Answer:
N = [tex]\frac{3}{4}[/tex] * v
Step-by-step explanation:
Since the value that we are provided is a fraction that is tied to the number of books that Victor has, we would simply need to multiply this fraction by the total number of books that Victor has. This value is represented by the variable v while the total number of books that Nora has is represented by the variable N. Therefore, the expression would be the following
N = [tex]\frac{3}{4}[/tex] * v

What is the first step to solve the following system of equations using substitution?
X-y=-1
2x-y=3
A.) Solve the first equation for x.
B.) Divide the second equation by 2.
C.) Multiply the first equation by 2.
D.) Add the two equations together.
Answer:
Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x
Thus, option A) is true.
The solution to the system of equations be:
[tex]x = 4, y = 5[/tex]
Step-by-step explanation:
It is important to remember that when we solve the system of equations, the first step we need to do is to solve one of the equations for one of the variables.
Given the system of equations
[tex]x - y = -1[/tex]
[tex]2x - y = 3[/tex]
Step 1: Solve one of the equations for one of the variables. Let's solve the first equation for x
[tex]x-y=-1[/tex]
Add y to both sides
[tex]x-y+y=-1+y[/tex]
[tex]x=-1+y[/tex]
Thus, option A) is true.
NOW LET US SOLVE THE REMAINING PORTION
[tex]\mathrm{Subsititute\:}x=-1+y[/tex] to solve for y
[tex]\begin{bmatrix}2\left(-1+y\right)-y=3\end{bmatrix}[/tex]
[tex]-2+y=3[/tex]
[tex]y=5[/tex]
For x = -1 + y
substitute y = 5
[tex]x=-1+5[/tex]
[tex]x=4[/tex]
Thus, the solution to the system of equations be:
[tex]x = 4, y = 5[/tex]

Meg ate 3/8 pound of blueberries. Jon ate 7/8 pound of blueberries. How many more pounds did Jon eat than
Meg?
Please help me
Answer:
4/8 more pounds
Step-by-step explanation:
7/8-3/8=4/8
Answer:
Jon ate 5/8 more pounds of blueberries than Meg.
Step-by-step explanation:
This is because the question is asking for the difference between how many blueberries Meg ate, and how many Jon ate. Therefore, we have to use subtraction.
7/8 - 3/8 = 5/8, therefore Jon ate 5/8 lb more than Meg.

Step-by-step explanation:
The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 customers to check out was 3.0 minutes. It is known that the standard deviation of the checkout time is 1 minute. Refer to Exhibit 8-2. If the confidence coefficient is reduced to .80, the standard error of the mean _____.
Answer:
The standard error of the mean remains unchanged.
Step-by-step explanation:
Given that:
The standard error (S.E) of the mean [tex]= \dfrac{\sigma}{\sqrt{n}}[/tex] with is independent of confidence coefficient.
The margin of error [tex]E = z \times S.E[/tex]
This explains the claim that as the confidence coefficient reduces, the z-value also reduces, so as the Margin of error (E) but the standard error will always remain unchanged.
i.e.
From the question;
sample size n = 100
standard deviation = 1
mean = 3.0
The standard error (S.E) of the mean [tex]= \dfrac{1}{\sqrt{100}}[/tex]
= 0.1
So, if the confidence coefficient is reduced to 0.80, the standard error of the mean remains unchanged.

Properties of Exponential Function for Roots.
[tex]a^{\frac{m}{n}}=\sqrt[n]{a^m}[/tex]
The first one is wrong as 4^1/2 would equal √4 = 2
The second choice is correct.
The third choice is correct because ∛8 = 2 and √4 also = 2
The fourth choice is wrong because √8 = 2√2
The fifth choice is also wrong because 2^1/2 would be √2 while √32 is 2^5
The sixth choice is 3^3/2 which would equal √27 = 3√3 which is correct.

Location of Air Transport
In this, air traffic are mainly managed by coordinates study, to find the location of a particular location for any change in location of a plane it is used.
Map Projections
The points usually provides the frame of references for your data, to locate the position on the surface of earth.
GPS
We use GPS for any specific location identifier on the earth which we get in the form of coordinates, these are points showing the asked location.
Latitude and Longitude
These are the parameter used to locate any specific point on the earth, Latitude and Longitude are always defined by a point, they constitute a coordinates system to identify any geographical location.
