The angles in the triangle are as follows:

m∠S = m∠Q = 58°

m∠T = 64°

The unknown angles in the triangle can be found as follows:

In the triangle STQ, ST = TQ and SD is perpendicular to TQ.

Therefore, let's find the unknown angles as follows:

Hence, base on ST = TQ, STQ is an isosceles triangle. Therefore,

m∠S = m∠Q

Therefore,

m∠Q = 180 - 90 - 32

m∠Q = 58 degrees

m∠S = m∠Q = 58 degrees

Finally,

m∠T = 180 - 58 - 58

m∠T = 64 degrees

Using the given information, the measure of each exterior angle in the polygon is 20°

From the question, we are to determine the measure of each exterior angle in the polygon

Let the number of sides in the polygon be n.

Sum of exterior angles in a polygon = 360°

Thus,

Measure of one exterior angle = 360°/n

From the given information,

The measure of each exterior angle is 12.5% of the measure of each interior angle

The measure of each interior angle = (n - 2)180° / n

Thus,

360°/n = 12.5% of (n - 2)180° / n

360° = 12.5% of (n - 2)180°

Solve for n

360° = 0.125 × (n - 2)180°

360° =  (n - 2)22.5°

360° = 22.5n° - 45°

22.5n° = 360° + 45°

22.5n° = 405°

n = 405°/22.5°

n = 18

Then,

Measure of each exterior angle = 360° / 18

Measure of each exterior angle = 20°

Hence, the measure of each exterior angle is 20°

Answer:

(C) 297

Step-by-step explanation:

Write a proportion. 45 miles is to 5 gallons as x miles is to 33 gallons.

45 / 5 = x / 33

9 = x / 33

x = 297

We can use the distance formula to find the distances between the fire hydrants and determine whether they form a right triangle. The value of y is 4.

The distance between (0,0) and (2,5) is:

√((2-0)² + (5-0)²) = √29

The distance between (0,0) and (7,y) is:

√((7-0)² + (y-0)²) = √(49 + y²)

The distance between (2,5) and (7,y) is:

√((7-2)² + (y-5)²) = √(25 + (y-5)²)

If these distances form a right triangle, then the Pythagorean theorem must be satisfied:

(√29)² + (√(49 + y²))² = (√(25 + (y-5)²))²

Simplifying this expression, we get:

29 + 49 + y² = 25 + (y-5)²

Expanding the square on the right-hand side, we get:

29 + 49 + y² = 25 + y² - 10y + 25

Simplifying this expression, we get:

y = 4

Population proportion (claim): p = 0.85

Sample proportion: [tex]\hat p[/tex]= 19/25

What is proportion?

In statistics, proportion typically refers to the proportion or percentage of individuals or items in a population that have a specific characteristic or belong to a certain category.

In this scenario, the population proportion refers to the proportion of all Prime members' packages that arrive within two business days. The claim made by Amazon is that this population proportion is 85%.

Let's denote the population proportion as p.

a. The population proportion:

p = 0.85

The sample proportion, on the other hand, refers to the proportion of packages that arrived within two business days among the 25 students in the random sample. We can calculate the sample proportion using the number of students who claimed their packages arrived within two business days.

Let's denote the sample proportion as [tex]\hat p[/tex] (pronounced "p-hat").

Given:

Number of students in the sample (n) = 25

Number of students who claimed their packages arrived within two business days (x) = 19

b. The sample proportion:

[tex]\hat p[/tex] = x / n

[tex]\hat p[/tex] = 19 / 25

Therefore, the sample proportion is 19/25.

To summarize:

P(A AND B) is approximately 0.101 (rounded to three decimal places).

Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome. Conditional probability is calculated by multiplying the probability of the preceding event by the updated probability of the succeeding, or conditional, event.

To find P(A AND B), we can use the conditional probability formula:

P(A AND B) = P(A|B) * P(B)

Given:

P(A|B) = 0.22

P(B) = 0.46

10 liters of water was drained out of the tank in one minute and it would take 80 minutes to completely drain the water

This is the slope of the graph

From the graph, we have

(x, y) = (0, 800) and (40, 400)

So, we have

Slope = (400 - 800)/(40 - 0)

Evaluate

Slope = -10

This means that 10 liters of water was drained out of the tank in one minute

From (a), the equation of the line would be

y = -10x + 800

When the water is completely out, we have

-10x + 800 = 0

So, we have

x = 80

The factor that -8 - 7i should be multiplied by to find the quotient is 1 + 2i and the quotient is (-22 - 23i) / 5.

When dividing complex numbers of the form a + bi by another complex number of the form c + di, we use the following method:

Multiplying both the numerator and denominator by the conjugate of the denominator, c - di, we get:

(a + bi)(c - di)/(c + di)(c - di) = [(ac + bd) + (bc - ad)i]/(c² + d²)

where a, b, c, and d are real numbers and i is the imaginary unit with the property i² = -1.

In the given question, the denominator is 1 - 2i, so its complex conjugate would be 1 + 2i. Therefore, we need to multiply -8 - 7i by 1 + 2i in both numerator and denominator to get the quotient: (-8 - 7i)(1 + 2i) / (1 - 2i)(1 + 2i) = (-8 - 23i - 14) / (1 + 4) = (-22 - 23i) / 5

To express the average monthly U.S. gas consumption during the part of the year between the beginning of April and the end of September, we can set up an integral to calculate the average value of a function over a specific interval.

Let's denote the gas consumption as a function of time, G(t), where t represents the months from April to September. We'll integrate this function over the interval [April, September] to find the average gas consumption.

The integral that represents the average monthly U.S. gas consumption is:

(1 / (September - April)) ∫[April, September] G(t) dt

The type of correlation that occurs when two variables are statistically correlated due to the influence of a third variable is called a spurious correlation.

A spurious correlation is a type of correlation that occurs when two variables are statistically related to each other, but the relationship is not causal. Instead, the relationship is driven by the influence of a third variable that is related to both variables. This type of correlation can be misleading and can lead to incorrect conclusions if not properly understood.

For example, consider the relationship between ice cream sales and violent crime. Studies have found a positive correlation between these two variables, meaning that as ice cream sales increase, so do violent crimes. However, it is unlikely that there is a causal relationship between these two variables. Instead, the real cause of the correlation is likely the temperature. As the temperature increases, people are more likely to buy ice cream and to be out and about, which increases the opportunity for violent crime to occur. Thus, the temperature is the third variable that is driving the spurious correlation between ice cream sales and violent crime.

It is a type of correlation where there is no causal relationship between the two variables that are correlated. Instead, the correlation is driven by the influence of a third variable that is related to both variables.
