Answer: $4450.50

Step-by-step explanation:

Just guessed and got it right

The premium of the policy will be $4451.3.

A person or organisation and an insurance company enter into a contract known as insurance whereby the person or organisation pays the insurance company a premium in exchange for financial protection or reimbursement in the case of an unanticipated loss or event. Up to the limitations outlined in the insurance policy, the insurance company promises to pay for any covered losses or damages. Insurance can be used to guard against a range of hazards, such as liability, property damage, death, and injury.

The premium of the policy can be calculated as:

Premium = (Probability of death x Benefit amount) + Administrative costs

So,

Premium = (0.175452 x 25000) + 65

Premium = 4,386.3 + 65

Premium = $4,451.3.

Answer:

A multiple of -6/-3 could be 2

Step-by-step explanation:

A multiple is a number that may be divided by another a certain number of times without a remainder. When we divide -6/-3 we get -2 which is rational and doesn't have any remainder.

The correct answer is c) from ice to the tea.

Temperature is a degree of hotness or coldness the can be measured using a thermometer. It's also a measure of how fast the atoms and molecules of a substance are moving. Temperature is measured in degrees on the Fahrenheit, Celsius, and Kelvin scales.

Heat always flows from warmer objects to cooler objects, so the heat will flow from the 80°C tea to the 0°C ice cube. The ice cube will absorb the heat from the tea and reduce its temperature, cooling it off. The air around the cup will remain at 25°C and no heat will flow from the tea or the ice cube to the air.

Therefore, option C is the correct answer.

We developed three functions to model student attendance, per-student expenditure, and total food cost. S(t) = 150 * (1 + 0.08)^t models the number of students, A(t) = 10 * (1 - 0.04)^t models the cost per student, and E(t) = S(t) * A(t) models the total cost.

We are asked to model the predicted number of students, the amount spent per student and the total expense for food per year over time.

A. The function S(t) = 150 * (1 + 0.08)^t represents the predicted number of students over time.

B. The function A(t) = 10 * (1 - 0.04)^t represents the predicted amount spent per student over time.

C. The function E(t) = S(t) * A(t), represents the total predicted expense for food each year over time.

So, 'S(t)' represents the increase of students, 'A(t)' represents the decrease in the amount spent per student, and 'E(t)' the total expenditure of food each year.

The probability of Kate taking a peach yogurt for the first time is = 2/9

The probability of Kate taking a cherry yogurt first time is = 4/9

Now for the second time, the total number of yogurts will change from 9 to 8 as any one of the yogurts has been consumed by kate so find the probability of kate eating yogurt will be subtracted by 1 if she had already consumed it once.

Answer:

Sophie

Step-by-step explanation:

For each runner, divide their time running by the laps they ran.

Piper: 8÷3≈2.7

Walker: 25÷10=2.5

Sophie: 3÷1=3

Sophie takes the longest time to run one lap, she is the slowest.

Answer:

Sophie is the slowest runner.

Step-by-step explanation:

We are given the various constant of proportionally s.

3:8, 10:25, & 1:3

Simplify each one by finding a least common factor, LCF, for the first side of such, and multiply the number that would be needed to get to such on both sides.

Thus,  30 laps in 80 seconds , 30 laps in 75 seconds , and 30 laps in 90 seconds.

As seen here, 30:90 is lowest, so Sophie is the slowest runner.

Hope this helped!

The question asks to compare the unit rates of two joggers, John and Tyrone. John's unit rate is 5 miles per hour, as indicated by the equation y=5x. Without Tyrone's graph data, a direct comparison cannot be made.

The subject of the question involves comparing unit rates of two joggers, which requires an understanding of linear equations and graph interpretations in mathematics. Based on the given information, John's jogging pace is defined by the linear equation y=5x, where y is the number of miles he jogs and x is the number of hours he jogs. This equation suggests that John's unit rate, or his speed, is 5 miles per hour. However, to compare John's unit rate to Tyrone's, we need additional information about the slope of Tyrone's graph, which represents his speed.

Without the specific graph or a defined equation for Tyrone's pace, we can't make a direct comparison. Typically, the unit rate for a jogger is found by taking the slope of the position vs. time graph, which involves dividing the change in position (the rise) by the change in time (the run). If the slope of Tyrone's graph were provided, we could determine his speed and compare it to John's.

Remember, the unit rate is a measure of how much of something occurs per unit of another thing. In this case, it's the speed at which each jogger moves per hour. If additional data from Tyrone's graph were given, we would look for a constant rate of change or identify two points on the graph to calculate the slope (speed) and thus compare the unit rates of the two joggers.

Answer:

k = 45

angle measures are 45, 90, and 45

Step-by-step explanation:

The sum of angle measures is 180

180 = 45 + 2k + k or

180 = 45 + 3k

subtract 45 from both sides

135 = 3k

Divide by 3

45 = k

Answer:

see explanation

Step-by-step explanation:

The sum of the 3 angles in the triangle = 180°

Sum the 3 angles and equate to 180, that is

2k + k + 45 = 180

3k + 45 = 180 ( subtract 45 from both sides )

3k = 135 ( divide both sides by 3 )

k = 45

------------

Thus 2k = 2 × 45 = 90

The 3 angles are 45°, 45° and 90°
