List the sides of the triangle ABC from smallest to largest using the information below. *
Answers
Answer:
AB, BC, AC
Step-by-step explanation:
(9x + 29)° + (93 - 5x)° + (10x + 2)° = 180°
9x + 29 + 93 - 5x + 10x + 2 = 180
14x + 124 = 180
14x = 56
x = 4
m∠A = (9(4) + 29)° = 65°
m∠B = [93- 5(4)]° = 73°
m∠C = (10(4) + 2)° = 42°
m∠C < m∠A < m∠B
AB < BC < AC

Can we predict how fast a tennis player can hit a serve from the playerâs height? The following computer output and scatterplot describe the regression of fastest serve speed (in kilometers per hour) and the height (in meters) of 21 current male professional tennis players.
a. Describe the relationship between height and fastest serve speed for these tennis players.
b. Write the equation of the least-squares regression line. Define any variables used.
c. Interpret the value "R-sq = 27.7%".
d. What is the slope of the least-squares regression line? Interpret this value.
e. Predict the fastest serve of a professional tennis player whose is 1.7 meters tall. Comment on the reliability of this prediction.
f. What is the value of the correlation between height and fastest serve speed? Interpret this value.
g. Calculate the residual for the player that is 2.06 meters tall and has a fastest serve speed of 230 km/hr. Interpret this value.
Answers
Complete question :
The computer output and scatter plot output pertaining to the question can be found in the attached picture.
Answer:
Kindly check explanation
Step-by-step explanation:
A.) Relationship between height and fastest serve speed :
According to the scatterplot and Correlation Coefficient (R) value which can be obtauned by getting the square root of R²
R = √27.7%
R = 0.5263 = 52.63% ; this depicts a fairly strong positive correlation or relationship between height and fastest serve speed
B.)
Equation of least square regression line :
From the computer output and scatter plot above :
Recall :
y = mx + c
y =predicted variable (s fastest serve)
m= slope
x = predictor variable (height)
c = intercept
y = 84.98x + 68.81
C.) 27.7% of the variation in fastest speed can be explained by height while the remaining percentage is due to other variables
D.) fastest serve of tennis player with height 1.7m
y = 84.98x + 68.81
y = 84.98(1.7) + 68.81
y = 213.276km/hr
E.)
R = √27.7%
R = 0.5263 = 52.63% ; this depicts a fairly strong positive correlation or relationship between height and fastest serve speed
F.)
Height = 2.06m = x
y = 84.98(2.06) + 68.81
y = 243.8688 km/hr
Residual = Actual - predicted
Actual = 230 ; predicted = 243.8688
Residual = 230 - 243.8688
Residual = −13.8688
Hence, the model overestimated fastest serve speed of a 2.06 m tall player by −13.8688 km/hr

A wooden artifact from an ancient tomb contains 20 percent of the carbon-14 that is present in living trees. How long ago, to the nearest year, was the artifact made?
Answers
Answer:
The artifact was made approximately 13,306 years ago
Step-by-step explanation:
The half-life of Carbon-14 = 5730 years
The formula for radioactive decay is given by the equation:
[tex]N=N_0 e^{- \lambda t}\\where:\\N = Number\ of\ particles\ at\ time\ t\\N_0= Number\ of\ particles\ at\ time\ t_0\\\lambda = decay\ constant = \frac{In}{t_{1/2}} ; t_{1/2} = half-life\\t = time\ in\ years[/tex]
The amount of Carbon-14 left = 20% = 20/100 = 0.2
[tex]\therefore \frac{N}{N_0} = 20 \% = 0.2[/tex]
[tex]N=N_0 e^{- \lambda t}\\\\dividing\ both\ sides\ by\ N_0\\\frac{N}{N_0} = e^{- \lambda t}\\0.2 = e^{- \lambda t}\\taking\ natural\ logarithm\ of\ both\ sides\\In 0.2 = Ine^{- \lambda t}\\In0.2 = -\lambda \times t\\but\ \lambda = \frac{In2}{t_{1/2}} \\\therefore In0.2 = -\lambda \times t\\\\= In0.2 = - \frac{In2}{t_{1/2}} \times t\\where\ t_{1/2} = 5730\ years\\-1.6094 = - \frac{0.6931}{5730} \times t\\-1.6094 = - 0.00012095 \times t\\t = \frac{-1.6094}{-0.00012095} \\t = 13,306.32[/tex]
t ≈ 13,306 years

When Noah goes bowling, his scores are normally distributed with a mean of 150 and a standard deviation of 12. What is the probability that the next game Noah bowls, his score will be between 135 and 167, to the nearest thousandth?
Answers
Answer:
The probability of his score being between 135 and 167 is 0.8151 or (0.8151*100=81.51%)
Step-by-step explanation:
Given that:
Mean = μ = 150
SD = σ = 12
Let x1 be the first data point and x2 the second data point
We have to find the z-scores for both data points
x1 = 135
x2 = 167
So,
[tex]z_1 = \frac{x_1-mean}{SD}\\= \frac{135-150}{12}\\=\frac{-15}{12}\\=-1.25[/tex]
And
[tex]z_2 = \frac{x_2-mean}{SD}\\z_2 =\frac{167-150}{12}\\=\frac{17}{12}\\= {1.416}[/tex]
We have to find area to the left of both points then their difference to find the probability.
So,
Area to the left of z1 = 0.1056
Area to the left of z2 = 0.9207
Probability to score between 135 and 167 = z2-z1 = 0.9027-0.1056 = 0.8151
Hence,
The probability of his score being between 135 and 167 is 0.8151 or (0.8151*100=81.51%)

When employing the scale factor, there are two terms that must be understood. When a figure's size is increased, we refer to this as scaling up, and when its size is decreased, we refer to this as scaling down.
Given:

The mean per capita income is 21,604 dollars per annum with a standard deviation of 727 dollars per annum. What is the probability that the sample mean would differ from the true mean by less than 36 dollars if a sample of 193 persons is randomly selected
Answers
Answer:
The probability that the sample mean would differ from the true mean by less than 36 dollars is 0.7549.
Step-by-step explanation:
According to the Central Limit Theorem if an unknown population is selected with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from this population with replacement, then the distribution of the sample means will be approximately normally.
Then, the mean of the sample means is given by,
[tex]\mu_{\bar x}=\mu[/tex]
And the standard deviation of the sample means is given by,
[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]
The information provided is:
[tex]\mu=21604\\\sigma=727\\n=193[/tex]
As the sample size is large, i.e. n = 193 > 30 the central limit theorem can be used to approximate the sampling distribution of sample mean per capita income.
Compute the probability that the sample mean would differ from the true mean by less than 36 dollars as follows:
[tex]P(\bar X-\mu<36)=P(\frac{\bar X-\mu}{\sigma_{\bar x}}<\frac{36}{727/\sqrt{193}})\\\\=P(Z<0.69)\\\\=0.7549[/tex]
Thus, the probability that the sample mean would differ from the true mean by less than 36 dollars is 0.7549.

Sin Qua Corporation is a company listed on the stock exchange and issues corporate bonds. Which statement is most likely true?
A.
Investors can buy the bonds directly from the government.
B.
Investors will have to pay tax on the interest income received from the bonds.
C.
The bond pays a quarterly dividend at a specified percentage of the investment.
D.
The bond’s price is linked to the company stock price.
E.
The bond’s maturity date is determined by the company’s creditworthiness.
Answers
Answer:
B. Investors will have to pay tax on the interest income received from the bonds.
Explanation:
Interest earned from corporate bonds and capital gained through corporate bond transactions is taxable income. The interest earned from a corporate bond is subject to taxation by both the federal and state governments.
The government will not sell sin Qua corporation bonds as it is a public company. Bonds do not pay interest quarterly but rather semi-annually or annually. Again, the maturity of the bond is determined at the time they are issued. Creditworthiness will only affect the bond price but not its maturity period.
Investors will have to pay tax on the interest income received from the bonds is thus the correct statement.

Isolate x or y in the first equation
Isolating for x would be x= -y+2000
Substitute X=-y+2000 into equation 10x+20y=35000
10(-y+2000)+20y=35000
Exapnd the equation above and you should get y=1500

(Round your answer to the nearest cent.)
p = 7 + 2q1⁄3; p = 20
Answers
Answer:
Step-by-step explanation:
Given the equation of the unit price expressed as;
p = 7 + 2q1⁄3, we are to find the value of q when p = 20
20 = 7 + 2q1⁄3
20-7 = 2q/3
13 = 2q/3
Cross multiply
13 * 3 = 2q
39 = 2q
q = 39/2
q = $19.5
Hence the producer surplus is 1950 cents

He hopes to have an B quiz average (80 or above).
We need to find the lowest score John can make on his fourth and final project. Let the score is x.
Average = sum of numbers/total numbers
[tex]80=\dfrac{77+76+84+x}{4}\\\\320=237+x\\\\x=83[/tex]
So, he must score 83 or more on his fourth project so as to make average 80 re above.
