Ron lives 6 miles due north of the ball field, and Stan lives 8 miles due west of the ball field. What is the straight line distance between their homes? (It makes a right triangle.)8 miles


10 miles


20 miles


50 miles

Answers

Answer 1
Answer: You would use Pythagoras' theorem (a^2 + b^2 = c^2) because it is a right-angled triangle. 6^2 + 8^2 = 36 + 64 = 100. √100 = 10. So your answer is 10 miles, I hope this helps!
Answer 2
Answer: I think it's 20 miles but I don't know if it is

How many solutions are possible for a triangle with B=44,a=23,=12?

Answers

b/sinB = a/sinA 

12/sin44 = 23/sinA

12sinA = 23*sin44

sinA = (23*sin44)/12

sinA = 1.3314

Which of the following conditions must be met if you want to use a z-procedure to construct a confidence interval for a population proportion? A) The sample size must be small. B) The population standard deviation must be known. C) The population must be normally distributed. D) The sample must be random and sufficiently large.

Answers

To use a z-procedure to construct a confidence interval for a population proportion, the following conditions must be met:

D) The sample must be random and sufficiently large.

This means that the sample should be selected in a way that each individual has an equal chance of being included. Additionally, the sample size should be sufficiently large to ensure that the normal approximation for the sampling distribution of the sample proportion is valid.

It's important to have a random sample because it helps to ensure that the sample is representative of the population, making the results more reliable and generalizable.

As for the sample size, it should be large enough to satisfy the condition of having at least 10 successes and 10 failures. This ensures that the normal approximation can be applied.

The other answer choices, A) The sample size must be small, B) The population standard deviation must be known, and C) The population must be normally distributed, are incorrect and do not apply to the conditions for using a z-procedure to construct a confidence interval for a population proportion.

By meeting the conditions of having a random and sufficiently large sample, you can use a z-procedure to construct a confidence interval for a population proportion.Answer:

Dustin says that FGH is an equilateral triangle because the sides appear to be the same length.Is his reasoning valid?Explain

Answers

His reasoning is not valid because they might actually appear to be equal to his sight, but should he measure them they might not exactly be.

So he just can't look at it and conclude. He can say it is equilateral if each angles measures 60 degrees.
