Cora is playing a game that involves flipping three coins at once let the random variable H be the number of coins that land showing heads. Here is the probability distribution for H.

Answers

Answer 1

Answer:

[tex]P(H <3) = 0.875[/tex]

Step-by-step explanation:

Given (Missing from the question):

[tex]\begin{array}{cc}{H}&{P(H)&0&0.125&1&0.375&2&0.375&3&0.125\end{array}[/tex]

And the required question is:

Determine the P(H < 3)

P(H <3) implies that: P(H = 0) or P(H = 1) or P(H = 2)

So, we have:

[tex]P(H <3) = P(H = 0) + P(H = 1) + P(H = 2)[/tex]

[tex]P(H <3) = 0.125 + 0.375 +0.375[/tex]

[tex]P(H <3) = 0.875[/tex]

Over the next 17 months, Eli needs to read more

than 102 e-books. The inequality 17x > 102

represents the number of e-books he needs to

read per month. Solve the inequality to find the

number of e-books Eli needs to read per month.

Answers

Answer:

Number of e-books Eli needs to read per month is Greater than 6

Step-by-step explanation:

Given - Over the next 17 months, Eli needs to read more  than 102 e-books.

             The inequality 17x > 102 represents the number of e-books he  

              needs to  read per month.

To find - Solve the inequality to find the  number of e-books Eli needs to  

               read per month.

Proof -

As given, Over the next 17 months Eli need to read more than 102 e-books

i.e 17x > 102

⇒x > [tex]\frac{102}{17}[/tex]

⇒x > 6

∴ we get

Per month Eli needs to read more than 6 e-books.

PLZ HELP -geometry- Find the coordinates of the intersection of the diagonals of parallelogram GHJK with vertices G(1,3), H(4,3), J(5,1), and K(2,1).

The coordinates are ( , ).

Answers

Answer:

The coordinates of the intersection of the diagonal of the parallelogram are [tex]M(x,y) = (3,2)[/tex].

Step-by-step explanation:

Diagonals are represented by line segments GJ and KH. Since quadrilateral is a parallelogram, then coordinates of the intersection are located at midpoint of each diagonal ([tex]M(x,y)[/tex]). That is:

[tex]M(x,y) = G(x,y) + \frac{1}{2}\cdot \overrightarrow {GJ}[/tex]

[tex]M(x,y) = G(x,y) +\frac{1}{2}\cdot [J(x,y)-G(x,y)][/tex] (1)

If we know that [tex]G(x,y) = (1,3)[/tex] and [tex]J(x,y) = (5,1)[/tex], the coordinates of the intersection of the diagonals of the parallelogram are:

[tex]M(x,y) = (1,3) +\frac{1}{2}\cdot [(5,1)-(1,3)][/tex]

[tex]M(x,y) = (1,3) +\frac{1}{2}\cdot (4,-2)[/tex]

[tex]M(x,y) = (1,3) +(2,-1)[/tex]

[tex]M(x,y) = (3,2)[/tex]

There is another form:

[tex]M(x,y) = K(x,y) +\frac{1}{2}\cdot \overrightarrow{KH}[/tex]

[tex]M(x,y) = K(x,y) + \frac{1}{2}\cdot [H(x,y)-K(x,y)][/tex] (2)

If we know that [tex]K(x,y) = (2, 1)[/tex] and [tex]H(x,y) = (4,3)[/tex], the coordinates of the intersection of the diagonals of the parallelogram are:

[tex]M(x,y) = (2,1) + \frac{1}{2}\cdot [(4,3)-(2,1)][/tex]

[tex]M(x,y) = (2,1) + \frac{1}{2} \cdot (2,2)[/tex]

[tex]M(x,y) = (2,1) + (1,1)[/tex]

[tex]M(x,y) = (3,2)[/tex]

Therefore, the coordinates of the intersection of the diagonal of the parallelogram are [tex]M(x,y) = (3,2)[/tex].

What is Trigonometry?

The study of triangles' relationships to their angles, lengths, and heights is known as trigonometry. In particular for right-angled triangles, it includes ratios, functions, identities, and formulas to solve issues based on it.

Given:

Base= 30 feet

Angle = 65

Using Trigonometry

tan 65 = P / B

P = B (tan  65)

P = 30 ( tan 65)

or, x= 30 tan 65

Answer:

240 cm², A = 300 cm², and 540 cm²

Step-by-step explanation:

1) The area of a parallelogram is A = bh, so:

A = (20)(12)

A = 240 cm²

2) Similarly, the area of a rectangle is A = bh, so:

A = (15)(20)

A = 300 cm²

3) The composite area is the sum of both the rectangle's area and the parallelogram's area, so:

240 cm² + A = 300 cm² = 540 cm²

C. Is true

Step-by-step explanation:

To figure this out, you just need to extend the graph. You can do this by extending the already existing line or find the equation of the line. I found the equation of the line which is y = 0.5x . Now once you have the extended graph, you need to graph the given points.

(25,10)

(10,25)

(20,10)

(15,3)

After graphing these points, check which one is on the line. You would see that the point (20,10) is on the line. Now that you know this, you figure out which answer had this point. The answer that has this point is answer C.

What is the image of (- 4, 3) after a dilation by a scale factor of 2 centered at the origin?

Answers

Answer: (-8,6)

Step-by-step explanation:

Question: What is the image of (-4,3)(−4,3) after a dilation by a scale factor of 22 centered at the origin?

Dilation: multiply each coordinate

(x,y)\rightarrow (2x,2y)

(x,y)→(2x,2y)

Dilations multiply by scale factor

(\color{red}{-4},\color{blue}{3}) \rightarrow (2\cdot \color{red}{-4},2\cdot \color{blue}{3})=\mathbf{(-8,6)}

(−4,3)→(2⋅−4,2⋅3)=(−8,6)

This was on my delta math so i hope this helps

The image of the point (- 4, 3) after dilation will be (-8,6).

What is dilation?

Dilation is the process of increasing the size of an object while maintaining its shape. Depending on the scale factor, the object's size can be increased or decreased.

The scale factor is defined as the proportion of the new image's size to that of the previous image. decision-making.

Given point is  (-4, 3). The dilation of the point will be calculated as below:-

Dilation:- multiply each coordinate.

(x,y)→(2x,2y)

Dilations multiply by a scale factor

(−4,3)→(2⋅−4,2⋅3)=(−8,6)

Therefore, the image of the point (- 4, 3) after dilation will be (-8,6).
