What fraction of the money does Meg get?

Answers

Answer: 1/5 of the money

Step-by-step explanation:

The ratio shows that Kyle gets 3 parts of the money, Meg gets 2 parts of the money, and Dan gets 7 parts of the money. Simple addition lets us know there are 10 parts of the money, and because Meg got 2 of them, she has 2/10ths of the money, or 1/5.

a) 15.8 cm

b) 14.2 cm

c) 12 cm

d) 19.2 cm

[tex] \large \boxed{\mathfrak{Answer \: with \: Explanation} \downarrow}[/tex]

Please refer to the attached picture for the answers with steps included.

NOTE :-

The sides of a rhombus are equal to each other.The point of intersection of the diagonals (marked as O in the figure) forms 90° angles (which is why we used the pythagoras property to solve the question).Since 0 is the point of intersection, it's also the midpoint of the diagonals. (So, BO = ½ × BD & AO = ½ AC -- we used this to solve the question).

The answer the the graph is -2x^2.

In the coordinate plane, point A(-1,-1) is translated to point A' (-3.-3). Under the same translation, the points B(-4,-4) and C(5.-5) are translated to B' and C' respectively. What are the coordinates of B' and C'?

Answers

Answer:

B' (- 6, - 6 ) , C' (- 7, - 7 )

Step-by-step explanation:

Consider the coordinates of A and A'

A (- 1, - 1 ) , A' (- 3, - 3 )

- 1 to - 3 in both the x and y direction means subtracting 2 units , then

translation rule is

(x, y ) → (x - 2, y - 2 ) , then

B (- 4, - 4 ) → B' (- 4 - 2, - 4 - 2 ) → B' (- 6, - 6 )

C (- 5, - 5 ) → C' (- 5 - 2, - 5 - 2 ) → C' (- 7, - 7 )

Based on the segmented bar graph, does there appear to be an associates between grade level and prom theme?

A yes, there is a different number of students in each class.
B yes, it appears that the 12th grade students prefer the 1920s more than the 11th grade students, and prefer the beach party less.
C no, both distributions of student preferences have the same four categories.
D no, both distributions of student preferences have about the same preference for each of the prom themes.
E no, by the same number of students in each class. Preferred winter wonderland and masquerade ball as prom themes.

Answers

Answer:

Step-by-step explanation:

Logically and if you observe the graph closely ┐( ∵ )┌

The answer is yes, there appears to be an association between grade level and prom theme based on the segmented bar graph. The Option B is correct

Is there an association between grade level and prom theme?

The graph shows that 12th-grade students prefer the 1920s theme more than the 11th-grade students do, and they also have a lower preference for the beach party theme. This indicates a difference in preferences between the two grade levels for these specific prom themes.

This graph provide information on whether both distributions have the same four categories or whether they have the same preference for each of the prom themes, so, its indicate whether the number of students in each class is the same or not.

In a batch of 8000 clock radios 5% are defective. A sample of 13 clock radios is randomly selected without replacement from the 8,000 and tested. The entire batch will be rejected if at least one of those tested is defective. What is the probability that the entire batch will be rejected

Answers

Answer:

Step-by-step explanation:

P(A)=1−P(not A)

We can use this here. Event A is that the clock is defective, so Event (not A) means the clock works.

0.02=1−P(not A)

P(not A)=0.98

Therefore, for all the clocks to pass, the probability is P(not A)11.

Now again, we can use complementary counting.

(probability of all clocks failing) = 1 - (probability of all clocks passing)

Probability of all clocks failing = 1−P(not A)11

Answers

Answer:

Step-by-step explanation:

Since B is the midpoint, AB must be equal to BC.

AB = BC

7x - 4 = 3x + 32

Isolate the variable

7x - 4 = 3x + 32

4x = 36

x = 9

Now solve for one side.

AB = 7x - 4

AB = 7(9) - 4

AB = 59

Since both sides are equal, finding AC just means multiplying one side by 2.

AC = AB * 2

AC = (59) * 2

AC = 118

You can double check by finding the other side and multiplying by 2.

BC = 3x + 32

BC = 3(9) + 32

BC = 27 + 32

BC = 59

AC = BC*2

AC = 59*2

AC = 118

Can someone explain how the following Matrix can be multiplied? I thought the column of the first matrix had to match the row of the second and the row of the first had to match the column of the second. I how the matrices listed below as (1x3) and (3x3) respectively. Yet my online Pre-cal course says it's possible. Please explain why this is so.

Answers

You are correct in thinking that the columns of the first matrix must match with the rows of the second matrix.

So for example, we can multiply a 1 x 5 matrix with a 5 x 7 matrix. The two matching '5's are directly what make multiplication possible in this case. For your problem, the first two '3's match and multiplication is possible.

The rows of the first matrix don't need to match with the columns of the second matrix.

It was new with yellow bricks instead of red. It had electricity in all the rooms so at night it lit up the street like a lantern. 2 It was busy all day. There was a baby nursery for mothers who worked, a woodshop to teach boys a trade, and English classes for immigrants. After dark, women would come to ask for food and coal so their children wouldnt starve or freeze. The neighborhood was that poor. 3 Miss Edith Chevalier was in charge of all that and a lot more. Shes the one who started the library groups for girls. Sometimes she would look in and ask what we were readingnot to test us but just because she wanted to know. 4 Thats what happened on the day my club was reading The Midnight Ride of Paul Revere out loud. I guess I was better than the others because after the meeting, Miss Chevalier asked if I would recite the whole poem to the Saturday Club. She said a famous professor was going to give a lecture about Henry Wadsworth Longfellow, and she thought a presentation of his most famous poem would be a nice way to start the evening. 5 She said that I would have to memorize it, But that shouldnt be a problem for a girl of your ability. Im telling you, my feet didnt touch the ground all the way home. It was the biggest thing that ever happened to me and I learned the whole poem by heart in two days so Id be ready for our first rehearsal. 6 Miss Chevalier was a small woman, a few inches shorter than me, which meant less than five feet. She had a moon face and chubby fingers and coppery hair that sprang straight up from her head, which is why some of the girls called her The Poodle. But she had one of those smiles that makes you feel like you just did something right, which was a good thing since I was a nervous wreck when I went to her office to practice. 7 I only got halfway through the poem when Miss Chevalier stopped me and asked if I knew what impetuous meant. She was nice about it, but I wanted to sink through the floor because not only did I not know what the word meant, I had mispronounced it. 8 Im sure I turned bright red, but Miss Chevalier pretended not to notice and handed me the dictionary and said to read the definition out loud. 9 I will never forget; impetuous means two things. Rushing with great force or violence, and acting suddenly, with little thought. 10 She asked me which one I thought Mr. Longfellow meant. I reread those definitions over and over, trying to figure out the right answer, but Miss Chevalier must have read my mind. There is no wrong answer, she said. I want to know your opinion, Addie. What do you think? 11 I had never been asked for my opinion, but I knew I couldnt keep her waiting so I said the first thing that came into my head, which was, Maybe he meant both. 12 She liked that. The patriots had to be impetuous both ways or they wouldnt have dared challenge the British. Then she asked, Would you call yourself impetuous, Addie? 13 That time, I knew she was asking for an opinion. My mother thinks I am. 14 She said mothers were right to be concerned for their daughters welfare. But I believe that girls need gumption, too, especially in this day and age. I believe you are a girl with gumption. 15 After I looked up gumption, I never let anyone call Miss Chevalier The Poodle again. In the selection from The Boston Girl, what does the authors portrayal of Miss Chevalier reveal to the reader? A) Addie's surprise at Miss Chevalier's behavior B) Addie's admiration of Miss Chevalier's personality C) Addie's comfort with Miss Chevalier's criticisms D) Addie's realization of Miss Chevalier's flaws Aashi buys2 packets of bread rolls costing 1.40 for each packet1 bottle of ketchup costing 1.803 packets of sausagesAashi pays with a 10 note.She gets 45p change.Work out the price in pounds () of one pack of sausages.(you will get brainliest) !! :D
