The equation of the first circle is (x + 2)² + (y - 4)² = 16, and the equation of the second circle is x² + y² = 64.

What is equation of circle?

The equation of a circle is a mathematical representation of the geometric shape of a circle. It defines the relationship between the coordinates of the points on the circle and the center of the circle. There are different forms of the equation of a circle, but the most commonly used form is the standard form, which is:

(x - a)² + (y - b)² = r²

Where (a, b) are the coordinates of the center of the circle, and r is the radius of the circle.

The equation can be written in different forms depending on the information given. For example, if the center of the circle is at the origin (0,0), then the equation becomes x² + y² = r²

Here,

Centre of first circle is (-2,4) and radius is 4 unit and centre of second circle is (0,0) and radius is 8 unit.

We can write the equations of the two circles as follows:

First Circle:

Center: (-2, 4)

Radius: 4 units

So, required equation of first circle is (x + 2)² + (y - 4)² = 16

Second Circle:

Center: (0, 0)

Radius: 8 units

So, required equation of second circle is x² + y² = 64

Thus, the equation of the first circle is (x + 2)² + (y - 4)² = 16, and the equation of the second circle is x² + y² = 64.

Therefore, P(A|BC) = 4/7.

a. P(A|B)

We can use Bayes' theorem to calculate P(A|B):

P(A|B) = P(A ∩ B) / P(B)

We are given that P(A ∩ B) = 0.2 and P(B) = 0.3, so:

P(A|B) = 0.2 / 0.3 = 2/3

Therefore, P(A|B) = 2/3.

b. P(AC ∩ BC)

Using the complement rule, we can rewrite AC ∩ BC as (A ∪ B)C:

AC ∩ BC = (A ∪ B)C

Using De Morgan's laws, we can further rewrite this as:

AC ∩ BC = A'C ∩ B'C

Now, we can use the distributive property to write:

A'C ∩ B'C = (A ∪ B)'

Using the complement rule again, we have:

A'C ∩ B'C = 1 - P(A ∪ B)

We can use the inclusion-exclusion principle to calculate P(A ∪ B):

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

We are given that P(A) = 0.6, P(B) = 0.3, and P(A ∩ B) = 0.2, so:

P(A ∪ B) = 0.6 + 0.3 - 0.2 = 0.7

Therefore:

A'C ∩ B'C = 1 - 0.7 = 0.3

Hence, P(AC ∩ BC) = 0.3.

c. P(A ∩ BC)

Using the complement rule, we can write BC as 1 - B:

A ∩ BC = A ∩ (1 - B)

We can distribute the intersection over the complement:

A ∩ BC = A - (A ∩ B)

We are given that P(A) = 0.6 and P(A ∩ B) = 0.2, so:

A ∩ BC = 0.6 - 0.2 = 0.4

Therefore, P(A ∩ BC) = 0.4.

d. P(A|BC)

We can use Bayes' theorem again to calculate P(A|BC):

P(A|BC) = P(A ∩ BC) / P(BC)

Using the complement rule, we can write BC as 1 - B:

P(A|BC) = P(A ∩ (1 - B)) / P(1 - B)

We can distribute the intersection over the complement:

P(A|BC) = P(A) - P(A ∩ B) / P(1 - B)

We are given that P(A) = 0.6, P(A ∩ B) = 0.2, and P(B) = 0.3, so:

P(A|BC) = 0.6 - 0.2 / (1 - 0.3) = 0.4 / 0.7

Therefore, P(A|BC) = 4/7.

Answer:

Step-by-step explanation:

a. -3 < x <= 4

x = -2, -1, 0, 1, 2, 3, 4.

b. -3 < x < 4

x = -2, -1, 0, 1, 2, 3.

The probability that 4 women have a mean weight below 108 lb is approximately 0.008.

The probability that 58 women have a mean weight below 108 lb is zero.

The probability is determined using the central limit theorem.

(b) If 4 women are randomly selected, the sample mean weight (x) will also be normally distributed:

mean = 143 lb

standard deviation = 29/√(4)

standard deviation = 14.5 lb.

We can use the z-score formula to find the probability that the sample mean weight is below 108 lb:

z = (108 - 143) / 14.5

z = -2.41

Using a standard normal distribution table or calculator, the probability of z being less than -2.41 is approximately 0.008.

(c) If 58 women are randomly selected, the sample mean weight (x) will also be normally distributed:

mean = 143 lb

standard deviation = 29/√(58)

standard deviation = 3.81 lb

We can use the z-score formula to find the probability that the sample mean weight is below 108 lb:

z = (108 - 143) / 3.81 ≈ -9.21

Using a standard normal distribution table or calculator, the probability of z being less than -9.21 is extremely small, practically zero.

The measures of the angles are m∠1 = 74° and m∠2 = 74°.

Given,

[tex]m\angle1 = 2x^\circ[/tex]

[tex]m\angle2 = (x + 69)^\circ[/tex]

We need to find the measure of these angles.

The straight line angle is 180 degrees.

If the angle is split the sum must be equal to 180 degrees.

We have,

[tex]m\angle1 = 2x^\circ[/tex]

[tex]m\angle2 = (x + 69)^\circ[/tex]

The figure is at a straight-line angle.

So we have,

[tex]m\angle1 + m\angle2 = 180^\circ[/tex]

[tex]2x^\circ + (x + 69)^\circ = 180[/tex]

[tex]2x + x + 69 = 180[/tex]

[tex]3x + 69 = 180[/tex]

[tex]3x = 180 - 69[/tex]

Alpha value of 0.80 would cause exponential smoothing to respond the most slowly to forecast errors.

What is exponential smoothing?

Exponential smoothing is a method for estimating time series data in statistics. This method of forecasting is widely used in the estimation of the business cycle and other data with a linear trend. Exponential smoothing predicts the next time period by combining the most recent value of the series with a fraction of the prior forecast. The quantity of smoothing is determined by the alpha parameter.

Exponential smoothing can be described as follows:

[tex]$$S_t=\alpha y_t + (1-\alpha)S_{t-1}$$[/tex]

Where

S_t is the predicted value for time t,

α is the smoothing constanty is the actual value for time t−1

(1−α)S_{t−1} is the forecasted value for time t−1

Based on the equation, it is evident that the larger the value of α, the greater the contribution of the current period to the forecast. In the same way, the lower the value of α, the less significant the role of the current period in the forecast. As a result, it can be concluded that the smaller the value of α, the more slowly exponential smoothing reacts to forecast errors.

Therefore, the answer to this question is alpha value of 0.80 would cause exponential smoothing to respond the most slowly to forecast errors.

b) Daniel can fit all the cards on one page in his binder since his binder page can hold up to 30 cards and he has a total of 70 cards after receiving [tex]\frac{1}{3}[/tex] of Sienna's cards.

a) Sienna's page was [tex]\frac{6}{9}[/tex] full, which can be simplified to [tex]\frac{2}{3}[/tex]. We know that she gave [tex]\frac{1}{3}[/tex] of her cards to Daniel, so the fraction of cards she has left is:

The area of this triangle was 18 square units.

Let's use the given information to set up some equations. We are told that the sum of the lengths of the three sides of the triangle is 18. Let's call the lengths of the two shorter sides a and b, and the length of the hypotenuse c. Then, we have a + b + c = 18.

We are also told that the sum of the squares of the lengths of the three sides is 128. Using the Pythagorean theorem, we know that a² + b² = c². So, we can rewrite this equation as a² + b² + c² = 128.

Now we have two equations with three variables. We need to find a way to eliminate one of the variables. We can do this by using the first equation to solve for one of the variables in terms of the other two. Let's solve for c:

c = 18 - a - b

Now we can substitute this expression for c into the second equation:

a² + b² + (18 - a - b)² = 128

Expanding and simplifying, we get:

2a² + 2b² - 36a - 36b + 144 = 0

Dividing by 2, we get:

a² + b² - 18a - 18b + 72 = 0

We can rewrite this equation as:

(a² - 18a + 81) + (b² - 18b + 81) = 38

Completing the square, we get:

(a - 9)² + (b - 9)² = 5

So we have:

(a - 9)² = 1

(b - 9)² = 1

This gives us four possible solutions:

a = 8, b = 10, c = 18 - a - b = 0 (not possible)

a = 10, b = 8, c = 18 - a - b = 0 (not possible)

a = 9, b = 9, c = 0 (not possible)

a = b = c = 6√2

The only valid solution is the last one, where all three sides have the same length of 6√2. To find the area of the triangle, we can use the formula:

Area = (base x height)/2

Since this is a right triangle, one of the sides is the base and the other is the height. So we can choose any two sides to use as the base and height. Let's choose a and b:

Area = (a x b)/2

Substituting the values a = 6√2 and b = 6√2, we get:

Area = (6√2 x 6√2)/2

Area = 36/2

Area = 18

Therefore, the area of the right triangle with sides of length 6√2 is 18 square units.

(Q). If y varies directly as x, and y=25 when x=5, find y when x=(-3).

Answer:

Step-by-step explanation:

the sum of the internal angles in any triangle is 180°, we have a 60° angle and a right angle (90°). We remove the known angles (90° and 60°) from 180° and we have 30° which is the value of the unknown angle (L).

Angle L = 180 - 90 - 60 =

30°

The points that are part of the solution set are (3, 7), (8, 1), and (10, 2).

The coordinate plane is a two-dimensional space formed by two perpendicular lines called the x-axis and y-axis. The point where the two axes intersect is called the origin. Each point in the plane is identified by a pair of numbers called its coordinates, where the first number represents its position along the x-axis and the second number represents its position along the y-axis. Coordinates are typically written as (x, y), with the x-coordinate listed first and the y-coordinate listed second. The coordinate plane is commonly used in mathematics to graph and analyze equations, functions, and geometric shapes.

Let x be the number of bags of popcorn and y be the number of bags of cotton candy. Then the cost constraint is:

3x + 7y ≤ 56

We also have the constraint that Chris needs at least 7 bags of popcorn:

x ≥ 7

To graph these constraints, we can rewrite them in slope-intercept form:

y ≤ (-3/7)x + 8

x ≥ 7

The first inequality has a slope of -3/7 and a y-intercept of 8, and the second inequality is a vertical line at x = 7.

To plot the points that are part of the solution set, we can simply plug them into the two inequalities and see if they are true. The points that satisfy both inequalities are part of the solution set.

(3, 7) satisfies both inequalities:

7 ≤ (-3/7)(3) + 8

3 ≥ 7

(2, 2) does not satisfy the first inequality:

2(7) > 3(2) + 7

(8, 1) satisfies both inequalities:

1 ≤ (-3/7)(8) + 8

8 ≥ 7

(10, 2) satisfies both inequalities:

2 ≤ (-3/7)(10) + 8

10 ≥ 7

(5, 5) does not satisfy the first inequality:

5(7) > 3(5) + 7

Therefore, the points that are part of the solution set are (3, 7), (8, 1), and (10, 2).

To find the measure of angle QZX, we need to use the fact that the sum of the angles in a triangle is 180 degrees.

First, we can find the measure of angle ZWQ:

Angle WZQ + Angle WZX = 180 degrees

92 degrees + 63 degrees = 155 degrees

Therefore, angle ZWQ has a measure of 155 degrees.

Now, we can find the measure of angle QZX:

Angle ZWQ + Angle QZX = 180 degrees

155 degrees + Angle QZX = 180 degrees

Subtracting 155 from both sides, we get:

Angle QZX = 25 degrees

Therefore, the measure of angle QZX is 25 degrees.
