When the cosine of an angle (0) is 3/5 and the angle lies in quadrant 4, the exact value of the sine of that angle is -4/5.

To find the exact value of sin(0), we can utilize the Pythagorean identity, which states that \(sin^2(x) + cos^2(x) = 1,\) where x is an angle in a right triangle. Since the terminal side of the angle (0) is in quadrant 4, we know that the cosine value will be positive, and the sine value will be negative.

Given that cos(0) = 3/5, we can determine the value of sin(0) using the Pythagorean identity as follows:

\(sin^2(0) + cos^2(0) = 1\\sin^2(0) + (3/5)^2 = 1\\sin^2(0) + 9/25 = 1\\sin^2(0) = 1 - 9/25\\sin^2(0) = 25/25 - 9/25\\sin^2(0) = 16/25\)

Taking the square root of both sides to find sin(0), we have:

sin(0) = ±√(16/25)

Since the terminal side of (0) is in quadrant 4, the y-coordinate, which represents sin(0), will be negative. Therefore, we can conclude:

sin(0) = -√(16/25)

Simplifying further, we get:

sin(0) = -4/5

Hence, the exact value of sin(0) when cos(0) = 3/5 and the terminal side of (0) is in quadrant 4 is -4/5.

The total radius of a cone with a radius of 4in and a height of 12in is 8in.

The total radius of a cone is the sum of the radius of the base and the slant height of the cone. The slant height of a cone can be found using the Pythagorean theorem, which states that the square of the slant height is equal to the sum of the square of the height and the square of the radius of the base.

So, to find the total radius of the cone, we need to calculate the slant height and add it to the radius of the base.

Slant height = sqrt(radius² + height²)

= √(4² + 12²)

= √(160)

= 12.65in (rounded to two decimal places)

Total radius = radius + slant height

= 4in + 12.65in

= 16.65in

≈ 8in (rounded to two decimal places)

Therefore, the total radius of the cone is approximately 8 inches.

a) 55 people expect to be between 165 and 175 cm.

b) 76 people to be taller than 166 cm.

What is Standard normal distribution?

The standard normal distribution is a special type of normal distribution where the mean is 0, and the standard deviation is 1.

a) To answer this question, we can use the standard normal distribution table to find the proportion of heights that fall within certain ranges of the mean.

The standard normal distribution table gives us the proportion of values within a certain number of standard deviations of the mean.

Since the standard deviation of the heights is 5, we can find the proportion of heights between 165 and 175 cm by looking at the range of values that are one standard deviation below and one standard deviation above the mean.

The mean of the heights is 170, so one standard deviation below the mean is 170 - 5 = 165. One standard deviation above the mean is 170 + 5 = 175. Therefore, the range of heights that are one standard deviation below and one standard deviation above the mean is 165 to 175.

If we look at the standard normal distribution table, we find that approximately 68% of the values fall within one standard deviation of the mean. Since 80 is approximately 68% of 118, we would expect approximately 55 people to have heights between 165 and 175 cm.

Hence, 55 people expect to be between 165 and 175 cm.

b) For the second part of the question, we can find the proportion of heights that are taller than 166 cm by looking at the range of values that are more than one standard deviation above the mean.

The mean of the heights is 170, so more than one standard deviation above the mean is anything greater than 175. If we look at the standard normal distribution table, we find that approximately 95% of the values fall within two standard deviations of the mean.

Since 80 is approximately 95% of 84, we would expect approximately 76 people to be taller than 166 cm.

Hence, 76 people to be taller than 166 cm.

Step-by-step explanation:

According to the theory of comparative advantage, if the United States and Mexico increase their trade with each other, the two countries will experience an increase in their standards of living.

The theory of comparative advantage suggests that countries can benefit from specializing in the production of goods and services in which they have a lower opportunity cost compared to other countries. By focusing on producing what they are relatively more efficient at, countries can achieve higher levels of productivity and output.

When countries engage in international trade based on comparative advantage, they can access a wider range of goods and services at lower costs. This leads to increased efficiency, greater market competition, and access to a larger consumer base. As a result, both the United States and Mexico can enjoy the advantages of trade, such as lower prices, increased variety, and access to new markets.

By leveraging their respective comparative advantages and engaging in trade, the United States and Mexico can enhance their productivity, economic growth, and overall standards of living. The specialization and exchange of goods and services allow countries to allocate resources more efficiently, leading to higher living standards for their populations.

The probability of drawing a blue marble can be found by dividing the number of blue marbles by the total number of marbles:

P(drawing a blue marble) = 2/12 = 1/6

The complement of an event is the probability of the event not occurring, which can be found by subtracting the probability of the event from 1:

P(not drawing a blue marble) = 1 - P(drawing a blue marble)

P(not drawing a blue marble) = 1 - 1/6

P(not drawing a blue marble) = 5/6

So, the best answer for the complement to the probability that Alison will draw a blue marble is 5/6

Step-by-step explanation:

Step 1: Find the probability of drawing a blue marble.

To find the probability of drawing a blue marble, we need to divide the number of blue marbles by the total number of marbles in the sack.

Number of blue marbles = 2

Total number of marbles = 2 + 4 + 5 + 1 = 12

So, the probability of drawing a blue marble is:

P(drawing a blue marble) = 2/12

Step 2: Find the complement of the probability of drawing a blue marble.

The complement of an event is the probability of the event not occurring. We can find the complement of the probability of drawing a blue marble by subtracting it from 1.

P(not drawing a blue marble) = 1 - P(drawing a blue marble)

P(not drawing a blue marble) = 1 - 2/12

Simplify the fraction by finding the common factor of the numerator and denominator:

P(not drawing a blue marble) = 1 - 1/6

Then, we need to get the common denominator:

P(not drawing a blue marble) = 6/6 - 1/6

Simplify the expression:

P(not drawing a blue marble) = 5/6

So, the best answer for the complement of the probability that Alison will draw a blue marble is 5/6.

Answer:

  A.  -5

Step-by-step explanation:

You want the slope of a graphed line that crosses grid points (0, 2) and (1, -3).

The sign of the slope is positive if the line goes up to the right. This line goes down to the right, so the sign of its slope is negative. (Eliminates choices C and D)

The magnitude of the slope is the ratio of vertical distance to horizontal distance between two points. This line drops 5 vertical squares for each square to the right, so its slope is ...

  rise/run = -5/1 = -5

The slope is best represented by -5.

__

Additional comment

From a point on the line that is a crossing of grid lines, if the line crosses the next vertical grid line before it crosses the next horizontal grid line, the magnitude of its slope is less than 1.

Here, the line crosses several horizontal grid lines before it crosses another vertical grid line, so its slope has a magnitude greater than 1. When the choice is between -5 and -1/5, the larger magnitude number is -5.

From two points on the line, you can find the slope using the formula ...

  m = (y2 -y1)/(x2 -x1)

  m = (-3 -2)/(1 -0) = -5/1 = -5 . . . . . . using points (0, 2) and (1, -3)

Case 1 :

Radius, r = 5 feet.

Area,

\(A=\pi r^2\\\\A = 3.14\times 5^2\ feet^2\\\\A = 78.5\ feet^2\)

Case 2 :

Diameter, d = 56 mm.

So, radius, r = d/2 = 28 mm.

Area,

\(A = 3.14\times 28^2\ mm^2\\\\A = 2461.76\ mm^2\)

Hence, this is the required solution.

By applying total cost concept, it can be concluded that the expression represents the total cost is 1.45d (option A).
