Hey you guys I have a midterm coming soon and I was just wondering how you guys would go about solving these types of problems.
For example for the first part ,dot product is basically the x and y multipled with each other and then you add.
Here is the problem I am working on in Business Statistics II: For a sample of size 20 taken from a normally distributed population with a known standard deviation equal to 7.2, a 90% confidence interval for the population mean would require the use of: a. z=1.96 b. t=1.328 c..

Hi all. Says to solve and round to four decimal places.
e^x+1=10^x
I got as far as puting
ln (e^x+1)=ln(10^x)
(x+1)ln(e) = x ln (10)
Not sure how to solve after than. Book says the.
Hi, i haven't used trig in a long time and i'm having trouble. The question is the circumference of a fountain is 90 feet. The angle to the top is 45 degrees. How tall is the fountain? Could someone give a step by step solution, and explain how you got.
How do I get from the eqations to the values of x2 x3 x4
Substitute all the values, And Equation (ii) and (iii) are identical then x2=x3=r and take x1=s and x4=k. The vector of the form is a solution for any number s, r and k..
Hi, I have been fine with all the simultaneous equations I have done so far, howerever these questions I keep getting the wrongs answers to:
a) 4x= y +7
3x^2 - 4y = 7
b) 3x + 2y = 4
.
Here it is:
According to Proposition 4.10, if A is an m times n matrix, then for each b epsilon C(A), there is a unique x epsilon R(A) with Ax = b. In each case, give a formula for that x..
How do I solve the equation for y? That is y = +/-
9x2 - 25y2 = 225
Choices: 1. y = +/- 5/3 * Sq Rt ( x2 -9); 2) y = +/- 3/5 * SqRt ( x2 - 25); 3) y= +/-.
How can I determine the function given those input and output values ?
Input: 3,7 -> output: 6
Input: 5,3 -> output: 2
Input: 6,14 -> output: 6
Thanks.
Hi I need help doing the first 5 coefficents of this power series, I guessed and got those 2 right but I got the power series
(-1)^n(16x^2)^n*2 and then plugged in 0 for the n's and so on to solve and am getting it wrong! Please help!!:/.
Hi , im writing my first university maths exam this saturday and below is one of the questions which is really confusing me By using the addition formulae show that cos(A + B) + cos(A ¡ B) = 2 cosAcosB: Setting u = A + B and v = A.
Hi everyone, i'm doing my homework and the question gave me 2 point to let me find the parametric equation
(4,1/2,1/3), (-6,-1/4,1/6) i got x=4-10t, y=1/2-3/4t, z=1/3- 1/6t but the answer shows x=4+10t, y=1/2+3/4t, z=1/3+ 1/6t which the sign are all opposite, i didn't understand what the.

Suppose that there are two risky assests A1 and A2, with U1=2 and U2=5
a) what portfolio of A1 and A2 achieves 3% expected return ?
b) what portfolio of A and B achieves a sqrt of 5.
Fourth-degree Taylor expansion at a = pi/2 Find the Taylor series expansion for each function for the given value of a. One important use of power series expansions is to compute the numerical values of trans. Sketch several periods of each given function and find its Fourier series expansion.

How do I find the domain, range and vertical asymptotes for -3cot(4x-2)+4? I would very much appreciate it if you can use as much detail as possible. Thank you! :).
Consider the the curve with position vector r(t) = at^2(i-vector)+bt(j-vector)+c*ln(t)(k-vector), 1<=t<=T.
1) Express the length of the curve as a definite integral.
2) Evaluate the integral if b^2=4ac.
Here it is: (9^62773 + 2)^83721
Yes thats (9 to the 62773 power plus 2) to the 83721 power.
Now heres the rest of the problem...after finding the Huge number i have to find its digital sum. if u dont know what that means.
here is the Question
A linear function f : R rightarrow R has the form f(x) = ax + b, where a and b are real numbers. Show that the composition of two linear functions is linear. (Hint: you can take for granted the fact that the.
