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

1 answer:

5 0

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.

First Method:

Round $\frac{3}{5}$ to the closest integer, which is 1.

Round $\frac{3}{4}$ to the closest integer, which is also 1.

So 1 + 1 = 2.

Answer for method 1: 2

Second Method:

$\frac{3}{5}$ + $\frac{3}{4}$ = $\frac{3*4}{5*4} + \frac{3*5}{4*5} = \frac{12}{20}+\frac{15}{20}=\frac{27}{20}$

$\frac{27}{20}$ is around 1

Answer for method 2: 1

The closest answer is 1.

3/2x-2=19 What does x equal?

dimaraw [331]

First, add 2 to both sides. You should have 3/2x=21. Multiply both sides by 2 which gives you 3x= 42. Divide by 3 and you have x=14
