The constant of proportionality of the given linear graph is; 3/5

The constant of proportionality is defined as the ratio of two proportional values that is said to be in a constant value.

Now, in this case where we have a graph, the constant of proportionality is equivalent to the slope of the graph.

The slope will be gotten using two coordinates (x₁, y₁) and (x₂, y₂) with the formula;

m = (y₂ - y₁)/(x₂ - x₁)

Let us use two coordinates on the graph (0.5, 0.3) and (1, 0.6)

m = (0.6 - 0.3)/(1 - 0.5)

m = 0.3/0.5

m = 3/5

The final cost of a skateboard after all the discounts and reductions is $53.775.

Given that, during a clearance sale at a sporting goods store, skateboards were marked down 30%. On Saturday, an additional 25% was taken off already reduced prices of skateboards.

We need to find the final price after all discounts had been taken.

What is the discount?

The basic way to calculate a discount is to multiply the original price by the decimal form of the given percentage rate. To calculate the sale price of any item, we need to subtract the discount from the original price.

Given, that the original cost of the skateboard is $119.50.

Now, 30+25=55

So, the total decrease in percentage is 55%.

The final cost of a skateboard=119.50-55% of 119.50

=119.50-0.55 × 119.50

=119.50-65.725

=$53.775

Therefore, the final cost of a skateboard after all the discounts and reductions is $53.775.

The slope of line is -3,  the equation of line is y=-3x+2 and the graph is not proportional.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.

The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is

m=y₂-y₁/x₂-x₁

From the given graph let us take two points (0, 5) and (1,2).

m=2-5/1=-3.

Now let us find the y intercept.

2=-0+b

2=b

So the equation of line is y=-3x+2.

As the graph is not passing through the origin, then the graph is not proportional.

Hence, -3 is the slope of line and  y=-3x+2 is the equation of line and the graph is not proportional.

The correct part is (d) i.e. Fail to reject the null hypothesis.

What is hypothesis testing?

By evaluating whether or not the observed test statistic is more extreme than would be anticipated if the null hypothesis were true, the critical value approach determines whether something is "likely" or "unlikely." This means that the alternative hypothesis is accepted in place of the null hypothesis when the observed test statistic is more extreme than a cutoff number, known as the "critical value." The null hypothesis is not disproved if the test statistic does not deviate significantly from the crucial value.

Here, The critical value is 1.6257 and the sample's test statistic value is 1.3994.

We can see that the sample's test statistic value is not extreme as the critical value, So the null hypothesis should not be rejected.

Hence, It fails to reject the null hypothesis.

Answer: To answer this question, we need to perform a hypothesis test. The null hypothesis is that the standard deviation of the process is 2 mg or less, and the alternative hypothesis is that the standard deviation of the process is over 2 mg.

To test this hypothesis, we need to calculate the test statistic, which is the z-score. The z-score tells us how many standard deviations a given data point is from the mean. In this case, the z-score is calculated by subtracting the mean of the sample from the hypothesized mean of the population, and dividing that difference by the standard deviation of the sample:

z = (20.2 - 20) / 2.4 = 0.1

Since the z-score is positive, we know that the mean of the sample is greater than the hypothesized mean of the population. However, we need to compare this z-score to the critical value to determine whether it is statistically significant.

The critical value is the z-score that marks the cutoff between the region of acceptance and the region of rejection of the null hypothesis. For a 1% level of significance, the critical value is the z-score that marks the 99th percentile of the normal distribution. Since the normal distribution is symmetrical, this means that the critical value is 2.58 standard deviations from the mean.

Since the z-score we calculated is less than the critical value, we cannot reject the null hypothesis. This means that we cannot assert that the standard deviation of the process is over 2 mg at a 1% level of significance.

The required step to be taken is to factor the trinomial in the derivation.

The general form of a quadratic equation is given as ax^2 + bx + c = 0.

Here, a ≠ 0 and b and c are integers.

The degree of a quadratic equation is 2.

It can be factorized by completing square method.

The given problem can be solved as follows,

The derivation made by Jimmy is given as,

ax² + bx + c = 0

=> x² + (b/a)x + c/a = 0

=>  x² + (b/a)x =  -c/a

=> x² + (b/a)x + (b/2a)² = -c/a + (b/2a)²

Now, in order to solve the equation the trinomial on the LHS can be factored as follows,

(x + b/2a)² = -c/a + (b/2a)²

The function and the estimated value for the given population of fox are obtained as P(t) = P₀(1 + r)^t and 35346 respectively.

In order to model the population growth first find the value of the growth rate then substitute it into the expression P(t) = P₀(1 + r)^t.

Now, the value of P₀ can be found for t = 0 and thus the function is obtained.

The given problem can be solved as follows,

(a) The population of fox in year 2000 is given as 25800.

And, the growth rate is 4%.

Suppose t = 0 for year 2000.

And for some value of t, the population is P(t).

Now, the following expression for the population can be written as,

P(t) = P₀(1 + r)^t

Where P₀ is the population at the year 2000.

Thus, the expression can be written as,

P(t) = 25800(1 + 4/100)^t

(b) In the year 2008, the value of t is 8.

Substitute t = 8 in the expression of the population to get,

P(t) = 25800(1 + 4/100)^8

⇒ 25800 × 1.37

What is end behavior of polynomial?

A polynomial function typically behaves at its end in the same way that its leading term, or the term with the largest exponent, does at its end.

Look at the leading term of the polynomial function to understand its end behavior. Given that the leading term has the highest power, its behavior will dominate the graph because it will grow much more quickly than the other terms as x gets very large or very small.

Consider, the given polynomial g(x) = x^2 (6 - x)

From the graph of the polynomial function we can see that the maximum point of the polynomial is at its vertex.

Modified Euler's method is a numerical method used to solve ordinary differential equations (ODEs). It is a variation of Euler's method that is more accurate than the original, but still relatively simple to implement. It works by taking a single iteration of the Euler method, then using the midpoint between the current and previous points to calculate the next point in the sequence. This is done in order to reduce the error.

Solution

We have, y(0) = 0

dy/dt = 1 – y

h = 0.1

Using modified Euler's method,

y(0.1) = y(0) + (1/2) h (f(t0, y0) + f(t0 + h, y0 + hf(t0, y0)))

= 0 + (1/2) (0.1) [(1 - 0) + (1 - 0 + 0.1)]

= 0.05

Similarly,

y(0.2) = 0.1 + (1/2) (0.1) [(1 - 0.05) + (1 - 0.1 + 0.1)]

= 0.0975

Answer:

Step-by-step explanation:

You want the solution to scalene triangle ABC with AC = 23, BC = 15, and ∠A = 40°.

When two sides of a triangle are given, along with an angle not between them, the Law of Sines can be used to solve the triangle. It tells you ...

  sin(B)/AC = sin(C)/AB = sin(A)/BC

When the given angle is opposite the shortest given side, there are generally 2 solutions.

  sin(B)/23 = sin(40°)/15 . . . . . fill in given values to find angle B

  B = arcsin(23/15·sin(40°)) = 80.3° or 99.7°

Angle C will have the value that makes up the difference from 180°:

  C = 180° -40° -{80.3°, 99.7°} = {59.7°, 40.3°}

The length of side AB can be found using the same Law of Sines proportion:

  AB = BC·sin(C)/sin(A) = 15/sin(40°)·sin({59.7°, 40.3°})

  AB = {20.2, 15.1}

The solutions are ...

Arguably, the second solution is not a "scalene" triangle. It is (nearly) isosceles. (See the comment below.)

Since answers are requested to be rounded to tenths, both solutions are scalene triangles. If we rounded to integers, then only the first solution would be a scalene triangle.

The correct proportion used to prove that HJ || KL is [tex]\frac{GK}{HK} = \frac{GL}{LJ}[/tex].

What is the proportion theorem of two similar lines?

According to this theorem, if you draw a line parallel to one side of a triangle that divides the other sides into two separate points, the line will proportionally divide the other sides. In addition, a line is parallel to the third side if it divides any two triangle sides in the same ratio.

We have,

HJ || KL

If a line parallel to one side of a triangle intersects the other two sides of the triangle, then the line divides these two sides proportionally.

And in the given triangle,  HJ is parallel to KL, So HJ divided the two sides in proportion, that is

[tex]\frac{GK}{HK} = \frac{GL}{LJ}[/tex]

The correct option is the fourth option.

Step-by-step explanation: If the drama class sold 20 more adult tickets than student tickets to the fall play, and adult tickets cost $8, then the number of adult tickets sold can be calculated by adding 20 to the number of student tickets sold and multiplying by $8. We can set up an equation to represent this relationship, where A represents the number of adult tickets sold and S represents the number of student tickets sold:

A = S + 20

A * 8 = $880

We know that the total amount collected from ticket sales was $880, and we know that adult tickets cost $8, so we can divide $880 by $8 to find the number of adult tickets sold:

A = $880 / $8

A = 110

Therefore, the drama class sold 110 adult tickets to the fall play.
