The new balance in Mr. smith account will be $263.42.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have Mr. Smith has an account balance of -$275.78. He deposits $539.20 into his account.
Assume that the new amount in his account will be [x]. Then -
[x] = 539.20 - 275.78
[x] = 263.42
Therefore, the new balance in Mr. smith account will be $263.42.

Find 33,688 divided by 8.
Suppose each stock in Andre’s portfolio has a correlation coefficient of 0.40 (rho = 0.40) with each of the other stocks. The market’s average standard deviation is approximately 20%, and the weighted average of the risk of the individual securities in the partially diversified four-stock portfolio is 39%. If 40 additional, randomly selected stocks with a correlation coefficient of 0.30 with the other stocks in the portfolio were added to the portfolio, what effect would this have on the portfolio’s standard deviation?
Answer:
Explained below.
Step-by-step explanation:
The correlation coefficient for the portfolio with each of the other stocks is 0.40.
This correlation coefficient is less than 1. This implies that the portfolio’s assets are weakly correlated with each other.
The portfolio profits from modification. Randomly selected stocks are added to the portfolio.
The correlation coefficient of these stocks with the other stocks in the portfolio is about 0.30.
Therefore adding these randomly selected stocks will decrease the portfolio’s standard deviation.
Company-specific risk in portfolio can be reduced by this diversification but systematic or market risk can’t be eliminated. Thus the risk will (σ) decrease slowly until σp reaches to the average standard deviation of returns on the market i.e. about 20 %.

Write the word sentence as an equation. Then solve.
10 more than a number c is 3.
Answer:
10 +c=3
C=3-10
C=-7
.....
Answer:
c = -7
first, make the equation.
10 more than a number c is 3
the variable is c, according to the sentence.
c
"10 more than a number c"
c + 10
"10 more than a number c is 3 "
c + 10 = 3
now that you have your equation, time to solve it.
it's important to know that if you do something to an equation, as long as you do it to both sides the equation is still true.
for example.
2 + 2 = 4
if you add 1 to both sides of the equation,
2 + 2 + 1 = 4 + 1
5 = 5
this is still true.
Solving the equation.c + 10 = 3
subtract 10 from both sides of the equation.
c + 10 - 10 = 3 - 10
c = 3 - 10
c = -7
Sam decides to download some new music. She downloaded 3 albums and 10
singles, and her total was $61. The next day she purchased more music from the
same retailer and downloaded 6 more albums and 8 singles for a total of $74.
Assuming that all albums and singles are the same price, how much did she spend on
each album and each single? Write a system of equations to represent this
situation. Then solve for the solution using the elimination method.
Answer:
An album costs $7 while a single cost $4
Step-by-step explanation:
Let the amount spent on singles be $x while the amount spent on albums be $y
First day, she downloaded 3 albums and 10 singles that cost $61
Hence;
3y + 10x = 61 ••••••••(ii)
Second day, she downloaded 6 albums and 8 singles for $74
8x + 6y = 74 ••••••••(ii)
We now want to use elimination method to solve both equations
Multiply equation i by 2 and ii by i
20x + 6y = 122
8x + 6y = 74
Subtract ii from i now
12x = 48
x = 48/12
x = 4
Recall;
3y + 10x = 61
substitute for x
3y + 10(4) = 61
3y + 40 = 61
3y = 61-40
3y = 21
y = 21/3
y = 7
An album costs $7 while a single cost $4

Answer:
5)y=2x 6)y=12x 7)y=3x-2 8)y=1/4x+2
Step-by-step explanation:
Look at the y-intercept first if crosses the origin then don't need to write anything. If it does you add it after the slope.
To find slope you can count how many units up or down it does and how many left or right.
Then write i as rise/run.
