A 60kg Student In A Rowboat On A Still Lake Decides To Dive Off The Front Of The Boat. The Student's

Answers

Answer 1

The horizontal force that the student exert on the boat is 120 N toward the front of the boat.

What is third law of Newton ?

As per the third law of Newton, the force exerted by the boat over the student is equal in magnitude to the force that the student exerted on the boat.

So, calculate the force on the student using the second law of Newton, Force = mass * acceleration.

Force on the student = 60 kg * 2.0 m/s^2 = 120 N.

=> horizontal force exerted by the student on the boat = 120 N

Answer: option d. 120 N. toward the back of the boat.

Of course it is toward the back because that is where the student jumped from..

To host a party at a local restaurant ,you must pay $____to rent it and $___ per guest.

Answers

The equation is y = 15x + 90. The initial value is 90. Rate of change is: 15.

To host a party at a local restaurant, you must pay $90 to rent it and $15 per guest.

How to Write a Linear Equation?

To write a linear equation that models a situation in slope-intercept form, y = mx + b, find the following:

Initial value/y-intercept (b), which is the value of y when x = 0.Rate of change / slope (m), which is the ratio of change in y / change in x.

Given the table above, the value of y when x = 0 is 90. This means the initial value (b) = 90.

Using two pairs of values from the table, (0, 90) and (6, 180):

Rate of change (m) = (180 - 90) / (6 - 0) = 15

Substitute m = 15 and b = 90 into y = mx + b, to write the equation:

y = 15x + 90.

Answers

The hypothesis, at the 0.05 significance level,

H₀ : the observed distribution of X may be fitted by the geometric distribution

Hₐ : the observed distribution of X may not be fitted by the geometric distribution

we conclude p-Value > α so, cannot reject null hypothesis. The observed distribution of X may be fitted by the geometric distribution g(x ; 1 / 2), x=1,2,3

A coin is thrown until a head occurs and the number X of tosses recorded.

The probability that head occur on toss ,p = 0.5

Consider the null and alternative hypothesis,

H₀ : the observed distribution of X may be fitted by the geometric distribution

Hₐ : the observed distribution of X may not be fitted by the geometric distribution

The chi square test statistic here as:

χ² = ∑( Oᵢ - Eᵢ)²/Eᵢ

where Oᵢ--> observed value

Eᵢ --> expected value

and the expected frequencies for each X here E(x) = P(X = x) = 256×g(x)

The probability mass function of geometric distribution with parameter 1/2 is g(x) = (1/2)(1 - 1/2)⁽ˣ⁻¹⁾

where x = 0, 1,2 ,3,......

Observed values are f :136 60 34 12 9 1 3 1

Using the data,we calculate the expected values

E₁ = P( x = 1) = 256×g(1) = 256×(1/2)(1/2)⁰

= 128

E₂ = P( x =2) = 256×g(2) = 256×(1/2)(1/2)¹

= 64

E₃ = P( x = 3) = 256×g(3) = 256×(1/2)(1/2)² = 32

E₄ = P( x = 4) = 256×g(4) = 256×(1/2)(1/2)³

= 16

E₅ = P( x = 5) = 256×g(5) = 256×(1/2)(1/2)⁴

= 8

E₆ = P( x = 6) = 256×g(6) = 256×(1/2)(1/2)⁵

= 4

E₇ = P( x = 7) = 256×g(7) = 256×(1/2)(1/2)⁶

= 2

E₈ = P( x = 8) = 256×g(8) = 256×(1/2)(1/2)⁷

= 1

Hence, χ² = ∑( Oᵢ - Eᵢ)²/Eᵢ

= (136 - 128)²/128 + (60 - 64)²/64 + (34 - 32)²/32 + (12-16)²/16 +(9 - 8)²/8 + (1 - 4 )²/4 + (3 - 2)²/2 +(1 - 1)²/1

= 0.5 + 0.25 + 0.125 + 1 + 0.125 + 2.25 + 0.5 =4.75

Significance level is α =0.05

Using the χ² table, the p- value for χ² is 0.6290 .. Now P value > 0.05 , therefore the test is not significant here and we cannot reject the null hypothesis here. Therefore we have sufficient evidence here that the frequencies given are fitted by the geometric (p = 0.5) distribution.

Answer:

x = 9

Step-by-step explanation:

Use Vertical Angles and Supplementary Angles to put all the given information inside the triangle.

Then use the idea that the three angles in a triangle add up to 180° to write an equation.

see image.

Actually also--shortcut! The 150° is an exterior angle, so it is equal to the

90° + 5x+15

90 + 5x + 15 = 150

this calculation comes out the same as the other.

Answer:

  x = 9

Step-by-step explanation:

Given a right triangle with an exterior angle of 150°, and a vertical angle to the other acute angle marked as 5x+15, you want to solve for x.

Exterior angle

The exterior angle is equal to the sum of the remote interior angles. One of those is the right angle; the other is a vertical angle with respect to the one marked 5x+15. So, we have ...

  150 = 90 + (5x +15)

  45 = 5x . . . . . subtract 105

  9 = x . . . . . . divide by 5

What is Poisson probability distribution ?

The Poisson distribution is a theoretical discrete probability, also known as the Poisson distribution probability mass function. It is used to find the probability that independent events occur at regular time intervals and have a constant average rate. λ is the Poisson rate parameter, the expected average number of events over a given time interval.

Using the Poisson distribution formula:

P(X = x) = (e-λ (λˣ) )/x!

where λ is mean number or poisson rate parameter ; x = 0, 1, 2, 3...

e is the Euler's number(e = 2.718)

We have given that,

Total number of Manuscript Pages = 400

total misprinted pages = 200

let X be random variable that the page is misprinted .

Mean number, λ = 200/400 = 0.5

the probability that it has 3 misprints, P(X= 3) = (e⁻⁰·⁵ (0.5)³ )/3!

= e⁻⁰·⁵ ( 0.125 )/6 =0.075816/6 = 0.0126

Answers

Answer:

x = 6

Explanation:

If x is reserved for the number of hours it'll take, then the first equation is saying that $6 is being multiplied by an x amount of hours, which is then added by $30. The second equation states that $11 is being multiplied by an x amount of hours, but there is no flat fee. This makes the equation:

6x + 30 = 11x

The steps to solving this are:

1) Make the variables on one side. In this case, it is easier to put them on the right.

11x - 6x = 5x

5x = 30

2) Divide both sides by 5.

5x / 5 = 30 / 5

x = 6

This means it will take 6 hours for them to charge the same amount of money.

The perimeter of the rectangle 24x + 1 feet. The perimeter of a geometric figure is the total length of its sides.

What is perimeter ?

A closed path that covers, encircles, or outlines a one-dimensional length or a two-dimensional shape is called a perimeter. A circle's or an ellipse's circumference is referred to as its perimeter. There are numerous uses in real life for perimeter calculations.

To find the perimeter of a rectangle, you need to add the lengths of all four sides of the rectangle.

The width of the rectangle is 4x-7.5 feet and the length is 7.5x+8 feet.

The perimeter is therefore equal to 2 times the sum of the width and the length,

= 2 * (4x-7.5 + 7.5x + 8) feet.

This simplifies to 2 * (12x + 0.5) feet,

which is equal to 24x + 1 feet.

Given: ray AC is parallel to ray DE, measure angle FED= measure angle GCA= 45°
Prove: ray FE is parallel to ray GC

Answers

We have proved that the ray FE is parallel to the ray GC.

What is meant by parallel lines?

In geometry, parallel lines are coplanar straight lines that do not intersect at any point. Parallel planes are planes in the same three-dimensional space that never meet. Parallel curves are curves that do not touch each other or intersect and keep a fixed minimum distance.

Angle DEF intersects at B

which results in angle DEF corresponding to the angle  ACG.

As DEF = 45 so angle ACG = 45

So by the above discussion, we can say that the ray FE is parallel to the ray GC.

Hence, we have proved that the ray FE is parallel to the ray GC.

Step-by-step explanation:

I apologise for my messy explanation.

The solution of the expression will be;

⇒ x = 5.7

or ⇒ x = 0.07

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ log ₂ (3x + 2) - log ₄ (x) = 3

Now,

Since, The expression is,

⇒ log ₂ (3x + 2) - log ₄ (x) = 3

Solve as;

⇒ log ₂ (3x + 2) - 1/2 log ₂ (x) = 3

⇒ log ₂ (3x + 2) - log ₂ √(x) = 3

⇒ log ₂ (3x + 2) / (√x) = 3

⇒ (3x + 2) / √x = 2³

⇒ (3x + 2) / √x = 8

⇒ (3x + 2) = 8√x

Taking square both side, we get;

⇒ (3x + 2)² = (8√x)²

⇒ 9x² + 12x + 4 = 64x

⇒ 9x² + 12x - 64x + 4 = 0

⇒ 9x² - 52x + 4 = 0

By applying quadratic formula, we get;

⇒ x = - (- 52) ± √ (-52)² - 4×9×4 / 2×9

⇒ x = 52 ± √ 2704 - 144 / 18

⇒ x = 52 ± √2560 / 18

⇒ x = 52 ± 50.6 / 18

This gives two solution as;

⇒ x = (52 + 50.6) / 18

⇒ x = 102.6/18

⇒ x = 5.7

And, We get;

⇒ x = 52 - 50.6 / 18

⇒ x = 1.4 / 18

⇒ x = 0.07

The values of the angles x, y, z are x=56°, y=124°, z=56°

What is meant by an angle?

In Euclidean geometry, an angle is a figure made up of two rays that have a shared vertex, also known as a common terminus, and are referred to as the angle's sides. The angles of two rays are situated in the plane containing the rays. An angle is also created when two planes intersect at an angle. These are referred to as dihedral angles. Another technique to define two curves is to specify the angle generated by rays that are tangent to the intersection of two curves. Angle is another word for how long a rotation or angle is.

From the given figure,

∠y=124°

∠x+124°=180°

∠x=180°-124°

∠x=56°

∠x=∠z=56°

Therefore, The values of the angles x, y, z are x=56°, y=124°, z=56°
