Three numbers whose sum is 26 are in GP.If 5,9 and 5 are added to them respectively, then the three numbers are in AP. Find the numbers.​

The distance a car travels varies directly with the amount of gasoline it uses. If a car uses 28 gallons of gasoline to travel 924 miles, the car can travel 627 miles with 19 gallons of gasoline.

We can set up a proportion to solve the problem:

distance / gasoline = constant

Let's use x to represent the distance the car can travel with 19 gallons of gasoline:

924 / 28 = x / 19

Simplifying and solving for x:

x = (924 / 28) * 19 = 627 miles

Therefore, the car can travel 627 miles with 19 gallons of gasoline.

The five number summary for Mrs. Tinney's class is: 0, 72, 85, 96.5, 100. Tinney's class has a smaller IQR. We would need to look at a histogram or box and whisker plot to confirm these conjectures.

The median is a statistical measure that represents the middle value of a dataset. It is the value that separates the lower half of the dataset from the upper half. To find the median, the data must be arranged in order from smallest to largest, and then the middle value is identified.

If the dataset contains an odd number of values, then the median is the middle value. For example, if the dataset is {2, 4, 6, 7, 9}, then the median is 6, which is the middle value.

If the dataset contains an even number of values, then the median is the average of the two middle values. For example, if the dataset is {2, 4, 6, 7, 9, 10}, then the median is (6+7)/2 = 6.5, which is the average of the two middle values, 6 and 7.

To find the five number summary for Mrs. Tinney's class, we first need to order the scores from least to greatest:

0, 16, 72, 78, 80, 85, 88, 95, 98, 100

The minimum score is 0 and the maximum score is 100.

The median is the middle score, which is 85.

To find the first quartile, we split the scores into two halves at the median and find the median of the lower half:

0, 16, 72, 78, 80

The median of the lower half is 72.

To find the third quartile, we find the median of the upper half:

88, 95, 98, 100

The median of the upper half is 96.5.

Therefore, the five number summary for Mrs. Tinney's class is: 0, 72, 85, 96.5, 100.

To compare the consistency of the two classes, we can look at the interquartile ranges (IQRs), which give the range of scores that contain the middle 50% of the data. The IQR for Mrs. Tinney's class is 96.5 - 72 = 24.5, while the IQR for Mrs. Aguiar's class is 90 - 50 = 40. Mrs. Tinney's class has a smaller IQR, which means that their scores are more consistent.

The means for the two classes suggest that the data may not be symmetric. If the data were symmetric, we would expect the means to be roughly in the middle of the data set. However, the mean for Mrs. Aguiar's class is closer to the upper end of the data set, which suggests that the data may be skewed to the right. The mean for Mrs. Tinney's class is closer to the lower end of the data set, which suggests that the data may be skewed to the left. However, we would need to look at a histogram or box and whisker plot to confirm these conjectures.

The percentage error between the estimated age and the carbon-14 dating age of the fossil is 12.5% and an estimated age of approximately 2978 years would give the same percent error of 12.5%.

What is the definition of percentage?

Percentage is a way of expressing a fraction or proportion as a part of 100. It is denoted by the symbol "%". The term "percent" means "per hundred". For example, if 50% of a group of people are men, it means that 50 out of every 100 people in the group are men.

Now,

a). To find the percent error between the estimated age and the carbon-14 dating age of the fossil, we can use the formula:

percent error = |(estimated age - carbon-14 dating age) / estimated age| x 100%

Substituting the given values, we get:

percent error = |(3200 - 3600) / 3200| x 100%

= |-400 / 3200| x 100%

= 12.5%

Therefore, the percent error between the estimated age and the carbon-14 dating age of the fossil is 12.5%.

b). To find other estimates that give the same percent error, we can use the formula:

percent error = |(estimated age - carbon-14 dating age) / estimated age| x 100%

If we let x be the estimated age that gives the same percent error, then we can write:

12.5% = |(x - 3600) / x| x 100%

Simplifying, we get:

0.125 = |(x - 3600) / x|

Taking the positive square root of both sides (since percent error cannot be negative), we get:

√0.125 = (x - 3600) / x

Simplifying, we get:

x = 3600 / (1 - √0.125)

x ≈ 2978

Therefore, an estimated age of approximately 2978 years would give the same percent error of 12.5% as the original estimated age of 3200 years. This means that if the fossil were actually 2978 years old, the carbon-14 dating would have given an age estimate of approximately 3299 years, which is 12.5% higher than the true age.

Samantha needs to mix 10 milliliters of the 40% alcohol solution with 90 milliliters of the 60% alcohol solution to create 100 milliliters of a 58% solution.

Let x be the number of milliliters of the 40% alcohol solution that Samantha needs to mix, and let y be the number of milliliters of the 60% alcohol solution. Since Samantha needs to create 100 milliliters of a 58% solution, we can write the following system of equations:

x + y = 100 (equation 1: total volume)

0.4x + 0.6y = 0.58(100) (equation 2: alcohol concentration)

In equation 1, we see that the total volume of the resulting mixture must be 100 milliliters. In equation 2, we convert the concentration of the 58% solution into a decimal and set it equal to the weighted average of the concentrations of the two solutions.

We can solve this system of equations to find the values of x and y:

x + y = 100

0.4x + 0.6y = 58

Multiplying the first equation by 0.4, we get:

0.4x + 0.4y = 40

Subtracting this equation from the second equation, we get:

0.2y = 18

y = 90

Substituting y = 90 into equation 1, we get:

Answer:

x = -4,

y = -1

Step-by-step explanation:

{-3x - 8y = 20,

{-5x + y = 19;

Make x or y the subject from either the 1st or the 2nd equation (I chose to make x the subject from the 2nd equation, because after division, the numbers can be written as a finite decimal fraction):

-5x = 19 - y / : (-5)

x = -3,8 + 0,2y

Replace x in the 1st equation with its value from the 2nd one (the underlined expression):

-3(-3,8 + 0,2y) - 8y = 20

Multiply every term inside the bracket by the term on the outside:

11,4 - 0,6y - 8y = 20

Collect like terms and add them together:

-8,6y = 20 - 11,4

-8,6y = 8,6 / : (-8,6)

y = -1

y = -1x = -3,8 + 0,2 × (-1) = -4

The probability that the mean battery life would be greater than 1173.8 minutes is 0.9588

We can solve this problem using the central limit theorem, which tells us that the distribution of sample means from a population with a known variance becomes approximately normal as the sample size increases.

The standard error of the mean can be calculated as

SE = σ / sqrt(n)

where σ is the population standard deviation, n is the sample size

Here, we are given that the population variance is 8100, so the population standard deviation is the square root of 8100, which is 90.

SE = 90 / sqrt(72) = 10.6066

Next, we need to standardize the sample mean using the z-score formula

z = (X - μ) / SE

where X is the sample mean, μ is the population mean.

Here, the population mean is given as 1192 minutes and the sample mean we are interested in is 1173.8 minutes.

z = (1173.8 - 1192) / 10.6066 = -1.7356

We want to find the probability that the sample mean is greater than 1173.8 minutes. Since we have a negative z-score, we need to find the area to the right of this value on a standard normal distribution. We can use a z-table or a calculator to find this probability.

Using a standard normal distribution table, we find that the area to the right of z = -1.7356 is 0.9588.

Let's first calculate how much Darlene will earn in one week by organizing four recycling events:

$200 (base pay) + $25 (per event) x 4 (number of events) = $300

So, if Darlene organizes four recycling events per week, she will earn $300 per week.

To reach her goal of at least $1,200 in four weeks, we can set up the following inequality:

4 x (number of events) x $25 + $200 x 4 ≥ $1,200

100 x (number of events) + $800 ≥ $1,200

100 x (number of events) ≥ $400

(number of events) ≥ 4

Therefore, the number of events Darlene needs to organize to reach her goal of at least $1,200 is at least 4.

Since Darlene plans to organize four recycling events per week, this means she would need to work four weeks to reach her goal. Therefore, organizing four events each week would be enough to meet her goal, as long as she works all four weeks

10. The simplified  expression is -(p + 10)/(p(9 - p)).

What is an expression?

7. To simplify the expression, we can cancel out common factors in the numerator and denominator:

(32x³ * y)/(5x * y²) * (15y)/(8x² *[tex]y^{4}[/tex] )

= (32/5) * (x³/x²) * (1/y²) * (3/2) * (1/x²) * (1/y³)

Therefore, the simplified expression is 96[tex]x^{-1}[/tex][tex]y^{-5}[/tex].

8. The simplified expression is 5(m - 2)/(m - 1).

To simplify the expression, we can factor the numerator:

(m² - 6m + 8)/(2m - 2) = (m - 4)(m - 2)/(2(m - 1))

We can then cancel out common factors:

(m - 4)(m - 2)/(2(m - 1)) * 10/(m - 4)

= 5(m - 2)/(m - 1)

Therefore, the simplified expression is 5(m - 2)/(m - 1).

9. The simplified expression is 3/5.

To simplify the expression, we can first simplify the fractions within the parentheses:

28n + 40/35n + 50 = (4n + 8)/(5n + 10)

12n + 24/8n + 16 = (3n + 6)/(2n + 4)

We can then simplify the expression by multiplying the two fractions:

(4n + 8)/(5n + 10) * (3n + 6)/(2n + 4)

= 2(2n + 4)/(5n + 10) * 3(n + 2)/(2(n + 2))

= 3/5

Therefore, the simplified expression is 3/5.

10. The simplified expression is -(p + 10)/(p(9 - p)).

To simplify the expression, we can factor the second fraction in the numerator and then cancel out common factors:

(p + 10)/(9 - p) * (p² - 5p - 36)/(4p² + 16p)

= (p + 10)/(9 - p) * ((p - 9)(p + 4))/(4p(p + 4))

The largest angle in quadrilateral PQRS is angle R with a measure of 150 degrees.

what is quadrilateral?

A quadrilateral is a four-sided polygon, which is a two-dimensional closed shape with straight sides. In other words, a quadrilateral is a geometric figure that has four sides, four vertices, and four angles. The sum of the interior angles of a quadrilateral is always equal to 360 degrees. Examples of quadrilaterals include squares, rectangles, parallelograms, trapezoids, and kites.

From the given information, we have:

angle P = 3p

angle Q = 4q

angle R = 5r

Since PQRS is a cyclic quadrilateral, the sum of opposite angles is equal to 180 degrees. Therefore, we have:

angle P + angle R = 180 degrees

3p + 5r = 180 degrees

Similarly, we have:

angle Q + angle S = 180 degrees

4q + S = 180 degrees

S = 180 - 4q

To find the largest angle, we need to find the largest angle measure among angles P, Q, R, and S.

Let's substitute the expression for S in terms of q into the equation for angle Q and simplify:

angle Q = 4q

angle Q + angle S = 180 degrees

4q + (180 - 4q) = 180 degrees

4q - 4q + 180 = 180 degrees

180 = 180 degrees

This equation is true, but it does not provide any information about the largest angle in PQRS.

Let's now substitute the expressions for angles P, Q, and R in terms of p and r into the equation for angle P + angle R = 180 degrees:

3p + 5r = 180 degrees

We want to find the largest angle, so we need to find the largest value of p or r that satisfies this equation. One way to do this is to try different values of p and r that satisfy the equation and see which one yields the largest value for angle P or angle R.

Let's try p = 10 and r = 30:

3p + 5r = 3(10) + 5(30) = 150

This satisfies the equation, so we can calculate angle P and angle R:

angle P = 3p = 30 degrees

angle R = 5r = 150 degrees

Therefore, the largest angle in quadrilateral PQRS is angle R with a measure of 150 degrees.
