ExamAABC ~ AQRSFind The Missing Side Length, M.B10m69m = [?]

Answers

Answer 1

Answer:

m = 15

Step-by-step explanation:

Since ∆ABC ~ ∆QRS, this implies that the ratio of their corresponding side lengths are equal. Thus:

QR/AB = QS/AC

QR = m

AB = 10

QS = 9

AC = 6

Plug in the values

m/10 = 9/6

m/10 = 3/2

Cross multiply

2*m = 3*10

2m = 30

m = 30/2

m = 15

The height of a plant in centimeters is recorded each day for 10 days. The function y = 1.73x + 1.87 is determined to
be a good fit for the data. On day 6 the recorded height was 12.5 cm. How close is the predicted height to the actual
height of the plant (the residual)?
15 points

Answers

Answer: 0.25 cm

Step-by-step explanation: The function y = 1.73x + 1.87 is used as a prediction. Since the answer is asking for how close the predicted height to the actual height is on day 6, we substitute 6 for x.

The function becomes like this:

y = 1.73(6) + 1.87

y = 10.38 + 1.87

y = 12.25

y = 12.25 cm is the predicted height on day 6. The actual height on day 6 recorded is 12.5 cm. We subtract the predicted height from the actual height and get 0.25 cm.

Lucy Baker is analyzing demographic characteristics of the American Idol program. Previous studies indicate that the average viewer is 43 years old. May changes took place in the program and there are rumors the audience has changed. Mrs. Baker was tasked to find out . She randomly selects 100 people from the audience, and reports that the average age is 45 years. Assuming that variability in the ages of viewers is σ = 5 years, identify if Mrs. Baker's conclusion. She wants to accept a Type I error of .05.

Answers

Answer:

We conclude that the mean age of average viewer has changed

Step-by-step explanation:

H0 : μ = 43

H1 : μ > 43

The test statistic :

(xbar - μ) ÷ σ/sqrt(n)

Sample size, n = 100

xbar = 45 ; σ = 5

Test statistic :

(45 - 43) ÷ 5/sqrt(100)

2 ÷ 0.5 = 4

The Pvalue :

P(Z < 4) = 0.000032

Pvalue < α

0.000032 < 0.05 ; Hence, we reject the Null

We conclude that the mean age of average viewer has changed

2. Since the triangles are equal if they share two side lengths with the same angle between them, if they changed the angle between 3 and 5, it'd no longer be the same triangle.

Read this passage by Mawi Asgedom and answer the question that follows:Hi, my name is Mawi Asgedom. I'm excited to offer this class to you for one simple reason. That's because I believe you are far more intelligent, far smarter than you know. And the reason I believe that is, I lived it in my own life. See, I was born in Ethiopia; in my homeland there was a war so I became a refugee and I had to come to this country when I was seven years old. I didn't know any English when I came. I went to first grade, it was really hard. I didn't know the alphabet, I didn't know what to do in class. I looked around and thought, man, I can't be successful like these other kids. My family had also grown up in poverty, grew up on welfare from first to twelfth grade, my father was legally blind. I thought I couldn't do it. Fast forward to eighth grade, I had a D in my math class; I got Cs in some of my classes. I got kicked off my basketball team, I had a lot of challenging problems, I didn't have a lot of confidence.Well, in high school something changed. I acquired some study skills, my mindset changed. Guess what guys? I became an A student. I became a top athlete in sports. And in my senior year of high school, something incredible happened, I couldn't have imagined. I got over three hundred thousand dollars worth of scholarships, I got into every college I applied to. I ended up going to Harvard University, the number one university in the United States, some people say the world. When I was at Harvard, I got As while I was there.What I figured out, what I learned, is that any student, of any background, can be successful, whether you are rich or poor. For those of you that are out there thinking, well Mawi, I'm not that smart, I can't make it, I'm always struggled in school. In this class, I'm going to show you how to achieve and do things you never thought possible in the classroom. You're going to find out you're a lot more intelligent, a lot smarter than you ever knew and I'm going to show you how. For those of you out there who are great students, who say Mawi I've already got this, guess what, I spent four years at Harvard with some of the best students on the planet and I learned a lot of things from my own journey too. I've worked with more than a million students over the last fifteen years and if you are a good student right now, I'm going to make you better. This class will make you better.Read the following statement: Well, in high school something changed. I acquired some study skills, my mindset changed.What evidence did Mawi use to support this statement? He started earning A's, became a top athlete, and was accepted to Harvard. He believes that any student, from any background, can become successful. He got a D in math class, C's in other classes, and got kicked off the basketball team. He was a refugee from Ethiopia, grew up in poverty, and had low self-confidence. On her 21st birthday, Sydney deposited $400 in a new bank account that earns 3.7% interest compounded continuously.
