Statement 1 is correct and Statement 2 is not correct.
As A, B and C represent distinct non-zero digits
For least value of x
Let A=1, B=2, C=3
The possible numbers that can be formed using 1,2,3 are 6 {using permutations}
123, 132, 213, 312, 231, 321
x is the sum of all possible 3-digit numbers formed by A, B and C without repetition so
x= 123+ 132+ 213+ 312+ 231+ 321
x=1332
So statement 1 is correct
statement 2 cannot be correct as least value of x is 4-digit so greatest value of x cannot be a three digit number.
The 4-digit least value of x is 1332 so Statement 1 is correct and Statement cannot be correct.

Write an explicit formula for the sequence 1,4,7,10... Then find a14.
Answer:
The formula is [tex]a_n = 3n-2[/tex]
The 14th term is 40, in other words, [tex]a_{14} = 40[/tex]
========================================================
Explanation:
The given sequence is 1, 4, 7, 10, ...
Subtract each adjacent term:
4-1 = 37-4 = 310-7 = 3This shows that each term is increasing by 3. This is the common difference, so d = 3.
The first term is [tex]a_1 = 1[/tex]
The nth term of the arithmetic sequence is...
[tex]a_n = a_1 + d(n-1)\\\\a_n = 1 + 3(n-1)\\\\a_n = 1 + 3n-3\\\\a_n = 3n-2\\\\[/tex]
As a check, let's plug in say n = 3 to find that:
[tex]a_n = 3n-2\\\\a_3 = 3(3)-2\\\\a_3 = 9-2\\\\a_3 = 7\\\\[/tex]
The third term is 7, which matches with the sequence given to us. I'll let you confirm the other values.
-----------
We'll repeat this idea but now for n = 14 to find the 14th term of the sequence.
[tex]a_n = 3n-2\\\\a_{14} = 3(14)-2\\\\a_{14} = 42-2\\\\a_{14} = 40\\\\[/tex]
The 14th term is 40.
You can make a table of values to help confirm the answer. In the first column you'll have the values of n (1,2,3,...) all the way up to 14. The second column will consist of the sequence 1, 4, 7, 10, ... each time going up by 3 until you reach the 14th term of 40.
A fifth grader takes a standardized achievement test (mean = 125, standard deviation = 15) and
scores a 148. What percent of children made higher than a 148?
the child's percentile rank is 93 th percentile. It means he performed better than [tex]$93 \%$[/tex]of the total number of students.
What is Percentile rank?When compared to other students in the same grade and topic, for instance, a student's percentile rank shows how well they performed. The percentile rank of a student indicates whether their score was on par with or higher than that of the norm group's percentage of pupils. In statistics, the percent of scores in a frequency distribution that are lower than a specific score is known as the percentile rank of that score. A percentile rank returns a numerical value, which really indicates the proportion of people who fall inside that range. Since it is a percentile, its range is always between 1 and 99, with 50 serving as its mean or average rank. Only normalized values or data are ever usable in this fashion.- Mean, $\boldsymbol{\mu}=125$.- Population standard deviation, $\sigma=15$.- Marks obtained by child $(X)=148$Need to find the percentile rank for child's score.
Let[tex]$\mathrm{X}$[/tex]denote marks obtained by the child in the achievement test.
The [tex]$\mathrm{Z}$[/tex]value is given as,
[tex]$$Z=\frac{X-\mu}{\sigma}$$[/tex]
Using equation (1), the required percentile rank for child's score is expressed as,
[tex]& Z=\frac{148-125}{15} \\[/tex]
[tex]& Z=1.533[/tex]
The probability value corresponding to the Z=1.533, obtained from the Z table is 0.93736.
Thus, the percentile is 0.93736.
Therefore, the child's percentile rank is 93 th percentile. It means he performed better than [tex]$93 \%$[/tex]of the total number of students.

343200 fts distance travelled in an hour
5720 ft was travelled in 1 minute and,
95.33 ft distance was travelled in 1 second.
What is miles and foot ?The mile is a customary unit of measurement in the United States and the United Kingdom that is based on the older English unit of length equal to 5,280 English feet, or 1,760 yards. It is often referred to as the international mile or statute mile to distinguish it from other miles.
The British imperial and American customary systems of measurement both use the foot as a unit of length, denoted by the standard symbol: ft. An other sign that is frequently used is the prime symbol, ′. One foot is precisely equal to 0.3048 meters as of the International Yard and Pound Agreement of 1959.
5,280 feet per mile, sometimes known as a statute mile, is a unit of measurement (1.609 km). It derives from the mille passus, or "thousand paces," of the Romans, which was equivalent to 5,000 Roman feet.
65 miles per hour
so 65 * 5280 = 343200 ft travelled in 1 hr
in one minute distance travelled = 343200/60 = 5720 fts
and in one second distance travelled = 5720/60 = 95.33 fts.

He starts with 13.2 gallons of gas in his gas tank. a) Write a slope-intercept equation that models how much gas remains in his tank after each mile of of travel(hint: g/mi)
Given :
Mr. Ford's 2002 Focus would get 36 miles/gallon.
He starts with 13.2 gallons of gas in his gas tank.
To Find :
Write a slope-intercept equation that models how much gas remains in his tank after each mile of of travel(hint: g/mi).
Solution :
Let, required equation is :
y = mx + c
Here, y is gas remains in gallons.
Here, m is slope i.e. miles travelled per gallon.
So, m = -36 ( since gas is decreasing )
Initially distance travelled is 0 i.e. putting x = 0
y = c = 13.2
Therefore, y = -36x + 13.2 this is the required equation.
Is (3,6) a solution to this system of equations?
y=2x+1
y=4x+6
Step-by-step explanation:
y = 2x + 1 -------- (I)
y = 4x + 6 --------(ii)
from eqn (I)
y = 2x + 1
sub y = 2x + 1 in eqn (ii)
2x + 1 = 4x + 6
2x - 4x = 6 - 1
-2x = 5
x = -5/2
sub x = -5/2 in eqn (I)
y = 2(-5/2) + 1
y = -5 + 1
y = -4
Therefore, (x, y) = (-5/2, -4)

Step-by-step explanation:
2x + 48 = 3x - 4 (the measure of an exterior angle of a triangle = the sum of the measures of the two non-adjacent interior angles of the triangle)
=> 4 + 48 = 3x - 2x (on transposing)

A designer is planning a trail mix box that is shaped like a rectangular prism. The front of the box must have the width and height shown. Volume of the box must be 162 cubic inches. What must be the depth, d, of the box?
Answer:
The box must be 2.4 in deep.
Step-by-step explanation:
Front dimensions are 9 in by 7.5 in. Find the area of the front: it is
A = (9 in)(7.5 in) = 67.5 in^2. One way to complete this work would be to divide the given volume by this area, 67.5 in^2.
A slightly different approach follows:
The volume must be 162 in^2. Given V = (width)(height)(depth),
V
(depth) must be -----------------------

What must be added to x³ 3x² 12x 19?
The expression x3 3x2 12x 19 is a polynomial expression in standard form.
To add 24 to this expression, we need to add 24 to each of the terms. This means that the answer is x3 + 3x2 + 12x + 43. To check our work, we can use theFOIL method to expand the expression and make sure that the coefficients of each of the terms are correct. The FOIL method stands for First, Outer, Inner, Last. The first and last terms are the x3 and 43, the outer terms are 3x2 and 12x, and the inner terms are 3x2 and 12x. When we multiply these terms, we get x3 + 3x2 + 12x + 43, which is our final answer.

How do you write an expression in vertex form?
Therefore a quadratic function can be written in vertex form as
y = a(x - h)^2 + k.
Define quadratic function.In mathematics, a polynomial of degree two in one or more variables is referred to as a quadratic polynomial. The polynomial function that a quadratic polynomial defines is known as a quadratic function.
What is a polynomial function?In an equation such as the quadratic equation, cubic equation, etc., a polynomial function is a function that only uses non-negative integer powers or only positive integer exponents of a variable. For instance, the polynomial 2x+5 has an exponent of 1.
A quadratic function can be written in vertex form as y = a(x - h)^2 + k
Where (h, k) is the vertex, and a is the leading coefficient.
y = ax^2 + bx + c (standard form)
y = a(x + b/2a)^2 + c - b^2/4a
y = a(x - h)^2 + k where h = -b/2a and k = c - b^2/4a
For example,when y = 3x^2 - 6x - 5
y = 3x^2 - 6x - 5
y = 3(x^2 - 2x) - 5
y = 3(x^2 - 2x + 1 - 1) - 5 = 3(x - 1)^2 - 8
So, the equation is in vertex form y = 3(x - 1)^2 - 8
Note that this only works for parabolas that opens upwards or downwards, if the parabola opens to the sides, the vertex form is y = a(x-h)^2 +k

Answer:
x= 69°
Step-by-step explanation:
First find the inner angle of the 159°
so you would do 180-159=21
next you add 21 ° to the 90° from the right angle
that gives you 111°
last you do 180-111 and you get 69
Answer:
x = 69
Step-by-step explanation:
180 - 159 = 21
The sum of the three angles of any triangle is equal to 180 degrees, so:
21 + 90 + x = 180
111 + x = 180
180 - 111 = x

How do you find the area of a isosceles triangle without the height?
Since an isosceles triangle has two equal sides, it has two equal angles and two equal heights. Therefore, if you know the length of two sides, you can use the formula A = (1/2)bh to calculate the area, where b is the length of the base and h is the length of the two equal heights.
An isosceles triangle is a triangle with two equal sides and two equal angles. Since the two equal sides also have two equal heights, we can use the formula A = (1/2)bh to calculate the area of the triangle without the height. The formula A = (1/2)bh requires the length of the base (b) and the length of the equal heights (h). Therefore, if you know the length of two sides, you can use the formula to calculate the area of the isosceles triangle without the height.
1. Determine the length of two sides of the triangle.
2. Calculate the area of the triangle using the formula A = (1/2)bh, where b is the length of the base and h is the length of the two equal heights.

The function f is given by f(x)= (x-2) (x+4) . Without using graphing technology, answer the following questions.
1. What are the x-intercepts of the graph representing f?
2. What are the x- and y-coordinates of the vertex of the graph?
3. What is the y-intercept?
Answer:
Step-by-step explanation:
1. What are the x-intercepts of the graph representing f? They are the points on the horizontal axis where the graph touches or crosses the axis. Note that on this axis, y = 0.
2. What are the x- and y-coordinates of the vertex of the graph? Since the function is written as the product of two binomials, we can take these coordinates directly from the binomials: (x - 2) yields x = 2 and (x + 4) yields x = -4.
3. What is the y-intercept? Multiply out these binomials. We get:
f(x) = x^2 + 2 - 8. When x = 0, y = -8. The y-intercept is (0, -8).
1) The x-intercepts of the graph representing f are; 2 and 4
2) The x- and y-coordinates of the vertex of the graph are; (1, -5)
3) The y-intercept is at; (0, -8)
We are given the function; f(x) = (x - 2)(x + 4)
1) The x-intercepts of a graph are the points where the graph crosses the x-axis. The x-intercepts are the value of x when f(x) = 0. Thus, the x-intercepts here are 2 and 4.
2) The vertex is the lowest point of the graph in this case as the parabola opens upwards.
Let us expand the function to get;
f(x) = x² - 2x + 4x - 8
f(x) = x² + 2x - 8
where; a = 1, b = 2, c = -8
Formula for the x-coordinate of the vertex is;
x = -b/2a
x = -2/2(1)
x = 1
Thus;
y = (1 - 2)(1 + 4)
y = -5
x- and y-coordinates of the vertex of the graph are; (1, -5)
3) The y-intercept is the point at which x = 0. Thus;
y = 0² + 2(0) - 8
y = -8
The y-intercept is (0, -8).
