After solving for angles, the value of p in the given angles is 44°.

An angle is formed when two straight lines or rays meet at a single terminal.

The place where two points converge is known as an angle's vertex.

The name "angel" comes from the Latin word "angulus," which means "corner."

Angles are also produced when two planes intersect.

These are what are known as dihedral angles.

So, we know that ∠CAD = 90°.

And since ∠CAB is s straight angle. Then,

∠CAD + ∠DAB = 180

90 + p + 46 = 180

p + 136 = 180

p = 180 - 136

p = 44°

Therefore, after solving for angles, the value of p in the given angles is 44°.

Given the information in the inquiry;

Test size n = 500

x = 361

p₀ = 77% = 0.77

q₀ = 1 - p₀ = 1 - 0.77 = 0.23

The dimensions of the rectangular field is 15 meters long and 14 meters wide.

A rectangle is a two-dimensional figure that has 2 pair of parallel sides that are of the same length. The corners made by these sides are right triangles.

Let x = length of the rectangular field

y = width of the rectangular field

If the area of the land is 210 square meters, then the product of its length and width is equal to 210 square meters.

A = l x w

210 = xy

x = 210/y

Serenity has 58 m of fencing for the perimeter of the rectangular field.. Hence,

P = 2l + 2w

58 = 2x + 2y

Substitute the expression of x and solve for y.

58 = 2x + 2y

58 = 2(210/y) + 2y

58 = 420/y + 2y

Multiply both sides by y and divide by 2.

29y = 210 + y²

y² - 29y + 210 = 0

(y - 14)(y - 15) = 0

y = 14 ; y = 15

Hence, y = 14.

Substitute the value of y and solve for x.

x = 210/y

x = 210/14

When two lines come together at a common point, an angle is created. They are expressed as a number of degrees, denoted by the symbol °. Acute, right, obtuse, and reflex angles are the other three significant types of angles.

Given that ∠ADB and ∠BDC are supplementary angle.

∠ADB = (2x - 15)° and ∠BDC = 11x°.

Two angles are supplementary angle, if their sum is equal to 180°.

Therefore,

∠ADB + ∠BDC = 180°

Putting the value of ∠ADB and ∠BDC:

(2x - 15)° + 11x° = 180°

2x - 15 + 11x = 180

Combine like terms:

(2x + 11x) -15 =180

13x - 15 =180

Add 15 with both sides:

13x = 180 +15

13x = 195

The answer is true. The curve of t-distribution has thicker tails than the curve of the standard normal distribution.

The t-distribution is also called as Student's t-distribution which is a type of probability distribution with a bell shape which is similar to  normal distribution but has thicker tails. It is used to estimate population parameters when sample sizes are small or variances are unknown. T-distributions have a higher probability of extreme values more than normal distributions which results in thicker tails.

Tail thickness is determined by a t-distribution parameter called degrees of freedom, with lower values resulting in heavier tails and higher values resulting in the t-distribution resembles standard normal distribution with a  standard deviation of 1and mean of 0.

Thus, t-distribution has thicker tails than the normal distribution.

C: Those who like Hamburgers but not burritos.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

                         Like Hamburgers ↓  Does Not Like Hamburgers↓    Total↓

Likes burritos →                 39                           38                                   77

Does not like burritos →    95                           33                                 128

Total →                                134                           71                                 205

So, according to the above table, a total of 77 customers like burritos, out of which 38 do not like hamburgers, hence, the remaining 77-38= 39 like Hamburgers.

A total of 128 customers do not like burritos, out of which 95 do like hamburgers, hence, the remaining  128 - 95 = 33 do not like Hamburgers.

A total of 134 customers like hamburgers, but 71 do not like it, hence, the total respondents are 205.

Part A: The percent of respondents who do not like hamburgers and burritos both

There are 33 such respondents.  

Hence, percentage = (033/205) *100 = 16.09 %

Part B: Marginal relative frequency of all customers that like hamburgers

It will be the ratio of the sum of the customers that like hamburgers to the total number of respondents

Hence, ratio  134/205 = 0.65

Part C: The data point that has the strongest association of its two factors.

For this, we need to find the ratio of all the four data with the total.

Those who like Hamburgers and burritos = 39/134 = 0.29

Those who like Hamburgers but not burritos = 95/134 = 0.71

Those who like burritos but not Hamburgers = 38/71 = 0.53

Those who do not like burritos or Hamburgers = 33/71 = 0.47

Answer:

Step-by-step explanation:

The function f, in the slope-intercept form is f= -3x+6.

The slope or gradient of the line is a numerical value used to describe a line's steepness and direction in mathematics. It was first used to describe slope in O'Brien's (1844) and Todhunter's (1888) versions of the equation for a straight line, which are both written as "y = mx + b" and "y = mx + c," respectively. The choice of the letter m for slope has no apparent justification.

Calculating slope involves comparing the "vertical change" to the "horizontal change" between any two points on a line, or any two points. The ratio, which provides the same number for each, is occasionally given as a quotient ("rise over run").

Here given,

For a linear function f,

f(2)=0 and f(4)=-6

So, from the given hint the points are (2, 0) and (4, -6)

Here slope m=(-6-0)/(4-2)

m=-6/2

m= -3

We know that the equation of the function in slope-intercept form is:

f=mx +c

By substituting the point (2, 0) and m= -3 in the function we get,

0= -3(2)+c

c=6

Now, by substituting m= -3 and c=6 in the function, we get

T = 428.5

B = 5

A = 428.5 / 5

A = 85.7 ounces

The location of B under the Line Segment Partition is 6.8

What is Line Segment Partition?

A line segment is partitioned when it is divided into equal parts according to a specified ratio. The total number of partitions of the line segment must be equal to the sum of the two values in the ratio.

Given in the question that on a number line AC;

Location of Point A = 4

Location of point C = 11

point B lies between points A and C

So, B divides line AC in the ratio AB: BC = 2:3.

Thus;

BC = 3/5 of the total length of the AC

AB = 2/5 the total length of the AC

Then, total length of AC = 11-4 = 7

BC = 3/5 * 7 = 4.2

AB = 2/5 * 7 = 2.8

Thus, the location of point B is; 4 + 2.8 = 6.8
