Find the sample size needed to estimate the percentage of adults who can wiggle their ears. Use a margin of error of 5 percentage points and use a confidence level of 90%
Complete parts (a) and (b) below.
b. Assume that 23% of adults can wiggle their ears.
n
(Round up to the nearest integer.)
.
The sample size for the part (a) is 269, and the sample size for part (b) is 191 if a margin of error of 5 percentage points and use a confidence level of 90%
What is the margin of error(MOE)?It is defined as an error that gives an idea about the percentage of errors that exist in the real statistical data.
The formula for finding the MOE:
[tex]\rm MOE = Z{score}\times\frac{s}{\sqrt{n} }[/tex]
Where is the z score at the confidence interval
s is the standard deviation
n is the number of samples.
We have:
MOE = 5% = 0.05 and
[tex]\alpha = 1-0.9 \Rightarrow 0.1[/tex]
Let's assume the value of p = 0.5, and q = 0.5
From the table:
[tex]\rm Z_{\alpha/2}\Rightarrow Z_{0.1/2}\Rightarrow Z_{0.05}\Rightarrow 1.64[/tex]
[tex]\rm n = p\times q \frac{Z^2_{\alpha/2}}{MOE^2}[/tex]
[tex]\rm n = 0.5\times 0.5\frac{1.64^2}{0.05^2}[/tex]
n = 268.96 ≈ 269
For part(b)
The value of p = 0.23, and q = 0.77
From the table:
[tex]\rm Z_{\alpha/2}\Rightarrow Z_{0.1/2}\Rightarrow Z_{0.05}\Rightarrow 1.64[/tex]
[tex]\rm n = p\times q \frac{Z^2_{\alpha/2}}{MOE^2}[/tex]
[tex]\rm n = 0.23\times 0.77\frac{1.64^2}{0.05^2}[/tex]
n = 190.53 ≈ 191
Thus, the sample size for the part (a) is 269, and the sample size for part (b) is 191 if a margin of error of 5 percentage points and use a confidence level of 90%

Determine the volume of cone. Use 3.14 for pi.
Answer:
[tex]V_{cone}\approx366.33\: cm^3[/tex]
Step-by-step explanation:
Here,
Height of cone (h) = 14 m
Radius of cone (r) = 5 m
[tex]V_{cone}= \frac{1}{3}\pi r^2 h[/tex]
Plugging in the values of h and r in the above formula, we find:

K=100-4n
What is value of n when k =99
Answer:
The value of n = 1/4
Step-by-step explanation:
Given : the value of k = 99
K=100-4n ..i)
putting the value of k = 99 in equation ..i)
=> 99 = 100 -4n
=> 99 -100 = -4n
=> -1 = -4n
=> 1/4 = n
Answer:
K = -296
Step-by-step explanation:
K = 100 - 4n
K = 100 - 4(99)
K = 100 - 396
K = -296

If one cylinder is r=3 ft and the volume is 756 feet cubed, how do I find the volume of a larger cylinder with a radius of 7feet?
Answer:
[tex]4116\; {\rm ft^{3}}[/tex], assuming that the two cylinders are of the same height.
Step-by-step explanation:
The volume of a cylinder of radius [tex]r[/tex] and height [tex]h[/tex] is [tex]\pi\, r^{2}\, h[/tex].
If the two cylinders are of the same height [tex]h[/tex], the volume of the two cylinders would be proportional to the square of their radii.
Let [tex]r_{0}[/tex] and [tex]V_{0}[/tex] denote the radius and volume of the smaller cylinder. Similarly, let [tex]r_{1}[/tex] and [tex]V_{1}[/tex] denote the radius and volume of the larger cylinder. Assuming that the height of both cylinders is [tex]h[/tex]:
[tex]V_{1} = \pi\, {r_{1}}^{2}\, h[/tex].
[tex]V_{0} = \pi\, {r_{0}}^{2}\, h[/tex].
Hence, [tex](V_{1}) / (V_{0})[/tex] (ratio between the volume of the larger cylinder and the volume of the smaller cylinder) would be:
[tex]\begin{aligned}\frac{V_{1}}{V_{0}} &= \frac{\pi\, {r_{1}}^{2}\, h}{\pi\, {r_{0}}^{2}\, h} =\frac{{r_{1}}^{2}}{{r_{0}}^{2}}\end{aligned}[/tex].
In this question, it is given that:
the volume of the smaller cylinder is [tex]V_{0} = 756\; {\rm ft^{3}}[/tex].the radius of the smaller cylinder is [tex]r_{0} = 3\; {\rm ft}[/tex].the radius of the larger cylinder is [tex]r_{1} = 7\; {\rm ft}[/tex].Rearrange the equation [tex]\begin{aligned}\frac{V_{1}}{V_{0}} &= \frac{{r_{1}}^{2}}{{r_{0}}^{2}}\end{aligned}[/tex] to find an expression for [tex]V_{1}[/tex], volume of the larger cylinder:
[tex]\begin{aligned}V_{1} &= \frac{{r_{1}}^{2}\, V_{0} }{{r_{0}}^{2}} \\ &= \frac{{(7\; {\rm ft})}^{2}}{{(3\; {\rm ft})}^{2}} \times (756\; {\rm ft^{3}}) \\ &= 4116\; {\rm ft^{3}} \end{aligned}[/tex].

12a+7c=315
how to solve for/what is a?
Answer:
Well I mean There are multiple solutions I think, a = 26.25
Step-by-step explanation:
Simplifying
12a + 7c = 315
Solving
12a + 7c = 315
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Add '-7c' to each side of the equation.
12a + 7c + -7c = 315 + -7c
Combine like terms: 7c + -7c = 0
12a + 0 = 315 + -7c
12a = 315 + -7c
Divide each side by '12'.
a = 26.25 + -0.5833333333c
Simplifying
a = 26.25 + -0.5833333333c
[tex]12a+7c=315\\\\\implies 12a = 315-7c\\\\\implies a = \dfrac{315-7c}{12}\\\\\implies a = \dfrac{7}{12}(45-c)[/tex]
Compute the NPV for Project M if the appropriate cost of capital is 7 percent
Based on the cashflow of Project M and its appropriate cost of capital, the NPV can be calculated to be $465.92.
What is the NPV of Project M?The NPV is the present value of the cash inflows less the present value of the cash outflows.
= ∑ (Cash inflow / (1 + cost of capital) ^ year of inflow) - Cost outflow
Solving gives:

Answer:
x = 5
Step-by-step explanation:
70 - 4x = 30 + 4x
Add 4x on both sides of the equation,
70 - 4x + 4x = 30 + 4x + 4x
70 = 30 + 8x
Subtract 30 from both sides of the equation to isolate 8x,
70 - 30 = 30 + 8x - 30
40 = 8x
Divide both sides of the equation by 8 to solve for x,
40 ÷ 8 = 8x ÷ 8

he table below represents an exponential function, g, that has been vertically shifted from the parent function, f(x) = 2x. x 0 1 2 3 4 g(x) -11 -10 -8 -4 4 Determine the size of the shift from function f to function g. Then, plot the points of a function that is shifted only half as much as g from the parent function, f. Use the same x-values as used in the table for function g.
Answer:
1. The size of shift from function f to function g is -12
2. The plot of the points of a function that is shifted only half as much as g from the parent function f is in the attached file in blue color.
Step-by-step explanation:
Parent function: f(x)=2^x
x=0→f(0)=2^0→f(0)=1
x=1→f(1)=2^1→f(1)=2
x=2→f(2)=2^2→f(2)=4
x=3→f(3)=2^3→f(3)=8
x=4→f(4)=2^4→f(4)=16
Size of the shift from function f to function g: s
s=g(0)-f(0)=-11-1→s=-12
s=g(1)-f(1)=-10-2→s=-12
s=g(2)-f(2)=-8-4→s=-12
s=g(3)-f(3)=-4-8→s=-12
s=g(4)-f(4)=4-16→s=-12

Answer:
48 square units
Step-by-step explanation:
area of triangle = base * height / 2
base = x+1
height = 8x
area = (x+1)(8x)/2 = (8x²+8x)/2 = 4x²+4x
area of rectangle = length * width = (5x+1)(x) = 5x²+x
set the two areas to be equal to each other
5x²+x = 4x²+4x
divide both sides by x as that is a multiple of each value on each side
5x + 1 = 4x + 4
subtract 4x from both sides to limit the variable to one side
x + 1 = 4
subtract both sides by 1 to isolate the variable
x = 3
area = (5x+1)(x) = (5*3+1)(3) = 16 * 3 = 48 square units
