How do I alive that problem

Svetach [21]

This can be written as...
(1/2)/(1/4) = h/1

Then you solve all of the fractions by multiplying them by 4 to make them intergers;

4(1/2)/4(1/4) = 2/1 = h/1

This means h is equal to 2.

Hope this helps! :)

-PLEASE ANSWER- An experiment was repeated a number of times and the following measurements were obtained:

gladu [14]

Answer:

Step-by-step explanation:

From the given data, it can be observed that there are two number that are abnormal and extremely different from others, 322 and 19. Eliminating these two numbers would reduce the error that can be generated.

Then to obtain the best single result from the measurements, find the mean of the other numbers.

i.e 52.3, 52.5, 52.2, 52.6

Mean = $\frac{52.3 + 52.5 + 52.2 + 52.6}{4}$

= $\frac{209.6}{4}$

= 52.4

Thus the best single result that can be obtained is 52.4.

If 4g^2 -1= 16h^2 -1, what is the value of g in terms of h?<br> Plz explain

ale4655 [162]

Answer:

g = ±2h

Step-by-step explanation:

4g^2 -1= 16h^2 -1

Add 1 to each side

4g^2 -1+1= 16h^2 -1+1

4g^2 = 16h^2

Divide each side by 4

4/4g^2 = 16/4h^2

g^2 = 4 h^2

Take the square root of each side

sqrt(g^2) = ±sqrt(4h^2)

g = ±sqrt(4h^2)

g = ±2h
