Assuming [x] means the closest integer to x

Answer:

\((-\infty, \infty)\)

Step-by-step explanation:

We can see that for any integer \(x\), there will always be a \([x]\), so there will always be a \([x]+1\). So, we don't need to worry about the domain impacting the range.

\([x]\) can be any integer from \(-\infty\) to \(\infty\), and as \(\infty+1=\infty\)(at least in terms of a function's range and domain), the range of \([x]+1\) is equal to the range of \([x]\), which is \((-\infty, \infty)\).

So, the answer is \(\boxed{(-\infty, \infty)}\) and we're done!

The measure of angle FBE in the figure is 40 degrees

The triangles represent the given parameter

This means that we make use of the triangles (the big and the small triangles) in our computation

Also, from the question, we have the following known parameters

CD = DA

AE = EB

FDE = 40 degrees

The congruent side equations CD = DA and AE = EB imply that the following side lengths are congruent

So, we have the following equations

DE = FB

DF = EB

This also means that DFBE is a parallelogram

The opposite angles of a parallelogram are congruent

So, we have

angle FBE = angle FDE

Substitute the known values in the above equation, so, we have the following representation

angle FBE = 40 degrees

Hence, the angle is 40 degrees

The value of length BC is 18.9

Cosine Rule states that the square of the length of any side of a given triangle is equal to the sum of the squares of the length of the other sides minus twice the product of the other two sides multiplied by the cosine of angle included between them.

Therefore,

c² = a² + b² - 2abcosC

To find the length BC we use cosine rule.

c² = 13² + 7² - 2(13)(7)cos140

c² = 218 - 182cos140

c² = 218-(-139.42)

c² = 218+139.2

c² = 357.2

c = √357.2

c = 18.9

Answer:

Step-by-step explanation:

In 10 seconds his wings will flap 800 times!

So in 60 seconds his wings will go 6 times more frequently.

10 /800 = 60/x

10 x = 800 * 60

10 x = 48000

x = 48000/10

x = 4800

The possible price for the items if the store sells $600 is (c) $40

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

The supply-demand graph

If the store sells $600, then there is a supply worth of $600

The equation of the supply line is calculated as

y = mx + c

Where

c = y = 0

i.e. c = 100

So, we have

y = mx + 100

Using another point on the graph, we have

30m + 10 = 400

So, we have

m = 13

This means that

y = 13x + 100

For a supply of 600, we have

13x + 100 = 600

So, we have

13x = 500

Divide by 13

x = 38.4

Approximate

x = 40

Hence, the possible price for the items is (c) $40

None of the options are valid because the specified functions are both parabolic.

Functions represent the connection between two groups of values. For instance, if y=f(x), each value of x has a corresponding value in the set of y. The dependent variable is Y, and the independent variable is x.

An example of a rule is a function, which produces one output for a single input. Alex Federspiel is the picture's author. Y=X2 is an illustration of this. You only get one output for y if you enter anything for x. The fact that x is the input value leads us to say that y is a function of x. In mathematics and the sciences, functions are fundamental for constructing physical relationships.

Given functions in this case are

There is no possible way for a base of a triangle to be 27 times bigger than one of the equal legs.      It's like asking a T-Rex for a round of applause...not gonna happen.

Even a ratio of 2.7 is not going to work. 0.27 might work, though. Let's assume the ratio is 0.27

x + x + 0.27x = 304

2.27x = 304

x = 133.92070...

The best-predicted height for someone with a foot length of 20.4 cm is approximately 65.83 cm.

To find the best-predicted height for someone with a foot length of 20.4 cm, we need to use the linear regression equation that relates foot length and height. The linear regression equation is of the form:

y = a + bx

where y is the predicted height, x is the foot length, a is the y-intercept, and b is the slope of the regression line.

From the given information, we know that the technology found a linear correlation between height and foot length. This means that we can use the paired data to calculate the values of a and b in the regression equation.

Using the paired data and technology, we can obtain the following regression equation:

height = 34.774 + 1.4966 (foot length)

Now we can substitute the given foot length of 20.4 cm into the equation to obtain the predicted height:

height = 34.774 + 1.4966 (20.4)

height = 65.83 cm

Therefore, the best-predicted height for someone with a foot length of 20.4 cm is approximately 65.83 cm.

What is standard deviation ?

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.

Think about the following data: 2, 1, 3, 2, 4. The average and the total square of the observations' departures from the mean will be 2.4 and 5.2, respectively. This means that (5.2/5) = 1.01 will be the standard deviation.

The following null and alternative hypotheses need to be tested

H0 :  µ  = 16

Hα :  µ  < 16

This corresponds to a left-tailed test , for which a z-test for one mean, with known population standard deviation will be used.

Based on the information provided, the significance level is α = 0.1, and the critical value for the left-tailed test is \(Z_{c}\) = -1.28

The rejection region for this left-tailed test is R = {z : z < -1.282}

The z-statistics is computed as follow

\(z = \frac{X - µ _{0} }{sigma / \sqrt{n} }\)

   = (15.84 - 16) / (0.4 / √16)

Answer:

If solving an equation yields a statement that is true for a single value for the variable, like x = 3, then the equation has one solution. If solving an equation yields a statement that is always true, like 3 = 3, then the equation has infinitely many solutions.

Step-by-step explanation:

In these equations, any value for the variable makes the equation true. You can tell that an equation has infinitely many solutions if you try to solve the equation and get a variable or a number equal to itself.

Points A = (-5, 1)        →     Points A' = (-(-5), -(1)) = (5, -1).

37.5w + 155.95 = 455.95; where w = 8; signifies the number of weeks required to babysit the business in order to purchase the gaming chair.

A mathematical formula that connects two expressions with the equals sign (=) expresses the equality of the two expressions. For instance, in English, an equation is any properly stated formula that consists of two expressions linked by the equals sign, whereas in French, an equation is described as containing one or more variables. To solve a variable equation, identify the values of the variables that cause the equality to hold true. The answer is known as the values of the variables that must satisfy the equality.

Equations can be categorized as identities or conditional equations.

w = (455.95-155.95)/(37.50)

=300/37.50

So, number of weeks = 8

As a result, w = 8 and 37.5w + 155.95 = 455.95 is the solution.
