What would be the solution to 45x - 180 ≤720 be?

2 answers:

7 0

X < or equal to 20

Explanation: We take 180 and add it to 720 to get 900 then with the 45x we divide it we do not flip the signs because 45x is not negative and then we get x is less than or equal to 20

Orlov [11]

Answer:

n=601

Step-by-step explanation:

Formula used:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Solution:

$n=z(\frac{\alpha }{2})^2\frac{p(1-p) }{E^2}$

Where,

$\frac{\alpha }{2}=0.025$

As there is no previous estimate for p

Then, p=0.5

Here on using the table

$z(\frac{\alpha }{2}) =1.959963985$

Also,

E=0.04

p=0.5

Thus,

n=600.2279407

On approximating the value,

n=601
