Answer:

The slope equals -⁴/3

Step-by-step explanation:

Slope of the line passing through the origin (0, 0) and (-9, 12):

Slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} = \frac{12 - 0}{-9 - 0} = \frac{12}{-9} = -\frac{4}{3} [/tex]

Slope (m) = -⁴/3

Answer:

t = 8w + w/2

Step-by-step explanation:

Given that :

Weight of bird = w

Amount of water consumed = 8*w = 8w

Amount of food ate = 0.5*w = 1/2w

Hence, the combined weight of water and food (t) consumed by the humming bird :

t = amount of water consumed + amount of food ate

t = 8w + w/2

Answer:

f1 ( x ) valid pdf . f2 ( x ) is invalid pdf

k = 1 / 18 , i ) 0.6133 , ii ) 0.84792

Step-by-step explanation:

Solution:-

A) The two pdfs ( f1 ( x ) and f2 ( x ) ) are given as follows:

- To check the legitimacy of a continuous probability density function the area under the curve over the domain must be equal to 1. In other words the following:

- We will perform integration of each given pdf as follows:

Answer: f1 ( x ) is a valid pdf; however, f2 ( x ) is not a valid pdf.

B)

- A random variable ( X ) denotes the resistance of a randomly chosen resistor, and the pdf is given as follows:

                       if  8 ≤ x ≤ 10

                               0  otherwise.

- To determine the value of ( k ) we will impose the condition of validity of a probability function as follows:

- Evaluate the integral as follows:

                     ... Answer

- To determine the CDF of the given probability distribution we will integrate the pdf from the initial point ( 8 ) to a respective value ( x ) as follows:

To determine the probability p ( 8.6 ≤ x ≤ 9.8 ) we will utilize the cdf as follows:

                   p ( 8.6 ≤ x ≤ 9.8 ) = F ( 9.8 ) - F ( 8.6 )

                   p ( 8.6 ≤ x ≤ 9.8 ) =

ii) To determine the conditional probability we will utilize the basic formula as follows:

               p ( x ≤ 9.8  | x ≥ 8.6 ) = p ( 8.6 ≤ x ≤ 9.8 ) / p ( x ≥ 8.6 )

               p ( x ≤ 9.8  | x ≥ 8.6 ) = 0.61333 / [ 1 - p ( x ≤ 8.6 ) ]

               p ( x ≤ 9.8  | x ≥ 8.6 ) = 0.61333 / [ 1 - 0.27666 ]

               p ( x ≤ 9.8  | x ≥ 8.6 ) = 0.61333 / [ 0.72333 ]

               p ( x ≤ 9.8  | x ≥ 8.6 ) = 0.84792 ... answer

Hope it helps! ;)

You haven't listed the information in the table, but that's okay :). I believe I can still help you.

To find the average score on the test for this group you would have to add up all the test scores listed in the chart, then divide that sum by the number of people in the group.

Here's an example;

I'll make a list of people with some test scores

Jimmy- 80

Andrea- 44

Samuel- 15

Jerica- 65

To find the average of their scores, I'll first add up their points:

80+44+15+65 = 204

Once I've calculated my sum, I will divided that sum by the number of people who took the test. In this case it's 4 different people, so :

204÷4= 51

So in my made up scenario the average score in my group was 51.

Now you can apply this process into your problem.

(Hope this helps :). Please let me know if you need more help on this problem)

Answer:

The equation of the line perpendicular to and passing through its midpoint is equals negative a quarter plus three-quarters.

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

An equation is an expression that shows the relationship between two or more variables and numbers.

The equation for a circle is given as:

(x - h)² + (y - k)² = r²

Where (h, k) is the center of the circle and r is the radius.

The center of the lake is 19 miles east and 3 miles south, i.e. (-19, -3) and the radius is 0.5 miles.

The equation of the lake is:

(x - (-19))² + (y - (-3))² = 0.5²

(x + 19)² + (y + 3)² = 0.25

The equation of the lake with a center 19 miles east and 3 miles south with radius of 0.5 miles is (x + 19)² + (y + 3)² = 0.25

Answer: D.  [tex](x-19)^2+(y+3)^2=0.25[/tex]

Step-by-step explanation:

Let's review what we know:

A circle can be depicted on the coordinate plane with the equation [tex](x-h)^2+(y-k)=r^2[/tex], where:

19 miles east of the origin would be 19 units to the right of the origin on the coordinate plane, as east is the rightwards direction in real life. In short, h = 19.

Let's plug in that value: [tex](x-(19))^2+(y-k)^2=r^2[/tex].

So we know that the x-coordinate defining part of the equation would have to be [tex](x-19)^2[/tex].

Meanwhile, 3 miles south of the origin would be modeled as three units underneath it, because south would be considered "downwards". The y-value (k) would be negative 3.

Putting what we have so far together, the center of the circle would be (19, -3).

Therefore, the y-coordinate defining part of the equation would be [tex](y+3)^2[/tex].

Here's what the equation looks like with the work we've completed so far: [tex](x-19)^2+(y+3)^2=r^2[/tex]

Finally, let's plug in the radius value 0.5.

0.5 * 0.5 = 0.25

Ailani would use the equation [tex](x-19)^2+(y+3)^2=0.25[/tex] to model the lake in relation to the town hall. I hope that makes sense!

Answer:

is 60

Step-by-step explanation:

The equation which represents the transformation of the y-intercept of the parent quartic function,[tex]f(x) = x^4[/tex]   is given by     [tex]g(x)=(x-3)^4-1[/tex] .

Transformation is the act or process of changing completely. In this also the graph changes or transform.

We have,

Parent Quadratic equation [tex]f(x)=x^4[/tex]

And

It translated [tex]3[/tex] units to the right and [tex]1[/tex] unit down.

And the parent quadratic function is in the form of [tex]f(x) = a(x-h)^4 + k.[/tex]

Here,

"h" tells if the vertex of the parabola is going left or right.

"k" determines if the vertex of the parabola is going up or down.

So, According to the question;

We have,

[tex](a)[/tex]   [tex]3[/tex]  units to the right

[tex](b)[/tex]   [tex]1[/tex] unit down

So,

Equation would be  [tex]g(x)=(x-3)^4-1[/tex]  means that you have moved the vertex of the parabola  [tex]3[/tex]  units to the right and  [tex]1[/tex] units down.

(Always remember if moving right means [tex](x-3)[/tex] sign would be minus because in parent quadratic function is in the form of [tex]f(x) = a(x-h)^4 + k[/tex] we have minus sign.)

Hence, we can say that the equation which represents the transformation of the y-intercept of the parent quartic function,[tex]f(x) = x^4[/tex]   is given by     [tex]g(x)=(x-3)^4-1[/tex] .
