Lydia graphed δlmn at the coordinates l (0, 0), m (2, 2), and n (2, −1). She thinks δlmn is a right triangle. Is lydia's assertion correct?.
Answers
No product results in -1, hence δlmn is NOT a right triangle showing that lydia's assertion is incorrect
Perpendicular linesIn order to determine whether triangle lmn is right-angled, we need to determine the slope of lm, ln, and mn first as shown:
For the slope of lm:
\(m_{lm} = \frac{2-0}{2-0}\\ m_{lm} =2/2\\m_{lm} =1\)
For the slope of ln:
\(m_{ln} = \frac{-1-0}{2-0}\\m_{ln} =-1/2\\\)
For the slope of mn:
\(m_{mn} = \frac{-1-2}{2-2}\\m_{ln} =-3/0 = \infty\\\)
If any of the two lines is perpendicular, hence the triangle lmn is right-angled.To check, we will take the product of the slopes and see if it is equivalent to -1.Product of slope lm and ln
\(m_{lm}\times m_{ln} = 1 \times -1/2\\m_{lm}\times m_{ln} = -1/2\)
Since no product results in -1, hence δlmn is NOT a right triangle showing that Lydia's assertion is incorrect

[3 pts] Make a scatterplot and describe the association between % Fast Connection and Hours Online. Include all 4 characteristics and the correlation coefficient
Answers
To create a scatterplot, we can plot the percent of internet users with a "fast" connection on the x-axis and the average amount of time spent online in hours per week on the y-axis.
scatterplot
The scatterplot shows a positive association between % Fast Connection and Hours Online. As % Fast Connection increases, there is generally an increase in Hours Online.
The association appears to be fairly strong, as the points cluster relatively tightly around the line of best fit.
There is no apparent non-linear pattern in the data, as the points do not seem to follow a curve or any other non-linear shape.
The correlation coefficient between % Fast Connection and Hours Online is r = 0.864, indicating a strong positive correlation between the two variables.

The breaking strengths of cables produced by a certain manufacturer have a standard deviation of 92 pounds. A random sample of 90 newly manufactured cables has a mean breaking strength of 1700 pounds. Based on this sample, find a 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer. Then give its lower limit and upper limit. Carry your intermediate computations to at least three decimal places. Round your answers to one decimal place
Answers
Answer:
To find the 95% confidence interval for the true mean breaking strength of all cables produced by the manufacturer, we can use the formula:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
First, let's calculate the standard error, which is the standard deviation divided by the square root of the sample size:
Standard Error = Standard Deviation / √(Sample Size)
= 92 / √(90)
≈ 9.685
Next, we need to determine the critical value corresponding to a 95% confidence level. Since the sample size is large (n > 30), we can use the z-table. The z-value for a 95% confidence level is approximately 1.96.
Now we can calculate the confidence interval:
Confidence Interval = Sample Mean ± (Critical Value * Standard Error)
= 1700 ± (1.96 * 9.685)
Lower Limit = 1700 - (1.96 * 9.685)
≈ 1679.69
Upper Limit = 1700 + (1.96 * 9.685)
≈ 1720.31
Therefore, the 95% confidence interval for the true mean breaking strength of all cables produced by this manufacturer is approximately (1679.7, 1720.3). The lower limit is 1679.7 pounds, and the upper limit is 1720.3 pounds.
(x-7)(x-s)=x2-rx+14, for all values of x, what is the value of r+s?
Answers
Answer:
r+s = 11
Explanation:
we know from formula
(x-a)(x-b) = x2-(a+b) x + ab
now
from
(x-7)(x-s)=x2-rx+14
ab = 7s = 14
=> s=2
and
a+b = 7+s = r
=> 7+2 = r
=> r = 9
so
s+r =2+9 = 11
