there is p% chance of raining on saturday and q% chance of raining on sunday. whay is max and min probability of raining on both days?
Answers
The maximum probability of raining on both Saturday and Sunday is min(p%, q%). The minimum probability of raining on both Saturday and Sunday is (p% * q%) / 100.
The maximum probability of raining on both Saturday and Sunday occurs when the probabilities are not independent. In this case, the maximum probability is the minimum of the individual probabilities of raining on each day.
So, the maximum probability of raining on both days is the minimum of p% and q%.
The minimum probability of raining on both days occurs when the probabilities are independent. In this case, we can multiply the individual probabilities of raining on each day to find the minimum probability.
So, the minimum probability of raining on both days is the product of p% and q%.

The radius of a cylindrical water tank is 5.5 ft, and it’s height is 10 ft. What is the volume of the tank?
Answers
Answer:
950.33 ft³
Step-by-step explanation:
The volume of a cylinder is denoted by: V = πr²h, where r is the radius and h is the height.
Here, the radius is r = 5.5 ft and the height is h = 10 ft. Plug these into the formula:
V = πr²h
V = π * 5.5² * 10 ≈ 950.33 ft³
The answer is thus 950.33 ft³.

when demand is , increases in price result in increases in total revenues, while decreases in price result in decreases in total revenue.group of answer choiceselasticcross-elasticflexibleinelastic
Answers
The answer is "inelastic". When demand is inelastic, changes in price do not significantly affect the quantity of goods or services demanded.
This means that increases in price result in increases in total revenue, while decreases in price result in decreases in total revenue. Inelastic demand occurs when consumers are not very responsive to changes in price and do not have good alternatives to the product or service being offered. Examples of products with inelastic demand are necessities like food, medicine, and gasoline, where consumers will continue to purchase the product regardless of price changes because they need it for daily living. On the other hand, products with elastic demand, like luxury items or non-essential goods, will see a significant decrease in demand when prices increase.

the pound is an english unit of measure; its si counterpart is the
Answers
The pound is an English unit of measure, primarily used for weight. Its SI counterpart is the kilogram. The kilogram is the base unit of mass in the International System of Units (SI). It is defined as the mass of the International Prototype of the Kilogram (IPK), a platinum-iridium cylinder kept at the International Bureau of Weights and Measures (BIPM) in France.
Unlike the pound, which can vary in its exact weight depending on the context, the kilogram is a standardized unit. This means that one kilogram is always equal to 1000 grams. The SI system is used internationally and provides a consistent and uniform way to measure mass.
For example, if you have a 5-pound bag of flour and want to know its weight in kilograms, you would convert it by dividing the pounds by 2.2046, since 1 pound is approximately 0.4536 kilograms. In this case, the 5-pound bag of flour would be approximately 2.2679 kilograms.
In summary, while the pound is an English unit of measure for weight, its SI counterpart is the kilogram. The kilogram is the base unit of mass in the SI system and provides a standardized and internationally recognized way to measure mass.

What are the surface area of a cuboid?A cuboid is a solid shape or a three-dimensional shape.
Surface area is the amount of space covering the outside of a three-dimensional shape.
The surface area of a cuboid is expressed as;
SA = 2( lb + lh + bh)
length = 1 2/5 = 7/5
breadth = 5/8
height = 3/8

Instead of rotating 20 degrees counterclockwise around the origin followed by rotating 80 degrees clockwise around the origin, we could simply rotate 60 degrees clockwise around the origin.
Can you find a simple description of reflecting across the x-axis followed by reflecting across the y-axis?
Answers
Answer:
We rotate the point counterclockwise by an angle θ = tan⁻¹ (y/x)
Step-by-step explanation:
If we have the point (x, y), its reflection along the x-axis (x,-y). The reflection of the point (x, -y) along the y - axis is (-x, -y). So, the angle between the initial point (x, y) and the final point (-x, -y) is θ = tan⁻¹ [(-y - y)/(- x -x)] = tan⁻¹ [(-2y/(-2x)] = tan⁻¹(y/x).
So, the point (x, y) is rotated counterclockwise by an angle of θ = tan⁻¹ (y/x) to perform both reflections.

Yasmine earns $11.75 per hour and works 35 hours per week. She has a young child and feel like she cannot spend more than 30% of her total income on rent. What is the maximum monthly rent that she should pay? Assume that she gets paid 4 times in one month. Round your answer to two decimal places.
Answers
The maximum monthly rent that Yasmine should pay is approximately $619.58.
To calculate the maximum monthly rent that Yasmine should pay, we need to determine her monthly income and then find 30% of that amount.
Yasmine's hourly = $11.75
Hours worked per week = 35
Weekly income = Hourly wage * Hours worked per week
= $11.75 * 35
= $411.25
Monthly income = Weekly income * Number of weeks in a month
= $411.25 * 4
= $1645
Now, let's calculate 30% of her monthly income:
Rent limit = 30% of Monthly income
= 0.30 * $1645
= $493.50
Therefore, the maximum monthly rent that Yasmine should pay is
To determine the maximum monthly rent that Yasmine can afford, we first calculate her monthly income. Since she earns $11.75 per hour and works 35 hours per week, we multiply her hourly wage by the number of hours worked per week to find her weekly income.
Next, we multiply her weekly income by the number of weeks in a month (which we assume to be 4) to obtain her monthly income.
Finally, we calculate 30% of her monthly income by multiplying it by 0.30, which represents 30% as a decimal.
The result, rounded to two decimal places, is the maximum monthly rent that Yasmine should pay. In this case, the maximum monthly rent is $493.50.

For each situation, determine the level of accuracy needed. Explain. You are estimating the height of a person. Which unit of measure should you use: 1 foot, 1 inch, or 1/16 inch?
Answers
The unit of measure to use when estimating the height of a person depends on the level of accuracy required for the specific situation.
When estimating the height of a person, the level of accuracy needed depends on the specific situation.
If you are estimating the height from a distance and only need a rough estimate, using 1 foot as the unit of measure would be sufficient. This is because 1 foot is a commonly used unit of measure for estimating human height.
If you need a slightly more accurate estimate, you can use 1 inch as the unit of measure.
This would provide a finer level of measurement and allow for more precise estimation.
However, if you require a highly accurate estimation, such as in medical or scientific contexts, using 1/16 inch as the unit of measure would be appropriate.
This is because 1/16 inch provides a much smaller increment for measurement and allows for a more precise estimation of height.
In summary, the unit of measure to use when estimating the height of a person depends on the level of accuracy required for the specific situation.

Answers
The missing values are:
BC = 25, BN = 16, NC = 9, and AN = 12
Given:
AB = 20
AC = 15
Using the Pythagorean theorem in triangle ABC:
CB = √AC² + AB²
CB= √20² + 15²
CB= √625
CB= 25
Since, AN is altitude we have ΔNBA~ΔABC and ΔNAC~ΔABC
BN / AN = BA / CB
BN/ 20= 20/25
BN = 16
and, AN / BA = AC / CB
AN /20 = 15/ 25
AN = 12
Now, CN= CB - BN
CN = 25- 16
CN= 9
BC^2 = 20^2 + 15^2
