Answer:
The y-intercept is (0, 4/3) and the equation of is y = -1/6x + 4/3. if the y-coordinate of point c is 13, its x-coordinate is -70
Equation of a lineThe equation of a line in slope-intercept form is y = mx + b
where;
m is the slope
b is the y-intercept
Given the coordinate points (14, -1) and (2, 1)
Slope = 1-(-1)/2-14
Slope = 2/-12
Slope = -1/6
Determine the y-intercept
1 = -1/6(2) + b
1 = -1/3 + b
b = 1 + 1/3
b = 4/3
The given equation of the line is y = -1/6x + 4/3
For the y-intercept
y = -1/6(0) + 4/3
y = 4/3
Hence the y-intercept is (0, 4/3)
For the x-intercept
0 = -1/6(x) + 4/3
1/6x = 4/3
24x = 3
x = 1/8
Hence the x-intercept is (1/8, 0)
If the y-coordinate of point C is 13, hence;
y = -1/6x + 4/3
13 = -1/6x + 4/3
-1/6x = 13 - 4/3
-1/6x = 35/3
-1/2 x = 35
x = -70
The y-intercept is (0, 4/3) and the equation of is y = -1/6x + 4/3. if the y-coordinate of point c is 13, its x-coordinate is -70

Student t distribution
A measurement of a data set's deviation from the mean is referred to as "standard deviation". While a high standard deviation indicates that the data are more spread, a low standard deviation suggests that the data are clustered around the mean.
The average of a group of variables is referred to as the mean in mathematics and statistics. There are several methods for calculating the mean, including simple arithmetic means (adding the numbers together and dividing the result by the number of observations), geometric means, and harmonic means.
We have,
Claim : μ = 83
Sample data : s = 15.1, n = 24, and x = 103
The hypothesis test uses the student t distribution because we are evaluating the mean in this situation, the sample standard deviation of a normal distribution is estimated or supplied, and the population's standard deviation is unknown.

The equation c+d=58 represents the sum of the two numbers.
The equation c+d=58 represents the sentence "The first number is 8 less than half the seco
The equation C=d-8 represents the relationship between the two numbers.
The equation C=d-8 represents the sum of the two numbers.
The number d is 14.
The number c is 44.
The number is 14
Answer:
The following are the correct choices
First : The equation c + d represents the sum of the two numbers
Third: The equation c = (1/2)d - 8 represents the relationship
and the last choice : The number c is 14
Step-by-step explanation:
Translate the word problem into equations and solve for c and d where c is the first number and d the second
Sum is 58 translates to
c + d = 58 (1) ===> First choice
First number is 8 less than half the second number translates to
c = (1/2)d - 8 (2) ==> Third choice
Multiply equation (2) by 2 on both sides giving
2c = d - 16 ==> 2c - d = -16 (3)
Add equations (1) and (3) giving
c + d + 2c - d = 58-16
3c = 42
c = 42/3 = 14 ===> Last choice
Substituting for c in equation (1) gives
14 + d = 58
d = 44

If X = 6 units, Y = 8 units, and h = 6 units, what is the area of the trapezoid?????????
-7th
The area of the trapezoid is 42 square units
How to determine the areaThe formula for area of a trapezoid is expressed as;
Area = a + b/ 2 h
Where;
a is the length of the side = 6 unitsb is the length of its base = 8 unitsh is the height of the trapezoid = 6 unitsNow, to determine the area of the trapezoid, we need to substitute the values of the length of the side and its base with the height of the trapezoid.
Substitute the value into the equation
From the above information, we have that;
Area = 6 + 8/ 2 (6)
Find the quotient
Area = 14/ 2(6)
Area = 7(6)
Multiply through
Area = 42 square units
We have that the area of the trapezoid takes the value 42 square units
Thus, the area of the trapezoid is 42 square units

PLEASE HELP Four different linear functions are represented below. Answer the following questions.
The closest y-intercept is in function 1 so in option (A), the Greatest y-intercept is +4 in function 3 so in option (C), Functions 1 and 2 will have a slope less than 3 option (A) and (B).
What is a graph?The graph is a geometrical representation of a function and can be plotted by taking x's and y's corresponding values within the interval.
For example plot of y = x³ ,y = sinx.
Given four functions,
The y-intercept is a point on the y-axis where the graph intersects therefore coordinate of x will be 0.
In function 1 ⇒ y-intercept = -1 in rest, all it is far from 1 therefore it is close to 0.
The y-intercept of function 3 is →
y = x + 4 ⇒ y = 0 + 4 = 4 which is greatest positive value among all.
The slope of any function associated with two points (x₁, y₁) and (x₂, y₂) is given by
Slope = (y₂ - y₁)/(x₂ - x₁)
The slope of function 1 has points (0,-1) and (1,-5)
(-5 + 1)/(1 - 0) = -4 < 3
The slope of function 2 →
(5 - 8)/(-1 + 2) = -3 < 3 rest all function have slope as > 3.
Hence "The closest y-intercept is in function 1, the Greatest y-intercept is +4 in function 3 , Functions 1 and 2 will have a slope less than 3".

The [tex]\lim_{x \to 1} 7x-3=7(1)-3=4[/tex] using the ε − δ definition of a limit.
The value that a function approaches when the input approaches a certain value is known as a limit. Calculus and mathematical analysis are not possible without limits, which are also required to determine continuity, derivatives, and integrals.
The limit of f(x) at x = c is L according to the epsilon-delta definition of limits if ε > 0 there's a δ > 0 such that if the distance of x from c is less than, then the distance of f(x) from L is less than ε. The idea that we can approach L as closely as we like is expressed in this way.
[tex]\lim_{x \to a}f(x)= L[/tex] if ∀ ε > 0, ∃ δ > 0
0 < | x − a| < δ
⇒ | f(x) − L | < ε
Now, consider the limit
[tex]\lim_{x \to 1} 7x-3=4[/tex]
Here, f(x) = 7x - 3, a = 1, L = 4
Proof:
∀ ε > 0, ∃ δ = ε > 0

The final value of the equation is x=e²/3
A natural log is a logarithm with the base "e." It is represented by the symbol "ln." In other words, loge = ln. In other words, the natural logarithm lacks a base. When "ln" is recognized automatically, "e" is assumed to be its base. The same set of logarithmic rules applies to all logarithms, including the natural logarithm. As a result, the following are the key natural log rules (also known as ln rules):
ln (mn) = ln m + ln nln (m/n) = ln m - ln nln mn = n ln mln a = (log a) / (log e)ln e = 1ln 1 = 0log∨b m = x ⇒ m = b∧xlog∨e(3x)=23x=e²x=e²/3Therefore the final answer for the given question is x=e²/3

The bis the set of possible input values, and the range is the set of all possible output values of the graph.
In the sets:
Union (∪) of two sets means all the elements in the two sets without repeating the same elements
Intersection (∩) of two sets means the common elements in the two sets
∵ Set L = {0 , 20 , 40 , 80 , 100}
∵ Set M = {5 , 10 , 15 , 20 , 25}
∵ Set N = {10 , 20 , 30 , 40 , 50}

M ∩ N = {10 , 20}
Now find the union of L and {10 , 20}
L ∪ {10 , 20} means all elements in L and {10 , 20} without repeating the same elements
L ∪ {10 , 20} = {0 , 10 , 20 , 40 , 80 , 100}

The coordinates of point T are (0,5). The midpoint of ST is (6,-2) find the coordinates of point S
The coordinates of point S are (12,₋9)
Given, coordinates of T are (0,5)
midpoint of ST is (6,₋2)
When it is necessary to determine the precise center point between two specified points, the midpoint formula is used. So you may use this method to determine the point that divides a line segment specified by two points in half.
coordinates of S are = ?
we know the midpoint formula is (x₊x₁)/2 , (y₊y₁)/2
The midpoint calculation is the same as averaging two numbers. As a result, by adding any two integers together and dividing by two, you may find the midpoint between them.
substitute the given values in the formula.
(6,₋2) = (x₊0)/2 , (y₊5)/2
for the x value of S:
x/2 = 6
x = 12
for the y value of S:
y₊5/2 = ₋2
y ₊ 5 = ₋4
y = ₋4 ₋ 5
y = ₋9

6000 people didn't cast their vote and 1500 votes are not valid in the election
Given that In a municipal election, two candidates, P, and Q, ran for the position of Mayor, and 35000 people voted. Voters were supposed to vote for only one candidate. P received 22000 votes, Q received 5500 votes, and 1500 cast votes for P and Q.
Number of votes for P =22,000
Number of votes for Q= 5500
1500 cast votes to Both P and Q, these votes are not valid because each one is supposed to vote only for one.
Therefore, the number of votes not valid is 1500
Total people cast vote= sum of votes for every party
Total people cast vote=22,000+ 5500+1500
