Approximate the area under the function between a and b using a right-hand sum with the given number of intervals.
f(x) = 4 - x^2
a = 0, b = 2
4 Intervals.
Answers
The approximate area under the curve of f(x) from x=0 to x=2 using a right-hand sum with four intervals is 4.25.
To approximate the area under the curve of the function f(x) = 4 - x^2 from x=0 to x=2 using a right-hand sum with four intervals, we first need to divide the interval [0, 2] into four equal subintervals of length h = (b-a)/n = (2-0)/4 = 0.5. The four subintervals are [0, 0.5], [0.5, 1], [1, 1.5], and [1.5, 2].
Next, we find the height of the curve at the right endpoint of each subinterval and multiply it by the width of the subinterval to get the area of the rectangle that approximates the region under the curve. Using the right endpoints of the subintervals, we have:
f(0.5) = 4 - (0.5)^2 = 3.75
f(1) = 4 - (1)^2 = 3
f(1.5) = 4 - (1.5)^2 = 1.75
f(2) = 4 - (2)^2 = 0
area of each rectangle:
A1 = f(0.5) * h = 3.75 * 0.5 = 1.875
A2 = f(1) * h = 3 * 0.5 = 1.5
A3 = f(1.5) * h = 1.75 * 0.5 = 0.875
A4 = f(2) * h = 0 * 0.5 = 0
the approximate area under the curve of f(x) from x=0 to x=2:
A ≈ A1 + A2 + A3 + A4 = 1.875 + 1.5 + 0.875 + 0 = 4.25

Rectangular prism with base of 4 cm by 3 cm and a height of 5 cm. Square pyramid with a base of 4 cm by 3 cm and a height of 5 cm.
What is the volume of the prism?
What is the volume of the pyramid?
Answers
Answer: A = 15cm squared
Step-by-step explanation:
I think :)
Given that the base of the prism is 4 cm by 3 cm and the height is 5 cm, the volume can be calculated as:
The volume of the prism = (length x width x height)
By applying the given values:
Volume of prism = 4 cm x 3 cm x 5 cm
The volume of the prism = 60 cubic cm
That implies the volume of the rectangular prism is 60 cubic cm.
We know that the pyramid's base measures 4 by 3 cm and its height is 5 cm, the base's area may be calculated as follows:
Area of base = length x width
Area of base = 4 cm x 3 cm
Area of base = 12 square cm
The volume of the pyramid can now be calculated as:
Volume of pyramid = (area of base x height) / 3
Volume of pyramid = (12 square cm x 5 cm) / 3
The volume of the pyramid = 20 cubic cm
Therefore, the volume of the square pyramid is 20 cubic cm.

A very good poker player is expected to earn $1 per hand in $100/$200 Texas poker Hold'em. The standard deviation is approximately $31.
a) What is the probability of a very good poker player earns a profit(more than $0) after playing 40 hands in $100/$200 Texas Hold'em?
b) What proportion of the time can a very good poker player expect to earn at least $500 after playing 100 hands in $100/$200 Texas Hold'em.
c) Suppose that twenty hands are played per hour. What is the probability that a very good poker player earns a profit during a 14 hour session?
Answers
a) The probability of a very good poker player earning a profit (more than $0) after playing 40 hands in $100/$200 Texas Hold'em can be calculated using the normal distribution and the given mean ($1) and standard deviation ($31). b) The proportion of the time a very good poker player can expect to earn at least $500 after playing 100 hands in $100/$200 Texas Hold'em can be calculated using the normal distribution and the given mean ($1) and standard deviation ($31).
To compute these probabilities, we need to make some assumptions and use probability distribution calculations based on the given information.
a) To determine the probability of a profit after playing 40 hands, we can use the concept of the normal distribution. We need to calculate the z-score using the formula: z = (x - μ) / σ, where x is the desired profit, μ is the expected profit per hand, and σ is the standard deviation. In this case, x = $0, μ = $1, and σ = $31.
Once we have the z-score, we can use a standard normal distribution table or calculator to find the corresponding probability.
b) Similarly, to find the proportion of the time a player can expect to earn at least $500 after playing 100 hands, we need to calculate the z-score for x = $500, using the same formula as in part (a). Then, we can use the standard normal distribution table or calculator to find the corresponding proportion.
c) To determine the probability of earning a profit during a 14-hour session, we need to calculate the number of hands played, which is 20 hands per hour multiplied by 14 hours. Let's denote it as N. Then, we can calculate the mean profit for the 14-hour session by multiplying the expected profit per hand ($1) by N.
The standard deviation for the session can be calculated by multiplying the standard deviation per hand ($31) by the square root of N. Finally, we can use the normal distribution and the same z-score calculation as in part (a) to find the probability.
Please note that the above calculations assume that the profits from each hand are independent and follow a normal distribution. Real poker outcomes may deviate from these assumptions.

Answers
Answer:
Step-by-step explanation:
The correct answer is: The median of 14 is the most accurate to use, since the data is skewed.
Explanation: Since the data is skewed to the right, meaning there are some larger donations that pull the mean up, the median is a more accurate measure of center. It represents the middle value of the data when it is ordered from smallest to largest, and is not affected by extreme values.
The correct answer is: The IQR is the best measure of variability, and it equals 3.
Explanation: The IQR (interquartile range) is the best measure of variability for this data because it shows the range of the middle 50% of the data. The range, which is the difference between the minimum and maximum values, is affected by outliers and extreme values. In this case, the IQR is equal to 20-17=3.
The correct answer is: There is an outlier at 22.
Explanation: To determine if there are outliers in the data, we can use the rule: an outlier is any value more than 1.5 times the IQR below the first quartile or above the third quartile. The first quartile is 9.5 and the third quartile is 18, so the IQR is 18-9.5=8.5. Therefore, any value less than 9.5-1.5(8.5)= -4.25 or greater than 18+1.5(8.5)=30.25 would be considered an outlier. The value of 22 is greater than 30.25, so it is an outlier.
The correct answer is: The IQR is the best measure of variability, and it equals 18.5.
Explanation: The IQR (interquartile range) is the best measure of variability for this data because it shows the range of the middle 50% of the data. The range, which is the difference between the minimum and maximum values, is affected by outliers and extreme values. In this case, the IQR is equal to the difference between the third quartile (25) and the first quartile (6.5), which is 18.5.
The correct answer is: Player A is the most consistent, with an IQR of 1.5.
Explanation: The IQR (interquartile range) is the best measure of variability for this data because it shows the range of the middle 50% of the data. To find the IQR, we first need to find the first and third quartiles. For Player A, the first quartile is 2 and the third quartile is 3, so the IQR is 3-2=1. For Player B, the first quartile is 2 and the third quartile is 5, so the IQR is 5-2=3.
The correct answer is: The median is the best measure of center, and it equals 7.3.
Explanation: Since the data is not strongly skewed, either the mean or the median could be used as a measure of center. However, the median is often preferred because it is less affected by extreme values. The median for this data is the value that is in the middle when the data is ordered from smallest to largest. In this case, we have 10 data points, so the median is the average of the 5th and 6th values, which are both equal to 7. Therefore, the median is 7, and not 7.3. The mean is also 7.3, but it is affected by the extreme values.

Question 1
The median of 14 is the most accurate to use, since the data is skewed.

Step-by-step explanation:
Answer:
139.27 meters squared
Step-by-step explanation:
So what you're doing is calculating the square's area and half of the circle's area.
The square's area is 100m^2 since 10*10=100
For the circle part, you use πr^2. You know the diameter of the circle, and radius is half of the diameter, so 10/2=5.
π*5^2 = 78.54 m^2
Since you have half of a circle you divide this by 2.
39.27
Finally you add your two areas together
100+39.27=139.27 meters ^2

Answers
Solution:
Given:
where;
\(\begin{gathered} l=20ft \\ h=16ft \end{gathered}\)A right triangle can be extracted from the image above,
Applying the Pythagoras theorem to the right triangle,
\(\begin{gathered} \text{hypotenuse}^2=\text{opposite}^2+\text{adjacent}^2 \\ \\ \text{Thus,} \\ l^2=h^2+w^2 \end{gathered}\)To find w, substitute the known values into the formula,
\(\begin{gathered} l^2=h^2+w^2 \\ 20^2=16^2+w^2 \\ 400=256+w^2 \\ 400-256=w^2 \\ 144=w^2 \\ w=\sqrt[]{144} \\ w=\pm12 \\ Si\text{nce the problem is on the distance to hold the base of the ladder, we pick the positive value only.} \\ \text{Thus,} \\ w=12ft \end{gathered}\)Therefore, the distance from the wall that the base of the ladder should be while they climb back in is 12 feet.
Hence, option D is the correct answer.
