Please calculate the volume of a solid oblique pyramid with a triangular base, given that the base has a length of 8 inches and a height of 6 inches, and the height of the pyramid is 10 inches. Round your answer to the nearest cubic inch.
Answer: 74
Step-by-step explanation:
The volume of the pyramid can be found using the formula:
Volume = (1/3) x Base Area x Height
To find the base area, we need to find the area of the triangular base. The area of a triangle can be found using the formula:
Area = (1/2) x Base x Height
Substituting the given values, we have:
Area = (1/2) x 8 x 6 = 24 square inches
To find the height of the pyramid, we can use the Pythagorean theorem. The slant height and one-half of the base form a right triangle, so we have:
Height^2 = (Slant Height)^2 - (1/2 x Base)^2
Height^2 = 10^2 - 4^2
Height^2 = 84
Height = √84 ≈ 9.165 inches
Now we can substitute the values into the formula for the volume:
Volume = (1/3) x Base Area x Height
Volume = (1/3) x 24 x 9.165
Volume ≈ 73.96 cubic inches
Therefore, the volume of the pyramid is approximately 73.96 cubic inches.Step-by-step explanation:

Answer:
(Sumita plans to deposit Rs. 21000 in any bank for 3 years. (a) Define compound interest. (b) How much amount will she get at 10% simple interest when she deposits it in a bank N ? Calculate it. (c) How much amount will she get at 9% interest being compounded annually when she deposits it in another bank M?Calculate it. (d) Which bank is better to deposit the sum and how much more amount will she get (e) from the bet
(a) Compound interest is the interest earned on both the initial principal amount and any accumulated interest from previous periods. Unlike simple interest, which is calculated only on the principal amount, compound interest takes into account the interest that has been added to the principal over time.
(b) To calculate the amount Sumita will get at 10% simple interest when she deposits Rs. 21,000 in bank N for 3 years, we can use the formula for simple interest:
Simple Interest = (Principal * Rate * Time) / 100
In this case:
Principal (P) = Rs. 21,000
Rate of interest (R) = 10%
Time (T) = 3 years
Simple Interest = (21,000 * 10 * 3) / 100
Simple Interest = 6,300
Amount = Principal + Simple Interest
Amount = 21,000 + 6,300
Amount = Rs. 27,300
Therefore, Sumita will get Rs. 27,300 at 10% simple interest when she deposits it in bank N.
(c) To calculate the amount Sumita will get at 9% interest compounded annually when she deposits Rs. 21,000 in bank M for 3 years, we can use the formula for compound interest:
Compound Interest = Principal * [(1 + Rate/100) ^ Time] - Principal
In this case:
Principal (P) = Rs. 21,000
Rate of interest (R) = 9%
Time (T) = 3 years
Compound Interest = 21,000 * [(1 + 9/100) ^ 3] - 21,000
Calculating the compound interest:
Compound Interest = 21,000 * (1.09^3) - 21,000
Compound Interest ≈ 21,000 * 1.29503 - 21,000
Compound Interest ≈ 27,139.63 - 21,000
Compound Interest ≈ Rs. 6,139.63
Amount = Principal + Compound Interest
Amount = 21,000 + 6,139.63
Amount ≈ Rs. 27,139.63
Therefore, Sumita will get approximately Rs. 27,139.63 at 9% interest compounded annually when she deposits it in bank M.
(d) To determine which bank is better to deposit the sum, we compare the amounts received in bank N (simple interest) and bank M (compound interest).
In bank N, Sumita will receive Rs. 27,300, while in bank M, she will receive approximately Rs. 27,139.63.
Comparing the amounts, we can see that Sumita will get a slightly higher amount in bank N.
(e) The amount she will get from the better bank (bank N) is Rs. 27,300 - Rs. 27,139.63 = Rs. 160.37 more than bank M.

Data was collected for 300 fish from the North Atlantic. The length of the fish (in mm) is summarized in the GFDT below
Part 1- The lower class boundary for the first class is 100.
Part 2- Approximately 75% of students take exactly two courses.
Part 1:
To find the lower class boundary for the first class, we need to consider the given class intervals. The lower class boundary is the smallest value within each class interval.
Given the class intervals:
100 - 104
105 - 109
110 - 114
115 - 119
120 - 124
125 - 129
130 - 134
The lower class boundary for the first class interval (100 - 104) would be 100.
So, the lower class boundary for the first class is 100.
Part 2:
To determine the percentage of students who take exactly two courses, we need to calculate the relative frequency for that particular category.
Given the data:
of Courses Frequency Relative Frequency Cumulative Frequency
1 23 0.4423 23
2 - 39
3 13 0.25 -
We can see that the cumulative frequency for the second class (2 courses) is 39. To find the relative frequency for this class, we need to divide the frequency by the total number of students surveyed, which is 52.
Relative Frequency = Frequency / Total Number of Students
Relative Frequency for 2 courses = 39 / 52 ≈ 0.75 (rounded to 4 decimal places)
To convert this to a percentage, we multiply the relative frequency by 100.
Percentage of students taking exactly two courses = 0.75 * 100 ≈ 75%
Therefore, approximately 75% of students take exactly two courses.

What is the solution for t in the equation?
2/3t-1/5t=2
Answer:
Step-by-step explanation:
To solve the equation (2/3)t - (1/5)t = 2 for t, we need to combine like terms and isolate the variable t. Here are the steps:
(2/3)t - (1/5)t = 2
To combine the fractions, we need to find a common denominator for 3 and 5, which is 15.
[(2/3)(5/5)]t - [(1/5)(3/3)]t = 2
(10/15)t - (3/15)t = 2
[(10 - 3)/15]t = 2
(7/15)t = 2
To isolate t, we can multiply both sides of the equation by the reciprocal of (7/15), which is (15/7).
[(7/15)t][(15/7)] = 2[(15/7)]
t = (2 * 15) / 7
t = 30/7
Therefore, the solution for t in the equation (2/3)t - (1/5)t = 2 is t = 30/7 or t ≈ 4.286.

(a) The sum of the series 1+2+3+4+...+392 is 77,028.
(b) The sum of the series 1+2+3+4...x is (x/2)(1 + x).
(c) The sum of the series 546 + 547 + 548 + 549 is 2,190.
To solve the exercise using Polya's four-step problem-solving strategy, we will apply the procedures presented in the lesson.
(a) For the series 1+2+3+4+...+392:
Using the arithmetic series formula Sn = (n/2)(a + l), where n is the number of terms, a is the first term, and l is the last term, we can substitute the values: Sn = (392/2)(1 + 392) = 196(393) = 77,028.
(b) For the series 1+2+3+4...x:
To find the sum of this series, we need to know the number of terms (n) based on the value of x. Since the series follows a consecutive pattern, the number of terms will be equal to x itself. Thus, the sum of the series would be Sn = (x/2)(1 + x).
(c) For the series 546 + 547 + 548 + 549:
Using the arithmetic series formula Sn = (n/2)(a + l), we can determine the number of terms (n) by subtracting 546 from 549 and then adding 1: n = 549 - 546 + 1 = 4. Substituting the values into the formula: Sn = (4/2)(546 + 549) = 2(1095) = 2,190.
The final answer for each part is:
(a) The sum of the series 1+2+3+4+...+392 is 77,028.
(b) The sum of the series 1+2+3+4...x is (x/2)(1 + x).

point slope form (0,12), (-6,0)
This is the equation of the line in point-slope form, where the slope is 2 and the given point is (0, 12).
To find the equation of a line in point-slope form, we need a point on the line and the slope of the line.
Given the points (0, 12) and (-6, 0), we can calculate the slope using the formula:
slope = (y2 - y1) / (x2 - x1)
Using the coordinates (0, 12) as (x1, y1) and (-6, 0) as (x2, y2):
slope = (0 - 12) / (-6 - 0)
slope = -12 / -6
slope = 2
Now that we have the slope, we can use the point-slope form of the equation:
y - y1 = m(x - x1)
Using the point (0, 12) as (x1, y1) and the slope (m) as 2:
y - 12 = 2(x - 0)
Simplifying the equation:
y - 12 = 2x
This is the equation of the line in point-slope form, where the slope is 2 and the given point is (0, 12).

The hip width x of adult females is normally distributed with a mean of 37.6 cm and a standard deviation of 4.36 cm. The maximum width of an aircraft seat that will accommodate 98% of all adult women is about: (Give your answer to one decimal places if necessary.)
Answer:
Step-by-step explanation:
To find the maximum width of an aircraft seat that will accommodate 98% of all adult women, we need to determine the corresponding z-score for the 98th percentile of the normal distribution.
First, we find the z-score corresponding to the 98th percentile using a standard normal distribution table or calculator. The z-score for the 98th percentile is approximately 2.05.
Next, we use the z-score formula to find the corresponding value in the original distribution:
z = (x - μ) / σ
Solving for x (the maximum width of the aircraft seat):
x = z * σ + μ
Substituting the values given:
x = 2.05 * 4.36 + 37.6
x ≈ 45.98
Therefore, the maximum width of an aircraft seat that will accommodate 98% of all adult women is approximately 46 cm (rounded to one decimal place).

Let's assign variables to represent the cost of a calculator and the cost of a pen.
Let c represent the cost of a calculator.
Let p represent the cost of a pen.
Based on the given information, we can form the following pair of simultaneous equations:
Equation 1: 4c + 2p = 20.60 (Mia buys 4 calculators and 2 pens for $20.60)
Equation 2: 5c + 3p = 26.90 (Heidi buys 5 calculators and 3 pens for $26.90)
To solve for the cost of a pen, we'll eliminate the variable c by multiplying Equation 1 by 5 and Equation 2 by 4. Then we'll subtract Equation 1 from Equation 2:
5 * (4c + 2p) = 5 * 20.60
4 * (5c + 3p) = 4 * 26.90
20c + 10p = 103.00
20c + 12p = 107.60
Subtracting Equation 1 from Equation 2:
(20c + 12p) - (20c + 10p) = 107.60 - 103.00
20c - 20c + 12p - 10p = 4.60
2p = 4.60
p = 4.60 / 2
p = 2.30
Therefore, the cost of a pen is $2.30.
Answer:
Let's assume that the cost of a calculator is x and the cost of a pen is y. Then we can write the following pair of equations:
4x + 2y = 20.60 (equation 1)
5x + 3y = 26.90 (equation 2)
To solve for the cost of a pen, we need to eliminate x from the equations. We can do this by multiplying equation 1 by 5 and equation 2 by -4, and then adding them:
(5)(4x + 2y = 20.60) becomes 20x + 10y = 103 (equation 3)
(-4)(5x + 3y = 26.90) becomes -20x - 12y = -107.60 (equation 4)
Adding Equation 3 and Equation 4 gives:
-2y = -4.60
Divide both sides by -2:
y = 2.30
Therefore, the cost of a pen is $2.30.

MARK ME BRAINLIST
in this chart, × is the length of a persons forearm in centimeters and y is the persons height in centimeters. the question is if someones forearm (x) is 24.5 cm, how tall would they be? how do i find this? and how would i make a linear regression graph? thanks
The height of a person whose length of forearm is 24.5 cm is equal to 163.38 centimeters.
How to construct and plot the data in a scatter plot?In this exercise, we would plot the length of forearm on the x-axis of a scatter plot while height would be plotted on the y-axis of the scatter plot through the use of Microsoft Excel.
On the Microsoft Excel worksheet, you should right click on any data point on the scatter plot, select format trend line, and then tick the box to display a linear equation for the line of best fit on the scatter plot;
y = 3.01x + 89.63
Based on the equation of the line of best fit above, the height of a person whose length of forearm is 24.5 cm can be determined as follows;
y = 3.01x + 89.63
y = 3.01(24.5) + 89.63
y = 163.375 ≈ 163.38 centimeters.
