Find the GCF (30,45)

Answers

Hey there! I'm happy to help!

The Greatest Common Factor is self-explanatory: it is the largest factor that both numbers have in common. Let's look at the factors of each of these numbers:

30: 1, 30, 2, 15, 3, 10, 5, 6

45: 1, 45, 3, 15, 5, 9

We see that the largest number they both have in common is 15, so the GCF is 15.

Have a wonderful day! :D

15 because both of them are divisible by 15 and that’s the gcf

the crowd at a sporting event is estimated to be 2,500 people. the exact attendance is 2,486 people. what is the percentage error?

Answers

Answer:

0.56%

Step-by-step explanation:

Percentage error

[tex] = \frac{2500 - 2486}{2500} \times 100 \\ \\ = \frac{1400}{2500} \\ \\ = 0.56\%[/tex]

The crowd at a sporting event is estimated to be 2,500 people, the exact attendance is 2,486 people, the percentage error is, 0.56%

What is the percentage?

The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.

Formula for percentage;

Percentage = (present quantity/whole quantity)×100

Given that,

The crowd estimated to be 2,500 people

The exact attendance is 2,486 people

Percentage error = ?

Percentage error = (estimated value- exact value)/estimated value×100

Percentage error =   (2,500 - 2,486) /2500×100

                             =  0.56%

So, the percentage error is 0.56%

The distance y (in centimeters) a spring is compressed by a force x (in kilograms) is given by
y = 0.065x.
Complete a table of values for
x = 20, 40, 60, 80, and 100
to determine the distance the spring is compressed for each of the specified forces.

Answers

Answer:

(x, y) = {(20, 1.3), (40, 2.6), (60, 3.9), (80, 5.2), (100, 6.5)}

Graph C represents the table of values

Step-by-step explanation:

To complete the table, substitute each value of x into the equation, [tex] y = 0.065x [/tex], to find each corresponding y-value.

Thus:

✔️When x = 20:

[tex] y = 0.065x [/tex]

[tex] y = 0.065(20) [/tex]

[tex] y = 1.3 [/tex]

✔️When x = 40:

[tex] y = 0.065x [/tex]

[tex] y = 0.065(40) [/tex]

[tex] y = 2.6 [/tex]

✔️When x = 60:

[tex] y = 0.065x [/tex]

[tex] y = 0.065(60) [/tex]

[tex] y = 3.9 [/tex]

✔️When x = 80:

[tex] y = 0.065x [/tex]

[tex] y = 0.065(80) [/tex]

[tex] y = 5.2 [/tex]

✔️When x = 100:

[tex] y = 0.065x [/tex]

[tex] y = 0.065(100) [/tex]

[tex] y = 6.5 [/tex]

✔️The graph of that represents this table of values is graph C. See attachment.

Step 2: Solve for x

Subtract 1 on both sides:                    3x < 9Divide 3 on both sides:                       x < 3

Here we see that any value x smaller than 3 would work as a solution to the inequality.

Answers

Given:

Consider the completer question is "Find the derivative [tex]\dfrac{dy}{dx}[/tex] for [tex]y=\dfrac{x^2-4x}{x^3-5}[/tex]."

To find:

The derivative [tex]\dfrac{dy}{dx}[/tex].

Solution:

Chain rule: [tex]\dfrac{d}{dx}f(g(x))=f'(g(x))\cdot g'(x)[/tex]

Quotient rule: [tex]\dfrac{d}{dx}\dfrac{f(x)}{g(x)}=\dfrac{g(x)f'(x)-f(x)g'(x)}{[g(x)]^2}[/tex]

We have,

[tex]y=\dfrac{x^2-4x}{x^3-5}[/tex]

Differentiate with respect to x.

[tex]\dfrac{dy}{dx}=\dfrac{d}{dx}\left(\dfrac{x^2-4x}{x^3-5}\right)[/tex]

Using chain rule and quotient rule, we get

[tex]\dfrac{dy}{dx}=\dfrac{(x^3-5)\dfrac{d}{dx}(x^2-4x)-(x^2-4x)\dfrac{d}{dx}(x^3-5)}{(x^3-5)^2}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{(x^3-5)(2x-4)-(x^2-4x)(3x^2)}{(x^3-5)^2}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{2x^4-4x^3-10x+20-3x^4+12x^3}{(x^3-5)^2}[/tex]

[tex]\dfrac{dy}{dx}=\dfrac{-x^4+8x^3-10x+20}{(x^3-5)^2}[/tex]

Therefore, the required answer is [tex]\dfrac{dy}{dx}=\dfrac{-x^4+8x^3-10x+20}{(x^3-5)^2}[/tex].

A random sample of 100 felony trials showed a sample mean waiting time between arrest and trial = 173 days with a population standard deviation of waiting times = 28 days. Find a 99% confidence interval for the population mean waiting time. Stats question, I'm really struggling here. Please help me!

Answers

Answer: 165.78 < μ < 180.22

Step-by-step explanation: Confidence Interval of a mean is a method to estimate the true population mean, i.e., we can get an interval where the true mean exists.

A confidence interval is calculated as

x ± [tex]z\frac{\sigma}{\sqrt{n} }[/tex]

z is z-score for 99% confidence, which is: z = 2.58

Then, the estimate is

173 ± [tex]2.58\frac{28}{\sqrt{100} }[/tex]

173 ± 2.58*2.8

173 ± 7.224

lower limit: 173 - 7.224 = 165.78

upper limit: 173 + 7.224 = 180.22

The 99% confidence interval of the mean is between 165.78 and 180.22 and it means that the true mean of this population is between those numbers with 99% of confidence.
