The data from the stem-and-leaf plot is:
10,
24,25,26,
30,30,32,33,
40,45,46
Add up those values
10+24+25+26+30+30+32+33+40+45+46 = 341
Then divide over n = 11 which is the sample size.
341/11 = 31 is the arithmetic mean.

Ten mangos and twelve avocadoes cost $23. Five mangos and four avocadoes cost $10. How much do one mango and one avocado cost?
Answers
Answer:
$2.15
Step-by-step explanation:
Let mango be m
Let avocado be a
10m + 12a = 23
5m + 4a = 10
Let's get rid of the mangos in the second equation
10m + 12a = 23
-2 x (5m + 4a = 10)
Now we get:
10m + 12a =23
-10m -8a = -20
Add both the equations and we get:
4a = 3
a = $0.75
since we know that one avocado is for $0.75, we can use this value to find the cost of one mango.
5m + 4a = 10
5m + 4(0.75) = 10
5m + 3 = 10
5m = 7
m = 1.4
So, we now know that a mango cost $1.4
To find the cost of one mango and one avocado:
a + m = 0.75 + 1.4 = 2.15
Therefore, the cost of one mango and one avocado is $2.15
The required cost of one mango is 1.4 and cost of one avocado is 0.75.
What is an equation ?An equation is a combination of different variables, in which two mathematical expressions are equal to each other.
Given that,
Cost of ten mangos and twelve avocados is $23,
And cost of five mangos and four avocados is $10.
Let cost of mangoes be represented as M and cost of avocados be represented as A,
The equation can be written as,
10 M + 12 A = 23 (1)
5 M + 4 A = 10 (2)
By solving equation (1) and (2),
M = 7/5 = 1.4
N = 3/4 = 0.75
The cost of one mango is 1.4 and cost of one avocado is 0.75.

Use the Midpoint Rule with \(n=5\) to estimate the volume obtained by rotating about the y-axis the region under the curve \(y=\sqrt{1+x^3}\), \(0\leq x\leq 1\).
Answers
To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).
Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)
where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.
First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:
\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)
Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:
\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)
Now, we can calculate the approximate volume using the Midpoint Rule:
\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)
Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

x = a + b + 4
a ∝ y^2, b ∝ 1/y when x = 18, y = 2 and when x = -3, y = 1 then find x when y = 4.
TYVM!!
Answers
Answer:
81
Step-by-step explanation:
Given the relationships \(a \propto y^2\) and \(b \propto \frac{1}{y}\), let's solve for the proportionality constants and then use them to find \(x\) when \(y = 4\).
From the given values:
1. When \(x = 18\) and \(y = 2\), we have \(a + b + 4 = 18\).
2. When \(x = -3\) and \(y = 1\), we have \(a + b + 4 = -3\).
We can set up two equations using the given proportionalities and the given values:
Equation 1: \(a = ky^2\)
Equation 2: \(b = \frac{c}{y}\)
Substituting these into the first given condition:
\(ky^2 + \frac{c}{y} + 4 = 18\)
Substituting these into the second given condition:
\(ky^2 + \frac{c}{y} + 4 = -3\)
Solving these two equations will allow us to find the constants \(k\) and \(c\), and then we can use them to find \(x\) when \(y = 4\).
Let's solve the equations:
From the first equation:
\(k(2^2) + \frac{c}{2} + 4 = 18\)
\(4k + \frac{c}{2} + 4 = 18\)
\(4k + \frac{c}{2} = 14\)
From the second equation:
\(k(1^2) + \frac{c}{1} + 4 = -3\)
\(k + c + 4 = -3\)
\(k + c = -7\)
Now we have a system of two equations:
1. \(4k + \frac{c}{2} = 14\)
2. \(k + c = -7\)
Solve the second equation for \(k\): \(k = -c - 7\)
Substitute this into the first equation:
\(4(-c - 7) + \frac{c}{2} = 14\)
\(-4c - 28 + \frac{c}{2} = 14\)
\(-8c - 56 + c = 28\)
\(-7c = 84\)
\(c = -12\)
Substitute \(c\) back into \(k + c = -7\):
\(k - 12 = -7\)
\(k = 5\)
Now that we have \(k\) and \(c\), we can determine the values of \(a\) and \(b\) using the given proportionalities:
\(a = 5y^2\)
\(b = \frac{-12}{y}\)
Finally, substitute these values of \(a\), \(b\), and \(y\) into the equation \(x = a + b + 4\) to find \(x\) when \(y = 4\):
\(x = 5(4^2) + \frac{-12}{4} + 4\)
\(x = 80 - 3 + 4\)
\(x = 81\)
So, when \(y = 4\), \(x\) is 81.

Given :
Ed's string length = 21.72 inches
Georgiana's string length = 1/6 of Ed's string length
To Find :
Georgiana's string length
Solving :
Georgiana's string length = 1/6 of Ed's string length
Georgiana's string length = 1/6 × 21.72
Georgiana's string length = 21.72/6
Georgiana's string length = 3.62 inches
Answer:
3.62 inches
Step-by-step explanation:
Step-by-step explanation:
Given that Ed's string length is = 21.72 inches
And that Georgiana's string length is = 1/6 of Ed's string length
We need to find Georgiana's string length
Georgiana's string length = 1/6 of Ed's string length
And Georgiana's string length = 1/6 × 21.72
Georgiana's string length = 21.72/6
Which would bring us that Georgiana's string length is = 3.62 inches

Answers
Answer:

Step-by-step explanation:
You want the total surface area of the pentagonal prism shown.
Base areaThe area of each of the two pentagonal bases is the sum of the area of the yellow rectangle and the area of the triangle above it. That sum is ...
A = LW +1/2bh
A = 5(12) +1/2(12)(9) = 12(5 +9/2) = 114 . . . . square inches
Lateral areaThe lateral area of the prism is the sum of the areas of the 5 rectangles. That sum will be the product of the perimeter of the pentagonal base and the distance between bases.
LA = (12 +5 +11 +11 +5)(20) = (44)(20) = 880 . . . . square inches
Total areaThe total surface area of the figure is the sum of the two base areas and the lateral area:
SA = 2(114 in²) +880 in² = 1108 in²
The surface area of the composite figure is 1108 in².

Answers
Answer:
C. 8(1)=8(−4+3/8x)
Step-by-step explanation:
Given equation
1=−4+3/8x
in this equation in denominator we have 8x,
since we are solving for x we cannot eliminate it, but we have to eliminate 8 in denominator, so that there only numerator in equation and solving process becomes easier.
To eliminate 8,we need to multiply both side by 8, so as to balance the equation and also 8 from denominator gets cancelled in RHS.
1=−4+3/8x
multiply both side by 8
8(1)=8(−4+3/8x)
Thus, option c is correct one
8(1)=8(−4+3/8x)
solving it
8 = -32 + 3/x
adding both side 32
8+32 = -32 + 3/x -32
=> 40 = 3/x
=> x = 3/40
