Find the indicated probability.
If P(A or B) = 0.8, P(A) = 0.4, and P(A and B)= 0.15, find P(B).
P(B)=
(Simplify your answer. Type an integer or a decimal.)
Answer:
[tex]P(B) = 0.55[/tex]
Step-by-step explanation:
Given
[tex]P(A\ or\ B) = 0.8[/tex]
[tex]P(A) = 0.4[/tex]
[tex]P(A\ and\ B) = 0.15[/tex]
Required
Find P(B)
In probability, we have:
[tex]P(A\ or\ B) = P(A) + P(B) - P(A\ sd B)[/tex]
Substitute values
[tex]0.8 = 0.4 + P(B) - 0.15[/tex]
Collect Like Terms
[tex]P(B) = 0.8 - 0.4 + 0.15[/tex]
[tex]P(B) = 0.55[/tex]

Answer:
Rocco mowed 1 lawn a week.
Step-by-step explanation:
If Carly mowed 18 lawns in six weeks that’s 3 lawns a week and 3-2=1.
Thus Rocco mowed 1 lawn a week.
14. The area of a rectangle is 375 square inches and it’s perimeter is 80 inches. Find both the length and width.
Answer:
Length [tex]=25[/tex] inches
Width [tex]= 15[/tex] inches
Step-by-step explanation:
Let [tex]l[/tex] = length of rectangle, [tex]w[/tex] = width of rectangle
Given the area and the perimeter of the rectangle, we can write:
[tex]lw = 375[/tex]
[tex]2l+2w=80[/tex]
So:
[tex]l+w = 80\div2[/tex]
[tex]=40[/tex]
[tex]l=40-w[/tex]
Now, we can use substitution to find the value of [tex]w[/tex]:
[tex]lw = 375[/tex]
[tex](40-w)w = 375[/tex]
[tex]40w-w^2 = 375[/tex]
[tex]375+w^2-40w = 0[/tex] (Quadratic equation)
[tex](w-15)(w-25) = 0[/tex]
∴ [tex]w = 15, 25[/tex]
We can use substitution again to find the value of [tex]l[/tex]
[tex]lw = 375[/tex]
[tex]l=375\div w[/tex]
[tex]=25,15[/tex]
∵ Length usually refers to the longer side of a rectangle, ∴ length [tex]=25[/tex] inches and width [tex]=15[/tex] inches.
Hope this helps :)

Is (-4, 2) a solution of 4x + 5y 3-7?
PLEASE HELP WILL MARK BRANLIEST
Please note that your equation sounds a little unclear. But, I am assuming that your equations in two ways and solving both equations.
[tex]4x+5y^3=-7[/tex]
[tex]4x+5y=-37[/tex]
so, I will solve both of them.
Answer:
Please check the explanation.
Step-by-step explanation:
1)
[tex]4x+5y^3=-7[/tex]Assuming the equation
[tex]4x+5y^3=-7[/tex]
substituting x = -4 and y = 2
[tex]4\left(-4\right)+5\left(2\right)^3=-7[/tex]
[tex]-16+2^3\cdot \:\:5=-7[/tex]
[tex]-16+40=-7[/tex]
[tex]24=-7[/tex]
False!
The sides are not equal!
Since (-4, 2) does not satisfy the equation, therefore (-4, 2) is not a solution of [tex]4x+5y^3=-7[/tex].
2)
[tex]4x+5y=-37[/tex]
Assuming the equation
[tex]4x+5y=-37[/tex]
substituting x = -4 and y = 2
[tex]4\left(-4\right)+5\left(2\right)=-37[/tex]
[tex]-16 + 10 = -37[/tex]
[tex]-6=-37[/tex]
False!
The sides are not equal!
Since (-4, 2) does not satisfy the equation, therefore (-4, 2) is not a solution of [tex]4x+5y=-37[/tex].

Which lengths represent the sides of a right triangle?
A)
7, 24, 25
B)
8, 12, 16
C)
8, 24, 25
D)
9, 12, 13
Answer:
A
Step-by-step explanation:
Using Pythagorean theorem (a^2+b^2=c^2) you just plug them in. The hypotenuse is always the longest side so that would be 25. Then it doesn’t matter which side is a or b. 7^2+24^2=625
Then do the square root of 625.

Solve using substitution.
y = 3x – 6.
y = 2x – 1
Answer:
x = 1 and y = 3
Step-by-step explanation:
To use substitution, you want to substitute something for another variable. So lets take the first equation and solve for y
2x - y = -1
2x = y - 1
2x + 1 = y
Now we can substitute 2x + 1 for y in the other equation
3x + 2x + 1 = 6
5x = 5
x = 1
now that we have x, we can get y
2(1) - y = -1
2 - y = -1
2 = y - 1
3 = y
So x = 1 and y = 3

what are the root functions?
What’s the value of x? :/
Answer:
[tex] x = 27 [/tex]
Step-by-step explanation:
According to congruent chords and arcs theorem, if [tex] \overline{XY} \cong \overline{ZY} [/tex] then [tex] \arc{XY} \cong \arc{ZY} [/tex].
This means that [tex] \arc{XY} = \arc{ZY} = (6x - 20) degrees [/tex]
Thus:
[tex] \arc{XY} + \arc{ZY} + \arc{ZX} = 360 [/tex] (full circle = 360°)
[tex] \arc{XY} = (6x - 20) [/tex]
[tex] \arc{ZY} = (6x - 20) [/tex]
[tex] \arc{ZX} = 76 [/tex]
Plug in the values into the equation
[tex] (6x - 20) + (6x - 20) + 76 = 360 [/tex]
[tex] 6x - 20 + 6x - 20 + 76 = 360 [/tex]
Add like terms
[tex] 12x + 36 = 360 [/tex]
Subtract 36 on both sides
[tex] 12x = 360 - 36 [/tex]
[tex] 12x = 324 [/tex]
Divide both sides by 12
[tex] x = 27 [/tex]
