The measure of an exterior angle of the regular polygon shown in the figure is 60°.

The angle between a side of a polygon and an extended adjacent side is called its exterior angle.

Given is a polygon, since, it has six vertices, so we can say it is a regular hexagon,

We know that, the sum of interior angles of regular hexagon is 720°

Therefore, one interior angle = 720 / 6 = 120°

If we extend a side of the hexagon, (refer to figure attached in solution)

Then, the interior angle and an exterior angle "A" will make a linear pair,

Therefore,

120° + A = 180°

A = 60°

Hence, the measure of an exterior angle of the regular polygon shown in the figure is 60°.

When will divide (3x³+x-200) by (x-4) will get 3x²+12x+49 and -4 as remainder.

Division is the process of splitting a number or an amount into equal parts.

Given is an expression, 3x³+x-200 which is divided by x-4,

Therefore,

(3x³+x-200) / (x-4)

Divide the leading term of the dividend by the leading term of the divisor:

3x³/x = 3x²

Multiply it by the divisor: 3x²(x−4)=3x³−12x²

Subtract the dividend from the obtained result:

(3x³+x−200)−(3x³−12x2) = 12x²+x−200

Divide the leading term of the obtained remainder by the leading term of the divisor: 12x²/x = 12x

Multiply it by the divisor: 12x(x−4) = 12x²−48x

Subtract the remainder from the obtained result:

(12x²+x−200)−(12x²−48x) = 49x−200

Divide the leading term of the obtained remainder by the leading term of the divisor: 49x / x = 49

Multiply it by the divisor: 49(x−4) = 49x−196

Subtract the remainder from the obtained result:

(49x−200)−(49x−196) = −4

Hence, When will divide (3x³+x-200) by (x-4) will get 3x²+12x+49 and -4 as remainder.

Including polynomial components, such as squared or cubed predictors, is the most popular technique to fit curves to data using linear regression. Typically, the model order is determined by the number of bends required in your line. Each exponent increment causes one additional bend in the curved fitting line.

Curve of Best Fit: a scatter plot curve that best approximates the trend. If the data looks to be quadratic, we use quadratic regression to get the equation for the best-fit curve. We do a cubic regression if it looks to be cubic.

The value of N would be N = q/(9 + 4uz).

What is algebraic manipulation?

Algebraic manipulation is the process of rearranging mathematical expressions in order to solve equations or to make them easier to understand. It involves the use of mathematical operations and properties such as addition, subtraction, multiplication, division, and the commutative, associative, and distributive properties.

Given:

q - 4Nuz = 9N

To find the value of N, we can use algebraic manipulation.

The particle's displacement divided by the passage of time represents its average velocity at each time interval. The displacement of the particle for the above motion equation is given by s = 2 sint + 4 cost. By subtracting the displacement at the beginning and end of the period and dividing it by the change in time, we can determine the average velocity for each time period. As an illustration, the displacement for the time period [1,2] is 2 sin + 4 cos at the beginning of the period and 2 sin + 4 cos at the end of the period.

The area a of the window as a function of the width x of the window 12x -(4 + π)x2/8

Let y be the height of the window's rectangular part, and let P represent the window's perimeter.

P then equals x plus 2y plus the length of the semicircular part. The radius of the semicircular part is x/2.

So, P = x + 2y + (1/2)(circumference)

     P = x + 2y  + (1/2)(2)π(x/2)

     P = x + 2y +πx/2 = 24

2y = 24 - x - πx/2

y = 12 - x/2 - πx/4 = 12 - (2 + π)x/4

A = xy + (1/2)π(x/2)2

   = x(12 - (2 + π)x/4) + πx2/8

   = 12x -(2 + π)x2/4 + πx2/8

    = 12x - (4 + 2π)x2/8 + πx2/8

Let us consider 'A' represents the test indicate the presence of disease when it was actually present

A = 96%

And 'B' represents the population percent actually has the disease

B = 2%

  = 0.02

A' represents the population who represents the disease when actually disease is not present.

A' = 0.08

Probability of a person that has the disease when test also indicates its presence is given by :

P ( A/ B) = P( A∩B) / [ P(A∩B) + P(A'∩B) ]

Answer:

Shortest = 10ft

Middle = 18 ft

Longest = 26ft

Step-by-step explanation:

(btw u can make a diagram to make it easier to visualise)

Let shortest side of triangle be x

So:

1st side = 2x+6

2nd side = x

3rd side = x+8

These sides all equal to 54 ft (perimeter)

2x+6 + x + x+8 = 54

4x + 14 = 54

4x = 40

x = 10

Now that we know the shortest side just sub it back into the equations!

Answer: Based on the information provided, we can use the proportion of blue m&ms found in the sample (82 out of some larger total number of m&ms) to estimate the total number of m&ms in the entire bag.

If we let x be the total number of m&ms in the bag, we can set up the proportion:

82/x = blue m&ms / total m&ms

To solve for x, we can cross-multiply and divide by 82:

x = 82 * total m&ms / blue m&ms

x = 82 * 1

x ≈ 82

Therefore, based on the sample, we expect there to be approximately 82 m&ms in the entire bag, rounded to the nearest whole m&m.

It's worth noting that this is an estimation, and the actual number of m&ms in the bag may be different.

Number of shingles in the 6th row is 110.

An arithmetic sequence is sequence of integers with its adjacent terms differing with one common difference.

If the initial term of a sequence is 'a' and the common difference is of 'd', then we have the arithmetic sequence as:

a, a + d, a +  2d, ... , a + (n+1)d, ...

Its nth term is

T_n = a + (n-1)d

(for all positive integer values of n)

And thus, the common difference is

T_{n+1} - T_n

for all positive integer values of n

Given;

Each row has 7 fewer shingles than the row below it

First row has 75 shingles

Now,

a=75

D=7

n=6

a_{n}=a_{1}+(n-1)d

E is the midpoint of BC and D is the midpoint of AC.

Thus, applying the Midsegment Theorem, we have:

ED = 1/2(BA)

Substituting the values not expressive, we would get:

Similarly, to find the number of teachers that teach only Humanities we can subtract the number of teachers who teach both subjects from the number of teachers that teach Humanities.

To find the number of teachers who teach Humanities or science we use the elementary set formula,

Total number of teachers = 100

No of teachers who teach Humanities, n(H)= 25

No of teachers who teach Science, n(S) = 60

No of teachers who teach both Science and Humanities, n(H ∩ S) = 15  

The number of teachers who teach science but not humanities

= No of teachers who teach Science - No of teachers who teach both
