If another age of 33 is added to the data, how would the mean be impacted?

The mean would increase in value to about 24.6.
The mean would increase in value to about 27.1.
The mean would stay the same value of about 22.5.
The mean would stay the same value of about 23.8.

Answers

Answer 1
The correct answer is B. The mean would increase in value to about 27.1
If another age of 33 is added to the data, the new mean would be (17 + 17 + 18 + 19 + 22 + 23 + 25 + 27 + 32 + 38 + 33) / 11 = 27.1.
Answer 2

Step-by-step explanation:

the mean would increase to about 24.6 is the answer

if u add all the ages together including the extra 33 you get 271. if u divided this by 11 you get 24.636...

In triangle ABC, let the angle bisectors be BY and Cz. Given AB = 8, $AY = 6, and CY = 3, find BZ and BC.
please help soon

Answers

Answer:

Step-by-step explanation:

hhl

The length of BC = 4 units and the length of BZ = 2.5 units.

How to solve

We have been handed a triangle ABC for this question.

The angle bisectors BY and CZ have been provided to us.

Moreover, AB = 8, AY = 6, and CY = 3.

We must determine how long BC and BZ are.

The angle bisector theorem is used.

According to the angle bisector theorem we have;

AY/CY = AB/BC,BZ/AZ = BC/AC

Consider,

AY/CY = AB/BC

6/3 = 8/BC

BC = 8/2

BC = 4 units

Now,

AC = CY + AY

AC = 3 + 6

AC = 9

and,

AZ = AB - BZ

AZ = 8 - BZ

consider BZ/AZ = BC/AC,

BZ/(8 - BZ) = 4/9

9 BZ = 32 - 4 BZ

(9 + 4)BZ = 32

13 BZ = 32

BZ = 2.5

Therefore, the length of BC = 4 units, and the length of BZ = 2.5 units.

The surface of the cuboid below is 128cm squared. Find the length x.

Answers

Answer:

x = 6 cm

Step-by-step explanation:

The surface area: 128 cm^2

32 + 16x = 128

Note: The surface area of a cuboid consists of 6 faces

16x=96 -> x = 6

Answer:

Step-by-step explanation:

The total surface area = 2(lb+lh+bh)

With given information, 2(4x+4x+4*4) = 128

=> 2(8x+16) = 128

=> 16x + 32 = 128

=> 16x = 96

=> x = 6

Therefore, the length = 6

what is the median weight of the mice ?

carrie records the weight s , in ounces , of 8 mice for a science project in the list

below . what is the median weight of the mice ?

⇔ 0.71 , 0.66 , 0.63 , 0.73 , 0.70 , 0.68 , 0.66 , 0.66 ⇔

Answers

Answer: 0.66

Step-by-step explanation:

The median is the MIDDLE NUMBER of a group of numbers.
Grouping the mice weights in order from least to greatest can help solve the problem quickly.

-> 0.63, 0.66, 0.66, 0.66, 0.68, 0.7, 0.71, and 0.73.

After that, you cross out each of the numbers starting with 0.63 and 0.73 going toward the middle, to get the odd one out, which is 0.66.

So, 0.66 is the median weight of the mice.

answer : the median is 0.67


0.71 , 0.66 , 0.63 , 0.73 , 0.70 , 0.68 , 0.66 , 0.66


first you would arrange it from least to greatest :

0.63, 0.66, 0.66, 0.66, 0.68, 0.7, 0.71, 0.73

Since you have an even set of numbers you take the two numbers in the middle and find out which number is exactly in between those, so in this case it would be 0.67

Answers

Answer: 20% discount.

Step-by-step explanation:

We need to set up a proportion to figure out how much percent discount they have.

We can do that by taking the price the customer pays and dividing that by the original price.

So, 246.4/308.

This gives us .8 or 80%, but that is not the answer.

They are paying 80% meaning to find the discount we would subtract 80% from 100% and get 20%.

Frabjous Day

Everyone at our lunch table was silent; our small world had been rocked to the core. Derrick, president of the computer chess club stared at his lunch tray as if it held some sort of threatening, inedible concoction from another planet. Laurel, the leader of my literary discussion group, was pale, looking as though she were coming down with some nasty illness. We had just learned that Frabjous Day, the best and only bookstore in our small town might have to close. Business was just too slow. (The charming name, of course, was from Lewis Carroll's nonsense poem "Jabberwocky.") People were purchasing books online or downloading them to their e-readers. No one seemed interested in a real bookstore anymore. This impacted us not only because our groups met at Frabjous Day, but also because we believed that the bookstore added value to life and the community.

"We need to save Frabjous Day, and we have to get all our classmates involved in the effort," Laurel said, breaking the painful silence. She was right, but the obstacles in our way made climbing Mt. Everest look like a walk in the park. We represented just a few people at our school, and we had no idea how to reach everyone.

"My brother is always quoting his basketball coach," Derrick said, "One word that keeps coming up is 'strategy.' Maybe that's what we need: a unique strategy to get everyone to recognize the value of Frabjous Day and become involved in the store."

I admired the idea immediately. Come to think of it, my literary group had recently read a classical book on strategy called The Book of Five Rings. It was written in the 1600s by a Japanese swordsman, and it describes the necessity of discipline, perception, and outthinking your opponent. I remembered a quote about there being more than one path to the mountaintop, which seemed appropriate.

After several days, we had developed a plan. First we talked with our principal and then with the owner of Frabjous Day. Finally, we set up a big display at school under the banner STRATEGIES FOR SUCCESS. We exhibited books like the Five Rings and a book written by a championship-winning basketball coach. We had a book of political writings by Gandhi and another on effective environmental conservation. I personally selected biographies of successful people, including a biography on a fabulously successful actress. We had a big sign that read: "Build strategies for succeeding at what you love! Visit Frabjous Day this afternoon after school. You'll learn a lot and enjoy free sandwiches and cookies." Laurel thought of that last part because, after all, food always brings people together.

Crowds of students turned up that afternoon. We knew we needed them to actively commit to saving the store. Derrick, a master at chess strategy, devised a personalized group approach for the athletes. He showed students how to play a computerized strategy game, explaining how to use the idea on a personal or athletic level. Under a sign reading "Have a blind date with a book," Laurel set up a display of books covered in brown paper, with a brief handwritten description of the contents that was purposefully vague, yet very enticing. I invited a TV personality who grew up in our town. Everyone wanted to meet a real celebrity! Even better, people got excited about helping each other and the bookstore.

Our local librarian, Mr. Chung, contributed the best idea of all. His college roommate had been the now famous guitarist and singer Joel J. Mr. Chung and Joel were also best friends with Cecily Armstrong, whose latest mystery novel was on the best-seller list. Mr. Chung printed out raffle tickets to be given with each book sold. At the end of the year, some lucky winner would have his or her name in an original Joel J song lyric. Another lucky winner would be a character in Ms. Armstrong's next novel. The raffle was a huge success. There was no doubt that Frabjous Day was going to have many frabjous days ahead.

Step-by-step explanation:

Part A. The technique on how to find the equation that only applies to point C and F, is to create a line or curve that only includes two of these points. In this case, I created a random line that isolates points C and F from the rest of the points. First, we have to find the equation of the line by choosing at least two points on the line. Using the slope-
intercept form: y = mx + b, where m is the slope, Ay/
Ax and b is the y-intercept. Let's choose the red points: Point 1(3,3) and Point 2(-4,-4).
m = (-4 - 3)/(-4 - 3) =1
Then, from the graph, we can see that the intercept is O. So, the equation of the line is y=x. Now, let's find the inequality symbol that applies to C(2,1) and F(3,-4).
Point C;
y? x
1?2
1<2
Point F:
y? x
-4?3
-4<3
That means the inequality symbol should be <. The complete equation is then yPart C. For y < 7x - 4, ignore the equality symbol first and graph the line. Assign random values of x, then you get corresponding values of y. Plot them as shown in the second picture. The line is shown in red. Next, test the equation by choosing a random point. Let's choose the purple point at (4,3).
3?714)-4
3? 24
3 < 24
Thus, it applies to the purple point, and all the other areas to that area. The shaded region are all solutions of the inequality. So, Erica is only interested in points E, C and F.

B
Jackie is correct. She rewrote the expression 5(3x −4) 5\left(3x\ -4\right)\5(3x −4) by combining 555 to and 3x3x3x to get 8x8x8x . She then calculated 4−3=14-3=14−3=1 and added 222 for a final answer of 8x +38x\ +38x +3 .

C
Jackie is not correct. She expression 5(3x −4) 5\left(3x\ -4\right)\5(3x −4) should be rewritten as 15x−2015x-2015x−20 When 222 is added, the final answer is 15x−1815x-1815x−18 .

D
Jackie is not correct. She expression 5(3x −4) 5\left(3x\ -4\right)\5(3x −4) should be rewritten as 15x−415x-415x−4 When 222 is added, the final answer is 15x−215x-215x−2 .

Answers

The correct option for the above question is Option D

"Jackie is not correct. She expression 5(3x −4) should be rewritten as 15x−4. When 222 is added, the final answer is 15x+218."

To see why, let's simplify the expression step by step:

5(3x - 4) can be simplified as follows:

= 15x - 20 (distributing 5)

Adding 2 to this expression gives:

15x - 20 + 2 = 15x - 18

Therefore, the correct expression after adding 2 is 15x - 18, not 8x + 3 or any of the other options given.

Therefore, option D is correct and Jackie is not correct in her approach.

Get it right I Will mark brainly. But!! If you copy and paste I will report and take all your points!

Answers

Answer:

17/15

Step-by-step explanation:

To multiply the mixed number [tex]2\frac{5}{6}[/tex] by the fraction [tex]\frac{2}{5}[/tex], you first need to convert the mixed number into an improper fraction.

To do this, you multiply the whole part (2) by the denominator of the fractional part (6) and then add the numerator of the fractional part (5).

(2 x 6) + 5 = 17

So, [tex]2\frac{5}{6}[/tex] can be written as an improper fraction: [tex]\frac{17}{6}[/tex].

Now that both numbers are fractions, you can multiply them together:

[tex]\frac{17}{6}[/tex] x [tex]\frac{2}{5}[/tex] = (17 x 2) ÷ (6 x 5) = [tex]\frac{34}{30}[/tex]

This fraction can be simplified by dividing both the numerator and denominator by their GCD, which is 2:

(34 ÷ 2) ÷ (30 ÷ 2) = [tex]\frac{17}{15}[/tex]

So, the result of multiplying 2 5/6 by 2/5 is the improper fraction 17/15 or the mixed number 1 and 2/15.

Kinetic molecular theory postulates are written for ideal gas behavior. In reality, gases to not behave ideally. For example, water molecules are polar and create surface tension through hydrogen bonds, even in vapor form. This explains why clouds are formed. Which postulate of the kinetic molecular theory is untrue for the formation of clouds?
