This line segment will be dilated with the point of dilation at (4,1) and scale factor of 2. What is the x-coordinate of one of
IgorLugansk [536]

Answer:

<h3>8</h3>

Step-by-step explanation:

If a coordinate point (x, y) is dilated by a factor k, then the resulting coordinate will be (kx, ky)

Given the coordinate (4,1), if this coordinate is dilated by a factor of 2 then the new coordinate points will be at (2(4), 2(1))

New point = (8, 2)

Hence  x-coordinate of one of the the end point of the dilated segment is 8

Find the values of x and y. Leave answers in simplest radical form.<br>​
NNADVOKAT [17]

\sin(60°) =  \frac{x}{14}  \Leftrightarrow x = 14 \sin(60°) =  \frac{14 \sqrt{3} }{2}  = 7 \sqrt{3}  \\  \cos(60°)  =  \frac{y}{14} \Leftrightarrow y = 14\cos(60°) =  \frac{14}{2}  = 7

An electric sale gives a reading equal to the true weight plus a random error that isnormally distributed with mean 0 and standa
Pepsi [2]

Answer:

a) 95% confidence interval estimate of the true weight is (3.026, 3.274)

b) 99% confidence interval estimate of the true weight is (2.944, 3.356)

Step-by-step explanation:

Confidence Interval can be calculated using M±ME where

  • M is the mean of five successive weightings (3.150)
  • ME is the margin of error from the mean

And margin of error (ME) can be calculated using the formula

ME=\frac{t*s}{\sqrt{N} } where

  • t is the corresponding statistic in the given confidence level and degrees of freedom(t-score)
  • s is the standard deviation of the random error (0.1)
  • N is the sample size (5)

Using the numbers 95% confidence interval estimate of the true weight is:

3.150±\frac{2.776*0.1}{\sqrt{5} }≈3.150±0.124

And 99% confidence interval estimate of the true weight is:

3.150±\frac{4.604*0.1}{\sqrt{5} }≈3.150±0.206
