Step-by-step explanation:

To find the measure of an angle formed by a secant and a tangent that intersect outside a circle, follow the rule that the measure of the angle is equal to half the difference of the intercepted arcs.

When a secant and a tangent intersect outside a circle, they form an angle. This angle can be found by utilizing the intercepted arcs formed by the secant and the tangent.

To determine the measure of the angle, follow these steps:

Identify the two intercepted arcs: The secant intersects the circle at two points, creating two intercepted arcs. One of these arcs will be larger than the other. The tangent intersects the circle at one point and creates an intercepted arc.

Find the difference between the intercepted arcs: Subtract the measure of the smaller intercepted arc from the measure of the larger intercepted arc.

Divide the difference by 2: Take half of the difference obtained in the previous step to find the measure of the angle formed by the secant and the tangent.

By following this approach, you can determine the measure of an angle formed by a secant and a tangent that intersect outside a circle based on the difference between the intercepted arcs. Remember to consider the larger and smaller intercepted arcs and divide the difference by 2 to find the angle's measure.

a.

coordinates of A are (2,4)

b.

coordinates of B are (6,0)

i.

(4,2) is the midpoint

ii.

y = -3x + 18 is the parallel line

Step-by-step explanation:

a.

if two things are equal to the same thing then they are equal to each other

y = 4

2x + y = 8 is y = -2x +8 so

-2x +8 = 4

-2x = -4

x = 2

coordinates of A are (2,4)

b.

if two things are equal to the same thing then they are equal to each other

y=0

3x+y=18 is y = -3x+18 so

-3x+18=0

x = 6

coordinates of B are (6,0)

midpoint formula is

(X1+X2)/2 , (Y1+Y2)/2

(2,4) (6,0)

(X1+X2)/2 , (Y1+Y2)/2

(2+6)/2 , (4+0)/2

(4,2) is the midpoint

parallel line has the same x value

so for a line parallel to 3x+y=18 or y = -3x+18

the parallel line would be

y = -3x

point slope formula

point slope formulay - y1 = m (x - x1)

3x+y=18 or y = -3x+18 was 6,0 at y = 0

y - y1 = m (x - x1)

y - 0 = m (x - x1)

since it's a parallel line the m has to be the same

(6,0)

y - 0 = -3 (x - 6)

y = -3x + 18 is the parallel line

Answer:

The average rate of change of the function f(x) = -2x + 15 from x1 = 0 to x2 = 3 is -2.

Step-by-step explanation:

To obtain the average rate of change of a function from x1 to x2, you can use the formula:

Average Rate of Change = (f(x2) - f(x1)) / (x2 - x1)

In this case, you are given the function f(x) = -2x + 15, and the values x1 = 0 and x2 = 3.

First, calculate the values of f(x1) and f(x2) by substituting x1 and x2 into the function:

f(x1) = -2(0) + 15 = 15

f(x2) = -2(3) + 15 = 9

Now we can substitute these values into the formula for average rate of change:

Average Rate of Change = (f(x2) - f(x1)) / (x2 - x1)

= (9 - 15) / (3 - 0)

= -6 / 3

= -2

Therefore, the average rate of change of the function f(x) = -2x + 15 from x1 = 0 to x2 = 3 is -2.

The probability that Sue will sit next to Bob is 96/24 = 4. So, the odds are 4:1.

We need to find out the odds that Sue will sit next to Bob. There is a round table with five different people. Therefore, the total number of ways that five different people can be seated at a round table is (5 - 1)! = 4!.

Thus, there are 24 ways that these five different people can be seated around the table. Now, let's say Sue and Bob are sitting next to each other. Thus, there are 4! = 24 ways in which they can be seated around the table. Now, Sue and Bob can be treated as a single unit since they are sitting together. So, there are a total of 48 + 48 = 96 possible ways that Sue will sit next to Bob in a 5 person round table. There are 24 possible ways that 5 people can be seated around the table.

Since this is Equilateral Equiangular triangle each angle is going to be 60 degrees (sum of the interior angles of a triangle is 60 degrees).

Answer: y = 8

Step-by-step explanation:

Firstly, to solve this problem, we must identify what type of triangle this is.

This is an equalateral/equiangular triangle. This means that the sides are the same size and most importantly, the angles are the same degrees. How do we know this though? We know this because if a triangle is equilateral, it has equal angles. The reason we know this is an equilateral triangle is that it is denoted by the marks of congruency or the little dashes on the sides. All triangles that are equiangular have the same three angles of 60 degrees each. To top that off, 60 x 3 = 180, the number of degrees a triangle must have together for it to be considered a triangle. So how do we figure this out though?

Firstly, we must make the equation EQUAL to 60 degrees

60 = 8y - 4

Then simply solve

Add the 4 to each side, we need to do the reverse sign to get rid of it on the variable side. So it would be positive (+4)

60 + 4 = 8y

64 = 8y

Then, simply, we divide each side by 8 to get our answer!

64/8 = 8y/8

8 = y

y = 8

You can confirm by plugging the 8 into y, and you will get 60.

The probability that Dr. Naiciteid's 90% confidence interval captured the true population average is 0.90 or 90%.

A confidence interval is a range of values that is likely to contain the true population parameter. In this case, Dr. Naiciteid obtained a 90% confidence interval of (175.33, 263.74) lbs.

The confidence level of 90% means that if we were to repeat the sampling process multiple times, 90% of the intervals obtained would capture the true population average weight. In other words, there is a 90% probability that the true population average weight falls within the interval (175.33, 263.74) lbs.

Therefore, there is a 90% probability that Dr. Naiciteid's 90% confidence interval captured the true population average weight of nutrition students.

The standard error of the sample mean is 1.21.

Given;

Suppose a diet regimen for men results in an average weight loss of between 13. 4 and 18. 3 pounds, according to a 95% confidence interval. These findings were based on a group of 42 men who were classified as overweight at the beginning of the four-month trial.

A 95% confidence interval for a population mean is (13.4, 18.3)

Upper limit = 18.3

Lower limit = 13.4

Since population SD is unknown, this interval is constructed using the t distribution.

n = 42

c = 0.95

∴ α = 1 - c = 1 - 0.95 = 0.05

α/2 = 0.025

Also, d.f = n - 1 = 42 - 1 = 41

∴ ta/2.d.f =  ta/2.n-1  =  t0.025,41  =  2.02 . . . . use t table

Now,

The margin of error = (Upper limit - Lower limit)/2

                                 = (18.3 - 13.4)/2

                                 = 2.45

But,

Margin of error = ta/2.d.f-  * (s / \sqrt{} n)

Margin of error = ta/2.d.f-  * Standard error

2.45 = 2.02 * Standard error

Standard error = 1.2129

The solution to the equation in this problem is given as follows:

y = -4.

The equation for this problem is defined as follows:

\(\frac{y - 6}{y^2 + 3y - 4} = \frac{2}{y + 4} + \frac{7}{y - 1}\)

The right side of the equality can be simplified applying the least common factor as follows:

[2(y - 1) + 7(y + 4)]/[(y + 4)(y - 1)] = (9y + 26)/(y² + 3y - 4)

The denominators of the two sides of the equality are equal, hence the solution to the equation can be obtained equaling the numerators as follows:

9y + 26 = y - 6

Answer:

1 over 7

Step-by-step explanation:

To find the probability that the first pencil is red and the second pencil is blue, we need to consider the number of ways in which this outcome can occur compared to the total number of possible outcomes.

There are 7 red pencils in the bag, and Julia picks one of them on the first draw, so there is a 1 in 7 chance of her picking a red pencil. There are 4 blue pencils in the bag, and Julia picks one of them on the second draw, so there is a 1 in 4 chance of her picking a blue pencil.

Since the probability of each event is independent of the other, we can multiply the probability of each event to find the probability of both events occurring.

Therefore, the probability that the first pencil is red and the second pencil is blue is:

(1 in 7) * (1 in 4) = 1/7 * 1/4 = 1/28

The probability that the first pencil is red and the second pencil is blue is 1/28, which is equivalent to choice A: 1 over 7. The other choices are not equivalent to this probability.

Answer:

1/7

Step-by-step explanation:

If there are 14 pencils and 7 are red then the equation would be 14-7 which is 7.

Answer: m = -7; r = 4; y = -6

Step-by-step explanation:

1/9 (2m - 16) = 1/3 (2m + 4)

2/9m - 16/9 = 2/3m + 4/3

Bring like terms together

Subtract 2/3m from both sides

2/9m - 2/3m - 16/9 = 4/3

Add 16/9 to both sides

2/9m - 2/3m = 4/3 + 16/9

Find the LCM (Least Common Multiple) of 3m and 9m

3m = 3m, 6m, 9m, 12m...

9m = 9m, 18m..

LCM = 9m

Multiply 3 to the denominator and nominator of 2/3m so the denominator can be 9.

2/3 × 3/3 = 6/9

Also find the LCM (Least Common Multiple) of 3 and 9

3 = 3, 6, 9, 12...

9 = 9, 18..

LCM = 9

Multiply 3 to the denominator and nominator of 4/3 so the denominator can be 9.

4/3 × 3/3 = 12/9

Now the equation looks like this..

2/9m - 6/9m = 12/9 + 16/9

Combine like terms

-4/9m = 28/9

Multiply -9/4 in both sides

m = -7

-4(r + 2) = 4(2 - 2r)

Distribute in both sides

-4r - 8 = 8 - 8r

Add 8r to both sides

-4r + 8r - 8 = 8

Add 8 to both sides

-4r + 8r = 8 + 8

Combine like terms

4r = 16

r = 4

12 (5 + 2y) = 4y - (6 - 9y)

The equation is basically:

12 (5 + 2y) = 4y - 6 + 9y

So distribute 12..

60 + 24y = 4y - 6 + 9y

60 + 24y = 13y - 6

Subtract 13y from both sides

60 + 11y = -6

Subtract 60 from both sides

11y = -66

Divide both sides by 11

y = -6
