Step-by-step explanation:
From given data,
n = 1496
x = 478
Proportion estimate ( p ) = 
=
= 0.3195 ≅ 0.31
Proportion estimate ( p ) = 0.31
∴ The proportion of new car buyers who prefer foreign cars -> 0.31
Considering the graph of the cube root parent function, it is found that the correct statement is given by:
D. It is always increasing.
<h3>When a function is increasing?</h3>
A function is increasing when the vertical axis of the graph gets higher as we move the horizontal axis from left to right.
In this problem, the above statement is true for the entire function, hence option D is correct.

Answer:
105/8 inch^3
Step-by-step explanation:
7/2*5/2*/3/2 = 105/8
The answer can be readily calculated using a single variable, x:
Let x = the amount being invested at an annual rate of 10%
Let (8000 - x) = the amount being invested at an annual rate of 12%
The problem is then stated as:
(x * 0.10) + ((8000 - x) * 0.12) = 900
0.10(x) + ((8000 * 0.12) - 0.12(x)) = 900
0.10(x) + 960 - 0.12(x) = 900
0.10(x) - 0.12(x) = 900 - 960
-0.02(x) = -60
-0.02(x) * -100/2 = -60 * -100/2
x = 6000 / 2
x = 3000
Thus, $3,000 is invested at 10% = $300 annually; and $8,000 - $3,000 = $5,000 invested at 12% = $600 annually, which sum to $900 annual investment.
