Answer:
30.7%, 0.3, or 4/13
Step-by-step explanation:
The correct procedure for this problem is:
The number of men that passed the test and the number of men should be located as the numerator and denominator of the fractional number.12/39 is our fraction, which we can reduce to 4/13We can change it to a percent and a decimal, which would be 30.7% and 0.3.How do you solve for n and what is the rule?
Answer:
Looking at the first two given ordered pairs (3, 5) and (4, 7), it appears that for every increase of 1 unit of x, there is an increase of 2 units of y.
Let's check by writing the next ordered pairs using this rule:
(5, 9) (6, 11) (7, 13) (8, 15)
As the the ordered pair (8, 15) is in the table, then we can confirm that this is the rule.
Writing the rule as an equation:
y = 2x - 1
Therefore, n = 6
Answer:
y = 2x - 1
n = 6
Step-by-step explanation:
Hello!
This is an arithmetic sequence.
An Arithmetic sequence, also known as an arithmetic progression, is a string of numbers that follow a pattern where the difference between two terms is always the same (constant).
An Arithmetic sequence is modeled by the explicit function:[tex]\bold{t(n) = (CD)n + t(0)}[/tex]
t(n) = output (y - value)CD = common difference (slope)n = input ( x-value)t(0) = starting value (y-intercept)Let's go step by step to solve these equations:
Step 1: Common Difference
The common difference of a sequence is similar to the slope of a line. The slope formula is given as [tex]\bold{\frac{y_2 - y_1}{x_2-x_1}}[/tex].
We can input values of x and y to find the common difference
[tex]\frac{y_2 - y_1}{x_2-x_1}[/tex][tex]\frac{7 - 5}{4 - 3}[/tex][tex]\frac21 = 2[/tex]We have the CD, 2!
Step 2: Starting Value
The starting value can be shown as the y-intercept of the line or the origin point of the sequence.
To find the starting value or t(0), we can input an x and y value for "n" and "t(n)"
t(n) = (CD)n + t(0)5 = 2(3) + t(0)5 = 6 + t(0)-1 = t(0)We know have the starting value, -1!
Step 3: The Equation
We now have all the values for our equation. let's bring our attention back to the input and output variables. Since we know that "t(n)" is the same as "y" and "n" is the same as "x", we can plug that instead of t(n) and n.
t(n) = (CD)n + t(0)t(n) = 2n -1y = 2x - 1Solve for n:
With our equation, we can plug in 11 as the output and solve for n.
y = 2x - 111 = 2x - 112 = 2x6 = xn = 6

Another way to solve this is to find the Recursive Equation
The Recursive Equation is only meant to find the next term, it doesn't do so well in finding the terms in the long run.
The basic form of a recursive equation is t(n + 1) = t(n) + (CD); where t(0) is ____
I'm not going to go in-depth with this, but you can see the values that we solved above can be implemented here.
Our recursive equation is t(n + 1) = t(n) + 2; where t(0) is -1
The port outside of the semi-colon represents where the sequence starts. If only t(n+1) = t(n) + 2 is given, we could start at 5, and go as 5, 7, 9...etc.
We would start by finding t(1) by doing:
t(0 + 1) = t(0) + 2; where t(0) = -1t(1) = -1 + 2t(1) = 1We can confirm this using our explicit rule: y = 2x - 1
y = 2(1) - 1y = 2 - 1y = 1a
The diameter of a semicircle is 6 yards. What
is the semicircle's perimeter?
d=6 yd
Use 3.14 for a.
Given -
the diameter of a semicircle is 6 yards.ie. d = 6yd
ps - use 3.14 for a
To find -
the semicircle's perimeterSolution -
As we know the formula to find the perimeter of the semicircle is 2r + πr.
But A.T.Q we are only provided with the diameter. As we know that the radius is half of the diameter. ie, r = d/2.
Hence, d = 6
r = 6/2
r = 3 yd
Perimeter of semicircle = 2r + πr
Perimeter of semicircle = 2(3) + 3.14(3)
Perimeter of semicircle = 15.42 yd
Hence forth the semicircle's perimeter is 15.42 yd

In what year did the nfl vote to create a $430 million pool of money, funded by the top 15 clubs by revenue to be distributed to the bottom 15 clubs?.
The year in which the NFL voted to create a $430 million fund to help the bottom 15 clubs was 2007.
When did the NFL vote to implement this fund?The NFL voted by a margin of 30-2 in 2007 to create a pool of funds over 3 years that would amount to $430 million.
This money would then be used to help the bottom 15 clubs who might be struggling financially. The hope was that this would make things more competitive in the NFL.

Using the dot plot, the inference is that the number of flocks observed on the second day was less than in the first.
What does a dot plot show?The dot plot shows the number of times each measure appears in the data-set.
Hence, the mean of the data-set corresponding to day 1 is given by:
M1 = (4 x 4 + 7 x 5 + 7 x 6 + 7 x 7)/25 = 5.68
And the mean of the data-set corresponding to day 2 is given by:
M2 = (2 x 8 + 3 x 7 + 4 x 6 + 5 x 4)/25 = 3.24.
M1 > M2, hence, the inference is that the number of flocks observed on the second day was less than in the first.

Answer:
[tex]y = (-3/2)\, x + (-2)[/tex].
Step-by-step explanation:
If [tex](x_{0},\, y_{0})[/tex] is on the equation of the line [tex]y = m\, x + b[/tex], then substituting [tex]x = x_{0}[/tex] and [tex]y = y_{0}[/tex] into the equation would still give an equality: [tex]y_{0} = m\, x_{0} + b[/tex].
In this question, since [tex](-2,\, 1)[/tex] is a point on the line [tex]y = m\, x + b[/tex], equality shall still hold after substituting in [tex]x = (-2)[/tex] and [tex]y = 1[/tex]:
[tex]1 = m\times (-2) + b[/tex].
Similarly, since [tex](2,\, -5)[/tex] is a point on this line, equality shall still hold after substituting in [tex]x = 2[/tex] and [tex]y = (-5)[/tex]:
[tex](-5) = m\times 2 + b[/tex].
The unknowns of both equations are [tex]m[/tex] and [tex]b[/tex].
Solve this system of two equations and two unknowns:
[tex]\left\lbrace\begin{aligned}& (-2)\, m + b = 1\\ & 2\, m + b = (-5)\end{aligned}\right.[/tex].
[tex]\left\lbrace\begin{aligned}& m = -\frac{3}{2} \\ & b = -2\end{aligned}\right.[/tex].
Therefore, the equation of this line would be:

An exterior angle of a triangle is equal to the sum of the remote interior angles.
(3x +6)° = 31° +35°
3x +6 = 66 . . . . . . . . . . divide by °, collect terms
3x = 60 . . . . . . . . subtract 6
x = 20 . . . . . . . divide by 3
The value of y is the supplement of (3x+6)°, and of the sum (31 +35)°.
y = 180° -66° = 114°
The values of x and y are 20 and 114°, respectively.

An aluminum bar 3 feet long weighs 12 pounds. What is the weight of a similar bar that is 3 feet 4 inches long?
Answer: 13 [tex]\frac{1}{3}[/tex] pounds
Step-by-step explanation:
We will set up a proportion. I will have the weight, in pounds, on the top (numerator) and the length, in inches, on the bottom (denominator).
[tex]\frac{12}{36} =\frac{x}{40}[/tex]
Cross-multiply:
36 * x = 12 * 40
36x = 480
Divide both sides of the equation by 36:
x = 13 [tex]\frac{1}{3}[/tex] pounds
Answer:
Step-by-step explanation:
First find unit weight.
1 foot = 12 inches
3 ft = 3*12 = 36 inches
3ft 4 inches = 36 + 4 = 40inches
Weight of 36 inches long bar = 12 pounds
Weight of 1 inch bar = 12/36
[tex]\text{Weight of 40 inches long bar = $\dfrac{12}{36}*40$}[/tex]
= 13.3 pounds
