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

Answer:

All Triangles are closed figure polygons that have three straight sides

Step-by-step explanation:

All 2D shapes are plane figures so this one is false. Three right angles are greater than 180 so this is fake. Polygon and closed figures are shapes with three or more closed sides. And triangles have straight sides.

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

Step-by-step explanation:

Between numbers 1 - 11, the evens are 2, 4, 6, 8, and 10. Therefore, there are 5 evens.

Out of the eleven choices in the bag, there are 5 possible choices to be picked out of the 11 total choices.

Therefore, the probability of drawing an even number over the number of choices is 5/11.

Answer:

C. The mean will increase and ty e median will remain the same.

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:

|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|.

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.
