15 green marbles are there among 56 marbles.

A bag contains 56 marbles, so Total marbles =56.

In That, There are Green and red marbles contained in a ratio of 3:4.

Now we have to assume that

Let 3x = the number of green marbles and 4x = the number of red marbles

By using the ratios and the total we can know how many green and red marbles are there in a bag. so the formula is:

ax+bx=t-------(1)

a and b are ratios of given marbles

t is the total number of marbles

x is to find the value

substituting the values in the above equation we get

3x + 4x =35

7x = 35

x = 5

substitute the x value in 3x we get:

Green: 3x = 15

Therefore,15 green marbles are present among 56 marbles

An equation that has the highest degree of 1 is known as a linear equation. This means that no variable in a linear equation has an exponent more than 1. The graph of a linear equation forms a straight line.

A linear equation can have one or two variables. For example 5 = y+ 3y is an example of linear equation with one variable and y = 5 +3x is an example of linear equation with two variables.

8x-4= 2(4x+1)-6

The following are the actions she could take to solve the quadratic equation: 2(x² + 6x + 9) = 18 + 3.

Following is the determination of the quadratic equation's solution;

2x² + 12x - 3 = 0

2x² + 12x = 3

Divide equation by 2.

x² + 6x = 3/2

Add both of the equation's sides after squarely multiplying the x-coefficient by half:

(x + 3)² = 3/2 + 3²

x² + 6x + 9 = 9 + 3/2

2(x² + 6x + 9) = 18 + 3

a) The function in vertex form is; y = -16(x - 3.5)² + 198

b) The maximum height if the arrow is; 198 feet

c) The time that it takes the arrow to hit the ground is; 16 seconds

We are given the function as;

y = -16t² + 112t + 2.

where;

y is the height (in feet) of an arrow

t is the time in seconds after it is shot from a bow

This is the equation of a vertical parabola open downward

The vertex is a maximum

The general form of a  quadratic equation in vertex form is;

y = a(x - h)² + k²

where (h, k) is the vertex coordinate

a) y = -16t² + 112t + 2

This is in standard form and using completing the square, we can write in vertex form as;

y = -16(x - 3.5)² + 198

b) The vertex is the point (3.5, 198)

The maximum height of the arrow represents the y-coordinate of the vertex of the function

Thus, the maximum height of the arrow is 198 feet

c) We know that when the arrow hits the ground, the value of y is equal to zero. Thus, at y= 0, we have;

-16(x - 3.5)² + 198 = 0

Rearranging gives;

(x - 3.5)² = (198/16)

(x - 3.5) = ±√(198/16)

(x - 3.5) = ±12.375

x = 12.375 + 3.5

x = 15.875 ≈ 16 seconds which is the time it will take to hit the ground.

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.

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

There are several ways to write an equation for the money collected as a function of the number of t-shirts sold. One possible equation is $y = x \cdot p$, where $p$ is the price of each t-shirt. This equation says that the total amount of money collected is equal to the number of t-shirts sold multiplied by the price of each t-shirt.Another possible equation is $y = p \cdot (x - c)$, where $c$ is the cost of producing each t-shirt. This equation says that the total amount of money collected is equal to the price of each t-shirt multiplied by the number of t-shirts sold minus the cost of producing each t-shirt.These are just two examples of how to write an equation for the money collected as a function of the number of t-shirts sold. The exact equation will depend on the specific details of the situation.

The end behavior of the polynomial is, rises to the left and falls to the right.

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.

The vertex of the polynomial is (10, 90).

So this is the maximum value of the function is (10, 90).

Now to find the end behavior of the polynomial.

The degree of the polynomial is 3 and the leading coefficient of the polynomial is, -1.

By using: Odd degree and Negative leading coefficient the graph Rises to the left and falls to the right.

Hence, the end behavior of the polynomial is, rises to the left and falls to the right.

The snow melted in 3 hours would be 1.5 inches, and the expression which represents the amount of snow left after 't' hours of snow melting S(t) = 12.5 - 0.5t

What is a constant rate of change?

A rate of change is a rate that describes how one quantity changes in relation to another quantity.

Constant rate is also called uniform rate which involves something traveling at a fixed and steady pace or else moving at some average speed.

The snow started melting at a rate of 0.5 inches per hour and it is known that 3 hours after the storm ended, the depth of snow was down to 11 inches.

Snow melted in 3 hours = 0.5 * 3 = 1.5 inches

Thus;

The Initial depth of snow = 11 + 1.5 inches = 12.5 inches.

Now, depth of snow on Gabriella's lawn = Initial depth - 0.5(Number of hours)

Let S(t) be the depth of snow on  Gabriella's lawn, in inches, t hours after the snow stopped falling.

Hence, the snow melted in 3 hours would be 1.5 inches, and the expression which represents the amount of snow left after 't' hours of snow melting S(t) = 12.5 - 0.5t

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

⇒ 35346

Hence, the function that models the population and the estimated population for year 2008 are given as P(t) = P₀(1 + r)^t and 35346 respectively.
