Based on these values, the interval  that likely to contains the true mean number of pizzas eaten in the previous year by the population is :5.1-7.7

What does a margin of error mean?

The margin of error of 1.3 means that the interval that contains the true mean of the people sampled is the mean plus or minus the margin of error, in other words, the mean of 6.4 could either be greater by 1.3 or less by 1.3

interval containing the true mean number=mean± marginal of error

upper limit of the mean interval=6.4+1.3

The  swimmer will swim 15.23 cm.

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

The formula for the Pythagoras theorem is written as c² = a² + b², where c is the hypotenuse of the right triangle and a and b are its other two legs. As a result, the Pythagoras equation can be used to any triangle that has one angle that is exactly 90 degrees to create a Pythagoras triangle.

Given:

Perpendicular = 14 m

Base = 6 m

Using Pythagoras theorem

H²= P² + B²

H² = 14² + 6²

H² = 196 +36

H² = 232

H= 15.23 cm

Hence, the swimmer will swim 15.23 cm.

The exponential form of the function 5 = log₂ₓ₊₁(a₊b) is (2x ₊ 1)⁵ = (a₊b).

Given the function is:5 =  log₂ₓ₊₁ (a₊b)

we are asked to determine the exponential form of the above function.

The exponential form is an easier way to represent repeated multiplication involving exponents and bases.

It is easy to quickly convert an exponentially written expression into a logarithm using the following formula.

here we have the form loge b  =a5 =  log₂ₓ₊₁(a₊b)

then, e = 2 , a = 5 and

b = (a₊b)5 =  log₂ₓ₊₁(a₊b)

therefore, exponential form is:

(2x ₊ 1)⁵ = (a₊b).

hence we get the required exponential form as (2x ₊ 1)⁵ = (a₊b).

Answer:

The elevator is two floors below the ground level. The integer to represent this is -2.

Step-by-step explanation:

We get the equation in logarithmic form as log₈ 64 = 2

A “logarithmic equation” is an equation which involves the “logarithm” of any expression which is containing a variable.

Now, we have been given an equation:

8² = 64

We need to write it in the logarithm form.

We know that, it will be written as:

log₈ 64 = 2

Since the power goes after the equal sign, so 2 is placed after the equal sign.

The actual value is taken after log, so 64 is placed there and the base number is taken as the base for the log, so 8 is taken as the base for the log.

Therefore, we get the equation in logarithmic form as log₈ 64 = 2

Solve a System of Linear Equations by Graphing

In this chapter we will use three methods to solve a system of linear equations. The first method we’ll use is graphing. The graph of a linear equation is a line. Each point on the line is a solution to the equation. For a system of two equations, we will graph two lines. Then we can see all the points that are solutions to each equation. And, by finding what the lines have in common, we’ll find the solution to the system.

Most linear equations in one variable have one solution, but we saw that some equations, called contradictions, have no solutions and for other equations, called identities, all numbers are solutions. Similarly, when we solve a system of two linear equations represented by a graph of two lines in the same plane, there are three possible cases, as shown in Figure  5.1.1 :

This figure shows three x y-coordinate planes. The first plane shows two lines which intersect at one point. Under the graph it says, “The lines intersect. Intersecting lines have one point in common. There is one solution to this system.” The second x y-coordinate plane shows two parallel lines. Under the graph it says, “The lines are parallel. Parallel lines have no points in common. There is no solution to this system.” The third x y-coordinate plane shows one line. Under the graph it says, “Both equations give the same line. Because we have just one line, there are infinitely many solutions.”

Figure  5.1.1

For the first example of solving a system of linear equations in this section and in the next two sections, we will solve the same system of two linear equations. But we’ll use a different method in each section. After seeing the third method, you’ll decide which method was the most convenient way to solve this system.

The steps to use to solve a system of linear equations by graphing are shown below.

TO SOLVE A SYSTEM OF LINEAR EQUATIONS BY GRAPHING.

Graph the first equation.

Graph the second equation on the same rectangular coordinate system.

Determine whether the lines intersect, are parallel, or are the same line.

Identify the solution to the system.

If the lines intersect, identify the point of intersection. Check to make sure it is a solution to both equations. This is the solution to the system.

If the lines are parallel, the system has no solution.

If the lines are the same, the system has an infinite number of solutions.

Exercise  5.1.12

Answer

Usually when equations are given in standard form, the most convenient way to graph them is by using the intercepts. We’ll do this in Exercise  5.1.13 .

Exercise  5.1.13

Sopt form.y=12x−3m=12,b=−3{y=12x−3x−2y=4 If we solve the second equation for y, we get x−2y=4x−2y=−x+4y=12x−2m=12,b=−2

The two lines have the same slope but different y-intercepts. They are parallel lines.

Figure  5.1.3  shows how to determine the number of solutions of a linear system by looking at the slopes and intercepts.

Two angles have sum as 180° called supplementary angle so the measure of angle C m∠C will be 68.68°.

An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.

The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.

Given that,

Angle A and angle B are supplementary

Since the supplementary angle has a sum of 180 degrees.

So,

m∠A + m∠B = 180°

16x - 7 + 21x + 2 = 180

16x + 21x + 7 - 2 = 180

37x + 5 = 180

37x = 175

x = 4.78

So,

m∠A = 16(4.78) - 7 = 68.68°

Since m∠C = m∠A

So,

m∠C = 68.68°

Hence"The measure of angle C m∠C will be 68.68° ".

Answer:

Step-by-step explanation:

To round to one decimal place you have to round the number to its "tenths". When you are rounding, any number which is 5 or above is rounded to the tenth above or in this situation 6 making it 12.5. But any number below 5 is going to be rounded to the tenth below so if the number was 12.44172 then the answer would 12.4. GL and mb if i messed up.

The function definition is an arithmetic sequence and the value of the function f(6) is -12

The function definition is given as

f(1) = 8

f(n) = f(n + 1) + 4

Rewrite the above function as

f(n + 1) = f(n) - 4

Set n = 1

So, we have

f(1 + 1) = f(1) - 4

This gives

f(2) = f(1) - 4

So, we have

f(2) = 8 - 4

Evaluate

f(2) = 4

Set n = 2

So, we have

f(2 + 1) = f(2) - 4

This gives

f(3) = f(2) - 4

So, we have

f(3) = 4 - 4

Evaluate

f(3) = 0

Set n = 3

So, we have

f(3 + 1) = f(3) - 4

This gives

f(4) = f(3) - 4

So, we have

f(4) = 0 - 4

Evaluate

f(4) = -4

Set n = 4

So, we have

f(4 + 1) = f(4) - 4

This gives

f(5) = f(4) - 4

So, we have

f(5) = -4 - 4

Evaluate

f(5) = -8

Set n = 5

So, we have

f(5 + 1) = f(5) - 4

This gives

f(6) = f(5) - 4

So, we have

f(6) = -8 - 4

Evaluate

f(6) = -12

Hence, the value of the function f(6) is -12
