please answer asap

The mean of 1, 2, 3, 4, and 5 is 3, and the standard deviation is 1.58.

To find the mean, you add up all the numbers and divide by the number of numbers you have.

To find the standard deviation, you first find the difference between each number and the mean, square each of these differences, add them up, and divide by the number of numbers you have. Then, you take the square root of this result.

Mean = (1 + 2 + 3 + 4 + 5) / 5 = 15 / 5 = 3

Standard deviation = sqrt(((1 - 3)^2 + (2 - 3)^2 + (3 - 3)^2 + (4 - 3)^2 + (5 - 3)^2) / 5) = sqrt((4 + 1 + 0 + 1 + 4) / 5) = sqrt(10 / 5) = sqrt(2) = 1.58

The term "standard deviation" (or "") refers to a measurement of the data's dispersion from the mean. A low standard deviation implies that the data are grouped around the mean, whereas a large standard deviation shows that the data are more dispersed.

By the distribution property 6(1/2 + 2/3+3/4) = 23/2    

According to the distributive property, multiplying the difference or aum of numbers will be equivalent to multiplying the individual parts of the difference or sum.

The expression that can explain the above rule is A ( B+ C) = AB + AC

Here we have

6(1/2 + 2/3+3/4)    

By distribution property

=> 6(1/2 + 2/3+3/4)  

= 6(1/2) + 6(2/3)+ 6(3/4)  

= 3 + 2(2) + 3(3/2)          

= 3 + 4 + 9/2

= 7 + 9/2

Complete Question:

1. Find the value of this fraction computation: 6(1/2 + 2/3+3/4)    

The price for an 11-mile ride with taxi company is $12

From the question, we have the following parameters that can be used in our computation:

Taxi cab: Company B:

Given that the number of rides is 1, we have the following equation that represents the total price

Total price = 6.50 * 1 ride + 0.50 * Number of miles

So, we have

Total price = 6.50+ 0.50 * Number of miles

For an 11-mile ride with taxi company B, we have

Total price = 6.50+ 0.50 * 11

Evaluate

Total price = 12

Hence, the price is $12

The solution for z in the equation is z = 3y - 1/16(5y + 7x)⁴

From the question, we have the following parameters that can be used in our computation:

2(5y+7x)²=8√(3y-z)

Rewrite the equation

So, we have the following representation

2(5y + 7x)² = 8√(3y - z)

Take the square of both sides

This gives

4(5y + 7x)⁴ = 64(3y - z)

Divide both sides by 64

1/16(5y + 7x)⁴ = 3y - z

So, we have

z = 3y - 1/16(5y + 7x)⁴

Hence, the solution is z = 3y - 1/16(5y + 7x)⁴

Answer:

Step-by-step explanation:

a) Differential equation (initial value problem) for the mass of the copper sulfate would be dm/dt = 0

b) m(t)=0

What is Differential equation?

A differential equation in mathematics is an equation that connects the derivatives of one or more unknown functions. Applications typically use functions to describe physical quantities, derivatives to indicate the rates at which those quantities change, and differential equations to create a relationship between the two.

a) Solution is flowing out of the tank. This can be expressed mathematically as:

dm/dt = (flow rate of solution into tank) - (flow rate of solution out of tank)

= (2 l/min) - (2 l/min)

= 0

Therefore, the differential equation for the mass of the copper sulfate in the tank is:

dm/dt = 0

This is a simple differential equation with a constant coefficient of 0, and it can be easily solved by integrating both sides of the equation with respect to time.

b. To solve the differential equation, we can write:

m(t) = integral(0, t, dm/dt)

= integral(0, t, 0)

= 0

Since the coefficient of the derivative is 0, the solution to the differential equation is a constant function with a value of 0. This means that the mass of the copper sulfate in the tank will remain constant over time, regardless of the flow rates of the solution into and out of the tank.

Yes, because the 16 feet ladder will reach to the window that is 14.5 feet above the ground.

Pythagoras' Theorem states that the square of the hypotenuse side of a right-angled triangle equals the sum of the squares of the other two sides.

The hypotenuse of a triangle, which has a straight angle of 90 degrees, has a square that, according to the Pythagoras theorem, equals the sum of the squares of the other two sides.

According to the question;

A 20-foot ladder is leaning against the side of a house.

Hypotenuse H= 20 feet

The bottom of the ladder is 12 feet from the base of the house.

Base B = 12 feet

And let P be the perpendicular.

Using Pythagoras theorem

H²= P² + B²

20² =12² +P²

P²= 400-144

P²= 256

Taking the square root.

P= 16 feet.

Since the height of the ladder is 16 feet, and we have to reach 14.5 feet above the ground.

16 > 14.5

That means, the ladder will reach to the window.

Hence, Yes, the 16 feet ladder will reach to the window.

Yes, since the midpoint of a line segment is at an equal distance from the two endpoints, it is said to be equidistant from them.

A point is said to be equally far from a group of objects if there is an equal distance between it and each member of the group.

The perpendicular bisector of two specified (different) points is their location in two-dimensional Euclidean geometry. The locus of points equidistant from two provided points in three dimensions is a plane, and generalizing further, the locus of points equidistant from two given locations in n-dimensional space is a (n1)-space.

The circumcenter of a triangle is a location that is equally spaced from each of the three vertices. This point exists in every non-degenerate triangle. The circumcentre of cyclic polygons is equally far from all of the vertices, and this conclusion may be generalized to them.

Answer:

Depends on your school. I took Pre-calculus my 11th grade year. Sometimes it is Algebra 2.

Answer:

3 units.

Step-by-step explanation:

In the equation x = 1/12 (y-1)², the vertex of the parabola is at the point (1,1). The focus of the parabola is located a distance called the "focal length" from the vertex.

The focal length is given by the formula f = 1/(4*p), where p is the coefficient of the x term in the standard form of the equation of the parabola.

In this case, the coefficient of the x term is 1/12, so the focal length is f = 1/(4*(1/12)) = 3. This means that the distance from the focus to the vertex is 3 units.

The volume of the rectangular prism is 3 times the volume of the rectangular pyramid.

Consider a rectangular prism with length l, width w and height h.

The volume of the rectangular prism is:

volume of a rectangular prism = length * width * height

V1 = l * w * h

Consider a rectangular pyramid with rectangular base of length l1, width w1 and the height of pyramid is h1.

The volume of the rectangular pyramid is:

volume of a rectangular pyramid = 1/3 * base area * height

Here, base area = length * width

                          = l1 * w1

So, volume of a rectangular pyramid = 1/3 * base area * height

V2 = 1/3 * l1 * w1 * h1

We have been given a rectangular prism and a rectangular pyramid have equal length, width and height .

l1 = l, w1 = w and h1 = h

so, V2 = 1/3 * l * w * h

V2 = 1/3 * V1

V1 = 3 * V2

volume of a rectangular prism = 3 * volume of a rectangular pyramid

Therefore, the relationship between the volumes of a rectangular prism and a rectangular pyramid whose length width and height are all equal:

By applying the fraction concept, we can conclude that the bunny ate 3/10 food at night.

Application of the concept of fractions in real life

In real life, the concept of a fraction is often used when we want to talk about a part of a whole, a part of something, a part of a group of people, etc.

In the problem above it is stated that initially the bunny has food, which will be eaten in the morning and at night, and some food was left over.

If x is the total food for the bunny, then the given problem can be written mathematically as follows:

breakfast (a) : a = 1/2x

dinner (b)

food left (c) : c = 1/5x

Then the mathematical expression that describes the above situation is as follows:

x = a + b + c

  = 1/2x + b + 1/5x --> then we make the denominators the same, so it becomes:

           x = 5/10x + b + 2/10x

              = 7/10x + b

x - 7/10x = b
