The value of P(A or B) is 0.47. Therefore, option B is the correct answer.

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.

Answer:

320√5 it simpleflied

Step-by-step explanation:

Answer:

Multiple Choice: 2 Points Each

Short Response: 4 Points Each

Step-by-step explanation:

This is a system of equations problem.

The way I solved it was by, first, organizing two equations.

m(23)+s(10)=86 and m(28)+s(5)=76

m = multiple-choice question points

s = short response question points

The first equation is your scores. m(23)+s(10)=86

You had 23 multiple choice questions and 10 short response questions. Your score on the test was 86.

The second equation is your friend's score. m(28)+s(5)=76

They had 28 multiple choice questions and 5 short response questions. They scored a 76 on the test.

Solve m(23)+s(10)=86;m(28)+s(5)=76

23m+10s=86 for m

Add -10s to both sides.

23m+10s+−10s=86+−10s

23m=−10s+86

Divide both sides by 23.

[tex]\frac{23m}{23}=\frac{-10s+86}{23}[/tex]

m=[tex]\frac{-10}{23} s+\frac{86}{23}[/tex]

Substitute [tex]\frac{-10}{23} s+\frac{86}{23}[/tex] for m in 28m+5s=76.

28m+5s=76

28( [tex]\frac{-10}{23} s+\frac{86}{23}[/tex])+5s=76

Simplify both sides of the equation.

[tex]\frac{-165}{23} s+\frac{2408}{23} =76[/tex]

Add [tex]\frac{-2408}{23}[/tex] to both sides.

[tex]\frac{-165}{23} s+\frac{2408}{23} +\frac{-2408}{23} =76+\frac{-2408}{23}[/tex]

[tex]\frac{165}{23} s=\frac{-660}{23}[/tex]

[tex]\frac{\frac{-165}{23}s}{\frac{-165}{23}}=\frac{\frac{-660}{23}}{\frac{-165}{23}}[/tex]

s=4

Substitute 4 for s in m=[tex]\frac{-10}{23}s+\frac{86}{23}[/tex]

m=[tex]\frac{-10}{23}s+\frac{86}{23}[/tex]

m=[tex]\frac{-10}{23}(4)+\frac{86}{23}[/tex]

Simplify both sides of the equation.

m=2

Answer:

m=2 and s=4

Answer:

|x-10 y-4|

Step-by-step explanation:

Let the initial position where the football is thrown up the air be x and y.

After the ball is thrown up the air it moves 10 feet west 4 feet south because of the gust of wind.

Therefore the change in x is by 10 feet west and is at the point x - 10 and the change in y is by 4 feet south and is at the point y - 4.

Thus the matrix representing the position of the football is |x-10 y-4|.

Vitamin C ___ 41 ________ 15 ______ 56

Zinc _______ 12 _________5 ______ 17

Echinacea __ 21 _________ 6 ______ 27

Total ______ 74 _________ 26 ____ 100

The ratio of people who took Echinacea :

Number of people who took Echinacea : total number of people in the survey

From the TOTAL column:

Number of people who took Echinacea = 27

Total Number of people in survey = 100

Hence, ratio equals :

but I still we help you if you are finding the area if a rectangle, you multiply the length by width. Like if the rectangle length is 7 and the width is 9 they you multiply it together which you get 63. If you are trying to find a area of a triangle then, duplicate the triangle and try to make a rectangle then caculate area of the rectangle and divide that area by two. Like this photo

The diver is approximately 276.5 feet away from the boat to the nearest foot.

There are three commonly used trigonometric identities.

Sin x = Perpendicular / Hypotenuse

Cosec = Hypotenuse / Perpendicular

Cos x = Base / Hypotenuse

Sec x = Hypotenuse / Base

Tan x = Perpendicular / Base

Cot x = Base / Perpendicular

We have,

We can use the tangent function to solve this problem.

Let x be the distance from the boat to the point directly below the scuba diver on the water's surface.

Then we have:

tan(39°) = x/356

Multiplying both sides by 356, we get:

x = 356 tan(39°)

x = 276.5

Therefore,

The diver is approximately 276.5 feet away from the boat to the nearest foot.

Answer:

0.9

Step-by-step explanation:

Since A and B are independent  hence;

P(A∩B) = P(A)P(B)

Given the following

P(A∩B) = 0.27

P(A) = 0.3

Required

P(B)

Substitute into the formula;

P(B) = P(A∩B)/P(A)

P(B) = 0.27/0.3

P(B) = 0.9

Hence the value of P(B) is 0.9

The value of P(B) is 0.9

Probabilities are used to determine the chances of events

The given parameters are:

P(A) = 0.3

P(A ∩ B) =0.27

To find the value of P(B), we make use of the following formula

P(A ∩ B) = P(A) * P(B)

So, we have:

0.27 = 0.3 * P(B)

Divide both sides by 0.3

P(B) = 0.9

Hence, the value of P(B) is 0.9
