The value of probability P (A or B) is,

⇒ P (A or B) = 45

We have to given that;

To find the probability that either event will occur.

Now, By given figure we get;

P (A) = 25 + 5

P (A) = 30

P (B) = 5 + 15

P (B) = 20

P (A and B) = 5

Since, The formula is,

⇒ P (A or B) = P (A) + P (B) - P (A and B)

Substitute all the values we get;

⇒ P (A or B) = 30 + 20 - 5

⇒ P (A or B) = 50 - 5

⇒ P (A or B) = 45

Therefore, The value of probability P (A or B) is,

⇒ P (A or B) = 45

Answer:$2050.

Step-by-step explanation:

To find out how much a person will pay for renting a car for one day and driving it 100 miles using the given equation, you can substitute x = 100 into the equation y = 50 + 20x and solve for y:

y = 50 + 20x

y = 50 + 20(100)

y = 50 + 2000

y = 2050

Therefore, a person who rents a car for one day and drives it 100 miles will pay $2050.

Answer:

55°

Step-by-step explanation:

if angle 4 = 105°, then angle 3 must be 180 - 105 = 75° (angles in straight line add up to 180°).

angles in a triangle also add up to 180°.

so we expect angle 2 to be 180 - angle 6 - angle 3

= 180 - 50 - 75

= 55°.

The estimated height of the older snail's shell is approximately 13 centimeters.

To estimate the height of the older snail's shell, we can use the concept of proportional relationships between the heights and volumes of the snail shells.

Let's denote the height of the older snail's shell as "h" (in centimeters). We can set up a proportion based on the relationship between the heights and volumes of the snail shells:

(height of younger snail) / (volume of younger snail) = (height of older snail) / (volume of older snail)

Substituting the given values:

3.9 / 3 = h / 10

To solve for "h," we can cross-multiply and then divide:

3 * h = 3.9 * 10

3h = 39

h = 39 / 3

h ≈ 13

The estimated height of the older snail's shell is approximately 13 centimeters.

The measure of the angle ∠ADC is 36°.

Given that a circle T, the inscribed angle ∠ABC = 72°, we need to find the measure of the angle ∠ADC,

So, according to the inscribed angle theorem,

2 ∠ABC = arc AC

arc AC = 144°

Now, since the whole circumference is 360°,

So,

arc ADC = 360° - arc AC

arc ADC = 216°

So,

∠ADC = 1/2 [arc ADC - arc AC]

∠ADC = 1/2 [216° - 144°]

∠ADC = 36°

Hence the measure of the angle ∠ADC is 36°.

The number of new health units is 937, and the number of improved health units is 1,137.

The number of improved health units exceeds the new ones by 200. In other words, I = N + 200.

We also know that the total number of health units counted in the report is 2,074.

Therefore, we have the equation N + I = 2,074.

Substituting the value of I from the first equation into the second equation, we can solve for N:

N + N + 200 = 2,074

2N + 200 = 2,074

2N = 1,874

N = 937

Now, we can substitute the value of N back into the first equation to find I:

I = N + 200

I = 937 + 200

I = 1,137

Therefore, the number of new health units is 937, and the number of improved health units is 1,137.

The solution to the system of equations is x = 2 and y = -1.

To solve the system of equations:

2x - 5y = 9 ...(1)

3x + 4y = 2 ...(2)

Multiplying equation (1) by 4 and equation (2) by 5, we can eliminate the variable 'y':

8x - 20y = 36 ...(3)

15x + 20y = 10 ...(4)

Adding equation (3) and equation (4), the 'y' terms cancel out:

(8x - 20y) + (15x + 20y) = 36 + 10

23x = 46

Dividing both sides of the equation by 23, we find:

x = 2

Plugging the value of 'x'

2(2) - 5y = 9

4 - 5y = 9

Subtracting 4 from both sides of the equation:

-5y = 9 - 4

-5y = 5

y = -1

The man rotated the window by 45 degrees and covered one of the diagonals, resulting in a smaller square window with sides measuring 1 meter.

The man achieved the transformation of his square window by dividing it into two equal halves and boarding up one of them.

Let's analyze the steps he took to accomplish this:

Initially, the man had a square window with sides measuring 1 meter

This means that the window had an area of 1 square meter (1m x 1m = 1m²).

To reduce the amount of light coming through the window, the man decided to board up half of it.

This implies that he covered one of the equal halves of the square window, while leaving the other half open.

By boarding up half of the window, he effectively blocked off half of the area of the square window.

Since the original window had an area of 1 square meter, boarding up half of it reduces the effective area to 1/2 square meter (1m² ÷ 2 = 1/2m²).

The remaining open half of the window still retains its square shape, with sides equal to 1 meter.

Therefore, the man ends up with a square window that measures 1 meter in height and 1 meter in width, but with an area of only 1/2 square meter.

In summary, the man achieved the transformation by boarding up half of the square window, effectively reducing its area to half of the original size while maintaining the same dimensions for the remaining open half. This manipulation allows him to control the amount of light entering his house while preserving the square shape of the window.

Only Priya's statement is correct based on the expected value. The expected value of X represents the average or mean number of successful free-throws that the player makes. Therefore, it is correct to say that the probability of making a free-throw is 0.80 on average. Hadley's statement about the next set of 2 free-throws is incorrect because the expected value does not tell us exactly how many free-throws the player will make in a given set, but rather what the average or expected number of successful free-throws will be over a series of trials.

Answer: 97 degrees

Step-by-step explanation: 180-83=97

The calculated values of the expected values are E(2x) = 8/3 and E(x²) = 2

From the question, we have the following parameters that can be used in our computation:

f(x) = 0.5x, 0 < x < 2

The expected value of 2x is calculated as

E(2x) = ∫2x * f(x) dx

So, we have

E(2x) = ∫2x * 0.5x dx

Evaluate

E(2x) = ∫x² dx

Integrate the function

So, we have

E(2x) = x³/3

Using the boundaries, we have

E(2x) = (2 - 0)³/3

Evaluate

E(2x) = 8/3

The expected value of x² is calculated as

E(x²) = ∫x² * f(x) dx

So, we have

E(x²) = ∫x² * 0.5x dx

Evaluate

E(x²) = ∫0.5x³ dx

Integrate the function

So, we have

E(x²) = 0.5x⁴/4

Using the boundaries, we have

E(x²) = 0.5 * (2 - 0)⁴/4

Evaluate

E(x²) = 2

Hence, the expected values are E(2x) = 8/3 and E(x²) = 2

The boy is 630 meters south from his starting point.

We must take into account the southward component of his shift.

We can imagine a right-angled triangle where the hypotenuse represents the boy's total displacement of 1260 meters, the angle between the hypotenuse and the south direction is 120°, and the side next to the angle represents the southward displacement given that the boy walks 1260 meters on a bearing of 120°.

We can use trigonometric functions to calculate the displacement to the south. Since the adjacent side and hypotenuse of a right triangle are connected in this instance, we will use the cosine function.

cos(120°) = adjacent / hypotenuse

cos(120°) = adjacent / 1260

Solving for the adjacent side (southward displacement):

adjacent = cos(120°) * 1260

adjacent = (-0.5) * 1260

adjacent = -630

The negative sign indicates that the southward displacement is in the opposite direction or "south" relative to the starting point.

Therefore, the boy is 630 meters south from his starting point.
