Answer: $5400
Step-by-step explanation:
x = amount raised so far
13500 - x = amt. still needed
x/3 = (13500 - x)/2
2x = 3(13500 - x)
2x = 40500 - 3x
5x = 40500
x = 40500/5 = 8100 (amt. raised so far)
13500 - 8100 = 5400 (amt. still needed)

If a polynomial f\mathopen{}\mathclose{\left(x\right)}f(x) has a remainder of 22 when divided by x-6x−6, what is f\mathopen{}\mathclose{\left(6\right)}f(6)?\
f\mathopen{}\mathclose{\left(6\right)}f(6) = (6-6)(something) + 22 = 0(something) + 22 = 22 which has a remainder of 22 when divided by x-6x-6. f\mathopen{}\mathclose{\left(6\right)}f(6) = \boxed{22}.
What is the remainder theorem?The remainder theorem states that when a polynomial is divided by a linear term, the remainder equals the value of the polynomial at the root of the linear term. This theorem may be used to determine the roots of a polynomial by dividing it by a linear term and solving for the remainder. For instance, when the polynomial x3+x2-5x+6 is divided by (x2), the result is identical to the polynomial's value at x=2. After finding the remainder, we may determine that the polynomial's root is 2, which we can do by solving for the remainder. This theorem may also be used to discover the roots of higher degree polynomials by combining linear terms.
How to solve?
f\mathopen{}\mathclose{\left(x\right)}f(x) can be written as (x-6)(something) + 22.
f\mathopen{}\mathclose{\left(6\right)}f(6) = (6-6)(something) + 22 = 0(something) + 22 = 22.
Therefore, f\mathopen{}\mathclose{\left(6\right)}f(6) = \boxed{22}.

The high school a athletic director is asked if football players are doing as well as academically asthe other students athletes. We know from a previous study that the average GPA for the student athletes is 3.10. after an initiative to help improve the GPA of students athletes, the athletic director randomly samples 20 football players and finds that the average GPA of the sample is 3.18 with a sample standard deviation of 0.54 is there a significant improvement use a 0.05 significance level
The athletic director can therefore draw the conclusion that the average academic standing of football players is comparable to the average standing of other student athletes.
Explain the term t-distribution?Whenever the population's standard deviation is unknown and the data come from such a normally distributed population, the t-distribution characterizes the standardized distances between the sample means and the population mean.The following formula is used to determine the test statistic:
SRS, s = 0.54, n = 40 > 30,
x = 3.18
H0: μ = 3.10
H1: μ > 3.10
α = 0.05
The t-distribution table and our alpha level of.05 are then used to determine our crucial values.
Our critical values are 2.093 for a two specimens with 19 levels of freedom and α = 0.05 level of significance.
t = x - μ / s/√n
t = 3.18 - 3.10/ 54/√20
t = 0.66
This indicates that the measured sample mean of football players, 3.18, is 0.66 standard errors higher than the 3.10 number that was predicted. We are unable to disprove the null hypothesis because the test statistic's value is below the threshold of 2.093.As a result, It is clear that sampling error is the only possible explanation for the discrepancy between both the sample mean as well as the hypothesized value.

If a publisher of nontechnical books takes great pains to ensure that its books are free of typographical errors the probability of any given page containing at least one such error is 0.005 and errors are independent of the page-to-page. What is the probability that one of its 400-page novels will contain exactly one page with errors? At most three pages with errors?
Part A: Probability that one of 400-page novels will have exactly one error-free page is 24.06%.
Part B.) No more than three pages contain errors: 40.06%.
Explain the term binomial distribution?The possibility that a value would take one among two independent values given a particular combination of factors or assumptions is summarized by the statistical distribution known as the binomial distribution.The given data in the question-
X has a binomial distribution that includes,400 pages make up the novel's page count.Error probability p = 0.005Probability of error-free page q = 01 - 0.005 = 0.995The following is the probability mass function (PMF) for X:
P(X = x) = ⁿCₓ . pˣ . qⁿ⁻ˣ
Part A.) One of 400-page novels will have exactly one error-free page.
P(x = 1) = ⁿCₓ . pˣ . qⁿ⁻ˣ
n = 400, x = 1
P(x = 1) = ¹⁰⁰C₁ . (0.005)¹ . (0.995)¹⁰⁰ ⁻ ¹
P(x = 1) = 0.2706
Thus, probability that one of 400-page novels will have exactly one error-free page is 24.06%.
Part B.) No more than three pages contain errors.
P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
P(x = 0) = ¹⁰⁰C₀ . (0.005)⁰ . (0.995)¹⁰⁰ ⁻ ⁰
P(x = 0) = 0.01346
P(x = 1) = ¹⁰⁰C₁ . (0.005)¹ . (0.995)¹⁰⁰ ⁻ ¹
P(x = 1) = 0.0270
P(x = 2) = ¹⁰⁰C₂ . (0.005)² . (0.995)¹⁰⁰ ⁻ ²
P(x = 2) = 0.00068
P(x = 3) = ¹⁰⁰C₃ . (0.005)³ . (0.995)¹⁰⁰ ⁻ ³
P(x = 3) = 0.0000027
Thus, P(x ≤ 3) = P(x = 0) + P(x = 1) + P(x = 2) + P(x = 3)
P(x ≤ 3) = 0.01346 + 0.00068 + 0.00068 + 0.0000027
P(x ≤ 3) = 0.4060021
Consequently, the likelihood of at maximum three pages having typographical errors is 40.06%.

The concept of algebraic expressions is the use of letters or alphabets to represent numbers without providing their precise values. We learned how to express an unknown value using letters like x, y, and z in the fundamentals of algebra. Here, we refer to these letters as variables. Variables and constants can both be used in an algebraic expression. A coefficient is any value that is added before a variable and then multiplied by it.
It is given that Becky has passed 4 scales, whereas her friend Charlotte has passed 8 of them.
Going forward, Becky has committed to passing 4 scales per week, and Charlotte has committed to passing 2 per week.

The vertices of triangle ABC are A(−4, 3), B(4, 3), and C(−4, −6). The triangle is dilated with a scale factor of 3. Estimate the perimeter of the dilated figure to the nearest whole number.
The perimeter of the image of the triangle is approximately equal to 87 units.
How to determine the perimeter of the image of a triangle
In this problem we find the coordinates of the vertices of a triangle: A(x, y) = (- 4, 3), B(x, y) = (4, 3), C(x, y) = (- 4, - 6), of which we must determine the perimeter of its image, which is the result of a scale factor of 3. The perimeter is the sum of the lengths of the triangle. The length of each side of the image of the triangle can be found by Pythagorean theorem and definition of dilation:
l = √[(Δx)² + (Δy)²]
Where:
l - Side lengthΔx - Change in the x-direction.Δy - Change in the y-direction.And the perimeter of the image of the triangle is described below:
p = k · (AB + BC + AC)
Where k is the scale factor.
First, determine the lengths of sides AB, BC and AC:
Side AB
AB = √[[4 - (- 4)]² + (3 - 3)²]
AB = 8
Side BC
BC = √[(- 4 - 4)² + (- 6 - 3)²]
BC = √[(- 8)² + (- 9)²]
BC = √145
Side AC
AC = √[(- 4 - 4)² + (- 6 - 3)²]
AC = 9
Second, determine the perimeter of the image:
p = 3 · (8 + √145 + 9)
p = 3 · (17 + √145)
p = 51 + 3√145
p ≈ 87.125

A surveyor makes the measures indicated in Fig. 19-71. For the figure, angle A = 34o and the Hypotenuse c = 159 ft. Note the angles are named with Capital Letters A, B, and C and the names or the sides opposite the angles are named with small letter
All parts of the triangle should be solved The parts of the triangle to include in the Problem Solution are: (1) degrees of all 3 angles A, B and C, (2) lengths of the two legs a, b , rounded to the nearest whole number, (3) length of the hypotenuse and (4) the area of the triangle with the proper units. That is 7 answers total.
The side lengths of the triangle are 89 ft, 132 ft and 159 ft
The angles of the triangle are 34 degrees, 56 degrees and 90 degreesThe area of the triangle is 5874 square unitsThe sides of the triangleThe given parameters are
Angle, A = 34 degrees
Hypotenuse = 159 ft
The length BC is calculated as
sin(A) = BC/Hypotenuse
So, we have
BC = Hypotenuse * sin(A)
This gives
BC = 159 * sin(34 degrees)
Evaluate
BC = 89 ft
The length AC is calculated as
cos(A) = AC/Hypotenuse
So, we have
AC = Hypotenuse * cos(A)
This gives
AC = 159 * cos(34 degrees)
Evaluate
AC = 132 ft
The angles for the triangleHere, we have
Angle, A = 34 degrees
Because the triangle is a right triangle, we have
Angle, C = 90 degrees
The sum of angles in a triangle is 180
So, we have
Angle B = 180 - 90 - 34
Angle B = 56
The area of the triangleThis is calculated as
Area = 0.5 * BC * AC
So, we have
Area = 0.5 * 89 * 132
Evaluate
Area = 5874

Find the area of the shaded region. Round to the nearest tenth. All polygons are regular.
Check the picture below.
let's take a looksie at that, notice, if we split the circle into 6 even pieces, we end up with six 60° angles at the center, namely six equilateral triangles as you see there.
now, if we run a dashed line as you see from a corner to the other to make the flatter triangle which is shaded, we end up cutting the equilateral triangle into two equal halves, each with 30° and 30° angles, because the dashed line intercepts the green line at 90°.
well, the flatter triangle from corner to corner, is spanning over two equilateral triangles, if it's owning half of one, it must be also owning half of the other. What the dickens does that mean? well, it means the area of the flatter triangle that's shaded, is really the same area as a "whole" of one of those equilateral triangles.
