10 / (2/5)...when dividing with fractions, flip what u r dividing by, then multiply
10 * 5/2 = 50/2 = 25...so there are 25 of them
Answer:

Step-by-step explanation:
-Let x be the sample size and n the population size
-The conditions for a one-sample proportion z-test are:
-The sample is randomly selected from the population.
-The sample size is greater than or equal to ten times the population size:

-The expectation np is greater than or equal to 10:

( 2a2 - 2b - 1 ) Is the answer when simplifying the expression.
The solution to the equation is x = 1.62
<h3>How to solve the equation?</h3>
The equation is given as:

Next, we split the equations as follows:
y = x

Next, we graph the equations (see attachment)
From the attached graph, the equations intersect at
(x, y)= (1.62, 1.62)
Remove the y value
x = 1.62
Hence, the solution to the equation is x = 1.62
