When water flows across farmland, some of the soil is washed away, resulting in erosion. Researchers released water
across a test bed at different flow rates and measured the amount of soil washed away. The following table gives the
flow (in liters per second) and the weight (in kilograms) of eroded soil:

Answers

Answer 1

The correlation coefficient between flow rate and amount of eroded soil is:

0.967.

Correlation coefficients

The correlation coefficient is an index that measures correlation between two variables, assuming values between -1 and 1.

If it is positive, the relation is positive, meaning that the variables are direct proportional. If it is negative, the variables are inverse proportional.

If the absolute value of the correlation coefficient is greater than 0.6, the relationship between the variables is strong.

Given a data-set of two points, the correlation coefficient is found inserting points of the data-set into the calculator. In this problem, the points in the data-set are given as follows:

(0.31, 0.82), (0.85, 1.95), (1.26, 2.18), (2.47, 3.01), (3.75, 6.07).

Using a calculator, the coefficient is given as follows:

0.967.

Hence the last option gives the correct coefficient.

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. The word per cent means per 100. It is denoted by the symbol “%”.

The total percentage of two or more ratios in a thesame entity is 100. For example, In a population, 28% has HBP (high blood pressure)

This means that number of those that do not have HBP will be 100 - 28 = 72%

86% of those who did not have HBP exercise at least 90 minute per week i.e

86% of no HBP ,exercise >or = 90 = (86/100) × 72 = 62%( nearest whole number)

Those that do exercise <90 minute per week = 72-62= 10%

32% of those with HBP exercise at least 90 minute( >or = 90 minutes) =( 32\100) × 28= 9%( nearest whole number)

Those with HBP and exercise <90= 28- 9= 19%

The length of segment AC is 2.96 units

How to determine the side length AC?

From the question, the given parameters are

Line segment AB = 7 units

Angle A = 65 degrees

The line segment AC can be calculated using the following cosine ratio

cos(Angle) = Adjacent/Hypotenuse

Where

Adjacent = Side length AC

Hypotenuse = Side length AB

So, we have

cos(65) = AC/AB

compute the critical points of (x-2)^2+5

to find all critical points, first compute f(x)

flying against the wind, an airplane travels 7840 kilometers in 8 hours. flying with the wind, the same plane travels 5280 kilometers in 4 hours. what is the rate of the plane in still air and what is the rate of the wind?

Answers

Answer:

The rate of the plane in still air is 1150km/hr and the rate of the plane in the wind is 170km/hr.

Explanations:

The formula for calculating distance is expressed as:

[tex]\begin{gathered} dis\tan ce=\text{speed}\times\text{time} \\ d=st \end{gathered}[/tex]

Let the rate of the plane in still air be "x"

Let the rate of the plane in the wind be "y"

if flying against the wind, an airplane travels 7840 kilometers in 8 hours, then;

8 (x - y) = 7840

x - y = 980 ........................ 1

If flying with the wind, the same plane travels 5280 kilometers in 4 hours

4 (x + y) = 5280

x + y = 1,320 ......................2

Add both equations:

x + x = 980 + 1320

2x = 2,300

x = 2300/2

x = 1150 km/hr

Substract x = 1150km/hr into equation 1.

x - y = 1320

1150 + y = 1320

y = 1320 - 1150

y = 170km/hr

Hence the rate of the plane in still air is 1150km/hr and the rate of the plane in the wind is 170km/hr

What is the transformation of a graph?

Transformation is rearranging a graph by a given rule it could be either increment of coordinate or decrement or reflection.

If we reflect any graph about y = x then the coordinate will interchange it that (x,y) → (y,x).

If a function f(x) is transformed by funciton g(x) as shown,

g(x) = f(x+a)

For a>0, then the graph of f(x) shifts left by "a" unit, while if a<0, then the graph of f(x) shifts right side by "a"units.

As per the given function,

g(x) = f(x + 2)

Since 2  > 0 therefore the function will shift 2 units left.

Hence "The graph of g(x) is the graph of ​f(x)​ translated 2 units left by the operation g(x)=f(x+2)".

Find equation of the parabola: y =
When x 18, what is the value of y:
What is the average rate of change between x = -2 and x = 18:

Answers

The equation of the parabola is y = 1/5( x + 2 )² + 8.

When x = 18 the value of y is 88 and the average rate of change between x = - 2 and x = 18 is 4.

The general equation of the parabola is given as:

y = a(x – h)² + k where ( h, k ) is the vertex of the parabola.

We have, the vertex as ( - 2, 8 ) and the parabola passes through ( 8, 28 ).

Then,

y = a(x – h)² + k

28 = a( 8 - (-2) )² + 8

28 = a(10)² + 8

28 - 8 = a(10)²

100a = 20

a = 20/100 = 1/5

Therefore, the equation of the parabola will be:

y = a(x – h)² + k

y = 1/5( x + 2 )² + 8

Now, when x = 18:

y = 1/5( x + 2 )² + 8

y = 1/5( 18 + 2 )² + 8

y = 1/5( 20 )² + 8

y = 80 + 8 = 88

Now, the change between x = - 2 and x = 18:

Then,

y = f(18) = y = 1/5( 18 + 2 )² + 8 = 1/5(20)² + 8 = 88

And;

y = f( - 2) = 1/5( -2 + 2 )² + 8 = 1/5(0)² + 8 = 8

Therefore the average rate of change between x = - 2 and x = 18 will be:

= [ f(18) - f(-2) / ( 18 - (-2) ) ]

= ( 88 - 8 ) / 20

= 80/20

= 4

Answer

Scale factor = 3.5

Explanation

Scale factor expresses how much the copy/image of the original figure is bigger or smaller than the original figure.

If the scale factor is more than 1, then the image is an enlargement of the original figure.

But if the scale factor is less than 1, then the image is a reduction of the original figure.

Mathematically,

Scale factor = (Length of a side of the image or scaled copy)/(Corresponding length of that side on the original figure)

Length of a side of the image or scaled copy = 56

Corresponding length of that side on the original figure = 16

Scale factor = (Length of a side of the image or scaled copy)/(Corresponding length of that side on the original figure)

Scale factor = (56/16) = (7/2) = 3.5

Answers

The length of the first piece is 5 inches when a 43-inch piece of steel is cut into three pieces.

According to the question,

We have the following information:

A 43-inch piece of steel is cut into three pieces so that the second piece is twice as long as the first piece, and the third piece is three inches more than five times the length of the first piece.

Now, let's take the length of the first piece to be x inches (as shown in the figure).

Length of second piece = 2x inches

Length of third piece = (3+5x) inches

Now, we have the following expression for addition:

x + 2x + 3 + 5x = 43

8x+3 = 43

8x = 43-3

8x = 40

x = 40/8

[tex]\begin{gathered} x+1=1 \\ \frac{x}{4}=0 \\ \text{And as }2>0,\text{ (0, 2) is NOT a solution of the system.} \end{gathered}[/tex]

For (-3, 8)

In this case, x=-3 and y=8.

[tex]\begin{gathered} x+1=-2 \\ \frac{x}{4}=-\frac{3}{4} \\ \text{As }8>-\frac{3}{4},\text{ this means that (-3, 8) is NOT a solution of the system.} \end{gathered}[/tex]

For (2,5)

In this case, x=2 and y=5.

For (-7, -4)

In this case, x=-7 and y=-4.

For (6, -1)

We have that x=6 and y=-1.

Use one of the specified points in your equation. Write your answer using integers, proper fractions, and improper fractions. Simplify all fractions.

Answers

Answer:

y - 1 = -8/3(x - 10)

also valid:

y - 9 = -8/3(x - 7)

Step-by-step explanation:

Point-slope equation is a fill-in-the-blank formula that is sort of a shortcut for writing the equation of a line. Point-slope is named that bc you fill in a point and the slope.

Point-slope Eq:

y - Y = m(x - X)

fill in the slope for the m and fill in any point on the line for the X,Y.

First slope:

Slope is y-y over x-x

9-1 / 7-10

= 8/ -3

= -8/3

So slope is -8/3 fill that in for the m.

y -Y = -8/3(x-X)

Pick one of the points (either one it totally doesn't matter)

Let's use (10,1)

fill in 10 for X and 1 in place of Y.

the y in the very front stays a y and the first x in the parentheses stays an x, so there will be two variables in your completed answer.

y - 1 = -8/3(x - 10)

make sure the parentheses on the right is beside the -8/3 fraction and is NOT written on the bottom, beside the 3 only.

Determine the x-intercept for 3x + 2y = 14.A) (7,0) B) (0,7) C) (14/3,0) D) (0,14/3)

Answers

By definition, when the line intersects the x-axis, the value of "y" is:

[tex]y=0[/tex]

Knowing this, you can substitute that value of "y" into ithe equation given in the exercise:

[tex]\begin{gathered} 3x+2y=14 \\ 3x+2(0)=14 \end{gathered}[/tex]

Now you must solve for the variable "x" in order to find the x-intercept. This is:

[tex]\begin{gathered} 3x+0=14 \\ 3x=14 \\ x=\frac{14}{3} \end{gathered}[/tex]

Then, you get this point:

[tex](\frac{14}{3},0)[/tex]

The answer is: Option C.
