Answer:

True

Step-by-step explanation:

They will be equal at the same altitude at x= 48 seconds

Assume the question is when the planes will be at the same altitude.

A is 2184+30.25x, where x is the number of seconds.

The aircraft B is 75.75x

They will be equal at the same altitude if

75.75x=2184+30.25x

Collecting like terms and making x the subject of the relation

75.75x -30.25x = 2184

45.5x = 2184

Making x the subject

x = 2184/45.5

x=48 seconds

The two airplanes  will be at the same altitude at 48 seconds

False. the denominator in the formula for calculating the return on investment includes operating and nonoperating assets.

The denominator in the formula for calculating the return on investment (ROI) typically includes only operating assets, not non-operating assets. Operating assets are those that are necessary to generate revenue and include items such as inventory, equipment, and property. Non-operating assets, on the other hand, are not directly related to revenue generation and include items such as investments, patents, and trademarks. In order to calculate ROI, the numerator is the profit or gain from the investment, while the denominator is typically the total amount of operating assets used to generate that profit. By dividing the profit by the investment, ROI provides a measure of how much profit was generated relative to the amount of resources invested.

The average working hours of the employee is 5.7 hours per day.

To find the average working hours of the employee, we need to add up all the working hours for the 10 days and then divide by 10 (the number of days):

10 + 5 + 7 + 4 + 8 + 6 + 7 + 6 + 4 = 57

Now we divide by 10:

57 / 10 = 5.7

Therefore, the average working hours of the employee is 5.7.

Answer:

- 1 , - 7 , 5

Step-by-step explanation:

let the 3 numbers be a₁ , a₂ and a₃ , then

a₁ + a₂ + a₃ = - 3 ( substitute a₁ + a₂ = - 8 )

- 8 + a₃ = - 3 ( add 8 to both sides )

a₃ = 5

Now

a₁ + a₂ = - 8 ( subtract a₁ from both sides )

a₂ = - a₁ - 8 → (1)

given a₂ - a₃ = a₁ + 1 , that is

a₂ - 5 = a₁ + 1 ( add 5 to both sides )

a₂ = a₁ + 6 → (2)

substitute a₂ = a₁ + 6 into (1)

a₁ + 6 = - a₁ - 8 ( add a₁ to both sides )

2a₁ + 6 = - 8 ( subtract 6 from both sides )

2a₁ = - 14 ( divide both sides by 2 )

a₁ = - 7

substitute a₁ = - 7 into (1)

a₂ = - (- 7) - 8 = 7 - 8 = - 1

The largest integer less than 2010 that has a remainder of 5 when divided by 7, a remainder of 10 when divided by 11, and a remainder of 10 when divided by 13. is 1440

Given, a number less than 2010 that has a remainder of 5 when divided by 7, a remainder of 10 when divided by 11, and a remainder of 10 when divided by 13.

On using the Chinese remainder theorem. As, the numbers 7, 11, 13 are pairwise coprime.

Firstly, an integer  m  such that  m−5  is divisible by 7 and  m−10  is divisible by 11 .

The Chinese remainder theorem says that all integers that work will be of the form  54+7⋅11⋅k=54+77k  for any integer  k .

Next an integer  n  such that  n−10  is divisible by 13 and  n−54  is divisible by 77.

Then, by the Chinese remainder theorem, all the integers that also work are of the form  439+13⋅77⋅k=439+1001k .

Hence, the positive integers satisfying the condition are: 439, 439 + 1001 = 1440, 1440 + 1001 = 2441, and so on.

The largest integer less than 2010 is 1440.

If Steve spent $23.75 on 10 kids if they each bought either a hotdog or hamburger that cost $1.50 each and $2.75 each respectively, then the number of hotdog he bought is 3 and the number of hamburger he bought is 7.

Let the number of kids who choose hotdog be x and hamburger be y. As there are 10 kids in total

x + y = 10

Cost of one hot dog is $1.50 and the cost of one hamburger is $2.75. Therefore

1.50x + 2.75y = 23.75

Let us assume Steve bought an equal amount of hamburgers and hot dogs, that is x = y. Then

1.50x + 2.75x = 23.75

4.25x = 23.75

x = 95/17

That is x is not a natural number which is not possible as it is the number of kids. So our assumption is wrong. So Steve would not have bought an equal amount of hamburgers and hot dogs.

Solving x + y = 10 and 1.50x + 2.75x = 23.75

y = 7 and x = 3

So the number of hotdog he bought is 3 and the number of hamburger he bought is 7.

The largest side of the triangle is 52.

Checking pythagoraus theorem,

Thus, it is not a right angle triangle.

Thus, option (D) is correct.

The probability of drawing a random sample of 5 red cards is 0.002641 or 0.2641%. It is not unusual to draw a random sample of 5 red cards since the probability is not very low, in fact, it is above 0.1%.  

In a standard deck of 52 playing cards, there are 26 red cards (13 diamonds and 13 hearts) and 52 total cards. Suppose we draw a random sample of five cards from this deck.  We will solve this problem using the formula for the probability of an event happening n times in a row: P(event)^n.For the first card, there are 26 red cards out of 52 cards total. So the probability of drawing a red card is 26/52 or 0.5.

For the second card, there are 25 red cards left out of 51 total cards. So the probability of drawing another red card is 25/51.For the third card, there are 24 red cards left out of 50 total cards. So the probability of drawing another red card is 24/50.For the fourth card, there are 23 red cards left out of 49 total cards. So the probability of drawing another red card is 23/49.For the fifth card, there are 22 red cards left out of 48 total cards. So the probability of drawing another red card is 22/48.

The probability of drawing five red cards in a row is the product of these probabilities:

P(5 red cards in a row) = (26/52) × (25/51) × (24/50) × (23/49) × (22/48)

= 0.002641 (rounded to six decimal places).

The probability of drawing a random sample of 5 red cards is 0.002641 or 0.2641%. It is not unusual to draw a random sample of 5 red cards since the probability is not very low, in fact, it is above 0.1%.

Step-by-step explanation:

The simplified expression is 2y² - 9.

To subtract the binomials (-3y^2 - 8) - (-5y^2 + 1), we need to distribute the negative sign to the terms inside the second set of parentheses:

(-3y^2 - 8) - (-5y^2 + 1) = -3y^2 - 8 + 5y^2 - 1

Next, we combine like terms by adding or subtracting the coefficients of the same degree:

-3y^2 + 5y^2 - 8 - 1 = (5y^2 - 3y^2) + (-8 - 1) = 2y^2 - 9

Answer:

It is a function.

Step-by-step explanation:

By definition, a function relates each element in the domain to only one element in the range. This means that each vertical line you draw through the x-axis can intersect the function at only one point. ... y = 2x +1. This is the equation of a straight line with slope 2 and y-intercept 1, so it is a function.

A linear function is two distinct but related notions. So, y=2x-1 is also a linear function.

The approximate area of the trapezoid is determined as  13.95 unit².

The approximate area of the trapezoid is calculated as follows;

Area = ¹/₂(b₁ + b₂)h

Where;

The y-coordinates of the points on the curve at x=3/2 and x=4 is calculated as follows;

y(3/2) = - (3/2)²/2 + 3/2 + 5

y(3/2) = -9/8 + 3/2 + 5

y(3/2) = 5.375

y(4) = -4²/2 + 4 + 5

The number of days during the next year when she did not receive a phone call from any of her grandchildren was 304. Mrs. Sanders received a call from each of her three grandchildren on December 31, 2016.

Mrs. Sanders received a call from each of her three grandchildren on December 31, 2016. Let's suppose the number of days that pass between the calls made by the first, second, and third grandchildren are a, b, and c days, respectively. The first grandchild calls her every three days, so the next time the grandchild would call would be on January 3, 2017 (3 days after December 31, 2016). Similarly, the second grandchild calls her every four days, so the next time the grandchild would call would be on January 4, 2017 (4 days after December 31, 2016). Lastly, the third grandchild calls her every five days, so the next time the grandchild would call would be on January 5, 2017 (5 days after December 31, 2016). Therefore, the first call in 2017 would be on January 3, 2017, and the next call would be made after (LCM of 3, 4, and 5) - 1 days.

Here, the LCM of 3, 4, and 5 is 60, and so the first time she does not receive a call would be on the 61st day (February 28, 2017) because February has only 28 days (29 days in leap year).In the year 2017, Mrs. Sanders would receive calls on 6th, 8th, 9th, 11th, 12th, 14th, 16th, 17th, 19th, 21st, 22nd, 24th, 26th, 27th, 29th, 31st of January;

Answer:

Step-by-step explanation:

Given ΔABC with vertices:

We observe that

AB is vertical segment with length:

BC is horizontal segment with length:

The area:

The mean is 18.6.

Given the following information; z = 2.25, x = 22.2, and σ = 1.6, to find the mean, we have to apply the formula for z-score. z = (x - μ)/σWhere; z-score is represented by z, the value of X is represented by x, the mean is represented by μ and the standard deviation is represented by σSubstituting the values into the equation above;2.25 = (22.2 - μ)/1.6Multiplying both sides of the equation by 1.6, we have;1.6(2.25) = (22.2 - μ)3.6 = 22.2 - μ Subtracting 22.2 from both sides of the equation;3.6 - 22.2 = - μ-18.6 = - μ Multiplying both sides of the equation by -1, we have;μ = 18.6

Simply said, a z-score, also known as a standard score, informs you of how far a data point is from the mean. Technically speaking, however, it's a measurement of how many standard deviations a raw score is from or above the population mean.

You can plot a z-score on a normal distribution curve. Z-scores range from -3 standard deviations, which would fall to the extreme left of the normal distribution curve, to +3 standard deviations, which would fall to the far right. You must be aware of the mean and population standard deviation in order to use a z-score.

The z-score can show you how that person's weight compares to the mean weight of the general population.
