if A and B are events with P(A) = 0.2, P(A OR B) = 0.61, and P(A AND B) = 0.19, find P(B).
Answer:
0.41
Step-by-step explanation:
p (A) = 0.2
P (B) =?
P (A or B) = 0.61
but P (A or B) = P (A) + P (B)
therefore P(B) = P (A or B) - P(B)
= 0.61 - 0.2
= 0.41
Star Wars is showing in two adjacent theaters. One
theater sells 80 adult tickets and 50 child tickets and
collects $1310. The other theater sells 98 adult tickets and
50 child tickets and collects $1526. What is the cost for
each adult ticket and each child ticket? Write and solve a
system of equations.
Answer:
700$
Step-by-step explanation:
A car enthusiast learns that a particular model of car, which costs $34,411 new, loses 25% of its value every year. How much will the car be worth in 6 years?
The worth of the car in 6 years would be $25,808.25.
What will be the worth of the car in 6 years?The car is depreciating with the passage of time. When an asset depreciates, it costs less and less as a result of decline in value.
The exponential equation that can be used to determine the value of the car is:
Value of the car in 6 years = value of the car today x (1 - loss in value)^number of years
= $34,411 x (1 - 25%/100)
$34,411 x (1 - 0.25)
$34,411 x 0.75 = $25,808.25

Part 5 :-Here,
Two non parallel lines are intersected by three parallel lines .These three parallel lines are also parallel to each other.By using basic proportionality theorem
It states that the line which is parallel to one side of triangle intersects the other two sides then the other two sides are divided in the same ratios. That is,[tex]\sf{\dfrac{ x }{ x + 16 }}{\sf{=}}{\sf{\dfrac{9}{12 + 9}}}[/tex]
By cross multiplication ,
[tex]\sf{ 21x = 9( x + 16)}[/tex]
[tex]\sf{ 21x = 9x + 144}[/tex]
[tex]\sf{ 21x - 9x = 144}[/tex]
[tex]\sf{ 12x = 144}[/tex]
[tex]\sf{ x = }{\sf{\dfrac{ 144}{12}}}[/tex]
[tex]\bold{ x = 12}[/tex]
Hence, The value of x is 12

Here, JL bisects Angle J in ΔHJK It means Angle JHL = Angle JKLThe length of HJ = 12 , JK = 15 , HL = 18 Therefore,In triangle JHL and In triangle JKL
By using similarity theorem
It states that if the two triangles are similar then the corresponding sides of triangle are in proportion and corresponding angles are equal That is,[tex]\sf{\dfrac{ JH }{ JK}}{\sf{=}}{\sf{\dfrac{HL}{KL}}}[/tex]
Subsitute the required values,
[tex]\sf{\dfrac{ 12 }{ 15 }}{\sf{=}}{\sf{\dfrac{18}{KL}}}[/tex]

The area of a rectangular school yard is 3,195 square meters. The perimeter is 232 meters. What are the dimensions of the school yard?
Answer:
71 m x 45 m
Step-by-step explanation:
Length = x, Width = y
x * y = 3,195
2(x + y) = 232, so
x + y = 232/2 = 116, they y = 116 - x
x * (116 - x) = 3,195
116x - x² = 3,195
x² - 116x +[tex]x = \frac{116\pm\sqrt{116^2-4*3195}}{2}[/tex] = 71, 45

Area of a triangle: A = 1/2*b*h (base = 6, height = 6)
A = 1/2 * 6 * 6
A = 1/2 * 36
A = 18 square inches
Since there are two triangles, it would be 18 * 2 = 36 square inches
Area of a rectangle: A = l*w (length = 9, width = 9)
A = 9 * 9
A = 81 square inches
Add the two areas together:
b) 36 + 81 = 117 square inches

find the value of x y and z in the rhombus below
Answer:
x = y = 13, z = 18
Step-by-step explanation:
6x + 8 = 86
6x = 86 - 8 = 78, so x = 78/6 = 13
7y + 3 + 86 = 180
7y = 180 - 86 - 3 = 91
y = 91/7 = 13
5z + 4 + 86 = 180
5z = 180 - 86 - 4 = 90
z = 90/5 = 18

(6.) The point A(-5,12) lies on the circle whose equation is x + y2 = 169. What is the secant of
an angle drawn in standard position whose terminal rays passes through A?
The secant of the angle through a point (-5, 3) is -13/5
Equation of a circleThe equation of a circle with center (0,0) is given by
x² + y² = r² where r = radius of circle
Now, comparing this to the equation of the given circle x² + y² = 169,
⇒ r² = 169
r = √169
r = 13
Secant of angle
The secant of the angle through a point (x, y) is secФ = r/x where
r = radius of circle and x = x-coordinate of pointNow for the point A(-5,12), x = -5.
Since r = 13
secФ = r/x
= 13/-5
= -13/5
So, The secant of the angle through a point (-5, 3) is -13/5

graphing an integer function and finding its range for a given domain
Answer:
{-3, -1, 1, 3}
Step-by-step explanation:
The range is the set of function values corresponding to the values in the domain. They are generally sorted into numerical order.
range = {-3, -1, 1, 3}
__
Each value is found by evaluating the function at the domain value:
f(-1) = 1 -2(-1) = 3
f(0) = 1 -0 = 1
f(1) = 1 -2(1) = -1
f(2) = 1 -2(2) = -3

B a pair of alternate exterior angles with measures of 72° and 72°
C a pair of corresponding angles with measures of 30° and 30°
D a pair of same side interior angles with measures of 50° and 50°
Answer:
Option DStep-by-step explanation:
The first three options are correct.
The last option is incorrect as same side interior angles are supplementary, so they should sum to 180° but in the given option their sum is 100°.
Answer:
D
Step-by-step explanation:
Smae side interior angles are supplementary i.e they have sum 180°
If one is 50°
Then other one must be 180-50=130°
