Answer:

x = 3

Step-by-step explanation:

f(x)=4x - 1

f(x)=11, find x.

We want the value of x that would make 4x-1 equal to 11.  Use 11 instead of f(x):

f(x)=4x - 1

11=4x - 1

Solve:

12 = 4x

x = 3

If x were 3, 4x-1 would be 4*3-3 or 11

Answer:

17

Step-by-step explanation:

First, add up the total and find a number divisible for your total which is 105. The next step will be to divide by a number that can go into it easily, like 3 for example. then you would get 35. Since we want the most groups try a number *2 of 3 and that will be 6. After you divide you'll get 17.5 . and since there isn't .5 of a person you go to the lowest number ( not rounding ) and that'll be 17 since 105 divide another multiple of 3 would get you 11.66 repeated.

Step-by-step explanation:

well this is a rather odd equation but I'm assuming that

x+x+x+x+x = 5x

The solution of the given equation [tex]y=6x+20[/tex] is [tex]x = \frac{y + 20}{6}[/tex]

What is linear equation?

An equation is said to be linear if the maximum power of the variable is consistently 1. Another name for it is a one-degree equation.

We have,

                        [tex]y = 6x + 20[/tex]

Arrange the equation both sides so that all variable terms are on the left hand side.

                        [tex]6x - 20 = y[/tex]

Add 20 to both sides of the equation.

                   [tex](6x - 20) + 20 = y + 20[/tex]

                        [tex]6x = y + 20[/tex]

Divide both sides by 6 we get,

                          [tex]\frac{6x}{6} = \frac{y + 20}{6}[/tex]

                      ∴   [tex]x = \frac{y + 20}{6}[/tex]

Hence, final solution is [tex]x = \frac{y + 20}{6}[/tex] .

Using the velocity, the rocket reaches its maximum height at 3.25 seconds.

In the given question we have to find the maximum height at the rocket reaches.

From the question; a toy rocket is shot vertically into the air from a launching pad 5 feet above the ground with an initial velocity of 104 feet per second.

The height h in feet of the rocket above the ground at t seconds after launch is given by the function h(t)= -16t^2+104t+5.

As we know that at the maximum height, the velocity will be zero.

So the given function of the heigth is

h(t)= -16t^2+104t+5

Velocity(v) = dh(t)/dt = -32t+104

As the maximum height v=0

-32t+104 = 0

Subtract 104 on both side, we get

-32t= -104

Divide by -32 on both side

t= 3.25 seconds

Hence, the rocket reaches its maximum height at 3.25 seconds.

The equation of the line passing through (-5, 1) and is parallel to y = -2/5x -5 in standard form is 5y + 2x = -5

The equation of a line can be represented in standard form or slope intercept form as follows;

Slope intercept form,

y = mx + b

where

Line are parallel when they have the same slope.

Therefore, the slope of the equation has a slope of - 2 / 5 x.

The line passes through (-5, 1).

Hence, let's find y-intercept.

y = - 2 / 5 x + b

1 = - 2 / 5 (-5) + b

1  - 2 = b

b = -1

Therefore, y = -2 / 5x - 1.

The equation in standard form should be in the form Ax + By = C.

Hence,

y + 2 / 5 x  = -1

5y + 2x = -5

No the two rectangles are not similar as the ratios of the sides are not equal.

Two rectangles are said to be similar if the ratio of the sides of the rectangles are equal.

Now let us consider the given rectangles:

In rectangle ABCD:

AB = 18

AD = 36

In rectangle WXYZ :

WX = 25

XY = 45

Now the ratio of the sides of the rectangle are:

AB/AD = 18 / 36 = 1 / 2

WX/XY = 25 / 45 = 5 / 9

Thus we can see that AB : AD ≠ WX : XY

Hence the rectangles are not similar.

If the ratios of the adjacent sides of two rectangles are equal, then they are similar. A rectangle is a quadrilateral in the Euclidean plane because it has four right angles.

Other definitions include a parallelogram with a right angle or a quadrilateral that is equiangular, where equiangular denotes that all of its angles are equal. A square is a rectangle with four equally long sides.

The equation that represents the proportional relationship is y = 14x.

We are given a table. The table contains the values for "x" and "y". The first row contains the data for the variable "x". The values of "x" are 1, 2, and 3. The second row contains the data for the variable "y". The corresponding values of "y" are 14, 28, and 42. We know that the table shows a proportional relationship between the values of "x" and "y". Let the constant of proportionality be represented by the variable "k".

y ∝ x

y = k*x

k = y/x

The value of k must be the same for each corresponding pair of values of "x" and "y".

k = 14/1 = 28/2 = 42/3 = 14

Hence, the equation is y = 14x.

The F-test is used in regression analysis to test the hypothesis that all model parameters are zero. It is also used in statistical analysis when comparing statistical models.

Statistical models that have been fitted using the same underlying factors and data set to determine the model with the best fit. That is:

H₀ : B₁ = B₂ = .............  = Bₓ =0

H₁: Bₙ ≠ 0 for at least one j.

The F-test was developed by Ronald A. Fisher (hence F-test) and is a measure of the ratio of variances. The F-statistic is defined as:

F = [tex]\frac{explained variables}{unexplained variables}[/tex]

A general rule of thumb that is often used in regression analysis is that if  

F > 2.5then we can reject the null hypothesis. We would conclude that there is a least one parameter value that is nonzero.

The F-distribution is generally a skewed distribution and also related to a chi-squared distribution. The f distribution is the ratio of X1 random chi-square variable with degrees of freedom ϑ1 and X2 random chi-square variable with degrees of freedom ϑ2. (In other words each of the chi-square random variable has been divided by its degrees of freedom)

2B times as many gallons does pool A hold than pool B.

What is gallons?

The gallon is a volumetric unit that is used in both imperial and American customary measurements.

The imperial gallon (imp gal), which is equal to 4.54609 liters and was once used in various Caribbean nations as well as the United Kingdom, Ireland, Canada, Australia, and Australia.

Given:

Swimming pool A has 2^15 gallons of water.

Swimming pool B has 2^13 gallons of water.

We have to find the number of times pool A hold than pool B.

It is obvious that Swimming Pool A holds more water than Swimming Pool B.

Consequently, we must determine how many times as many gallons Pool A holds as Pool B:

2^15 > 2^13.

Therefore,

A = 2^15,  B = 2^15

[tex]A = (\frac{2^1^5}{2^1^3}) B = 2B\\ A = 2B[/tex]
