The value of P(A or B) is 0.47. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favourable outcomes to the total number of outcomes of an event.
Given that, P (A) = 0.24, P(B) = 0.41, and P(A and B) = 0.18.
The formula to find P(A or B) is
P(A or B)=P(A)+P(B)-P(A and B)
P(A or B)=0.24+0.41-0.18
= 0.47
The value of P(A or B) is 0.47. Therefore, option B is the correct answer.

It took each student 30 minutes to set up the puppet show and twice as long to put everything away. The show was open for 3 hours. How much time did each student spend on this event?
Answer:
4 and 1/2 hours or 270 minutes
Step-by-step explanation:
Each student spend 30 minutes to set up the puppet show.
+30
They spent twice as long to put everything away.
+30 +30
Current total: 90 minutes
The show was open for three hours
+180 (60 minutes in an hour x 3 hours)
Current total: 270
Total: 270 minutes
OR
Divide 270 by 60 minutes in an hour, which would be 4.5 hours.
Answer: 1 hour and 30
Step-by-step explanation:
First, you multiply 30 minutes x2 and get 60. 60 minutes is an hour so now you have an hour. Then you add 30 minutes to that and get 1 hour and 30 minutes. Then, you subtract 3 hours minus 1 hour, and 30 minutes and get 1 hour and 30 minutes.

The first section has 90 sheep sorted into 3 rows how many sheep are in each row of the first section
Answer:
30 sheep
Step-by-step explanation:
Given that the first section has 90 sheep sorted into 3 rows, assuming that each row has equal number of sheep, then the number of sheep per row will be the total number of sheep available divided by the number of rows
= 90/3
= 30
It means there are 30 sheep per row

Step-by-step explanation:
The secant- tangent angle MLK is half the difference of the intercepted arcs, that is
[tex]\frac{1}{2}[/tex] (KN - KM) = 70° ( multiply both sides by 2 to clear the fraction )
KN - KM = 140°
KN - 61° = 140° ( add 61° to both sides )
KN = 201° → C

Step-by-step explanation:
1 Escritura unida
Según la NGLE se unen las palabras que se interpretan como una unidad y en las que, por tanto, la marca de plural solo afecta al último elemento:[1]
el bajorrelieve, los bajorrelieves
la mediapunta, las mediapuntas
En un buen número de casos, el primer elemento puede seguir teniendo individualidad para parte de los hablantes y admitir la marca del plural. La Gramática admite algunos de esos casos, de modo que las dos formas son posibles, que se escribirán unidas o separadas según se dé ese plural o no:
el puercoespín, los puercoespines; el puerco espín, los puercos espines
el arcoíris, los arcoíris; el arco iris, los arcos iris
el medioambiente, los medioambientes; el medio ambiente, los medios ambientes.
el pavorreal, los pavorreales; el pavo real, los pavos reales
La Gramática prefiere, como norma general, la forma en una palabra.

Two or more friends are collecting pop-can tabs. Natasha has 250 more pop-can tabs then Krystel, in total they have 880. how many pop-can tabs did each collect
Answer:
Krystal collected 315 pop-can tabs while Natasha collected 565 pop-can tabs.
Step-by-step explanation:
Let x be number of pop-can tabs Krystal collected
Krystal: x
Natasha: x + 250
x + x + 250 = 880
2x = 880 - 250
2x = 630
x = 315
Krystal: 315 pop-can tabs
Natasha: 315+250 = 565 pop-can tabs

a.) Find the surface area of a right prism with the following dimensions:
Length: 12 cm
Width: 7 cm
Height: 9 cm
Answer:
The total surface area of this object is 510 cm^2.
Step-by-step explanation:
Here L = 12 cm, W = 7 cm and H = 9 cm.
There are 2 panels 12 by 9 cm, 2 panels 12 by 7 cm, and 2 panels 7 by 9 cm. The combined areas are:
2(108 cm^2) + 2(84 cm^2) + 2( 63 cm^2) = 510 cm^2 total area
the measures of the angles of a triangle are shown in the figure below. solve for x
Answer:
x = 12
Step-by-step explanation:
81 + 57 + 2x + 18 = 180
156 + 2x = 180
2x = 24
x = 12
If the measures of triangle are 81⁰, 57⁰ and (2x+18)⁰then value of x is 12.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
The given triangle has three angles 81⁰, 57⁰ and (2x+18)⁰
According to the angle sum property.
The sum of three angles of triangle is 180⁰
81⁰+57⁰+(2x+18)⁰=180⁰
81+57+2x+18=180
We need to find the value of x of for eighty one plus fifty seven plus two times of x plus eighteen equal to one hundred eighty.
Add 81, 57 and 18
156+2x=180
Subtract 156 from both sides
2x=180-156
2x=24
Divide both sides by 2
x=12
Hence the value of x is 12.
