Explain how you know 1 5/8 is a little grater than 1 1/2

Answers

Step-by-step explanation:

To find out that 1 5/8 is greater than 1 1/2, find common denominators.

Multiply 1/2 by 4:

4/8.


Let's compare:

1 5/8 > 1 4/8.

This is because 5 > 4.

Your answer: One numerator is smaller than the other, therefore making 1 5/8 greater.

There are 1,500 trees in a forest, of which 300 are oak trees. What percent, p, of the trees are oak trees? Complete the statement

Answers

Answer:

20 percent

Step-by-step explanation:

There are 20 percent of the trees in the forest are the Oak trees.

The percentage of oak trees,  p , in the forest can be calculated using the following formula:

p = Number of oak  trees/ Total number of trees x  100

Given that there are 300 oak trees out of a total of 1,500 trees in the forest.

Plugging these values into the formula:

p = (300)/ (1500) x 100

   = 1/5 x 100

   = 100/5

   = 20

So, 20% of the trees in the forest are oak trees.

14th term of geometric sequence 10,20,40

Answers

Answer: 81920


Explanation: The general formula for nth term in a geometric sequence is an=a1*r^(n-1), where a1 is the first term, r is the common ratio, and n is the position in the term (in this case 14).

To find the common ratio, we can simply divide the next term after the first (20/2=10).

So, an=10*2^(14-1).

After doing the parentheses and multiplication, we have 20^13, which is 81920.

An experimenter would like to construct a 99% confidence interval with a width at most 0. 5 for the average resistance of a segment of copper cable of a certain length. If the experimenter knows that the standard deviation of such resistances is 1. 55. How big a sample should the experimenter take from the population? what happens if the standard deviation and the width of the confidence interval are both doubled?.

Answers

A big sample that should the experimenter take from the population is 256 and if the standard deviation and the width of the confidence interval are both doubled then the sample is also 256.

In the given question,

The confidence level = 99%

Given width = 0.5

Standard deviation of resistance(\sigma)= 1.55

We have to find a big sample that should the experimenter take from the population and what happens if the standard deviation and the width of the confidence interval are both doubled.

The formula to find the a big sample that should the experimenter take from the population is

Margin of error(ME) \(=z_{\alpha /2}\frac{\sigma}{\sqrt{n}}\)

So n \(=(z_{\alpha /2}\frac{\sigma}{\text{ME}})^2\)

where n=sample size

We firstly find the value of ME and \(z_{\alpha /2}\).

Firstly finding the value of ME.

ME=Width/2

ME=0.5/2

ME=0.25

Now finding the value of \(z_{\alpha /2}\).

Te given interval is 99%=99/100=0.99

The value of \(\alpha\) =1−0.99

The value of \(\alpha\) =0.01

Then the value of \(\alpha /2\) = 0.01/2 = 0.005

From the standard table of z

\(z_{0.005}\) =2.58

Now putting in the value in formula of sample size.

n=\((2.58\times\frac{1.55}{0.25})^2\)

Simplifying

n=(3.999/0.25)^2

n=(15.996)^2

n=255.87

n≈256

Hence, the sample that the experimenter take from the population is 256.

Now we have to find the sample size if the standard deviation and the width of the confidence interval are both doubled.

The new values,

Standard deviation of resistance(\(\sigma\))= 2×1.55

Standard deviation of resistance(\(\sigma\))= 3.1

width = 2×0.5

width = 1

Now the value of ME.

ME=1/2

ME=0.5

The z value is remain same.

Now putting in the value in formula of sample size.

n=\((2.58\times\frac{3.1}{0.5})^2\)

Simplifying

n=(7.998/0.5\()^2\)

n=(15.996\()^2\)

n=255.87

n≈256

Hence, if the standard deviation and the width of the confidence interval are both doubled then the sample size is 256.

Answers

The crank angle value when the piston is at Top Dead Center (TDC) is 0 radians or 0 degrees. The maximum ratio of the crank radius to the connected length is 0.3.

The crank angle value refers to the angle between the crankshaft and a reference point when measuring the position of the piston. When the piston is at Top Dead Center (TDC), it is at its highest point in the cylinder. The crankshaft is positioned such that the connecting rod is aligned with the crank radius and the piston is at the topmost position. This corresponds to a crank angle value of 0 radians or 0 degrees.

Regarding the maximum ratio of the crank radius to the connected length, this value is given as 0.3. The crank radius is the distance from the center of the crankshaft to the center of the crank pin, and the connected length is the distance from the center of the crank pin to the center of the piston pin. The maximum ratio of 0.3 indicates that the crank radius is 0.3 times the connected length.

It's important to note that these values are specific to the context of the problem statement provided. Different engines or mechanisms may have different values for the crank angle at TDC and the maximum ratio of crank radius to connected length.

Translating algebraic language into normal language is always difficult to explain, but I'll try my best.

If I told you, "What is 65 less than 100", You would probably say 35. If I say, "I make 65 dollars less than you" Then we're taking your salary and decreasing it by 65 to find my salary. So we do take your salary/100 (n) and decrease it by my salary/65, and the operation for that is subtraction, so you would do n-65, and that difference will be 65 LESS than n.

when you use the 3 second following distance at rural road speeds (55 mph), compared to city driving speeds (25 mph), the distance you travel per second is

Answers

To find the distance traveled per second, we can use the formula:

Distance = Speed * Time

For rural road speeds of 55 mph, we need to convert the speed to miles per second.

Since there are 60 minutes in an hour and 60 seconds in a minute, we have:

Speed = 55 miles/hour * (1 hour / 60 minutes) * (1 minute / 60 seconds)

= 55 / (60 * 60) miles/second

≈ 0.01528 miles/second

So, at rural road speeds of 55 mph, you would travel approximately 0.01528 miles per second.

Now let's calculate the distance traveled per second at city driving speeds of 25 mph:

Speed = 25 miles/hour * (1 hour / 60 minutes) * (1 minute / 60 seconds)

= 25 / (60 * 60) miles/second

≈ 0.00694 miles/second

Therefore, at city driving speeds of 25 mph, you would travel approximately 0.00694 miles per second.

In summary, when using a 3-second following distance, you would travel approximately 0.01528 miles per second on rural roads (55 mph) and approximately 0.00694 miles per second in city driving (25 mph).

the gpa of accounting students in a university is known to be normally distributed. a random sample of 21 accounting students results in a mean of 2.88 and a standard deviation of 0.16. construct the 90% confidence interval for the mean gpa of all accounting students at this university.

Answers

We can say with 90% confidence that the true mean GPA of all accounting students at this university lies between 2.7107 and 3.0493.

We are given:

Sample size n = 21

Sample mean X = 2.88

Sample standard deviation s = 0.16

Confidence level = 90% or α = 0.10 (since α = 1 - confidence level)

Since the sample size is small and population standard deviation is unknown, we will use a t-distribution to construct the confidence interval.

The formula for the confidence interval is given by:

X ± t(α/2, n-1) * s/√n

where t(α/2, n-1) is the t-score with (n-1) degrees of freedom, corresponding to the upper α/2 percentage point of the t-distribution.

Using a t-table with (n-1) = 20 degrees of freedom and α/2 = 0.05, we find the t-score to be 1.725.

Plugging in the values, we get:

2.88 ± 1.725 * 0.16/√21

= (2.7107, 3.0493)

Therefore, we can say with 90% confidence that the true mean GPA of all accounting students at this university lies between 2.7107 and 3.0493.

Note: The confidence interval can also be written as [2.71, 3.05] rounding to two decimal places.

Pls help it’s for 20 point pls

Answers

The surface area of the cylinder is 314.6 square inches.

The surface area of a cylinder is given by the formula:

S.A. = 2πrh + 2πr²

Where r is the radius of the circular base of the cylinder and h is the height of the cylinder.

If we know the radius and height of a cylinder, we can easily calculate its surface area.

To solve for the surface area of the cylinder whose radius is 5 inches, we use the formula and substitute the values. The net of a cylinder whose radius of the base is labeled 5 inches and a rectangle with a height labeled 4 inches is given below:

Given the radius, r = 5 inches, height of cylinder, h = 4 inches.

Substituting the values in the formula:

S.A. = 2πrh + 2πr²

= 2 × 3.14 × 5 × 4 + 2 × 3.14 × 5²

Find the Taylor polynomial T3(x) for the function f(x) = ex sinx at a = 0. Use T3(x) obtained in part (A) to evaluate lim( e^x sinx?x?x^2) / x^3

Answers

To find the Taylor polynomial T3(x) for the function f(x) = ex sinx at a = 0, we can use the Taylor series expansion. The Taylor polynomial of degree 3 is given by:

\(T3(x) = f(0) + f'(0)x + (f''(0)/2!)x^2 + (f'''(0)/3!)x^3\)

First, let's find the derivatives of f(x):

f(x) = ex sinx

f'(x) = ex cosx + ex sinx

f''(x) = 2ex cosx

f'''(x) = 2ex cosx - 2ex sinx

Evaluate the derivatives at x = 0:

\(f(0) = e^0 sin(0) = 0\\f'(0) = e^0 cos(0) + e^0 sin(0) = 1\\f''(0) = 2e^0 cos(0) = 2\\f'''(0) = 2e^0 cos(0) - 2e^0 sin(0) = 2\)

Now, substitute these values into the Taylor polynomial formula:

\(T3(x) = 0 + 1x + (2/2!)x^2 + (2/3!)x^3\)

Simplifying:

\(T3(x) = x + x^2 + (1/3)x^3\)

Now, let's evaluate the limit:

\(lim(x- > 0) (e^x sinx / x^3)\)

We can use the Taylor polynomial T3(x) to approximate the function \(e^x sinx\)  as x approaches 0.

The term \(e^x sinx\) can be approximated as x when x is close to 0. Thus, as x approaches 0, the limit becomes:

\(lim(x- > 0) (x / x^3) = lim(x- > 0) (1 / x^2)\)

However, the limit of \(1 / x^2\)as x approaches 0 is infinity.

Therefore, the limit is infinity.

Please note that this is an approximation using the Taylor polynomial, and the actual behavior of the function may differ.

O converges O diverges

Answers

The given series can be analyzed using the Direct Comparison Test to determine its convergence or divergence. By comparing it with a geometric series, we can conclude that the given series converges.

To apply the Direct Comparison Test, we need to compare the given series with a known series whose convergence or divergence is already established. In this case, let's compare the given series ∑ (8^n / (9^n + 7)) with a geometric series ∑ (8^n / 9^n).

For all n ≥ 0, we have (8^n / (9^n + 7)) ≤ (8^n / 9^n). This is because adding a positive constant (7) to the denominator increases its value, making the fraction smaller.

Now, let's consider the geometric series ∑ (8^n / 9^n). This series is a convergent geometric series with a common ratio of 8/9 (which is less than 1), so it converges.

Since (8^n / (9^n + 7)) ≤ (8^n / 9^n) and the geometric series ∑ (8^n / 9^n) converges, by the Direct Comparison Test, we can conclude that the given series ∑ (8^n / (9^n + 7)) also converges.

In summary, the series ∑ (8^n / (9^n + 7)) converges.
