How many models does the following set have? 5,5,5,7,8,12,12,12,150,150,150
Strike441 [17]
<h3>Answer:  3 modes</h3>

The three modes are 5, 12, and 150 since they occur the most times and they tie one another in being the most frequent (each occurring 3 times).

Only the 7 and 8 occur once each, and aren't modes. Everything else is a mode. It's possible to have more than one mode and often we represent this as a set. So we'd say the mode is {5, 12, 150} where the order doesn't matter.

Use the confidence level and sample data to find a confidence interval for estimating the population mu. Round your answer to th
inysia [295]

Answer:

c. 9.5 lb < mu < 11.1 lb.

Step-by-step explanation:

Confidence interval can be stated as M±ME where

  • M is the sample mean (10.3)
  • ME is the margin of error

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

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

  • z is the corresponding statistic in 95% confidence level (1.96)
  • s is the standard deviation of the sample (2.4)
  • N is the sample size (37)

Putting thesenumbers in the formula we get:

ME=\frac{1.96*2.4}{\sqrt{37} } ≈ 0.7733 ≈ 0.8

Then the 95% confidence interval would be 10.3 ± 0.8

WILL GIVE BRAINIEST IF CORRECT<br><br> Which of the following doesn't belong? Explain.
Law Incorporation [45]

Step-by-step explanation:

a. 5x² - 80

b. 5(x² + 4x - 4x -16)

5(x² - 16)

5x² - 80

c. 5x² - 20x + 20x - 80

5x² - 80

d. 5x² - 11

D doesn't belong because 5x² - 11 is not the answer to A, B, or C.
