Quadratic

Step-by-step explanation:

The equation of the regression line model for the data plot determines a quadratic equation

The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.

In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.

A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.

Given data ,

Let the linear regression line be represented as A

Now , the value of A is

Let the first coordinate on the graph be P ( 1 , 5.5 )

Let the second coordinate on the graph be Q ( 2 , 6 )

And , the data plots on the graph represents a curve or parabolic equation

So , it is a quadratic equation

Hence , the data plot of the regression line is quadratic

#SPJ7

Answer:

22%

Step-by-step explanation:

Given that:

Number of hours at work daily = 8 hours

Number of days at work per year = 240

Total number of hours at work per year = Number of hours at work daily [tex]\times[/tex] Number of days at work per year

Total number of hours at work per year = 8 [tex]\times[/tex] 240 = 1920 hours

Total number of days in an year = 365

Total number of hours per day = 24

Total number of hours in an year = 24 [tex]\times[/tex] 365 = 8760

Here, to find the probability that the earthquake will occur while the person is at work, we actually have to find the fraction of number of hours at work to the total number of hours in an year.

Therefore, the required probability is:

[tex]\dfrac{1920}{8760} \approx \bold{0.2191}[/tex]

Therefore the probability to the nearest percent is: 22%

Answer:

C) 640%

Step-by-step explanation:

6 2/5

Convert it to an improper fraction -

6 2/5 = 32/5

Convert the improper fraction to a decimal -

32/5 = 6.4

Multiply 6.4 by 100

= 640%

Hope this helps :)

Answer: Oooohhhh, I knew the answer the answer is 640%.

Step-by-step explanation: So start by separating the parts: [tex]6+\frac{2}{5}[/tex],

Then I know that [tex]\frac{2}{5} = 2/5[/tex],

∴ [tex]6\frac{2}{5} = 6+(2/5)[/tex],

Then I use The Long Division for 2 divided by 5, so I have [tex]6+0.4=6.4[/tex],

And last but not least is onverting our number to a percentage: [tex]6.4*10=640%[/tex] (Rounded to a Max of 2 Decimal Places.), so I hope this formula could be helpful, but if you have struggle to convert the mixed number fraction to percentage, please ask me, okay? :)

Answer:

21 minutes

Step-by-step explanation:

Given that:

7 identical taps fill 3 identical tanks in 45 minutes

Since the taps and tanks are identical :

Hence, the 7 taps can fill 1 tank in :

45 /3 = 15 minutes

Therefore, 1 tap will fill 1 tank in :

7 tap = 15 minutes

1 tap = (15 * 7) = 105 minutes

Hence, 5 taps will fill 1 tank in :

105 minutes / 5

= 21 minutes

We are given:

Sin(6θ)  = Cos(3θ)

Solving for θ:

Simplifying Cos(3θ):

We know that:  

Cos(θ) = Sin(90-θ)

So, we can say that:

Cos(3θ) = Sin(90 - 3θ)

Finding the value of θ:

Sin(6θ) = Cos(3θ)

Sin(6θ) = Sin(90 - 3θ)                             [Since Cos(3θ) = Sin(90 - 3θ)]

6θ = 90 - 3θ                                            [If Sin(θ) = Sin(A) ; θ = A]

9θ = 90                                                   [adding 3θ on both sides]

θ = 10°                                                     [dividing both sides by 9]

Answer:

sin(5x)

Step-by-step explanation:

Recall that the half angle identity relates the sine of half an angle to the square root of one minus the cosine of the angle as shown below:

[tex]sin(\frac{\theta}{2} )=+/-\sqrt{\frac{1-cos(\theta)}{2} }[/tex]

therefore, in our case:

[tex]sin(5\,x )=+/-\sqrt{\frac{1-cos(10\,x)}{2} }[/tex]

so, make sure you type the expression : "sin(5x)" in the provided text-box.

i have this question and this what i got its right

Answer:

1. The speed of the truck, S = D/T.

2. The formula that connects D and T is: S = D/T.

3. The coefficient of variation, k, is the ratio of the standard deviation to the mean speed.

Step-by-step explanation:

a) The speed of a truck at a fixed speed is given as the distance covered by the truck divided by the time it takes the truck to cover the said distance.  This implies that speed is a function of distance and time.  However, this formula represents the mean speed.  There are variations in speed.

b) If the truck covers a distance of 60 kilometers, for example, under 3 hours, we can conclude that the speed is 20 kilometers per hour (60/3) or 20 km/hr.

Answer:

Terminating

Step-by-step explanation:

Since the number ends exactly after 3 decimal places, it is a terminating decimal number.

On the other hand, repeating decimal numbers are numbers such as 2.33... or 8.66... that repeat the number forever.

So, the number 1.255 is terminating.

Answer: The axis of symmetry   = 1  

That's  a vertical line passing through 1 on the x-axis

Step-by-step explanation:  From standard form, ax² + bx + c

Use the values of a and b in the equation  x = -b/2a to find s, the axis of symmetry.

x = -(-6)/2(3)  

x = 6/6

x = 1

The required axis of the symmetry of the given parabola is x = 1.

Given that,
To determine the axis of symmetry of y = 3x² - 6x + 4.

A parabola is a cross-section cut out of the cone and represented by an equation.

Here,
The axis of symmetry of a parabola is given by -b/2a
Now. from the given parabolic equation y = 3x² - 6x + 4. we have a = 3 and b  = 6.
Substitute the value in the symmetry equation
Axis of symmetry, x = -(-6)/2(2)
x = 1

Thus, the required axis of the symmetry of the given parabola is x = 1.
