y=1/3x+4 is the equation of line passing through (3, 5) and parallel to -x+3y=6

What is Slope of Line?

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

-x+3y=6

3y=6+x

Divide both sides by 3

y=2+1/3x

y=1/3x+2

slope is 1/3

In parallel lines the slope will remain same

We need to find the equation of line passing through (3, 5) and parallel to 3y=6+x

5=1/3(3)+b

5=1+b

b=4

Hence, y=1/3x+4 is the equation of line passing through (3, 5) and parallel to -x+3y=6

Answers

The American adults who believes in alien as per given 95% of confidence interval and the given sample surveyed is in the range of

( 0.657 , 0.783 ).

As given in the question,

Number of American adults surveyed (sample size) 'n' = 200

Percentage of people who believes in aliens 'p'= 72%

                                                                               = 0.72

Percentage  of people who don't believes in aliens ' 1 - p'  = 1 - 72%

                                                                                                 = 28%

                                                                                                 = 0.28

95% Confidence interval that represents percent of people believes in aliens

Z - score of 95% confidence interval = ± 1.96

Margin of error = (z-score)√p ( 1- p) /n

                          = ( 1.96)√(0.72 × 0.28)/ 200

                          = 1.96 ( 0.032)

                          = 0.06272

                          = 0.063

Lower limit = p - Margin of error

                  = 0.72 - 0.063

                  = 0.657

Upper limit =  p + Margin of error

                  = 0.72 + 0.063

The measure of ∠JKM is 145°.

What is exterior angle theorem?

The measure of an exterior angle of a triangle is bigger than either of the measures of the distant interior angles, according to the external angle theorem, Proposition 1.16 in Euclid's Elements.

Because the parallel postulate is not required for its proof, this is a fundamental conclusion in absolute geometry. Three of a triangle's corners are its vertices.

Two angles are produced by a triangle's sides (line segments) meeting at its apex (four angles if you consider the sides of the triangle to be lines instead of line segments). An interior angle of the triangle is the only one of these angles that has the third side of the triangle inside of it.

Here it is given that, ∠JLK= 70°

                                 ∠LJK = x°

(2x-5)°= 70°+x°

now applying exterior angle theorem,

x=75°

substitute 75 for x in 2x-5 to find m∠JKM.

=2x-5

=2×75-5

=145°

Hence, The measure of ∠JKM is 145°

10 post hole that are 3 feet deep and 1 foot across with a pipe down the center that is 3 inches in diameter

Answers

The total volume of all 10 holes and pipes is about 24.135 cubic feet.

What is Volume?

Generally, To calculate the volume of the holes, you can use the formula for the volume of a cylinder:

Volume = π * radius^2 * height

In this case, the radius of the hole is 0.5 feet (since the hole is 1 foot across and the diameter of the pipe is 3 inches, which is 0.25 feet), and the height is 3 feet. Plugging these values into the formula, we get:

Volume = π * 0.5^2 * 3 = 0.785 * 3 = 2.355 cubic feet

So each hole has a volume of about 2.355 cubic feet. To find the total volume of all 10 holes, you can simply multiply this number by 10:

Total volume = 2.355 * 10 = 23.55 cubic feet

This is the volume of the holes themselves, not including the volume of the pipes. To find the volume of the pipes, you can use the same formula, but with the radius of the pipe (which is 1.5 inches, or 0.125 feet) and the length of the pipe (which is 3 feet).

Volume = π * 0.125^2 * 3 = 0.0195 * 3 = 0.0585 cubic feet

So the volume of one pipe is about 0.0585 cubic feet. To find the total volume of all 10 pipes, you can multiply this number by 10:

Total volume = 0.0585 * 10 = 0.585 cubic feet

23.55 + 0.585 = 24.135 cubic feet.

What transformations were applied to the parent function k(x)=x| to obtain f(x)= -1/2|x+3/-1.​

Answers

Answer:

The transformations applied to the parent function k(x)=x| to obtain f(x)= -1/2|x+3/-1 are reflection in the y-axis, vertical stretching by a factor of 1/2, and a horizontal shift of 3 units to the right.

Step-by-step explanation:

To obtain f(x) from k(x), we first reflect k(x) in the y-axis, which changes the sign of the function and flips it over the x-axis. This gives us -k(x). Next, we vertically stretch the graph of -k(x) by a factor of 1/2. This makes the graph of -k(x) taller and narrower. Finally, we shift the graph of -k(x) 3 units to the right. This moves the entire graph 3 units to the right on the x-axis. The resulting function is f(x)=-1/2|x+3/-1.To understand why these transformations were applied, it's helpful to consider the effect of each transformation on the graph of k(x)=x|. Reflecting in the y-axis flips the graph over the x-axis and changes the sign of the function, so it becomes -k(x). Vertical stretching by a factor of 1/2 makes the graph of -k(x) taller and narrower. Finally, shifting the graph of -k(x) 3 units to the right moves the entire graph 3 units to the right on the x-axis. This results in the graph of f(x)=-1/2|x+3/-1.

Answer:

(Assuming it is k(x) = |x| and f(x) = -1/2|x+3| -1

Scale vertically by a factor of -1/2

Shift left 3

Shift down 1

Step-by-step explanation:

The -1/2 is multiplied by everything, so it scales the graph vertically by -1/2. The -1 is again, everything(as opposed to just modifying the x), so it shifts the graph down by 1.

The + 3 is a little more confusing. Basically, x would have to be x-3(which is shifting the graph left) in order to retain the same x-value(to make the equation true) for the same value. This is the same for y, but we usually isolate y so it doesn't come up as often. If we add 1 to both sides, we get [tex]f(x) + 1= -1/2|x+3|[/tex], and for the same reasoning the graph would shift down 1 even though it is f(x) + 1, because for the same x-value the y-value would need to be 1 less to make the equation to hold true.

The given scenario can be modelled as an exponential equation.

Let y be the area the fire covers (in meters squared).

Let x by the time (in hours).

If the fire currently covers an area of 32 m² then the initial value, a, is 32.

If the area covered by the fire increases by 17% each hour, then the growth factor, b, is 1.17 (since an increase of 17% is 117% of the previous amount).

Therefore:

a = 32b = 1.17

Substitute the values of a and b into the exponential formula:

[tex]y=32(1.17)^x[/tex]

To find the area that the first covers in 20 hours' time, simply substitute x=20 into the equation:

[tex]\implies y=32(1.17)^{20}[/tex]

[tex]\implies y=32(23.1055991...)[/tex]

[tex]\implies y=739.37917...[/tex]

Therefore, the area the fire will cover in 20 hours' time is 739 m²  (nearest 1 m²).

[tex]n=\frac{\left(z_\alpha+z_s\right)^2 \sigma^2}{(x-\mu)^2}[/tex]

The true mean for this case is [tex]$\mu=44$[/tex] and we want [tex]$\beta < 0.1$[/tex] so then [tex]$z_{1-0.1}=z_{0.9}=1.29$[/tex] represent the value on the normal standard distribution that accumulates 0.1 of the area on the right tail. And we can replace like this:

e) For this case we can calculate a one sided confidence interval given by:

And the confidence interval would be [tex]$(-\infty, 41.152)$[/tex]

And since 40 is on the confidence interval we don't have enough evidence to reject the null hypothesis on this case.

What is null hypothesis?

In a scientific setting, a hypothesis (plural: hypotheses) is a testable claim about the relationship between two or more variables or a suggested explanation for a phenomenon that has been observed.

Part a

We have the following data given:

n=10 represent the sample size

[tex]$\bar{x}=40.5$[/tex] represent the sample mean

[tex]$\sigma=1.25$[/tex]represent the population deviation.

We want to test the following hypothesis:

Null: [tex]$\mu \leq 40$[/tex]

Alternative: [tex]$\mu > 40$[/tex]

The significance level provided was [tex]$\alpha=0.05$[/tex]

The statistic for this case since we have the population deviation is given by:[tex]z=\frac{\bar{x}-\mu}{\frac{-\mu}{\sqrt{n}}}$[/tex]

If we replace the values given we got:

[tex]$z=\frac{40.5-40}{\frac{1.24}{\sqrt{10}}}=1.265$[/tex]

Now we can calculate the p value since we have a right tailed test the p values is given by:

[tex]p_v=P(Z > 1.265)=1-P(Z < 1.265)=1-0.897=0.1029[/tex]

And since the [tex]$p_v > \alpha$[/tex] we have enough evidence to FAIL to reject the null hypothesis. So then there is not evidence to support the claim that the mean is greater than 40 .

Part b

The p value on this case is given by:

[tex]p_v=P(Z > 1.265)=1-P(Z < 1.265)=1-0.897=0.1029[/tex]

Part c

For this case the probability of type II error is defined as the probability of incorrectly retaining the null hypothesis and is defined like this:

[tex]\beta=P\left(Z < z_\alpha-\frac{(x-\mu) \sqrt{n}}{\sigma}\right)[/tex]

Where [tex]$z_\alpha=1.645$[/tex]represent the critical value for the test that accumulates 0.05 of the area on the right tail of the normal standard distribution.

The true mean on this case is assumed [tex]$\mu=42$[/tex], so then we can replace like this:

[tex]\beta=P\left(Z < 1.645-\frac{2 \sqrt{10}}{1.25}\right)=P(Z < -3.409)=0.000326$$[/tex]

Part d

We want to ensure that the probability of error type II not exceeds 0.1, and for this case we can use the following formula:

[tex]n=\frac{\left(z_\alpha+z_\beta\right)^2 \sigma^2}{(x-\mu)^2}[/tex]

The ture mean for this case is [tex]$\mu=44$[/tex] and we want [tex]$\beta < 0.1$[/tex] so then [tex]$z_{1-0.1}=z_{0.9}=1.29$[/tex] represent the value on the normal standard distribution that accumulates 0.1 of the area on the right tail. And we can replace like this:

[tex]n=\frac{(1.65+1.29)^2 1.25^2}{(44-40)^2}=0.844 \approx 1[/tex]

Part e

For this case we can calculate a one sided confidence interval given by:

[tex]\left(-\infty, \bar{x}+z_\alpha \frac{\sigma}{\sqrt{n}}\right)[/tex]

And if we replace we got:

[tex]40.5+1.65 \frac{1.25}{\sqrt{10}}=41.152[/tex]

And the confidence interval would be [tex]$(-\infty, 41.152)$[/tex]

Set = 20 {10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200}

The set that can be divided by 15 is

Set = 6 {30, 6,0 90, 120, 150, 180}

So, the percentage of those integers that are multiples of 15 will be

⇒ 6 / 20

⇒ 3/10

3/10 will be the proportion of those integers that are multiples of 15. Then, C is the best choice.

What does the term "compound interest" mean?

Compound interest is when you receive interest on both your interest income and your savings.

You start with a one cent.

You have $0.01 x 2 the following day.

You have $0.01 x 2 x 2 the following day.

and so forth

You will have $0.01 x 2^n-1 on day n.

This means that on the 30th day, you have $0.01 x 2^29 = $5 368 709.12.

That is compound interest at work! It equates to daily payments of 100% interest. It immediately soars to inconceivable heights with even a penny as your initial investment!

a jar contains 10 blue marbles and 11 red marbles. two marbles are drawn without replacement. what is the probability of getting two red marbles?

Answers

0.2620 is the probability of getting two red marbles.

What is probability?

Probability is a mathematical discipline that concerns with numerical figures of how probable an occurrence is to occur or how probably a statement is to be true. A number between 0 and 1 is the probability of an occurrence, where, broadly speaking, 0 denotes the event's impossibility and 1 denotes its certainty.

a jar contains 10 blue marbles and 11 red marbles.

So, there total 21 marbles are present.

Now among 21 marbles, 11 are red marble. So, odds of a red on the first are 11/21

Next, there are 20 marbles are present and 10 are red. So odds of a red on the second is 10/20.

For, probability both are red, just multiply

= (11/21) x (10/20)

= 0.2620.

Step-by-step explanation:

a fair coin is flipped nultiple times until it lands on heads if the probability of landing on heads is 50% what is the probability of first landing on heads on the fourth attempt

Answers

If a fair coin is flipped several times until it lands on heads and the likelihood of such outcome is 50%, the probability of the coin landing on heads for the first time is 1/8.

what is probability ?

There are four primary categories of probability: classical, empirical, subjective, and axiomatic. Since possibility and probability are equivalent, you may define probability as the likelihood that a specific event will occur.

given

A fair coin is repeatedly flipped until it comes up heads.

The coin is impartial.

On the third try, we need to calculate the likelihood of the first landing being on heads.

We are aware that each flip of a fair coin is independent of the others, and that each effort results in P(H) = P(T) = 0.5.

Required probability is the likelihood that the third attempt's first landing will be on heads.

= Chance of (I two trials result in tail and third result in head)

=P(I head) P(II head) P(III tail) (since each trial is independent)

= ( 1 /2 ) (1/2)(1/2) = (1/8 )

If a fair coin is flipped several times until it lands on heads and the likelihood of such outcome is 50%, the probability of the coin landing on heads for the first time is 1/8.

Miles is shopping for a new computer. He finds a computer with an original price of $325. 00 but finds that it is 15% off. After paying a 7% sales tax, how much does miles spend on his new computer?.

Answers

Miles has to spend $295.3375 on his new computer.

Sales tax is applied to the price after the discount is applied because discounts are typically provided directly by the retailer and lower both the sales price and the money the retailer receives.

So Original price of Computer  is $325.00

Discount with computer is 15% off.

15% of $325 is (325*15)/100 = $48.75.

Price of computer after discount = 325-48.75 =$276.25

Now sales tax will be applied on this price.

7% sales tax = 0.07

amount of sales tax = 276.25*0.07 = 19.3375

Price of Computer after sales tax   = 276+19.3375 = 295.3375.
