Samadhi paid $1.32 more than Karega for her chocolate.

The subject of this question is in Mathematics, specifically it involves unit conversion and arithmetic calculations. We know that chocolate costs $17.60 per kilogram. But Karega and Samadhi are buying chocolate in grams which means we need to convert the cost from kilograms to grams. 1 kilogram is equal to 1000 grams. So, cost of chocolate per gram = $17.60/1000 = $0.0176.

Karega is buying 25 grams of chocolate, so the cost = 25 * $0.0176 = $0.44. Samadhi is buying 100 grams of chocolate, so the cost =$0.0176 * 100 = $1.76. To find out how much more Samadhi paid for her chocolate compared to Karega, we subtract Karega's cost from Samadhi's cost which gives $1.76 - $0.44 = $1.32.

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.

Final answer:

3.24 with the digit 4 repeating can be converted into the simplified fraction ⅔, which is equivalent to 3 ½.

Explanation:

The student is asking how to express the decimal 3.24 with the digit 4 repeating as a simplified fraction. The repeating decimal can be represented as 3.244444... or 3.24 bar.

To convert this repeating decimal to a fraction, we first denote x = 3.24. To eliminate the repeating part, we can multiply x by 100 to shift the decimal two places to the right, getting 100x = 324.44. Then, we subtract the original equation from this new equation (100x - x) to remove the repeating decimal. This results in 99x = 321, which simplifies to x = ⅔ or x = 3 ½ in fraction form. Therefore, 3.24 bar as a simplified fraction is ⅔.

Answer:

8/27

Step-by-step explanation:

The probability of rolling a number less than 3 three times in a row on a number cube (or die) is 1/27.

The subject of this question is probability in mathematics. A number cube, often referred to as a die, has six faces numbered 1 through 6. If we are looking for the probability of rolling a number less than 3, we are looking for the probability of rolling a 1 or a 2. Out of six possibilities, two are successful outcomes (1 and 2), so the probability of rolling a number less than 3 in one roll is 2 out of 6, or 1/3.

However, since the number cube is rolled three times, we have to consider this probability for each roll. In probability, when we want to find the likelihood of multiple events all occurring, we multiply the probabilities of each individual event. Therefore, the probability of rolling a number less than 3 three times in a row is (1/3) * (1/3) * (1/3) = 1/27.

Step-by-step explanation:

Answer:

.004 %

Step-by-step explanation:

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.

a) Find the rate of depreciation given that ;

The car was bought at $10,250 when it was 5 years old

After 2 years, the value was $8,075

Apply the formula ;

current price= original price *(1-r)^n

8,075=10,250* (1-r)²

8,075/10250 = (1-r)²

0.78780487804 =(1-r)²

√0.78780487804 =(1-r)

0.88758373016 = 1-r

r=1-0.88758373016

r=0.11241626983 ⇒ 11.24%

Answer: There is NO correlation between international flights and a flight being late.

Step-by-step explanation:

See attachment for rationale and step by step.

a) The value of x as calculated in the image is 45 degrees.

b) For the lines AD and BC to be parallel in a quadrilateral, the opposite angles need to be supplementary (i.e., their sum should be 180 degrees).

In this case, angle A is:

2x = 245 = 90 degrees

and angle D is:

3x = 345 = 135 degrees.

Since 90 + 135 = 225 degrees, which is not equal to 180 degrees, the lines AD and BC would not be parallel when ABCD is drawn to scale.
