given that 133 base n = 43base 10, find the value of n
Answer:
n = 5
Step-by-step explanation:
Any 3-digit number to the base n will have its rightmost digit have a place value of n⁰, its next rightmost digit a place value of n¹ and the leftmost digit will have a place value of n²
This means 133can be represented as follows
n² n¹ n⁰
1 3 3
The actual value in terms of a base of 10
= 3 x n⁰ + 3 x n¹ + 1 x n²
= 3 x 1 + 3 x n + 1 x n² (n⁰ = 1 and n¹ = n)
= 3 + 3n + 1n²
Since we are given the information that 133ₙ = 43₁₀
3 + 3n + 1n² = 43
subtract 3 from both sides
3n + 1n² = 40
Rewrite as
n² + 3n = 40
Factoring n on the left side=>
n(n + 3) = 40
If we look at the factors of 40:
1 x 40
2 x 20
4 x 10
5 x 8
5 and 8 satisfy the condition n(n + 3) = 40
So n = 5

5. suppose f is continuously complex differentiable on ω, and t ⊂ ω is a triangle whose interior is also contained in ω. apply green’s theorem to show that ???? this provides a proof of goursat’s theorem under the additional assumption that f′ is continuous.
The most appropriate choice for Green's Theorem, Cauchy Riemann Equation and Cauchy Goursat Theorem will be given by-
Cauchy Goursat Theorem has been proved using Green's Theorem-
What is Green's Theorem, Cauchy Riemann Equation and Cauchy Goursat Theorem?
Green's Theorem
Let C be a positively oriented, piecewise smooth, simple closed curve in a plane, and let D be the region bounded by C. Then
Green's Theorem states that
[tex]\int_c (Mdx + Ndy)=\int_D(M_x - N_y)dxdy[/tex]
M and N are functions of x and y
Cauchy Goursat Theorem
If a function f is analytic at all points interior to and on a simple closed contour C, then
[tex]\int_c f(z) dz = 0[/tex]
Cauchy Riemann Equation
If [tex]f(z)=u(x,y) + i v(x,y)[/tex] is analytic at z = x + iy then Cauchy Riemann Equation states that
[tex]u_x = v_y, u_y = -v_x[/tex]
Here,
Let [tex]f(z) = U(x,y) + iV(x,y)[/tex]
[tex]U, V, x, y[/tex] are continuous
[tex]f(z)dz = (U + i V)(dx + i dy)[/tex]
[tex]f(z) dz = (U dx - Vdy)+i(Vdx + Udy)[/tex]
[tex]\int_c f(z) dz = \int_c(U dx - Vdy)+i\int_c(Vdx + Udy)[/tex], C is the curve
By Green's Theorem,
[tex]\int_c f(z)dz = \int_D(U_ydydx - V_xdxdy)+i\int_D(U_xdxdy + V_ydydx)[/tex], D is the surface
[tex]\int_c f(z)dz = \int_D(-U_y - V_x)dxdy+i\int_D(U_x - V_y)dxdy[/tex][tex]\int_c f(z)dz = \int_D(V_x - V_x)dxdy+i\int_D(U_x - U_x)dxdy[/tex]
Since [tex]f'[/tex] is continuous, [tex]f[/tex] is analytic
So [tex]f[/tex] satisfies Cauchy Riemann equation
[tex]U_x = V_y, U_y = -V_x[/tex]
So,
[tex]\int_c f(z)dz = \int_D(V_x - V_x)dxdy+i\int_D(U_x - U_x)dxdy[/tex]
[tex]\int_c f(z)dz = 0[/tex]

among 6 electrical components exactly one is known not to function properly. if 4 components are randomly selected, find the probability that at least one does not function properly.
The probability that at least one electrical components does not function properly is 83.3%
What is defined as the probability?Probability is simply the likelihood of something occurring.When we are uncertain about the result of an event, we can discuss the probabilities of various outcomes—how probably they are.To make the calculation easier, use the following property:
P(at the very least one) = 1 - P (None)
The total number of electrical components is 6.
Number that which not work well: 1
Number that works well: 5
We have options for selecting 4 good components from a set of 5 by;
⁵C₄ = 5
We have 4 options from a total of 6 components by;
⁶C₄ = 6
We have a way to do this if everything works properly; ¹C₀ = 1
P(at the very least one) = ⁵C₄× ¹C₀ /⁶C₄
P(at the very least one) = 5 / 6
P(at least one) = 0.833 = 83.3%
Thus, the probability that at least one of the electrical component will not function is 83.3%.

What percent of the variation in the number of bags of trash collected can be
explained by differences in the number of volunteers? (Only state the number of the
percent in the answer blank, do not include the % in the answer blank, as the
computer already knows it is a percentage)
Differences with in number of volunteers can explain 60.01% of the variation in the amount of trash bags collected.
What is termed as the correlation coefficient?In a correlation analysis, the correlation coefficient is indeed the direct measurement that quantifies the strength of a linear relationship between two variables. In a correlation report, the coefficient is represented by the letter r.The coefficient of correlation (r) between both the number of volunteers x and also the number of trash bags collected y is 0.775.
To calculate the percentage of variation for one derivative contract by the other, simply square the correlation coefficient.
Here, r = 0.775
Squaring both side.
r² = 0.775²
r² = 0.600625
Simply multiply with 100 to get the percent.
r² = 60.0625
r² = 60.01
Thus, differences in the number of volunteers can explain 60.01% of the variation in the number of trash bags collected.

The remaining number of socks S a store has is modeled
by S(p) = 14 - 2p, where p is the number of pairs of
socks sold.
A. What do S(0) and S(6) represent?
Considering the numeric values of the function, we have that:
a) S(0) represents the remaining number of socks after 0 pairs are sold, and S(6) represents the remaining number of socks after 6 pairs are sold.
b) S(0) = 14, S(6) = 12.
c) The domain is not all real numbers, as the remaining number of socks cannot be negative, hence the domain is of 0 ≤ p ≤ 7.
How to find the numeric value of a function or of an expression?To find the numeric value of a function, we replace each instance of the variable in the function by the desired value.
For this problem, the function is given as follows:
S(p) = 14 - 2p.
In which S(p) is the remaining number of socks after p socks are sold.
Then the numeric values are:
S(0) = 14 - 2(0) = 14.S(6) = 14 - 2(6) = 2.The domain of a function is the set that contains all possible input values of the function. The remaining number of socks cannot be negative, hence the domain is of 0 ≤ p ≤ 7, and the graph is given at the end of the answer.

Four different positive integers are to be chosen so that they have a mean of 2017.
What is the smallest possible range of the chosen integers?
The smallest possible range of the chosen integers is; 2015
What is the smallest possible Integer?First of all, the range of a set of numbers is the difference between the largest and smallest numbers in the set.
The smallest range of a set of four different positive integers is 3. This occurs when the integers are consecutive, and only in this case. We first show that we cannot have four consecutive integers
with a mean of 2017.
Assume, to the contrary, that n is a positive integer such that the consecutive integers n, n + 1, n + 2 and n + 3 have 2017 as their mean.
Thus;
[n + n + 1 + n + 2 + n + 3]/4 = 2017
4n + 6 = 2017 * 4
n = 2015.5
Since n is an integer, then this can't be true. However, with a little tweaking of this, we can tell that we can use 2015 as our least integer.

there is no prior information about the proportion of americans who support free trade in 2018. if we want to estimate a 97.5% confidence interval for the true proportion of americans who support free trade in 2018 with a 0.16 margin of error, how many randomly selected americans must be surveyed? answer: (round up your answer to nearest whole number)
The number of randomly selected Americans that must be surveyed is equal to 38 if the confidence interval is 97.5% with a 0.16 margin of error.
First, we calculate the critical value as follows;
a = (1 - 0.975) = 0.025 = 0.025 / 2 = 0.0125 = (1 - 0.0125) = 0.9875
Z - Critical value = NORM.S.INV (0.9875) = 1.96
As margin of error(ME) = 0.16
Therefore;
n = pq(Z²) / ME²
n = 0.5 × 0.5 (1.96)² / (0.16)²
n = 0.25 × 3.8416 / 0.0256
n = 0.9604 / 0.0256
n = 37.515
Rounding it to the nearest whole number;
n = 37.515 = 38
Hence 38 randomly selected Americans must be surveyed if the estimated confidence interval is 97.5% and the margin of error is 0.16.

Suppose you started a savings account when you were 5 years old with $100, but you never
added any more money to it. How much money is in your savings account now if you were
getting 3% interest compounded quarterly?
Round your amount in your account to the nearest cent.
Answer: no idea
Step-by-step explanation:
Neil puts 1500 pounds in the bank,at a rate of 3% compound interest.
Jerry puts 1500 pounds in the bank at a rate of r % simple interest.
After 5 years they have the same amount.
Find r
When Jerry puts 1500 pounds in the bank for 5 years then the rate of interest which makes the amount equal for Jerry and Neil is 1.85%.
Given Neil puts 1550 pounds in the bank, at a rate of 3% compound interest.
we need to calculate the total amount and interest at the end of 5 years.
P=1500 pounds
r = 3%
n = 5 years.
A = P(1+r/100)ⁿ
A = 1500(1+3/100)⁵
A = 1500(103/100)⁵
A = 1500 × 103/100 × 103/100 × 103/100
A = 3278181/2000
A = 1639.09
C.I = A-P
= 1639.09 - 1500
= 139.09
From the question, After 5 years they have the same amount.
Therefore we use the amount to calculate rate of interest as :
A = 1639.09
Simple interest = 1639.09 - 1500
= 139.09
Therefore, P = 1500
I = 139.09
t = 5 yrs
R = (100×I)/(P×t)
R = (100×139.09)/(1500×5)
R = 1.85%
Hence the rate of interest is 1.85%.
