Answer:
B. 38%
Explanation:
Given parameters:
Number of hits = 5hit
Total hits = 13
Unknown:
Percentage of hits shed made = ?
Solution;
The percentage of hit made = [tex]\frac{number of hits }{Total hits}[/tex] x 100
input the parameters and solve;
Percentage of hit made = [tex]\frac{5}{13} x 100[/tex]
Percentage of hit = 38%
Percentage of hit = 38%
In the diagram below, find the value of y....
Answer:
y = 130
Step-by-step explanation:
(4x+8) + (3x-19) + (x+7) = 180
4x + 8 + 3x - 19 + x + 7 = 180
(4x + 3x + x) + (8 -19 + 7) = 180
8x - 4 = 180
8x -4 +4 = 180 +4
8x = 184
8x/8 = 184/8
x = 23
3(23) - 19 = 50
50 + y = 180
180 - 50 = y
y = 130

What is the distance of the line?
Remember the distance formula is (23 - 23) + (42 -
Answer:
The distance of the line is 10.82
Step-by-step explanation:
Distance Between two Points in the Plane
Given two points A(x1,y1) and B(x2,y2), the distance between them is:
[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
The graph clearly shows the points (-5,4) (4,-2), thus the distance is:
[tex]d=\sqrt{(4-(-5))^2+(-2-4)^2}=\sqrt{9^2+(-6)^2}[/tex]
[tex]d=\sqrt{81+36}=\sqrt{117}=10.82[/tex]
The distance of the line is 10.82

What is the significance of a correlation coefficient of -0.97?
A. The points all lie very close to the line of fit, and the
line is decreasing.
B. The points all lie very close to the line of fit, and the
line is increasing.
C. The points do not follow the line of fit and, the line is
decreasing.
D. The points do not follow the line of fit, and the line is
increasing.
Answer:
It's A. The points all lie very close to the line of fit, and the line is decreasing.
Step-by-step explanation:
The points all lie very close to the line of fit, and the line is decreasing option (A) is correct.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
It is given that:
The value of the correlation coefficient r = -0.97
As we know,
If the value of the correlation coefficient is positive it represents the line of best-fit increasing.
If the value of the correlation coefficient is negative it represents the line of best fit decreasing.
If the value of r is close to 1 then we can say that the correlation between the two variables is very strong.
Thus, the points all lie very close to the line of fit, and the line is decreasing option (A) is correct.

In Mathematics, you must have learned about different types of equations. Here, we are going to discuss the difference between linear and nonlinear equations. The difference between them described here with the help of definitions and examples.
We come across a lot of equations while solving maths problems. Some equations include only numbers and some consist of only variables and some consists of both numbers and variables. Linear and nonlinear equations usually consist of numbers and variables.
Definition of Linear and Non-Linear Equation
Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value.
The major difference between linear and nonlinear equations is given here for the students to understand it in a more natural way. The differences are provided in a tabular form with examples.
What is the difference between Linear and Nonlinear Equations?
To find the difference between the two equations, i.e. linear and nonlinear, one should know the definitions for them. So, let us define and see the difference between them.
Linear Equations
Non-Linear Equations
It forms a straight line or represents the equation for the straight line It does not form a straight line but forms a curve.
It has only one degree. Or we can also define it as an equation having the maximum degree 1. A nonlinear equation has the degree as 2 or more than 2, but not less than 2.
All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form. It forms a curve and if we increase the value of the degree, the curvature of the graph increases.
The general representation of linear equation is;
y = mx +c
Where x and y are the variables, m is the slope of the line and c is a constant value.
The general representation of nonlinear equations is;
ax2 + by2 = c
Where x and y are the variables and a,b and c are the constant values
Examples:
10x = 1
9y + x + 2 = 0
4y = 3x
99x + 12 = 23 and
Examples:
x2+y2 = 1
x2 + 12xy + y2 = 0
x2+x+2 = 25
Note:
The linear equation has only one variable usually and if any equation has two variables in it, then the equation is defined as a Linear equation in two variables. For example, 5x + 2 = 1 is Linear equation in one variable. But 5x + 2y = 1 is a Linear equation in two variables.
Let us see some examples based on these concepts.
Solved Examples
Example: Solve the linear equation 3x+9 = 2x + 18.
Solution: Given, 3x+9 = 2x + 18
⇒ 3x - 2x = 18 - 9
⇒ x = 9
Example: Solve the nonlinear equation x+2y = 1 and x = y.
Solution: Given, x+2y = 1
x = y
By putting the value of x in the first equation we get,
⇒ y + 2y = 1
⇒ 3y = 1
⇒ y = ⅓
∴ x = y = ⅓
What is the key difference between non-linear and linear equations?
A linear equation is used to represent a straight line in a graph, whereas non-linear equations are used to represent curves.
How does the graph of linear and non-linear equations look?
A linear equation graph is a constant slope whereas the graph of the non-linear equation shows the variation in slope at different points.
How is the linear equation represented? Give an example.
The general representation of linear equation is y = mx+c,
where m = slope of the line
x and y are the variables
c is the intercept (constant value)
Example: 2x+y=1
y=-2x+1
How is the nonlinear equation formed?
A non-linear equation is generally given by ax2+by2 = c
where x and y are variables
a,b and c are constant values.
Solve equation
t + (-8) + 13 = 43
Answer:
T=38
Step-by-step explanation:
t−8+13=43
Step 1: Simplify both sides of the equation.
t−8+13=43
t+−8+13=43
(t)+(−8+13)=43(Combine Like Terms)
t+5=43
t+5=43
Step 2: Subtract 5 from both sides.
t+5−5=43−5
t=38
Answer:
t= 38
Step-by-step explanation:
t+(-8)+13=43
t-8+13=43
t=43-13+8
t=30+8
t=38

If gas costs $2.49 per gallon, how many whole gallons of gas could you buy with $15.00?
(Make sure to answer with a whole number.
Answer: 6.02
Step-by-step explanation:
If we know 1 gallon = 2.49
We would have to do 15.00 divided by 2.49 in order to figure out how many gallons we need. When we do that we would get 6.024 but you can round by the nearest tenth because you need to have a whole number and you would get 6 ·ω·

Answer:
You meant 1 1/2. Answer : Y intercept
Step-by-step explanation:
The slope of the line on the graph as per the given scenario is 2.
What is Graph?In mathematics, a graph is a visual representation of a set of data or mathematical relationships.
Graphs are used to show the relationship between two or more variables and can be represented in a variety of formats, including line graphs, bar graphs, scatter plots, and more.
To find the slope of a line, we need to determine how much the y-value changes for every 1-unit increase in the x-value. Looking at the graph, we can see that the line passes through the points (1, 2) and (2, 4).
To find the slope, we can use the slope formula:
slope = (change in y) / (change in x)
If we let (x1, y1) = (1, 2) and (x2, y2) = (2, 4), then the slope is:
slope = (y2 - y1) / (x2 - x1)
slope = (4 - 2) / (2 - 1)
slope = 2
Therefore, the slope of the line on the graph is 2.

Which math PROPERTY is this? If 12 = 17 - 5, then 17 - 5 = 12
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
Tip: The symmetric property of equality states that no matter what side the equations and answer are it will still be equal, but it only works for the equal sign.
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
What is Number system?A number system is defined as a system of writing to express numbers.
Given that 12 = 17 - 5, then 17 - 5 = 12
we need to check which property will be used.
The math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
The symmetric property of equality is really quite simple. This property states that if a = b, then b = a. That is, we can interchange the sides of an equation, and the equation is still a true statement.
Hence, the math property for 12=17-5 then 17-5=12 would be the symmetric property of equality.
