Step-by-step explanation:
Factor the following:
36 y^2 + 48 x y + 16 x^2
Hint: | Factor out the greatest common divisor of the coefficients of 36 y^2 + 48 x y + 16 x^2.

m∠KLM = 100
Step-by-step explanation:
First, make both equal to each other
26x + 22 = 38x - 14
Subtract 26x from both sides
22 = 12x - 14
Add 14 to both sides to isolate the variable
32 = 12x
Divide both sides by 12
x = 3
----------------- To find m∠KLM take one angle:
38x - 14
Replace the x with 3

Amy has a bag of red, blue, and black pens. she randomly selects a pen, records the color, and puts it back in the bag. she does this a total of 30 times and selects 6 red, 10 blue, and 14 black pens.
based on this information, what is the probability that Amy will select a blue pen, return it to the bag, and than select a red pen?
Answers
Since these two events are independent (the first draw does not affect the second draw), we can multiply the probabilities together to find the probability of both events occurring:
P(blue, then red) = P(blue) × P(red) = (1/3) × (1/5) = 1/15
Therefore, the probability that Amy will select a blue pen, return it to the bag, and then select a red pen is 1/15.

_____
Comment on the question
Temperature in degrees Fahrenheit is reported using an interval scale, not a ratio scale. The notion of a percentage change in temperature measured by such a scale makes no mathematical sense.
Yes, you can perform percentage-like operations on the numbers (which is what we did here), but the idea that 116 °F is a 16% higher temperature than 100 °F is complete nonsense. For such ratios to be meaningful, an absolute temperature scale is needed, such as the Kelvin or Rankine scales.

O 0.9665
O 0.9978
Answers
Using the normal distribution and the central limit theorem, it is found that the probability the mean cost of the weddings is more than the mean cost of the showers is of 0.9665.
Normal Probability DistributionIn a normal distribution with mean \(\mu\) and standard deviation \(\sigma\), the z-score of a measure X is given by:
\(Z = \frac{X - \mu}{\sigma}\)
It measures how many standard deviations the measure is from the mean. After finding the z-score, we look at the z-score table and find the p-value associated with this z-score, which is the percentile of X.By the Central Limit Theorem, the sampling distribution of sample means of size n has standard deviation \(s = \frac{\sigma}{\sqrt{n}}\).When two variables are subtracted, the mean is the subtraction of the means, while the standard error is the square root of the sum of the variances.What is the mean and the standard error of the distribution of differences?For each sample, they are given by:
\(\mu_W = 82.3, s_W = \frac{18.2}{\sqrt{9}} = 6.0667\)
\(\mu_S = 65, s_S = \frac{17.73}{\sqrt{6}} = 7.2382\)
For the distribution of differences, we have that:
\(\mu = \mu_W - \mu_S = 82.3 - 65 = 17.3\)
\(s = \sqrt{s_W^2 + s_S^2} = \sqrt{6.0667^2 + 7.2382^2} = 9.4444\)
The probability the mean cost of the weddings is more than the mean cost of the showers is P(X > 0), that is, one subtracted by the p-value of Z when X = 0, hence:
\(Z = \frac{X - \mu}{\sigma}\)
By the Central Limit Theorem
\(Z = \frac{X - \mu}{s}\)
\(Z = \frac{0 - 17.3}{9.4444}\)
\(Z = -1.83\)
\(Z = -1.83\) has a p-value of 0.0335.
1 - 0.0335 = 0.9665.

Answers
James has a total of 21.9 kilograms of sand in his sandbox after adding the sand from the beach. To find the total weight of sand in James' sandbox, we need to convert the given weights from grams to kilograms.
James initially has 14,500 g of sand. To convert this to kilograms, we divide by 1000:
14,500 g ÷ 1000 = 14.5 kg
Next, James brings home an additional 7,400 g of sand from the beach. To convert this to kilograms, we divide by 1000:
7,400 g ÷ 1000 = 7.4 kg
To find the total weight of sand in James' sandbox, we add the initial amount of sand to the amount he brought from the beach:
14.5 kg + 7.4 kg = 21.9 kg
Therefore, James now has 21.9 kilograms of sand in his sandbox.

D.1 Give an estimate for the total volume of food and water you've ingested in the last day, in milliliters. D.2 How many times larger is the amount of blood your heart has pumped in the last day than the amount of food and drink you took in? D.3 How much error do you expect in your answer to 4 b ? You should give an quantitative response to this, but not one generated by a formula. Instead, estimate the error by examining how closely you think you know the values you estimated for food intake and blood flow. You don't need to use advanced error propagation; an approximate response is fine. D.4 What is the relevance of this calculation to the theory that all the blood that flows through your veins is generated in the liver?
Answers
An estimate for the total volume of food and water you've ingested in the last day is 3000-5000 milliliters. On average, the heart pumps about 5 liters of blood per minute. 10-20% or more error I'm expecting. Calculating heart blood volume compared to food and drink consumption is crucial for understanding circulation and liver function.
D.1 Estimating the amount of food and water consumed in a day can be difficult without specific measurements, but a rough estimate can be made based on typical intake amounts. On average, a person may consume 2-3 liters of water and 1000-2000 calories per day, resulting in an estimated total volume of 3000-5000 milliliters.
D.2 The amount of blood pumped by the heart varies from person to person and depends on factors such as heart rate and overall health. On average, the heart pumps about 5 liters of blood per minute, which is much larger than the estimated volume of food and water intake.
D.3 Estimating food and water intake and blood flow is prone to error due to variability and uncertainties in personal measurements. Individuals' habits, health, and physical activity levels can affect these estimates, potentially resulting in a significant error of 10-20% or more.
D.4 The calculation of the heart's blood volume compared to food and drink consumption is crucial for understanding the circulation system and liver role.
The liver processes nutrients, detoxifies, and produces blood components, while the heart is responsible for circulating blood throughout the body. The vast difference in volume between the two is emphasized, emphasizing the heart's crucial role in maintaining circulation.

Answers
The car will need 6 gallons of gasoline to travel 102 miles
Explanation:Given that the car travels 442 miles on 26 gallons of gasoline.
Because the more the distance, the more the volume of gasoline used, this is a direct proportion.
So, we have:
\(\begin{gathered} V=\frac{102\times26}{442} \\ \\ =6 \end{gathered}\)It will need 6 gallons.
A cyclist rides into the country at an average speed of 10 miles per hour. When his bike gets a flat tire, he walks it back at an average speed of 3 miles per hour. If he returns home 6 and a half hours after he starts, how far into the country does he go?
Answers
The distance the cyclist traveled into the country, given that he rides into the country at an average speed of 10 miles per hour is 15 miles
How do i determine the distance traveled?Let the total distance traveled into the country be y.
Now, we shall determine the riding time. Details below:
Speed = 10 mile per hourDistance traveled = yRiding time = ?Riding time = Distance / speed
Riding time = y / 10
Next, we shall obtain the walking time of the cyclist. This is shown below:
Speed = 3 mile per hourDistance traveled = yWalking time = ?Walking time = Distance / speed
Riding time = y / 3
Finally, we shall obtain the total distance traveled. This is illustrated below:
Riding time = y / 10Riding time = y / 3Total time = 6.5 hoursTotal distance = y =?Total time = riding time + walking time
6.5 = y/10 + y/3
6.5 = (3y + 10y) / 30
6.5 = 13y / 30
Cross multiply
13y = 6.5 × 30
13y = 195
Divide both sides by 13
y = 195 / 13
y = 15 miles
Thus, the total distance traveled by the cyclist into the country is 15 miles.

The terminal ray of ZA passes through the point (10, — 4).
Answers
Answer:
In standard position, the terminal ray of angle A passes through the point (10,-4) on the coordinate plane. The distance of the point (10, -4) from the origin (0,0) is the hypotenuse of a right triangle. The horizontal distance of the point from the y-axis is the x-coordinate, which is 10, and the vertical distance of the point from the x-axis is the y-coordinate, which is -4.
The secant of an angle is the ratio of the hypotenuse (c) to the adjacent side (a). In this case, the hypotenuse is the distance between the point (10, -4) and the origin (0,0) and the adjacent side is the x-coordinate which is 10.
So sec(A) = c/a = √(10² + (-4)²)/10 = √(100+16)/10 = √116/10 = √29/5
So sec(A) = √29/5 which is the simplified form.
