Answer:

595.

Step-by-step explanation:

Take $2000 and subtract $810 from it. You now have the total of the two pieces of equipment without the extra pricing. You should get $1,190. Then divide that number by 2. You will get $595.

1st Piece of Equipment = $595

2nd Piece of Equipment = $1,405

2nd Piece is $810 more expensive and the two pieces combined is $2,000.

The mean number of movies that the students saw is 13.5 (rounded to the nearest tenth).

To find the mean number of movies the students saw, you need to calculate the average of the given data. Here are the reported numbers of movies seen by the 6 students: 14, 11, 15, 19, 12, 10.

To calculate the mean, you sum up all the reported numbers and divide by the total number of students. In this case, the total number of students is 6.

So, let's calculate the mean:

(14 + 11 + 15 + 19 + 12 + 10) / 6 = 81 / 6 = 13.5

Therefore, the mean number of movies that the students saw is 13.5 (rounded to the nearest tenth).

Roland's percent error is approximately 3.889%.

This means that his measured value differs from the actual value by 3.889% or 0.03889 in decimal form.

The positive sign indicates that Roland's measured value is slightly lower than the actual value.

To calculate Roland's percent error, we can use the formula:

Percent Error = (|Measured Value - Actual Value| / Actual Value) \(\times\) 100

Given that Roland measured a current of 0.173 amps while expecting a current of 0.180 amps, we can substitute these values into the formula:

Percent Error = (|0.173 - 0.180| / 0.180) \(\times\) 100

Simplifying the expression within the absolute value:

Percent Error = (|-0.007| / 0.180) \(\times\) 100

Since the absolute value of -0.007 is 0.007, we have:

Percent Error = (0.007 / 0.180) \(\times\) 100

Calculating the division:

Percent Error = 0.03889 \(\times\) 100

Percent Error = 3.889%.

The statement about the unit prices which is true is Kitty Kibbles has a lower unit price of $1.30/pound.

The correct answer choice is option D.

Cost of 16-pound bag of Kitty Kibbles = $20.80

Unit price of kitty kibbles = Price / number of pounds

= $20.80 / 16

= $1.30 per pound.

Cost of 8-pound bag of Feline flavor = $11.20

Unit price of feline flavor = Price / number of pounds

= $11.20 / 8

= $1.40 per pound

y2 = 4

y1 = a

x2 = 5

x1 = 3

Formula

m  = (y2 - y1)/(x2 - x1)

The expected value of the outcome of the bid is $0.18

So let's start by counting how many bids are placed up to a total of 160.

100*160 = 16000.

What will be your arbitrary bid? As each bid has an equal chance of success, the average of all bids is used. (One cent plus 160 dollars) / 2 = 80 dollars (rounded)

Your odds of winning are 1/16000 (1 bid out of 16000).

If you win, your profit is 1920 ($2000 minus $80.00).

1920/16000 is $0.12

Your cost to enter the auction is $1, and your average winning offer is $0.12.

The result is $0.18 (0.12-1=-0.88).

Thus the expected value of the outcome of the bid is $0.18

Answer:

Step-by-step explanation:

The last-minute cancellations of two families (11 people in total) due to illness may affect the decision as to which company offers more favorable terms, depending on the specific circumstances and fee structures of the companies involved.

If the rate is based on per person, canceling 11 people would significantly reduce the total cost for both companies. In this case, one would compare the changed prices of each company to determine which one offers the better deal.

However, with flat-rate pricing regardless of the number of participants, the cancellation of 11 people would not affect costs for either company. In such a scenario, the cancellation will not affect the evaluation of which company presents the better offer.

For the first set of numbers, \(12+16\ngeq29\), so it doesn't represent the three sides of a triangle

For the second set of numbers, \(14+21\ngeq36\), so it doesn't represent the three sides of a triangle

For the third set of numbers, \(14+28\geq39\), so it does represent the three sides of a triangle

For the fourth set of numbers, \(8+14\ngeq24\), so it doesn't represent the three sides of a triangle

Answer:

The car will depreciate at a rate of 21.14% per year.

Step-by-step explanation:

Given that the value of a car will “depreciate” over time, and, for example, a car that was worth $ 24,000 when it was new, is being sold for $ 13,500 three years later, to determine the annual depreciation rate on this car the following calculation must be performed:

13,500 x (1 + X) ^ 1x3 = 24,000

13,500 x (1 + 0.2114) ^ 3 = 24,000

X = 21.14%

Therefore, the car will depreciate at a rate of 21.14% per year.

Answer:

x = 7

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion , that is

\(\frac{AC}{XZ}\) = \(\frac{BC}{YZ}\) ( substitute values )

\(\frac{12x-63}{7x-14}\) = \(\frac{6}{10}\) = \(\frac{3}{5}\) ( cross- multiply )

5(12x - 63) = 3(7x - 14) ← distribute parenthesis

60x - 315 = 21x - 42 ( subtract 21x from both sides )

39x - 315 = - 42 ( add 315 to both sides )

39x = 273 ( divide both sides by 39 )

x = 7

The solution of the equation 4x - 3  = 5 is not extraneous .

Extraneous solutions are values that we get when solving equations that aren't really solutions to the equation.

Therefore, let's solve the equation to know whether it is extraneous solution.

Hence,

4x - 3  = 5

add 3 to both sides of the equation

4x - 3 + 3 = 5 + 3

4x = 8

divide both sides of the equation by 4

4x / 4 = 8 / 4

x = 2

Therefore, it is not extraneous solution.

The probability of rolling a number that is either a prime number greater than 2 and ending in 6, or the number 7, is 5/10 or 1/2.

The chance or potential of a result is referred to as probability. It explains the probability of a particular occurrence.

The chance of rolling a prime number or a 6' prime prime on a die is the total of the probabilities of rolling each of those numbers, assuming that the 10-sided die is fair and that all sides are equally likely to land face up.

A 10-sided dice has the following four prime numbers: 2, 3, 5, and 7. Moreover, there is only one number that is 6' prime (or 6"), and that number is 9. Only one number exists, and that is seven. Hence, the likelihood that a prime number or 6' prime prime will be rolled is:

P(prime or 6' prime prime) = P(2) + P(3) + P(5) + P(7) + P(9)

Since there are 10 possible outcomes, each with an equal probability of 1/10, the probability of rolling any single number is 1/10. Therefore:

P(2) = P(3) = P(5) = P(7) = 1/10

P(9) = 1/10

Substituting these values into the equation above gives:

P(prime or 6' prime prime) = 1/10 + 1/10 + 1/10 + 1/10 + 1/10

1/10 = 6/10 = 3/5

Therefore, the probability of rolling a prime number or 6' prime prime on a 10-sided die is 3/5.

For Given Fraction 5/3, The total number of votes is 7648.

What is a fraction?

In Maths, a fraction is used to represent the portion/part of the whole thing. It represents the equal parts of the whole. A fraction has two parts, namely numerator and denominator. The number on the top is called the numerator, and the number on the bottom is called the denominator. The numerator defines the number of equal parts taken, whereas the denominator defines the total number of equal parts in a whole.

For example, 5/10 is a fraction.

Here, 5 is a numerator and 10 is a denominator.

There are four different types of fractions. They are:

Unit Fraction – In a fraction, the numerator with 1 is called a unit fraction. For example, ½, ¼

Proper Fraction – If a numerator value is less than the denominator value, it is called a proper fraction. Example: 7/9, 8/10

Improper Fraction – If a numerator value is greater than the denominator value, then it is called an improper fraction. Example: 6/5, 11/10

Mixed Fraction – If a fraction consists of a whole number with a proper fraction, it is called a mixed fraction. Example 5 ¾, 10 ½

Now,

As given ratio is 5/3 for Yes votes to no votes

so total votes is 5x+38x

and also given that no votes i.e. 3x=2868

so, x=956

Hence,

Combine like terms

2w+7 = 2w+2

Subtract 2w from each side
