WHAT IS THE FORMULA I CANT --

Using proportions and the percentage concept, it is found that:

A proportion is a fraction of a total amount, and equations can be built to find the desired measures in the problem using a rule of three, that can be either direct(cross multiplication) or inverse(line multiplication), deriving from proportional relationships. One example of application of proportions is for percentage problems.

This is because a percentage of an amount a divided by a total amount b is given by the following proportion:

P = a/b x 100%.

From the image, we have that 3 out of 12 apples are of the Jonagold variety, hence:

3/12 x 100% = 0.25 x 100% = 25%.

Each apple in the image is equivalent to 7 apples, hence:

9 x 7 = 63.

63 apples are not of the Jonagold variety.

The scatterplot is the correct answer.

A scatter plot uses dots to represent values for two different numeric variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. Scatter plots are used to observe relationships between variables.

The dots in a scatter plot not only report the values of individual data points but also patterns when the data are taken as a whole.

Identification of correlational relationships is common with scatter plots. In these cases, we want to know, if we were given a particular horizontal value, what a good prediction would be for the vertical value.

The constant of proportionality for the relationship plotted, on the graph is 25 and the distance in 10 seconds is 250

The graph is the given parameter

On the graph, we have the following point

(x, y) = (2, 50)

The constant of proportionality for the relationship plotted, on the graph is represented with k, and the formula is

k = y/x

This gives

k = 50/2

Evaluate

k = 25

Substitute k = 25 in k = y/x

25 = y/x

When x = 10. we have

25 = y/10

This gives

y = 250

Hence, the constant of proportionality for the relationship plotted, on the graph is 25 and the distance in 10 seconds is 250

Answer:

22°, 79° and 79°

Step-by-step explanation:

Let x  be the vertex angle and y each of the congruent angles.

The sum of all angles =180°

So x + y + y = 180

x + 2y = 180 ·········· Equation (1)

Given "The measure of each of the congruent angles of an isosceles triangle is 9 less than 4 times the vertex angle", the equation is

y = 4x - 9

Substitute for y in terms of x in equation 1

⇒ x + 2(4x - 9) = 180

⇒ x + 8x - 18 = 180

⇒ 9x - 18 = 180

⇒ 9x = 180 + 18

⇒ 9x = 198

⇒ x = 198/9 = 22

So vertex angle is 22°

Substituting for x in Equation 1:
22 + 2y = 180
2y = 180 - 22
2y = 158
y = 158/2
y = 79°

So each congruent angle is 79°

Using the relation between velocity, distance and time, it is found that the average speed of the record winner of the wheelchair division was of 20.04 miles per hour.

"The record for the Boston Marathon’s wheelchair division is 1 hour,

18 minutes, and 27 seconds.

The Boston Marathon is 26.2 miles long. What was the average speed of the record winner of the wheelchair division?"

Velocity is distance divided by time, that is:

v = d/t.

For this problem, we have that:

Hence the velocity is given by:

v = 26.2/1.3075 = 20.04 miles per hour.

Answer: The value of p(x) = (-2,6) or p(x) = (-2,0)

Step-by-step explanation:

Given that,

p(x) = x^3-4x^2-8x

p(x) = [tex]x^{3}[/tex] - [tex]4x^{2}[/tex] - 8x

and replace with '0'.

x^3-4x^2-8x = 0

Now, factorizing equation is,

(x+2) ([tex]x^{2}[/tex] - 6x) = 0

(x+2) = 0

x= -2

Therefore, x = -2

and,

([tex]x^{2}[/tex] -6x) = 0

([tex]x^{2}[/tex] -6x+0) = 0

using quadratic formula = - [b ± √[tex]b^{2}[/tex]-4ac] / 2a

substitute the values,

a = 1, b = -6 , c = 0

                          p(x) = - [-6 ± √[tex]-6^{2}[/tex]-4.1.0] / 2.1

                           p(x) = - [-6 ± √36-4.1.0] / 2.1

                            p(x) = - [-6 ± √36-(0)] / 2.1

                             p(x) = - [-6 ± √36] / 2.1

                             p(x) = - [-6 ± 6] / 2

                              p(x) = [6 ± 6] / 2

                             p(x) = 3 ± 3

Therefore, p(x) = 3+3 = 6

                  p(x) = 3-3 = 0

So, that we can say the value of p(x) = (-2,6) or p(x) = (-2,0).

The magnitude of the sum of these two vectors is approximately 11.791 units.

In this question we have the representations of two vectors on a Cartesian plane, of which we must find the magnitude of the two vectors. There are different methods to find it, we decide to use a vectorial method. First, sum the two vectors:

R(x, y) = A(x, y) + B(x, y)

R(x, y) = 7.70 · (cos 27.8°, sin 27.8°) + 16.3 · (- sin 20°, - cos 20°)

R(x, y) = (6.811, 3.591) + (- 5.574, - 15.317)

R(x, y) = (1.237, - 11.726)

R = √[1.237² + (- 11.726)²]

R ≈ 11.791

The probability that only one of the counter is white is 6/11.

So we know that there are 11 counters, 5 of them are white, 6 are not white.

Let's assume that first we take the white one, the probability is equal to the quotient between the number of white counters and the total number of counters, so we have:

p = 5/11

Now for the second one, we don't want to take a white one, so here the probability is equal to the quotient between the number of non-white counters (6) and the total number of counters (now there are 10, because we took one)

q = 6/10

The joint probability is the product of the individual probabilities, this is:

P = p*q

And, also notice that there are 2 permutations:
