Answer:
number of cubes need : (20/3) / (1/27) = 180 cubes
Step-by-step explanation:
volume of cube = (1/3)^3 = 1/27
volume of prism = 5/3 * 4/3 * 2 = 20/3
<u><em>number of cubes need : (20/3) / (1/27) = 180 cubes</em></u>
<em>9 - 4(2p - 1) =45</em>
<em>5(2p - 1) = 45</em>
<em>10p - 5 = 45</em>
<em>10p = 45 + 5</em>
<em>10p = 50</em>
<em>p = 50/10</em>
<em>p =5 (ans)</em>

Answer:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
Step-by-step explanation:
A confidence interval of a proportion p% at the x% level with m% margin of error means that:
We are x% sure that the true mean of the population is in the interval from (p-x)% to (p+x)%.
In this problem, we have that
90% confidence level
44% with a margin of error of 2%
So:
We are 90% sure that the true proportion of Americans who approve the ppresident's policies is in the interval from 42% to 46%.
