Does this scatter plot show a linear association explain yes or no

Answers

No, The scatter plot does not show a linear association

What is graph?

A graph is way of presenting data used by several disciplines.

There are many types of graphs and scatter plot is one of them.

scatter plot can be defined as set of dots plotted on a horizontal and vertical axis.

scatter plots can demonstrate the degree of connection, if any, between the values of observed quantities or events, they are crucial in statistics

The scatter plot does not show a straight line graph or a linear function. tracing the line shows a inverted shape of "s" which is not associated with linear functions.

23X-17 = 15X+7 give me the solution

Answers

Answer: x=3

Step-by-step explanation:

Simplify equation to get 8x=24. Divide 24 by 8 to get x=3. Please give brainliest :D

Answer:

Step-by-step explanation:

23X - 17 = 15X + 7

First add 17 to both sides to isolate the variable (usually the one with the bigger coefficient is best)

23X = 15X + 24

subtract 15x from both sides to combine 23X and 15X terms

8X = 24

Divide by 8 to solve

X = 3

If f is continuous everywhere, f'(3) = 0 and f" (3) = 4, then there must be a local minimum at z = 3.​

Answers

Answer:

True

Step-by-step explanation:

f'(3) = 0 says the tangent line at x = 3 is horizontal.

f"(3) = 0 means the graph of  f  is concave up at x = 3.

The function g(x) is continuous on the closed interval [8, 10] and differentiable on the open interval

What is g(10) given g'(8.5) = -9 and g(8) = 6?

Answers

Answer:

g(10) = -12

Step-by-step explanation:

Mean Value Theorem

If f is continuous on [a, b] and differentiable on (a, b), then there is a number c  such that a < c < b and:

[tex]f'(c)=\dfrac{f(b)-f(a)}{b-a}[/tex]

We are told that the function g(x) is continuous on the closed interval [8, 10] and differentiable on the open interval (8, 10).

Therefore:

a = 8b = 10

Given:

g'(8.5) = -9g(8) = 6

As 8 < 8.5 < 10 then c = 8.5:

[tex]\begin{aligned} \implies g'(8.5)=\dfrac{g(10)-g(8)}{10-8}&=-9\\\\\dfrac{g(10)-6}{2}&=-9\\\\g(10)-6&=-18\\\\g(10)&=-12\end{aligned}[/tex]

in a recent study, it was found that 87.3% of all homes have a large-screen tv. a sample of 28 homes is selected. the data follows a binomial distribution. a) what is the mean of the distribution? (round your answer to 3 decimals.)

Answers

The mean of the distribution is 24.444.

Given, that 87.3% of all homes have a large-screen tv. a sample of 28 homes is selected.

Now, we have to find the mean of the distribution

As, we know

E(x) = np

where, n is the sample and p is the probability of success

So, n = 28 and p = 87.3% = 0.873

Now, on using the formula we get,

E(x) = (28)(0.873)

E(x) = 24.444

So, the mean of the distribution is E(x) = 24.444

Hence, the mean of the distribution is 24.444.

Answers

Answer:

x= 40° y= 66° z=106° ....

The value of angles are x = 40° , y = 66°, z = 106°

Since there are two parallel lines and two intersecting lines forming a triangle we will use the properties of lines and triangles to find out the value of x,y,z. First of all y = 66° because of the vertical angle theorem, which means that adjacent angles formed by the intersection of two lines are supplementary or equal to 180° degrees. The third angle of the triangle formed is 74°. Using the sum of all angles of the triangle is equal to 180° we can find the third angle of triangle x which is equal to 40°. Now z can be found using the property sum of two opposite interior angles which will come out to be 106°. Hence by this, we can find all the angles.

A rectangle that maximize the enclosed area has a length 800 yards and width is 800 yards. The maximum area is 640,000 square yards.

In the given question we have to find the maximum area of the rectangular area.

Liana has 3200 yards of fencing to enclose a rectangle.

So we know that the perimeter of rectangle is

P= 2(l+b)

Let length of the rectangle is x yards and width is y yards.

So the equation should be

2(x+y) = 3200

Divide by 2 on both side we get

x+y = 1600................(1)

As we know the area of rectangle is

A = xy

From the equation the value of y is 1600-x.

Now putting the value of y

A = x(1600-x)

A = 1600x-x^2

On differentiating

dA/dx = 1600-2x

Putting dA/dx=0

1600-2x=0

Subtract 1600 on both side we get

-2x= -1600

Divide by -2 on both side we get

x = 800 yards

Now putting the value of x in the y=1600-x

y=1600-800

y=800 yards

So the maximum area is

A= 800*800

A= 640,000 square yards

Hence, a rectangle that maximize the enclosed area has a length 800 yards and width is 800 yards. The maximum area is 640,000 square yards.

The factored form of x² + 2x - 15 is (x + 5)(x - 3).

What is factorisation?

Factorisation is a process of finding the factors of algebraic equations and representing them in simple form instead of expanded form.

Therefore, let's factor x² + 2x - 15

x² + 2x - 15

let's find two numbers we can add to get 2 and multiply to get - 15. The two numbers are -3 and 5.

Therefore,

x² - 3x + 5x - 15

x(x - 3) + 5(x - 3)

(x + 5)(x - 3)

Therefore,

A line is subdivided according to the golden ratio, with a smaller piece having a length of 5 meters. What is the length of the entire line?

Answers

The length of the entire line which is subdivided according to golden ratio is 13.09 meters.

What is Golden Ratio?

The golden ratio is a special number approximately equal to 1.618

We find the golden ratio when we divide a line into two parts so that, the whole length divided by the long part is also equal to the long part divided by the short part

Let smaller part of a line be b and long part be a

Golden ratio = a + b/a = a/b = 1.618

According to the given question:

Length of smaller part of line = 5 meters

Let the longer length of the line be x

∴ Total length of line = 5 + x

Using Golden ratio to find the entire length of line

x/5 = 1.618

x = 8.09

Calculating length of entire line = 5 + x = 5 + 8.09 = 13.09

∴ Length of entire line is 13.09 meters

If we have a Set A, it is a subset of Set B if every element in A is also in B. Set A is a proper subset of Set B if it is a subset of Set B but not equal to Set B.

Using the above information, we know that the proper subset of {7, 11, 15, 19} cannot be itself, so we can rule out the second option.

All of the other options are sets where every element of that set is also an element of {7, 11, 15, 19}. The 3rd option is an empty set, which is a proper subset of any set other than itself, so it is a proper subset of {7, 11, 15, 19}.

Therefore, all of the options except for {7, 11, 15, 19} are valid.
