g(x)) =-2x -1[/tex]
Hence, the composite function (f o g)(x) is -2x - 1
