The weight of the object on Mars would be 40 pounds.

What are ratio and proportion?

A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other.

An object that weighs 50 pounds on mars weighs 150 pounds on earth.

Let the object weighing 120 pounds on Earth, weighs x pounds on Mars.

We can solve this equation as :

                50/150 = x/120

                 x = 40 pounds

Hence, the weight of the object on Mars would be 40 pounds.

The given statement "the value in the middle of a confidence interval is always the point estimate for the population parameter" is TRUE.

In statistics, a confidence interval describes the likelihood that a population parameter would fall between a set of values for a given percentage of the time.

Confidence ranges that include 95% or 99% of anticipated observations are frequently used by analysts.

The point estimate for the population parameter is always the value at the center of a confidence range.

You have a 5% probability of being incorrect with a 95% confidence interval.

We have a 10% probability of being incorrect with a 90% confidence interval.

A 95% confidence interval is narrower than a 99% confidence interval (for example, plus or minus 4.5 percent instead of 3.5 percent).

Therefore, the given statement "the value in the middle of a confidence interval is always the point estimate for the population parameter" is TRUE.

The set of rational numbers is closed under addition, subtraction, multiplication, and division (division by zero is not defined) because if you complete any of these operations on rational numbers, the solution is always a rational number. -1 and 1.

What is a closed set ?

A Closed Set Math has a way of explaining a lot of things, and one of those explanations is called a closed set.

Closure property holds for addition and multiplication of whole numbers. The sum of any two whole numbers will always be a whole number, i.e. if a and b are any two whole numbers, a + b will be a whole number. The difference between any two whole numbers may or may not be a whole number. Hence, the whole numbers are not closed under subtraction.

According to the given question:

A set is closed under addition if you can add any two numbers in the set and still have a number in the set as a result. A set is closed under (scalar) multiplication if you can multiply any two elements, and the result is still a number in the set.

The term Ratio in math basically compares quantities, which means that it shows the value of one quantity with respect to the other quantity.

Here we have given that the florist ordered a shipment of red, blue, and white carnations to use for table decorations at a banquet.

And we need to find  the total number of carnations in the shipment.

While we looking into the given question, we know that the ratio of red : blue : white carnations in the shipment is 3:1:2.

Here we aloo know that there are 60 white carnations in the shipment

Then let us consider if a and b are two values, their ratio will be a:b,

Then the ratio of flowers is written as

=> red: blue: white = 3:1:2

Where red flowers are 3x, and the blue flowers are x, and the white flower are 2x.

So, the total number of flowers = 3x+x+2x = 6x

When we apply the value of whit\te flowers = 60

Then the value of x is calculated as,

=> 2x = 60

=> x = 30

Hₐ = Average family size is not 3.18

The value of t = (Sample Mean - 3.18) / s/√n

where,

Sample Mean = 3.83

n = 24

s = 1.43

So, t = (3.83 - 3.18) / (1.43 / √24)

Answer:

Step-by-step explanation:

Part A: you can just restate parts of the text to make a vaild argument or you can make you own

Part B: he should measure N, O, P and Qas

Triangles MNO and QPO are congruent. To find the width of the creek, Andre should find the measurement of NP

When two triangles are congruent, their corresponding three sides and their three angles match precisely.

Given that

O is the midpoint of NP,

NP is perpendicular to MN, and

NP is perpendicular to PQ.

When two lines intersect at a specific point, the opposite angles formed in this situation are equal.

a) Then ∠MNP =∠QPO=90°

∠MON=∠QOP

Also, NO = OP (by the definition of midpoints)

Therefore, Triangles MNO and QPO are congruent by ASA rule

And,

A multiplicative comparison involves comparing two quantities such that when one is multiplied by a specified number, the other is produced. For example, Sam has twice as many balloons as Sid. Sid has 3 balloons.

For a second order differential equation t²y'' - 4ty' + 6y = 0, general solution is of the form y(t) = c₁t² + c₂t³, so another solution other than y₁(t) = t² is y₂(t) = t³.

Given solution to t²y'' - 4ty' + 6y = 0 is

y₁(t) = t²

Using the method of reduction of order, let us assume, y₂(t) = v(t)y₁(t) is a solution to t²y'' - 4ty' + 6y = 0 for suitable choice of v(t). So,

y₂ = vt²

y₂' = 2vt + t²v'

y₂'' = 2v + 2tv' + 2tv' + t²v''

y₂'' = 2v + 4tv' + t²v''

Substituting this

t²×( 2v + 4tv' + t²v'') - 4t×(2vt + t²v') + 6×(vt²) = 0

t⁴v'' = 0

v'' = 0

v' = c, c is a constant

v = ct

Therefore, y₂(t) = ct×t²

y₂ (t) = ct³

Therefore general solution will be y(t) = c₁t² + c₂t³

Step-by-step explanation:

Solve for x:

Subtract 36 from both sides:

25 x^2 = -36

Divide both sides by 25:

x^2 = -36/25

Take the square root of both sides:

Answer:  x = (6 i)/5 or x = -(6 i)/5

The equation in slope-intercept form of the line that crossed the x-axis at 36 and is perpendicular to the line represented by y = -4/9x + 5​ is y = 9/4 ( x ) + 36

Given :

line equation is y = -4/9 x + 5

We have to find the line equation which is perpendicular to the given line in slope intercept form.

y = mx + c where m is slope and c is intercept.

slope m = -4/9

perpendicular slope = -1/m

Answer:

  5 units

Step-by-step explanation:

You want to know the side length of the rhombus with vertices (2, 0), (7, 0), (5, 4), and (10, 4).

You can find the length of the horizontal edges by counting the grid squares, or by subtracting the x-coordinates:

  7 -2 = 5

  10 -5 = 5

The slanted sides are each the hypotenuse of a 3-4-5 right triangle, so are also 5 units long. (You expect all of the sides of the rhombus to be the same length.)

Each side is 5 units long.

The answer is 5, 4.47, 5, and 8.94.

                The distance formula is d = √(x2-x1)^2 + (y2-y1)^2

                                    d = √(7-2)^2 + (0-0)^2

                                    d = √(5)^2 + (0)^2                

                                    d = √(25) + (0)

                                    d = 5

                                     d = √(5 - 7)^2 + (4 - 0)^2

                                      d = √(-2)^2 + (4)^2

                                      d = √4 + 16

                                      d = √20

                                      d = 4.47

                                      d = √(10 - 5)^2 + (4 - 4)^2      

                                      d = √25 + 0

                                      d = 5

                                       d = √(2 - 10)^2 + (0- 4)^2

                                       d = √(-8)^2 + (-4)^2

                                       d = √64 + 16

                                       d = √80

                                       d = 8.94

Therefore, each side of the rhombus has a length of 5, 4.47, 5, and 8.94.
