Answer:
[tex]\sf \dfrac{2}{3}[/tex]
Step-by-step explanation:
To simplify a fraction, divide the numerator and denominator by their greatest common factor (GCF).
List all the factors of 16 and 24:
Factors of 16: 1, 2, 4, 8, 16Factors of 24: 1, 2, 3, 4, 6, 8, 12, 24Therefore, the greatest common factor is 8.
So to reduce 16/24 to its lowest terms, divide the numerator and denominator by 8:
[tex]\implies \sf \dfrac{16}{24}=\dfrac{16 \div 8}{24 \div 8}=\dfrac{2}{3}[/tex]

Given the table below, write a linear equation that defines the
dependent variable, a, in terms of the independent variable, p.
Someone help
Answer:
a = 4p + 3
Step-by-step explanation:
The general form of a linear equation is y = mx + b
where y is the dependent variable, x the independent variable
m = slope(rate of change)
b = y-intercept which is the value of y when x = 0
In this problem, instead of x we are asked to use p and instead of y we are using a
Therefore we get
a = mp + b
We have to compute m and b
Since b is the value of a when p = 0, we can easily see that a = 3 when p = 0
Therefore:
a = mp + 3
To determine m, take any value of p, find the corresponding a from the table, plug in these values and solve for m
When p = 1, a= 7
So we get
7 = m(1) + 3
7 = m + 3
or
m = 7-3 = 4
So the equation is
a = 4p + 3
You can verify this as correct by plugging in different values for p from the table and checking if you get the corresponding a value

What is meant by an equation?An equation in French is defined as having one or more variables, whereas an equation in English is any well-formed formula consisting of two expressions combined with an equals sign.
Solving a variable equation includes determining which variables' values result in equality. Unknowns are the variables for which the equation must be solved, while equation solutions are the unknown values that satisfy the equality. An equation is a mathematical phrase with two equal sides separated by an equal sign. An equation is 4 + 6 = 10. We can see 4 + 6 on the left side of the equal sign and 10 on the right.
Given equations are:
2x + 3y = 49

Step-by-step explanation:
add the number of days that the chicken laid 5 or more eggs
5 + 5 + 2 = 12
From the given frequency table, we observe that the chicken lays 5 or more eggs on day 4, 5 and 6, and the eggs laid by the chicken are the greatest on day 4.
What is a frequency table?A frequency distribution table is a tool for structuring the provided data in a way that makes sense and facilitates comprehension. Two or three columns make up a frequency distribution table.
here, we have,
All of the results are shown in the first column as individual values or as class intervals.
The table's second column contains the results' totals, which also display the frequency as vertical lines. It's not required.
The frequency of each result is revealed in the third column.
The frequency table uses lines to depict the number of laid eggs. Here, 5 is represented using a hashed line over four lines. Thus, we see that the maximum number of eggs laid are 6, on day 4.
Also, the chicken lays 5 or more eggs on day 4, 5 and 6.

The following table shows the number of times key club students at Peconic high school went to echo beach last summer.
Number of echo beach trips: 5,6,8,9,12,14
Frequency: 8,7,11,15,3,4
a. How many students are in the key club?
b. Find the mean, median, mode, range, variance, and standard deviation for the distribution. Round to the nearest tenth
a) The students in the key club are 48students.
b) The mean, median, mode, range, variance, and standard deviation for the distribution are 8.3, 8, 9, 9, 303.52, 17.4
What is meant by standard deviation?The standard deviation is a statistic that measures the amount of variation or dispersion in a set of numbers. A low standard deviation implies that the values are close to the mean of the set, whereas a large standard deviation shows that the values are spread out over a greater range.
Given,
The number of echo beach trips are 5,6,8,9,12,14.
And also given that the frequencies are 8,7,11,15,3,4
a) The students in the key club are,
∑[tex]F_{i}[/tex]=8+7+11+15+3+4
=48
∑[tex]F_{i}[/tex]=48
Therefore, the students in the key club are 48students.
b) Mean= ∑[tex]X_{i}[/tex][tex]F_{i}[/tex]/∑[tex]F_{i}[/tex]

position 8 8+7=15 15+11=26 26+15=41 41+3=44 44+4=48
The value of X at [tex]24^{th}[/tex] position is 8 and [tex]25^{th}[/tex] position is also 8
Then, Median=(8+8)/2
=8
Therefore, Median=8.3
Mode= Highest frequency corresponding to X value

2x/2=22/2. (to remain with x value)
x=11
therefore 2x+ y results to 2(11) +3=25
Answer:
2x + y = 25
Step-by-step explanation:
Given equations:
[tex]\begin{cases} 3x + 5y = 48\\\;\;2x-y=19\end{cases}[/tex]
Rearrange the second equation to isolate y:
[tex]\implies 2x-y=19[/tex]
[tex]\implies 2x-19=y[/tex]
Substitute the found expression for y into the first equation and solve for x:
[tex]\implies 3x+5y=48[/tex]
[tex]\implies 3x+5(2x-19)=48[/tex]
[tex]\implies 3x+10x-95=48[/tex]
[tex]\implies 13x=143[/tex]
[tex]\implies x=11[/tex]
Substitute the found value of x into the equation for y and solve for y:
[tex]\implies y=2x-19[/tex]
[tex]\implies y=2(11)-19[/tex]
[tex]\implies y=22-19[/tex]
[tex]\implies y=3[/tex]
Therefore, the solution of the given system of equations is:
x = 11, y = 3To find the value of 2x + y, substitute the found values of x and y into the expression and solve:
[tex]\begin{aligned}\implies 2x+y&=2(11)+3\\&=22+3\\&=25\end{aligned}[/tex]
Therefore:
2x + y = 25Find g(x), where g(x) is the translation 5 units down of f(x)=x2.
Write your answer in the form a(x–h)2+k, where a, h, and k are integers.
If we want to translate (aka move) [tex]f(x) = x^2[/tex] down 5 units, we need to subtract 5 from the [tex]x^2[/tex].
[tex]g(x) = x^2-5[/tex]
The [tex]k[/tex] in the [tex]a(x-h)^2 +k[/tex] form will always be the vertical translation component. If you translate up, [tex]k[/tex] is positive. If you translate down, [tex]k[/tex] is negative.

The best fit line is given by the equation y = 0.404x - 5.18, where y
represents the height of the plant above ground level, and x represents the
number of days since it was planted.
a. What is the y-intercept of the best fit line? What does the y-intercept of the line mean in this situation? Is it reasonable?
The y-intercept of the line of best fit is -5.18cm and it is showing the initial height of the plant immediately it was planted and it is not reasonable because it shows a negative height
The general form of the equation of a line in slope intercept form is expressed as;
y = mx + c
where;
m is slope
c is y-intercept.
Now, we are given the equation of the line of best fit as;
y = 0.404x - 5.18
where;
y represents the height of the plant above ground level.
x represents the number of days since it was planted.
a) From the given equation, we see that the slope is; m = 0.404 and that the y intercept is -5.18.
Now, what the y-intercept means is that the height of the plant is 5.18 cm below the ground and this is not reasonable.
