Given P(A)=0.5P, (A)=0.5, P(B)=0.24, P(B)=0.24, and P(A and B)=0.2, find the value of P(A or B), rounding to the nearest thousandth, if necessary.
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.5 + 0.24 - 0.2
P(A or B) = 0.54

Can someone help me with this??
Answer:
the second option, a=3 b=3 c=5
Step-by-step explanation:
first I would change them both into an improper fraction:
9/2 divided by 5/4
dividing is the same thing as mulitiplying by the reciprocal of the second number. so you would mulitply 9/2 x 4/5 = 36/10 and then you simplify back to a mixed number 3 6/10, 6/10 can be reduced so the final answer is 3 3/5.
Continue the pattern by filling in the next 3 terms
-5, -2, 1,
Answer:
4, 7, 10
Step-by-step explanation:
There is a common difference d between consecutive terms, that is
d = - 2 - (- 5) = 1 - (- 2) = 3
To obtain a term in the sequence add d = 3 to the previous term, then
a₄ = a₃ + 3 = 1 + 3 = 4
a₅ = a₄ + 3 = 4 + 3 = 7
a₆ = a₅ + 3 = 7 + 3 = 10
What is the y-intercept of the line represented by -2x + 3y = 12?
F -4
H 4
G 1/4
J 12
Answer:
The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
Step-by-step explanation:
The graph of 2x + 3y = 12 crosses the x-axis at (6, 0), so its x-intercept is 6. The graph of 2x + 3y = 12 crosses the y-axis at (0, 4), so its y-intercept is 4.
Solve:
-1/4a - 4 = 4
Answer:
a = -12
Step-by-step explanation:
-1/4a - 4 = 4
(-1/4a / -1/4) - 4 = (4 / -1/4)
a - 4 = -16
(a - 4 + 4) = -16 + 4
a = -12
I might have made some mistake but if my memory is right this is how you solve it.

Step-by-step explanation:
what's the square root of 25 in **simplest radical form**
Answer:
5
Step-by-step explanation:
The square Root of 25 in its simplest form means to get the number 25 inside the radical √ as low as possible.
25 is a perfect square, which means that you can simply calculate the square Root of 25 to get the answer. 5 times 5 equals 25. Thus, the square Root of 25 in simplest radical form is:
5
solve for x in the following question 2x - 3 = 1
Answer:
x = 2
Step-by-step explanation:
2x-3 = 1
use addition property of equality (add 3 to each side to keep balance)
2x = 4
use division property of equality (divide both sides by 2)
4/2 = 2
so,
x = 2

Marie and Jorge are both trying to lose weight. After 3 months they compared their weight loss. Marie’s weight went from 175 to 150. Jorge’s weight went from 190 to 180. Which statements are true regarding their weight loss? Select three options. WILL GIVE BRAINLIEST +20 POINTS
ill tell em to ya right now
Jorge’s weight change was approximately 5%.
Marie’s weight change was approximately 14%.
Marie had the greater percent change.
Jorge had the greater percent change.
Marie’s weight change was approximately 1.4%.
#edge2021
Answer:
1 ,2, and 3
Step-by-step explanation:
Jorge's weight percent decrease is (190-180)÷190, or amount of change/original amount. Simplified, 10÷190=5.2637157894...%, approximately equal to 5%. The first option is correct. Marie's percent decrease is (175-150)÷175. Simplified, that is 25÷175=14.2857142857...%, which is about 14%. The second option is correct. Clearly, we can tell that Marie had the greater percent change, about 14% to about 5%. Also clearly, Jorge did not have the greater percent change, so we can tell Option 4 is wrong. We already know that Jorge's change is about 5% and Marie's is about 14%, so they can't be about 0.5% or about 1.4%. Options 5 and 6 are incorrect. The correct answers are 1, 2, and 3.
Hope this helps you!
Explain the three different types of solutions you can get when solving a system of
equations.
Answer:
There are three possible outcomes for a system of linear equations: one unique solution, infinitely many solutions, and no solution.
Step-by-step explanation:
9514 1404 393
Answer:
no solutionsa finite non-zero number of solutionsinfinite solutionsStep-by-step explanation:
1. No Solutions
This case arises when the equations are inconsistent. No values of the variables can satisfy all of the equations. An example is ...
y = xy = x+1__
2. Finite Number of Solutions
The number of distinct solutions depends on the degree of the system and the domain being considered. For example, an n-th degree polynomial equation in one variable will always have n solutions in the domain of complex numbers. However, it may or may not have any real-number solutions. (The question here has no context, so we have to assume it is about any system of equations of any degree or nature (rational, polynomial, exponential, mixed, or other.))
__
3. Infinite solutions
An under-specified system, such as a system of 3 equations in 4 variables, may have an infinite number of solutions. In such a system, one or more of the variables may be allowed to assume any value. Systems that have dependent equations will fall into this category.
The first number plus the second number equals 83, the first number
minus the second number equals 33. What are the two numbers?
Answer:
I hope this helps
Step-by-step explanation:
So the way to handle a problem like this is to rewrite the three numbers in terms of their relationship to one of the three numbers. Let's call the numbers x, y, and z, where x is the first number, y is the second, and z is the third.
We know x + y + z = 83.
Since the third number is twice the second, we say that z = 2y.
Since the second number is seven less than the first, we say that y = x - 7. We can rewrite this as x = y + 7.
Now all three can be written in terms of y.
x + y + z = 83
(y + 7) + y + 2y = 83
4y + 7 = 83
4y = 76
y = 19
The second number is 19. The first is 19 + 7 or 26, and the third is 2 times 19 or 38.
A check reveals that 26 + 19 + 38 = 83.

A parabola has x-intercepts of (2, 0) and (-4, 0) and has a leading coefficient of 1. What is the equation of the parabola in standard form? *
9514 1404 393
Answer:
y = x^2 +2x -8
Step-by-step explanation:
For x-intercepts p and q, factors of the parabola's equation are (x-p) and (x-q). Since the leading coefficient is 1, those are the only factors.
y = (x -2)(x -(-4))
y = (x -2)(x +4) = x(x +4) -2(x +4) . . . . use the distributive property
y = x^2 +4x -2x -8 . . . . use the distributive property again
y = x^2 +2x -8 . . . . . . . .equation in standard form
