One of your friends who is self- employed starters buying, indicional heath Insurance ll years ago at a cost of $579 per quarte.

So overall, you can expect to make a profit of $166.67 if you play the game 100 times.

What is probability ?

Probability can be defined as the ratio of number of favourable outcomes and total number of outcomes.

To determine how much you expect to win or lose if you play the game 100 times, we need to calculate the expected value of each round and then multiply it by the number of rounds.

Let X be the random variable that represents the amount you win in one round of the game. The possible outcomes of X are winning $14, winning $12, or losing $10. We can calculate the expected value of X using the following formula:

E(X) = P(win $14) × $14 + P(win $12) × $12 + P(lose $10) × (-$10)

To calculate the probabilities, we can use the fact that there are 5 red balls, 3 green balls, and 4 yellow balls in the bag. The probability of drawing a red ball is therefore 5/12, the probability of drawing a green ball is 3/12, and the probability of drawing a yellow ball is 4/12.

So we have:

E(X) = (5/12) × $14 + (4/12) × $12 + (3/12) × (-$10)

E(X) = $5/3

This means that on average, you expect to win $5/3 per round. Over 100 rounds, you can expect to win:

100 × $5/3 = $166.67

However, it's important to note that this is just an average - in reality, you may win more or less than this amount depending on the luck of the draw.

Therefore, overall, you can expect to make a profit of $166.67 if you play the game 100 times.

Answer:study

Step-by-step explanation:

The cumulative frequency graph indicates that the percentage of the vehicles that go over the 30 mph speed limit is about 62.6% which more than the allowable 20%, therefore, a speed camera will have to be installed.

The cumulative frequency is the sum of the frequency up to an interval. The cumulative frequency indicates the total number of observations located above or below a value.

The cumulative frequency graph indicates the value of the sum of the number of vehicles travelling at a particular speed, therefore;

The cumulative frequency of cars traveling at 20 mph = 13

Cumulative frequency of cars traveling at 10 mph = 8

The cumulative frequency if the cars travelling at 30 mph = 50

Cumulative frequency of the cars travelling at 40 mph = 59

The cumulative frequency of the cars traveling at 50 mph = 60

Number of cars that go over the 30 mph speed limit = 59 + 60 = 119

Percentage of the cars that go over the 30 mph is therefore;

Answer:

The movie theater sold 85 large bags of popcorn and 204 small bags of popcorn.

Step-by-step explanation:

Let's use the following variables to represent the number of large and small bags of popcorn sold:

L: the number of large bags of popcorn sold

S: the number of small bags of popcorn sold

We can then write a system of equations based on the information given in the problem:

L + S = 289 (the total number of bags sold is 289)

4L + S = 544 (the total revenue from popcorn sales is $544)

To solve for L and S, we can use the method of substitution. Rearrange the first equation to solve for one variable in terms of the other:

L = 289 - S

Substitute this expression for L in the second equation and solve for S:

4(289 - S) + S = 544

1156 - 4S + S = 544

3S = 612

S = 204

Now that we know that 204 small bags of popcorn were sold, we can use the first equation to solve for L:

L + S = 289

L + 204 = 289

L = 85

Therefore, the movie theater sold 85 large bags of popcorn and 204 small bags of popcorn.

The solution is, the average speed of the boat relative to the water is 9 mph

Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).

Speed = Distance/ Time

here, we have,

Let x represent the speed of the boat.

The rate of the current was 7 mph,

Assuming the boat travelled against the current while going upstream, the total speed would be x - 7

Assuming the boat in the direction of the current while going downstream, the total speed would be x + 7

Time = speed × time

Since she travelled 32 miles upstream and 32 miles downstream, then,

Time taken to go upstream = 32/(x -7)

Time taken to go downstream = 32/(x + 7)

Since the total time of the trip was 18 hours, then

32/(x -7) + 32/(x + 7) = 18

Cross multiplying by (x - 7)(x + 7), it becomes

32(x + 7) + 32(x - 7) = 18[(x - 7)(x + 7)

32x + 224 + 32x - 224 = 18(x² + 7x - 7x - 49

32x + 32x = 18x² - 882

18x² - 64x - 882 = 0

Dividing through by 2, it becomes

9x² - 32x - 441 = 0

9x² + 49x - 81x - 441 = 0

x(9x + 49) - 9(9x + 49) = 0

x - 9 = 0 or 9x + 49 = 0

x = 9 or x = - 49/9

Since the speed of the boat cannot be negative, then x = 9

Using the Hamilton's method of apportioning of seats, the five countries will get the following number of seats:

Adams = 7

Grant =7

Colton= 11

Davis= 5

Hayes= 2

Total = 7+7+11+5+2 = 32 seats

To calculate the number of seats, first find the Standard Divisor (SD). That is: SD = Total population / Number of seats available

Total population = 213,000+225,000+351,000+158,000+70,000 = 1,017,000

Then divide the total population by number of seats available (32).

That is: SD = 1,017,000/32

SD = 31,781.25

Find the Standard Quota (SQ) for each county by using the formula;

SQ = County population / SD

Adam's SQ = 213,000/31,781.25 = 6.70

Grant's SQ = 225,000/31,781.25 = 7.08

Colton's SQ = 351,000/31,781.25 = 11.04

Davis's SQ = 158,000/31,781.25 = 4.97

Hayes's SQ = 70,000/31,781.25 = 2.20

Find the Lower Quota for each county and find the total number of occupied seats:

a. The angle generated by P in time t is pi radians.

b. The distance traveled by P along the circle in time t is 16pi cm.

c. The linear speed of P is 2pi cm/sec.

What is angular speed ?

Angular speed, also known as rotational speed, is a measure of how fast an object is rotating around a fixed point. It is typically measured in radians per second and is denoted by the symbol "ω" (omega).

Angular speed is calculated as the change in angle (measured in radians) divided by the time it takes to make that change. In other words, it is the rate at which the angle is changing over time.

Angular speed is an important concept in physics and engineering, as it is used to describe the motion of rotating objects such as wheels, gears, and turbines. It is also used to calculate other important parameters such as linear speed, centripetal force, and torque.

The problem involves finding the properties of a point P that is rotating around a circle with a given radius r and angular speed omega. The problem provides the values of r, omega, and t and asks to find the angle generated by P in time t, the distance traveled by P along the circle in time t, and the linear speed of P.

(a) To find the angle generated by P in time t, we use the formula for angular displacement:

theta = omega * t

Here, omega is given as pi/8 radians per second and t is given as 8 seconds. We substitute these values to get:

theta = (pi/8) * 8 = pi radians

Therefore, the angle generated by P in time t is pi radians.

(b) To find the distance traveled by P along the circle in time t, we use the formula for arc length:

s = r * theta

Here, r is given as 16 cm and theta is calculated in part (a) as pi radians. We substitute these values to get:

s = 16 * pi = 16pi cm

Therefore, the distance traveled by P along the circle in time t is 16pi cm.

(c) To find the linear speed of P, we use the formula for tangential velocity:

v = r * omega

Here, r is given as 16 cm and omega is given as pi/8 radians per second. We substitute these values to get:

v = 16 * (pi/8) = 2pi cm/sec

Therefore, the linear speed of P is 2pi cm/sec.

So Katya's rectangular table is 1.6 meters long and 3/4 meters wide, with an area of 1 1/5 square meters.

Area is a measure of the size of a two-dimensional surface, such as the surface of a shape or object. It is usually measured in square units, such as square meters, square centimeters, square feet, or square inches. The area of a shape tells us how much surface area it covers, and is often used in a variety of fields, such as architecture, engineering, and physics. For example, the area of a room can help determine how much flooring is needed to cover it, the area of a building facade can help determine how much material is needed to cover it, and the area of a wing can help determine its lift and drag characteristics in aerodynamics.

Here,

Let's start by using the formula for the area of a rectangle:

A = lw

where A is the area, l is the length, and w is the width.

We are given that the width of the table is 3/4 meters, so we can substitute this value into the formula and simplify:

A = l(3/4)

l = (4/3)A

Next, we are told that the table has an area of 1 1/5 m^2. We can convert this mixed number to an improper fraction by multiplying the whole number by the denominator and then adding the numerator:

1 1/5 = (5*1 + 1)/5 = 6/5

So the area of the table is 6/5 m^2. Substituting this value for A in the formula above, we get:

l = (4/3)(6/5)

l = 8/5 m

Therefore, the length of the table is 8/5 meters, or 1.6 meters when converted to a decimal.
