Is finding the mean weight of heart-disease patients in a study an example of data gathering?
Leviafan [203]

I would think so since you have to weigh each person and then add all the weights together and then divide this number by the total number of people weighed.

Would probably mostly hinge on the actual weighing part I think for the data gathering.

A fair coin is tossed 5000 times. What can you say about getting the outcome of exactly 2500 tails
WINSTONCH [101]

Step-by-step explanation:

You can't expect to get exactly 2500 out of 5000 tosses more than a few times . You will come pretty close, but that's only good in horseshoes.

Of course I'm answering this on the basis of a computer language and not actually performinig this a million tmes, each part of a million consisting of 5000 tosses.

Simulations and not completely unbiased, but based on experience, 5000 is a very small number and getting 2500 more than a couple of times is unlikely

I will give BRAINLIEST to the correct answer <br> Find the measure of angle 6.
True [87]

Answer:

m∠6 = 116°

Step-by-step explanation:

<u>first find x:</u>

7x - 17 = 2x + 78

subtract 2x from both sides: 5x - 17 = 78

add 17 to both sides: 5x = 95

divide by 5: x = 19

<u>plug x into 7x - 17</u>

7(19) - 17 = 116

∠6 and 7x - 17 are vertical angles and therefore congruent, so m∠6 also = 116°
