Step-by-step explanation:

Now the general equation of a moving object in a translational motion is given by;

S = ut + 1/2 at^2;

Where S- distance

a- acceleration

u- initial velocity

t- time

S = distance and in this case it would be Height 'H'

a= acceleration and in this case it will be 'g' acceleration due to gravity because the rocket would be under the influence of gravity.

When you substitute that you should be able to derive the expression for that of the quadratic equation.

And with the equation when you take values of x and substitute them in the expression above you get the values of h and you can then plot this point to form the graph.

Step-by-step explanation:

Answer:

area = 375.8 ft^2

Step-by-step explanation:

The scale is 2 inches = 5 feet.

The room is 6.5 inches wide in the drawing. We need the real width, x.

2 in./5 ft = 6.5 in./x

2x = 5 * 6.5

2x = 32.5

x = 16.25

The real width is 16.25 ft.

The room is 9.25 inches wide in the drawing. We need the real length, y.

2 in./5 ft = 9.25 in./y

2y = 5 * 9.25

2x = 46.25

x = 23.125

The real length is 23.125 ft.

Area of rectangle = length * width

area = 23.125 ft * 16.25 ft

area = 375.78125 ft^2

area = 375.8 ft^2

If they both eat 5/12 each, it means they would both eat;

5/12 + 5/12 = (5 + 5)/12 = 10/12 = 5/6 of a bar.

Answer:

5/12 per brother x 3/1 brothers = 15/12 chocolate bars ate so the brothers ate 15/12 chocolate bar because each brother ate 5/12 and there are 3 brothers so we multiply

Step-by-step explanation:

The equation of the parabola shaped arc is given as:

[tex]h =-0.00635x^2 +4.0005x -0.07875[/tex]

In a parabola, the line of symmetry divides the parabola into two equal parts.

Therefore, to find the distance from one base of the parabola to the other, we simply multiply the x-value at the line of symmetry by 2.

For a quadratic equation of the form [tex]y=ax^2+bx+c[/tex]:

Therefore, distance from one base of the arc  to the other

[tex]=-\dfrac{b}{2a} X 2\\\\=-\dfrac{b}{a}[/tex]

In our given equation:

[tex]a=-0.00635, b=4.0005\\$Therefore:Distance = $ -\dfrac{4.0005}{-0.00635}\\=630$ ft[/tex]

The distance from one base of the arc  to the other is 630 ft.

Find attached the diagram of the dot plot.

A measure of spread is used to describe the variation in a sample or data set. It is sometimes referred to as a measure of dispersion.

It is usually used together with the mean or median, to provide an overall description of a set of data.

There are two measures of spread: range and standard deviation. Range is the simplest in terms of calculation.

In this question, the range is used to determine the spread of the data set.

From the dot plot,

The range = the highest value - lowest value in a data set.

The highest value = 15

The lowest value = 10

Therefore the spread of the data in the dot plot is from 10 to 15 (B)

Probability = (required outcome / Total possible outcomes)

B) probability that a student studied(5 - 10 hours)

P(5 to 10 hours) = n(5 - 10 hours) / n(total) = 55/135 = 11/27

C) Find the probability that a student is a male and spends less than 5 hours studying

P(male and < 5 hours) = n(male ∩> 5 hours) / n(total) = 25/135 = 5/27

D) Find the probability that a student is a female or spends more than 10 hours studying.

P(female) + P(> 10hours) - P(Female ∩ > 10 hours) = 65/135 + 35/135 - 15/135 = 85/135 = 17/27

E.) Find the probability that a student spends more than 10 hours studying given that the student is a female?

n(Female ∩ > 10 hours) / n(Female)

15/65 = 3/13

F) Find the probability that a student is a male given that he spends less than 5 hours studying

n(male ∩ < 5hrs) / n(< 5 hours) = 25/ 45 = 5/9

THE WIDTH=67.5 feet & LENGTH=67.5+15=82.5 feet

Perimeter of a rectangle (A) is the 2× sum of of its length (l) and width (w).

A=2(l+ w)

Here, given that,

Perimeter=150 feet

Let, width be x

then, length be x +15

ATQ

x+x+15=150

2x+15=150

2x=150-15

2x=135

x=135/2

x=67.5 feet

Then:

WIDTH=67.5 feet

LENGTH=67.5+15

             =82.5 feet

Answer:

(60 - 4x)(50 + 2x) = 2,800

Step-by-step explanation:

Answer:

(1) The correct option is (B).

(2) The mean of the distribution of sample means is 19 fl. oz.

(3) The standard deviation of the distribution of sample means is 0.283 fl. oz.

(4) The correct option is (C).

Step-by-step explanation:

According to the Central Limit Theorem if we have a normal population with mean μ and standard deviation σ and a number of random samples are selected from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.

The mean of the sampling distribution of sample mean will be:

[tex]\mu_{\bar x}=\mu[/tex]

And the standard deviation of the sampling distribution of sample mean will be:

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]

The information provided is:

μ = 129

σ = 0.80

n = 8

(1)

The shape of the sampling distribution of sample mean will be Normal.

This is because the population from which the sample is selected is normal.

The correct option is (B).

(2)

Compute the mean of the distribution of sample means as follows:

[tex]\mu_{\bar x}=\mu[/tex]

    [tex]=129[/tex]

Thus, the mean of the distribution of sample means is 19 fl. oz.

(3)

Compute the standard deviation of the distribution of sample means as follows:

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]

    [tex]=\frac{0.80}{\sqrt{8}}\\\\=0.282843\\\\\approx 0.283[/tex]

Thus, the standard deviation of the distribution of sample means is 0.283 fl. oz.

(4)

Any change in the sample size will have no effect on the mean of the distribution of sample means.

But, if the sample is increased or decreased than the standard deviation will be decreased or increased respectively.

This is because the standard deviation of the distribution of sample means is inversely proportional to the sample size.

So, for n = 100 the standard deviation is:

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]

    [tex]=\frac{0.80}{\sqrt{10}}\\\\=0.282843\\\\\approx 0.08[/tex]

Thus, the standard deviation was decreased.

The correct option is (C).

Using the Central Limit Theorem, it is found that:

1. B. Normal.

2. The mean is of 129 fl. oz.

3. The standard deviation is of 0.283.

4. C. The standard deviation would decrease.

Item a:

Item b:

Item c:

Then:

[tex]s = \frac{0.8}{\sqrt{8}} = 0.283[/tex]

Item d:

The standard deviation is inversely proportional to the square root of the sample size, hence it would decrease, and option C is correct.
